Finding the Funds: How to Budget $50 to $100 a Month for Your Child’s Future

Almost every new parent wants to save for their child’s future. Far fewer can see where the money would come from. Full-time child care averaged $13,184 a year nationally in 2025, according to Child Care Aware of America, and diapers alone can run $80 to $100 a month per baby. When every dollar already feels spoken for, “start investing” can sound like advice meant for someone else.

The amount that matters is smaller than most parents think. At a hypothetical 7% average annual return, $50 a month invested from birth grows to about $21,000 by age 18, and $100 a month grows to about $42,100. That’s $1.64 to $3.29 a day. You don’t need a raise or a spending overhaul to find it. For most families, the money is already in the budget, tied up in a forgotten subscription, a paycheck withholding setting that hasn’t caught up with the baby, or a bill that costs more than it needs to.

This guide, part of our Ultimate Guide to Building a Generational Nest Egg for Your Child, shows you where to look. You’ll see which tax and benefit changes come with a new baby, which everyday costs are easiest to trim, how to save on baby gear without cutting corners on safety, and how to make the transfer happen automatically.

Why $50 to $100 a month is enough to matter

It’s tempting to think a child’s nest egg needs hundreds of dollars a month to be worth starting. It doesn’t. What matters most is time. Money invested in a child’s first years has nearly two decades to compound, so modest monthly amounts grow into meaningful sums.

Hypothetical example: deposits at the end of each month from birth through age 18, a 7% average annual return compounded monthly, and no fees or taxes. Not a prediction or guarantee.

In every row, about half of the balance at 18 is investment growth rather than money you set aside. That’s why the first few years count for so much, and why waiting until the budget feels roomier is expensive. Starting at birth instead of age 10 more than triples what $100 a month becomes by 18, as we show in The Cost of Waiting.

These figures use the same hypothetical 7% average annual return, compounded monthly, as the rest of the GoodNest library. That’s below the stock market’s long-run average, to allow for fees and a gradual shift toward safer investments as college approaches. No return is guaranteed, and real markets rise and fall along the way. If $50 isn’t realistic yet, start with $25, or even $10. You can raise the amount as your budget allows. The habit matters more than the starting number.

Start with a 30-day spending check

You can’t redirect money you can’t see. Before you cut anything, spend 20 minutes with the last 30 days of bank and credit card statements, or 90 days if you can. Sort each charge into three groups: fixed bills like housing, insurance, and loan payments; flexible spending like groceries, dining out, and shopping; and recurring charges that renew on their own, like streaming services, apps, memberships, and delivery passes. If you’d rather work on paper, the Consumer Financial Protection Bureau’s free Your Money, Your Goals toolkit includes a printable spending tracker.

National figures show how small $100 is next to a typical budget. The average U.S. household spent $78,535 in 2024, or about $6,545 a month, according to the Bureau of Labor Statistics’ Consumer Expenditure Survey. Redirecting $100 a month means moving about 1.5% of that. The same survey found that the average household spent $3,945 on food away from home, a category that includes takeout and delivery, along with $3,609 on entertainment and $1,993 on vehicle insurance. Those three categories alone come to nearly $800 a month.

Pick a budgeting method you’ll actually use

The best budget is the one you’ll keep using when you’re short on sleep. Three approaches work well for new parents:

• Pay yourself first. Treat your child’s savings like a bill. Pick an amount, schedule it for payday, and budget with what’s left. It takes the least upkeep, which makes it a good fit for the newborn months.
• The 50/30/20 guideline. Popularized by Elizabeth Warren and Amelia Warren Tyagi in their 2005 book All Your Worth, it splits take-home pay into 50% for needs, 30% for wants, and 20% for savings and debt payoff. With a new baby, needs often run past 50% for a while, so treat the split as a direction to move in rather than a test you pass or fail.
• Zero-based budgeting. Give every dollar a job before the month starts, including a line for your child’s account. It takes more effort, but it shows exactly where each dollar goes.

Where $100 a month can come from

Most families won’t find $100 in a single place, and they don’t need to. The chart shows what seven common moves could free up each month, based on national averages. No single everyday trim reaches $100 on its own, but three of the larger ones together can, and all five total about $170 a month. For families who qualify, one tax or benefit move can cover the whole goal by itself.

• Tax and benefit moves, if you qualify

Illustrative monthly amounts based on national averages. Your results will differ. The FSA figure assumes $7,500 of child care costs, the 22% federal tax bracket, and 7.65% Social Security and Medicare taxes. The W-4 figure is the $2,200 Child Tax Credit for one child, spread over 12 months.

