How Much to Save in 529 Plan? Calculator & Savings by Age
You don’t necessarily need to save enough to cover every dollar of college.
A 529 plan can help you build a tax-advantaged education fund, but the right savings goal depends on
- Where your child might attend college
- How much you can afford to contribute, and
- What portion of the bill you expect to cover.

How Much Does College Cost, and How Much Should You Cover?
You first need to estimate how much college might cost when your child enrolls.
Again, the amount you need to save will depend heavily on whether your child attends an in-state public college, an out-of-state public college, or a private university.
For a starting point, consider these approximate annual costs for the academic year, including tuition and room:
| College type | Approx. annual cost | Four-year cost at today’s prices |
|---|---|---|
| Public, in-state | $31,000 | $124,000 |
| Public, out-of-state | $50,900 | $203,600 |
| Private nonprofit | $65,500 | $262,000 |
These are illustrative estimates, not guarantees of what a particular college will charge. Actual costs vary by school, and books, fees, transportation, and personal expenses can increase the total.
How much of college should a 529 plan cover?
You don’t have to fund the entire projected bill through a 529 plan.
A common starting point is to aim for about 1/3 of total college costs and expect other sources to cover the remainder.
You may need to target higher if you want to give your child more flexibility or expect to have limited income available during college.
It may be lower if you’re balancing college savings against retirement contributions, an emergency fund, or other financial obligations.
How Much Should You Save in a 529 Plan Each Month?
Your monthly contribution should be based on the amount you want to have when your child starts college, not simply on what another family saves.
Suppose your goal is to accumulate $50,000 by the time your child turns 18. If you start when your child is born, you have considerably more time to invest than a parent who begins saving when the child is 10.
Your required contribution depends on:
- Your target balance: The more you want to accumulate, the more you’ll generally need to save.
- Your child’s age: Starting earlier gives your investments more time to compound.
- Your expected return: Higher returns can reduce the amount you need to contribute, but they are not guaranteed.
- Your existing balance: Money already invested can do part of the work for you.
Example: Saving for college from birth
Suppose you want to build a 529 balance of approximately $50,000 over 18 years and assume a 6% annual investment return.
If you start from zero and make regular monthly contributions, you would need to save roughly $115 per month, assuming the return is earned consistently and contributions are made at the end of each month.
This is an illustration, not a prediction. Actual investment returns fluctuate, and fees, contribution timing, and the timing of college withdrawals can change the result.
What if you can’t afford the recommended amount?
If you can’t hit the monthly target, start with what your budget can support.
A smaller contribution made consistently can still build a meaningful balance over time, particularly when you begin early.
You can
- Increase contributions when your income rises
- Add money from bonuses or gifts
- Redirect some of your savings as other expenses decline.
Many 529 plans allow you to change contribution amounts as your circumstances change.
How Much Should You Have Saved by Your Child’s Age?
There is no single 529 balance every family should have at each age.
Still, your child’s age can help you assess whether you’re on track.
| Child’s Age | Savings Focus | What to Do |
|---|---|---|
| 0–5 | Build a strong foundation | Open a 529, set a savings target, and contribute regularly, even small amounts. |
| 6–10 | Review your progress | Compare savings with your target. Increase contributions if possible. |
| 11–14 | Close the savings gap | Reassess college costs, consider larger contributions, and review your investments. |
| 15–17 | Prepare for college expenses | Estimate your shortfall and plan to cover it with income, financial aid, scholarships, or other savings. |
When your child is a newborn to age 5
You have more years for contributions and investment growth to accumulate before college begins.
Start by choosing a target based on the type of college you want to plan for and the portion of expenses you expect to pay. Then establish an affordable recurring contribution.
If you can’t save much at first, that’s not a reason to delay opening an account or abandon the goal.
You can always increase contributions as your financial situation improves.
When your child is ages 6 to 10
At this stage, you need to review your balance against your target.
Consider whether your assumptions about
- College costs
- Budget
- Your intended contribution level still makes sense.
