College Funding Calculator
College costs keep rising, but a savings target only helps if you can see how it was built. This calculator takes the student’s age, today’s annual college cost, what you have already saved, expected scholarships, cost inflation, and investment return, then projects the cost at enrollment, grows your savings to the same date, subtracts scholarships, and gives the monthly savings that closes the remaining gap. Every intermediate figure is shown, so you can challenge any assumption instead of trusting a single number. Our retirement income calculator translates today’s contributions into future monthly income, helpful when deciding how much can safely go to college instead.
Planning estimate only. Actual college costs, aid, and investment returns will differ; this is not financial advice.
Quick Answer
The tool inflates today’s college cost to enrollment year, grows your savings at the investment return, subtracts scholarships, and reports the gap plus the monthly savings that closes it. An 8-year-old with a $26,000 yearly cost, $15,000 saved, $10,000 in scholarships, 4 percent inflation, and 6 percent return faces a $38,486.35 future cost against $26,862.72 of grown savings: a gap of about $1,624, closed by $9.91 per month. Note that this is one year of college at enrollment, not a four-year degree total.

Worked example, checked against this exact tool
Take an 8-year-old, today’s cost $26,000 a year, $15,000 saved, $10,000 of expected scholarships, 4 percent cost inflation, and 6 percent return. Years until college: 10. Future cost = 26,000 times 1.04 to the power of 10 = $38,486.35. Savings grown = 15,000 times 1.06 to the power of 10 = $26,862.72. Gap = 38,486.35 minus 10,000 minus 26,862.72 = $1,623.64, which needs $9.91 per month for 10 years at 6 percent, using the sinking-fund formula shown under the results. The reason the monthly figure looks so small is that the family has already covered 95.8 percent of the goal: grown savings plus scholarships total $36,862.72 against a $38,486.35 goal. Raise the inflation assumption to 6 percent and the future cost jumps to $46,562.04, the gap grows to $9,699.32, and the monthly need rises to $59.19, roughly six times higher. Inflation is the most sensitive number on the page, which is why the next sections spend time on getting the cost input right.
Two assumptions deserve to be stated plainly, because they change how you read the answer. First, scholarships are entered in enrollment-year dollars: the tool subtracts the figure you type directly from the projected goal, without inflating it. If your $10,000 is today’s scholarship value and awards rise with costs, you are understating aid; if the award is fixed in nominal dollars, the treatment is exact. Second, the return is a single flat rate for the whole period. Real portfolios do not grow in a straight line, and a bad sequence of returns near enrollment hurts more than the same average return spread evenly. Treat the monthly figure as a planning target to revisit, not a promise.
What the tool actually covers: one year, not four
This is the most important limitation on the page, and the live tool’s old wording did not make it prominent enough. The cost input is one year’s cost, and the answer is the savings needed for that one year at enrollment. A degree takes four years, and costs keep rising while the student is in college. Using the worked example at 4 percent inflation, the four successive years cost:
| College year | Annual cost |
|---|---|
| Year 1 (enrollment year) | $38,486.35 |
| Year 2 | $40,025.81 |
| Year 3 | $41,626.84 |
| Year 4 | $43,291.91 |
| Four-year total | $163,430.91 |
That total is about 4.2 times the single-year figure, not exactly four times, because each later year is inflated again. If your real goal is the full degree, do not stop at the tool’s monthly number: run the same logic against the four-year total, or set the funding goal to reflect that the tool’s answer covers year one and the rest must come from later savings, aid, work, or borrowing. Families who miss this distinction are the ones most likely to feel short in sophomore year. This page keeps the one-year tool because that is what the live tool computes, and states the boundary openly rather than quietly relabeling a one-year answer as a degree answer.
Start from real prices: sticker price versus net price
The cost input is only as good as the price you type. Published sticker prices and the net prices families actually pay after grants and aid are different numbers, and mixing them up is the most common planning error. According to the College Board’s Trends in College Pricing 2025 report, average published tuition and fees for 2025-26 are $11,950 for in-state students at public four-year colleges, $31,880 for out-of-state students at public four-year colleges, and $45,000 at private nonprofit four-year colleges. Total cost of attendance, which adds housing, food, books, transport, and personal costs, averages $30,990 for in-state public four-year students, $50,920 for out-of-state public four-year students, and $65,470 for private four-year students. Those are national averages: an individual college can sit far from the average, so use a specific school’s published cost when you have one, and the average only as a starting point.