Your numbers will differ. A family that rarely orders takeout won’t save much there, while a family paying for four streaming services might save more on subscriptions alone. The point is to look in several places at once. Each move is explained below.

Tax and benefit moves for new parents

A new baby changes your taxes and your workplace benefits, often in your favor. These moves don’t require spending less on anything. They put money you’re already entitled to back into your monthly cash flow.

Update your W-4 for the Child Tax Credit

For 2026, the Child Tax Credit is worth up to $2,200 per qualifying child under age 17, and up to $1,700 of it is refundable, according to the IRS’s 2026 inflation adjustments. If you don’t tell your employer about your new child, you’ll still get the credit, but not until you file your tax return the following year.

Step 3 of the 2026 Form W-4 changes that. If your total income will be $200,000 or less ($400,000 or less if married filing jointly), you multiply the number of qualifying children under 17 by $2,200 and enter the result, and your employer withholds that much less tax over the year. For one child, that’s up to about $183 a month more in your paychecks. The IRS suggests checking your withholding after a birth or adoption, and its free Tax Withholding Estimator can create a filled-in W-4 for you.

This isn’t extra money. It’s the credit you’d receive anyway, arriving monthly instead of at tax time. That’s exactly what makes it useful. Set up an automatic transfer for part of it that starts with the same paycheck, and your child’s account grows without your take-home pay ever feeling smaller. Two cautions: if you and your spouse both work, claim the credit on only one W-4, as the form instructs, because claiming it on both cuts your withholding twice and can leave you owing at tax time. And run the estimator rather than guessing, especially if your income is close to the limits.

Use a dependent care FSA if you pay for child care

If your employer offers a dependent care flexible spending account (FSA), you can pay for child care with pre-tax dollars. Starting in 2026, the most a household can exclude from income rose from $5,000 to $7,500 a year ($3,750 if married filing separately), under federal tax law as amended by the One Big Beautiful Bill Act. Because the money skips federal income tax as well as Social Security and Medicare taxes, a family in the 22% bracket that uses the full $7,500 saves about $2,224 a year in federal taxes, roughly $185 a month. In the 12% bracket, the savings come to about $1,474 a year, or $123 a month. Any state income tax savings come on top.

A few catches apply. The higher limit is optional for employers, so your plan’s maximum may still be $5,000 unless your employer has adopted the new cap, as Summit Health Benefits explains. You also can’t count the same expenses twice: money you run through the FSA reduces the expenses you can use for the Child and Dependent Care Credit, according to the IRS, so lower-income families should compare the two. Most employers hold open enrollment in the fall, and many plans also let you enroll or change your election after a birth or adoption. Once the tax savings show up in your paycheck, send them to your child’s account before they blend into everyday spending.

Ask HR about Trump Account contributions

Starting July 4, 2026, employers can contribute up to $2,500 a year per employee, tax-free, to the Trump Accounts of employees’ children. The limit applies per employee, not per child, and it counts toward each account’s $5,000 annual contribution limit, according to the law firm Ropes & Gray. Some employers have announced programs, so ask whether yours offers one. Separately, children who are U.S. citizens with a Social Security number and were born from January 1, 2025, through December 31, 2028, can receive a one-time $1,000 federal deposit when a parent makes the election on IRS Form 4547, according to the IRS. Neither one costs you anything, and both give your monthly contributions a head start.

Give your tax refund a job

Refunds grew this year. The average refund was about $3,275 through mid-April 2026, up 11% from a year earlier, according to IRS filing season statistics. You don’t have to wait for a refund to hit your checking account before moving it. When you file, you can split a direct-deposit refund among up to three accounts at U.S. financial institutions, the IRS says, so part of it lands in savings before it can be spent. At a hypothetical 7% return, sending $1,000 of each year’s refund to your child’s account for 18 years would grow to about $34,000. If you get a big refund every year, you can also go the other way: adjust your withholding and turn the refund into a monthly transfer.

Everyday trims that add up

Each of these moves takes one phone call or one evening, and most keep paying off every month after that.

Audit your subscriptions

Subscriptions are built to be forgotten. In CNET’s 2026 subscription survey, the average adult spent $111 a month on subscriptions, up 23% from a year earlier, and wasted $252 a year, about $21 a month, on subscriptions they didn’t use, WFSB reported. Open the subscriptions page in your phone’s app store, then scan your card statements for anything that renews monthly or yearly. Cancel what you don’t use, rotate streaming services instead of paying for them all at once, and move to a family plan wherever two of you pay separately. Canceling just the unused ones could free up about $21 a month.