If you’re behind, you may be able to increase monthly contributions or add occasional lump-sum deposits.
You can also revise your goal if fully funding your original target would put pressure on other financial priorities.
When your child is ages 11 to 14
With fewer years remaining, you have less time to build the account through contributions and investment growth.
This is also a good time to revisit your expected college choices and funding sources. You may have a clearer idea of whether in-state public colleges, out-of-state schools, or private universities are realistic possibilities.
When your child is ages 15 to 17
At this point, focus on the gap between your projected 529 balance and the expenses you expect to pay.
You may not have enough time to make up a large shortfall through investment growth alone.
- Estimate the first year’s costs
- Review your expected contributions, and
- Consider how you’ll pay expenses that the 529 won’t cover.
Simple Way to Check Your Progress
Rather than comparing your account with a generic age-based savings chart, you need to compare your actual balance with the target you calculated for your family.
Ask yourself three questions:
- How much do I expect college to cost when my child enrolls?
- What portion do I want my 529 plan to cover?
- Given my current balance and time remaining, how much do I need to contribute?
Then, revisit those answers at least once a year. Your savings target should change when your circumstances or expectations change.
How to Calculate Your 529 Plan Savings Goal
You can estimate your 529 savings goal in four steps: project college costs, decide how much you want to cover, account for your current savings, and calculate the monthly contribution needed to reach the target.
Step 1: Estimate the future cost of college
Start with an estimate of today’s annual college costs. Then project those costs forward using an assumed inflation rate.
For example, suppose a public in-state college currently costs approximately $24,000 per year for tuition and room. If you assume 4% annual inflation and your child starts college in 18 years, the first year’s cost would be approximately $48,000.
Each subsequent year may cost more.
You should therefore estimate each year separately rather than multiplying the first year’s projected cost by four.
Using these assumptions, the total for four years of college would be roughly $210,000 at the projected future prices.
Step 2: Decide what percentage you want to cover
Next, choose how much of that projected cost you want to fund through your 529 plan.
If your projected four-year cost is $210,000 and your goal is to cover one-third, your target would be approximately $70,000.
If you want to cover half, the target would be about $105,000. If you want to fund the full projected amount, your target would be higher still.
Step 3: Account for your existing savings and investment growth
If you already have money in a 529 plan, include that balance in your calculation.
Your existing savings may grow before college begins; that means it will reduce the amount you need to contribute from now on.
For example, suppose your goal is $70,000, your child has 10 years until college, and you already have $15,000 invested. You would calculate how much that $15,000 might grow over the next decade, then determine how much additional money you need to contribute.
Step 4: Calculate your required monthly contribution
Once you know your target, current balance, and time horizon, estimate the monthly amount needed to reach your goal.
Amount needed could be higher or lower depending on investment performance, fees, and contribution timing.
It can help to compare several scenarios:
| Planning Assumption | What to Test |
|---|---|
| College-cost inflation | 2%, 4%, and 6% |
| Investment return | 3%, 5%, and 8% |
| Savings period | Your child’s actual years until college |
| Share of college costs covered | One-third, one-half, or another realistic percentage |
How to Save Enough Without Overfunding a 529 Plan
Check your goal every year
Compare your 529 balance to the expected cost of college. Save more or less as needed.
Plan for extra money
If you have money left over, you can switch to another family member, pay for more school, or move up to $35,000 to a Roth IRA (rules apply).
Know the tax on withdrawals
If you take money out for non-school costs, you usually pay income tax plus a 10% federal penalty on the earnings.
Know the gift limits
You can give up to $19,000 per person without filing a gift tax return. A special rule lets you give five years at once, up to $95,000.
Check your state’s rules
Your state may give tax breaks for 529 savings. Check what counts as a school cost before you add or take out money.
Protect your retirement
Build an emergency fund, pay down debt, and save for retirement first. Then put more into the 529.
If you ask me, you don’t need to predict every detail of your child’s college future. You need a savings plan that gives you a realistic goal, room to adjust, and a way to make steady progress without sacrificing other financial priorities.