The practical rule is to enter the figure that matches your situation. If you expect need-based aid, plan from net price after grants, because planning from sticker price overstates the target and can push the monthly figure so high that saving feels pointless. If you will pay full freight, plan from sticker price, because a net-price figure assumes aid you will not receive. The College Board’s own highlights show that grant aid now covers tuition and fees for full-time students at public two-year colleges, and that average net tuition at public four-year colleges has fallen in inflation-adjusted terms from its peak, which is why the sticker-versus-net choice matters more than a single percentage point of inflation. Whichever figure you choose, write down which one it is, so next year’s re-run compares like with like.
Which input moves the answer most
The worked example is nearly fully funded, so changing one input at a time barely moves its monthly figure, which would hide the real sensitivities. The table below therefore uses a second scenario with more room to move: an 8-year-old, $26,000 yearly cost, $5,000 saved, no scholarships, 4 percent inflation, 6 percent return, 100 percent goal. The base monthly need is $180.21. Each row changes one input only.
| Change (one input only) | Monthly savings needed | What it shows |
|---|---|---|
| Base case (age 8, 4 percent inflation, 6 percent return) | $180.21 | Starting point |
| Inflation 6 percent instead of 4 percent | $229.48 | A higher bill dominates |
| Inflation 3 percent instead of 4 percent | $158.58 | A lower bill helps less than starting early |
| Return 5 percent instead of 6 percent | $195.40 | Return matters, but modestly over 10 years |
| Return 7 percent instead of 6 percent | $165.53 | Chasing return is a weak lever |
| Start at age 13 instead of age 8 | $357.49 | Losing 5 years roughly doubles the monthly need |
| Start at age 3 instead of age 8 | $119.81 | Gaining 5 years cuts it by about a third |
| Funding goal 50 percent instead of 100 percent | $62.78 | A partial goal is a legitimate choice, not a failure |
The ranking is clear: time first, inflation second, return a distant third. That ordering should shape behavior. Starting five years earlier beats squeezing an extra percentage point of return, and it does so without extra risk. It also reframes the late-start problem: a family starting at age 13 is not behind because it picked the wrong investment, it is behind because compounding had half the time to work. The honest response to a late start is usually a partial funding goal plus a plan for the remainder (aid, student work, or borrowing), not a riskier portfolio pitched as a catch-up.
Scholarships and aid: subtract them before you set the target
Many college savings tools ask about scholarships late, or not at all, which inflates the savings target for families who will receive aid. This tool subtracts expected scholarships and grants from the funding goal before computing the gap, so aid directly reduces the monthly figure. Enter only aid you have a reasonable basis to expect, and revisit it: merit awards depend on grades and test results that change, and need-based aid depends on family finances and the college’s own policies. If aid falls through, the gap reappears in full, so it is worth running the tool once with scholarships and once without, and treating the difference as the amount at risk. Families with military benefits should check them separately: our GI Bill calculator estimates tuition and housing benefits that can be subtracted from the gap before setting a savings target.
Where to keep the money: the 529 question
The tool itself does not care where the money sits; its return input is the same either way. The account choice still matters, because tax treatment changes what that return is worth after tax. Under IRS rules for qualified tuition programs, distributions from a 529 plan are generally free of federal tax up to the beneficiary’s adjusted qualified education expenses, which include required tuition and fees, books, supplies, equipment, and room and board for students enrolled at least half time. The earnings portion of a nonqualified withdrawal is generally subject to income tax plus a 10 percent additional tax, with exceptions including scholarships, disability, and attendance at a military academy. That tax-free growth on qualified spending is the core advantage of a 529 over a taxable account, and it is why the return you type should be understood as a pre-tax return: the 529 advantage sits on top of the tool’s monthly figure, not inside it. State tax deductions vary by state and plan, so check your own state’s rules before assuming an extra benefit. To see how those contributions compound year by year, our 529 plan growth calculator projects the balance to enrollment day. Ownership also matters for financial aid, because how an account is reported on the FAFSA depends on who owns it; check the current FAFSA treatment for your situation rather than assuming every account is treated the same.
For money needed within a few years, the account question flips: the risk is no longer tax, it is timing. Savings earmarked for a student already in high school should not be exposed to the same market swings as savings for a newborn, because there is no time to recover from a fall. Age-based 529 portfolios handle this by shifting toward conservative investments as enrollment approaches, which is the right instinct even if you save elsewhere: shorten the horizon, shorten the risk. For money that must be available within a couple of years, a high-yield savings account is the usual parking place while the enrollment date approaches.