Waste less food before you buy less food

Before you cut what your family eats, cut what it throws away. The average family of four wastes about $2,913 worth of food a year, roughly 11% of what it spends on food, according to a 2025 Environmental Protection Agency report. That’s about $243 a month. Planning meals around what’s already in the fridge, shopping with a list, freezing leftovers before they turn, and keeping an “eat this first” shelf all make a dent. Wasting a quarter less would free up about $61 a month without changing the menu.

Make takeout a planned treat

Food away from home cost the average household $3,945 in 2024, about $329 a month. Tired new parents lean on takeout for good reason, so don’t try to cut it out. Instead, decide in advance how many takeout nights fit your budget, and skip the ones that happen only because the day ran long. Trimming 10% saves about $33 a month, and picking up the order yourself avoids delivery fees and tips.

Re-shop your car insurance

Car insurance has climbed fast. Average household spending on vehicle insurance rose 12.3% in 2024, after an 11.5% jump in 2023, to $1,993 a year, according to the BLS. Prices vary a lot from one insurer to the next, so get several quotes at renewal. Texas’s Office of Public Insurance Counsel also suggests bundling policies, asking about discounts, and considering a higher deductible. A higher deductible lowers your premium but raises what you’d pay after an accident, so choose one only if your emergency savings could cover it.

Right-size your phone plan

Smaller carriers, known as mobile virtual network operators, rent space on the same networks the major carriers run and usually charge less. Switching could save up to $500 a year, according to Consumer Reports, which works out to about $42 a month. Check how much data you actually use before you shop, since many people pay for more than they need.

Stop paying your bank

Account fees are among the easiest costs to eliminate. The average interest-bearing checking account charges $15.65 a month, while 95% of non-interest checking accounts are free or become free with direct deposit, according to Bankrate’s 2025 fee study. The same study put the average cost of an out-of-network ATM withdrawal at a record $4.86. Moving to a free account and sticking with in-network ATMs can save about $16 a month, or more if you pay ATM fees regularly.

Save on baby costs without cutting corners on safety

Babies outgrow clothes, gear, and toys within months, which makes secondhand shopping one of the easiest ways to trim the baby budget. Accept hand-me-downs, shop consignment and resale sites, and sell what your child has outgrown. Then send the proceeds to your child’s account instead of your checking account.

Two items deserve extra care:

• Car seats. Safety advocates don’t recommend buying used car seats, because a seat can have crash damage you can’t see, and seats expire and get recalled, according to the New York Governor’s Traffic Safety Committee. Use a secondhand seat only if you know its full history: never in a crash, all parts and instructions present, not expired, and not recalled.
• Cribs. Since June 28, 2011, every crib made or sold in the U.S., including resales, has had to meet stronger federal safety standards, and you can’t tell by looking whether an older crib complies, according to the Consumer Product Safety Commission. Skip cribs made before that date, including drop-side designs.

If you use infant formula, store brands are worth a look. All infant formula sold in the U.S. must meet the same federal requirements for safety and nutrition, including minimum levels of 30 nutrients, according to the Food and Drug Administration. Store brands usually cost less than the big names. Check with your pediatrician before switching.

Turn finished baby expenses into savings

Some of the biggest costs of early parenthood come with an end date. Diapers can run $80 to $100 a month per baby, according to the National Diaper Bank Network, and they stop after potty training. Formula ends. Full-time child care, which averaged about $1,099 a month in 2025, often falls when your child starts free public school, even if before- and after-school care continues.

When one of those bills disappears, the money usually gets absorbed into everyday spending within a month or two. Instead, keep paying it, just to a different place: redirect part or all of the old amount to your child’s account on the same day the bill used to come out. At a hypothetical 7% return, $50 a month from birth, plus another $100 a month starting at age 5, when child care costs fall for many families, would grow to about $46,000 by age 18.

The same idea works for raises. In the first company to adopt the Save More Tomorrow program, designed by economists Richard Thaler and Shlomo Benartzi, employees committed in advance to saving part of each future raise. Those who joined raised their average savings rate from 3.5% of pay to 13.6% over about 40 months, the authors reported in the Journal of Political Economy. Deciding now to send part of your next raise to your child’s account works the same way: you save more without ever seeing your take-home pay shrink.

Make it automatic

Finding the money is only half the job. The other half is making sure it actually moves. The most reliable approach is to pay yourself first: schedule an automatic transfer to your child’s account for the day after payday, so the money leaves before everyday spending can claim it. Most 529 plans and brokerage firms let you set up recurring contributions from your checking account in a few minutes.

If you’ve found money in several places, you don’t need several transfers. Add up what you freed, round down, and set one monthly amount. Revisit it once a year, or whenever something changes, like a raise, a new bill, or an expense that ends. Our guide to automating the nest egg walks through the setup step by step.

Choose where the money goes

Starting matters more than finding the perfect account, but it helps to choose one on purpose. A 529 plan offers tax-free growth for education and, in many states, a state income tax deduction or credit for contributions. A custodial UTMA or UGMA account can be used for anything that benefits your child, but the money legally belongs to your child, who takes control at an age your state sets. A Trump Account works like an IRA for your child, with a $5,000 annual contribution limit and the $1,000 federal deposit for eligible children. Our account comparison explains the tradeoffs.

Protect the basics first

Saving for your child works best when your own finances are on solid ground. Before you send money to a child’s account, cover three things:

• A small emergency cushion. Even a few hundred dollars in savings can keep a surprise bill from landing on a credit card.
• Your employer’s retirement match. A match is part of your pay. Giving it up to fund a child’s account usually costs more than it gains, as we explain in The “Oxygen Mask” Rule of Parental Finance.
• High-interest debt. Credit card accounts that were charged interest paid an average rate of 22.15% in the second quarter of 2026, according to the Federal Reserve. Paying down a balance at that rate is a guaranteed return that a hypothetical 7% can’t match.

That doesn’t mean waiting until everything is perfect. While you work on these, a small automatic amount for your child, even $10 or $25 a month, keeps the habit alive until the rest of your plan catches up. Free money, like the $1,000 Trump Account deposit or a relative’s birthday gift, can go straight to your child’s account in the meantime.

Where GoodNest fits

Your budget doesn’t have to do all the work. Grandparents, aunts, uncles, and friends already spend money on your child every birthday and holiday, often on toys that are outgrown within months. At a hypothetical 7% return, $200 a year in birthday contributions, starting at your child’s first birthday, would grow to about $6,600 by age 18.

GoodNest lets family and friends mark birthdays and milestones with a contribution toward your child’s future, often paired with a small keepsake like a book, instead of another toy. GoodNest doesn’t hold or invest the money. Family send gifts straight to you by Zelle, Venmo, or PayPal, and you move them into the 529 plan, custodial account, or Trump Account you’ve chosen. Combine those gifts with your automatic monthly transfer, and your child’s nest egg grows from two directions at once.

The bottom line

You don’t need a bigger paycheck to start your child’s nest egg. For most families, $50 to $100 a month is already in the budget. Look first at the tax and benefit changes that come with a new baby, then trim a few recurring costs you won’t miss, buy baby gear secondhand where it’s safe, and keep paying yourself when a baby expense ends. Make the transfer automatic and let time do the heavy lifting. At a hypothetical 7% return, $100 a month could be worth about $42,100 by the time your child turns 18.

Frequently asked questions

How much should I save for my child each month?

There’s no single right amount, but $50 to $100 a month is a realistic target for many families and grows into a meaningful sum. At a hypothetical 7% average annual return, $50 a month invested from birth grows to about $21,000 by age 18, and $100 a month grows to about $42,100. If that’s out of reach for now, start with $10 or $25 and raise it as your budget allows. Cover an emergency cushion, your employer’s retirement match, and high-interest debt first.

How can new parents find money to save when the budget is already tight?

Start with changes that don’t require spending less. Update your Form W-4 for the Child Tax Credit, worth up to $2,200 per child for 2026, and use a dependent care FSA if you pay for child care and your employer offers one. Then review 30 days of statements for unused subscriptions, bank fees, and bills you can re-shop, like car insurance and your phone plan. Wasting less food, trimming takeout, and buying baby gear secondhand where it’s safe can free up more.

Should I pay off debt or save for my child first?

In most cases, pay off high-interest debt first. Credit card accounts that were charged interest paid an average rate of 22.15% in the second quarter of 2026, according to the Federal Reserve, far more than a hypothetical 7% investment return. You can still set up a small automatic contribution, such as $10 or $25 a month, to build the habit, and put free money like the $1,000 Trump Account deposit to work right away.

Can I use the Child Tax Credit to save for my child?

Yes. For 2026, the Child Tax Credit is worth up to $2,200 per qualifying child under age 17. When you claim it in Step 3 of your Form W-4, you receive it gradually through lower tax withholding, up to about $183 a month for one child, instead of all at once at tax time. An automatic transfer for part of that amount lets you save without your take-home pay feeling smaller. If you and your spouse both work, claim the credit on only one W-4.

Is $50 a month worth investing for a child?

Yes. At a hypothetical 7% average annual return, $50 a month invested from birth grows to about $21,000 by age 18, and about half of that is investment growth rather than your own contributions. Returns aren’t guaranteed and markets rise and fall along the way, but starting small and early gives compounding the most time to work.