Saving for two (or more) kids
Run the tool once per child. Each child has a different horizon, a different starting balance, and possibly a different school price, so each gets a different monthly figure, and the household total is the sum. Fund the shortest horizon first in practice, because compounding has the least time to help there, and watch for overlapping enrollment years: two children in college at once doubles the annual draw in those years, which is when families lean hardest on scholarships, grants, and aid rather than savings alone. If the combined monthly total is unaffordable, the funding-goal picker is the release valve: setting 50 percent or 75 percent for a younger child, while keeping 100 percent for the oldest, is a common and defensible split, provided the family is explicit about how the remainder will be covered.
What competing calculators miss
The best-known college savings projectors do several things well: year-by-year tables, preset school prices, and goal-percentage scenarios, and this page matches the goal scenarios with its funding-goal picker. Where they fall short, and where this page is built to be better: most bury scholarships or leave them out entirely, so their monthly figures overstate what aided families must save; few show the formula with your own numbers, so the answer cannot be checked; and almost none state plainly that their headline figure covers one year rather than a degree, which quietly understates the full bill. This tool keeps scholarships as a front-page input, displays every intermediate figure plus the formula with your numbers, and pairs the one-year answer with the four-year table above, so the boundary of the answer is visible instead of hidden. The sensitivity table adds one more thing competitors rarely publish: which input actually moves the answer, so families spend their effort on starting earlier and pricing the school correctly rather than on chasing return.
Re-run the numbers every year
The monthly figure is a snapshot, not a contract. College inflation assumptions drift, returns vary, and the savings balance changes with every contribution. Re-running the tool once a year with the updated balance and remaining years keeps the target honest: in good market years the required monthly figure often falls, which is the reward for starting early, and in bad years it rises while there is still time to adjust. Keep a note of the inputs you used each year, especially whether the cost figure was sticker or net price, so the year-to-year change reflects reality rather than a changed definition.
Frequently asked questions
It depends on years left, cost inflation, and current savings. As a worked example, an 8-year-old with $15,000 saved and $10,000 of scholarships needs only about $10 per month to cover a $26,000 per year college growing at 4 percent, because compounding and existing savings do most of the work. With only $5,000 saved and no scholarships, the same child needs $180.21 per month. Run your own numbers rather than borrowing someone else’s rule of thumb.
Future cost equals today’s cost times (1 plus inflation) to the power of years until enrollment. At 4 percent inflation, $26,000 today becomes about $38,486 in 10 years.
Use 3 to 4 percent if you plan from net price after aid, and 5 to 6 percent if you plan from a private college sticker price. The inflation input moves the answer more than the return input, so test both ends of the range before committing to a monthly figure.
Yes. The tool subtracts expected scholarships and grants from the funding goal before computing the gap. Enter scholarships in enrollment-year dollars, and run the tool with and without them to see how much of your plan depends on aid arriving.
No. It covers one year of college at enrollment. A four-year degree costs more, because costs keep rising during college: in the worked example the four years total $163,430.91 against a first-year cost of $38,486.35. Use the four-year table in the article when planning for a full degree.
For most families, yes: qualified withdrawals are generally free of federal tax, which a taxable account cannot match. Check your state’s deduction rules too, and remember that the earnings portion of a nonqualified withdrawal is generally taxed plus a 10 percent additional tax, with exceptions including scholarships.
Monthly needs rise steeply: in the sensitivity table, starting at age 13 instead of age 8 roughly doubles the monthly figure for the same goal. The funding-goal picker lets you target 50 percent or 75 percent instead of 100 percent to keep the monthly number realistic, with a plan for the remainder.
Run it once per child with each child’s age and savings, then add the monthly figures together. Staggering goals (100 percent for the oldest, less for younger children) is a common approach when the combined total is unaffordable.
Use 5 to 6 percent to be conservative, and remember returns are never guaranteed. Over 10 years, moving the return from 6 percent to 7 percent changes the monthly figure far less than starting earlier or correcting the inflation assumption.
Retirement first. You can borrow for college but not for retirement, and most planners advise securing your own retirement savings before funding a child’s education.
With the sinking-fund formula: monthly equals gap times (r divided by 12) divided by ((1 plus r divided by 12) to the power of months minus 1), where r is the annual return and months is years until college times 12. If the return is zero, the monthly figure is simply the gap divided by months.
