Enter today's annual college cost and how many years until enrollment. The calculator first acts as a college cost projector: it grows the cost at your tuition inflation rate for each year of attendance, since every year of the degree gets more expensive than the last. Separately, it grows your current savings and monthly contributions at your expected annual return. The difference between the projected cost and the projected savings is the funding gap, and the annuity formula solves for the extra monthly saving that closes it. These are planning estimates, not professional financial advice. Public vs private college costs differ sharply, so compare both before you set a target. A 529 plan is often the best way to save because growth is tax-free for qualified education costs, but check your own state's rules. Ask how much you should save each month for your child's college, and revisit the answer as your child enrolls and the start date gets closer.
College is a moving target: tuition rises most years, so you must save toward the price in the enrollment year, not today's sticker price. If college costs $28,000 a year today and tuition inflates at 5%, the first year 10 years from now costs $28,000 × 1.05¹⁰ = $45,609, and each later year of the degree costs more than the one before.
On the savings side, two forces work together: your current lump sum compounds at the investment return, and each monthly contribution compounds for its remaining months. The future value of the monthly stream is PMT × (((1 + r)ⁿ - 1) / r), with r the monthly return and n the number of months.
Subtract projected savings from projected cost and you get the funding gap. Dividing that gap by the same annuity factor gives the extra monthly saving that closes it exactly.
Pick your currency first. Enter today's full annual cost of your target college (tuition, fees, room, and board, not just tuition), the years until enrollment, and how many years the degree runs. Add your tuition inflation assumption, what you have saved already, your monthly contribution, and the annual return you expect.
The calculator shows the total projected cost, the first-year cost at enrollment, your projected savings split into contributions and investment growth, the savings gap, the percentage of the cost your savings cover, and the extra monthly amount that would close the gap. Use the results as your college savings planner: adjust any input to compare scenarios.
These are planning estimates, not professional financial advice: talk to a qualified advisor before making investment decisions.
College costs have historically risen about 4 to 6 percent a year, well above general consumer inflation near 2 to 3 percent. At 5 percent, today's cost roughly doubles in about 14 years; at 3 percent it takes about 24 years.
Using 5 percent is a reasonable default for planning. If you want a conservative plan, use a slightly higher rate: over-saving a little is cheaper than discovering a shortfall at enrollment.
A 529 college savings plan is the most popular dedicated vehicle: investments grow tax-free and withdrawals for qualified education expenses are tax-free, with many states adding a tax deduction for contributions. Age-based 529 portfolios automatically get more conservative as enrollment approaches.
Alternatives include Coverdell ESAs (capped at $2,000 a year), custodial UGMA/UTMA accounts (taxable, and they count heavily against financial aid), and plain taxable investment accounts (flexible but no education tax break). For a quick comparison, run the calculator once with a 529-style tax-free return and once with a lower taxable return to see the gap compounding creates.
A common rule of thumb is the one-third rule: save one-third of projected costs, borrow one-third, and pay one-third from income during the college years. For a newborn today, a few hundred dollars a month in a 529 often covers about one-third of expected in-state public university costs in 18 years.
You do not have to fund 100% of the cost. Scholarships, grants, financial aid, and the student's own earnings all shrink the target. Many families aim to cover half and treat the rest as a shared responsibility. Also keep perspective: fund your retirement first, because there are loans for college but none for retirement.
A 529 is flexible: you can change the beneficiary to another family member, including yourself, with no penalty. Recent rule changes also allow limited rollovers into the beneficiary's Roth IRA, subject to conditions.
Non-qualified withdrawals face income tax plus a 10 percent penalty on the earnings portion, which is why overfunding far beyond any plausible education use deserves a second thought. A financial advisor can walk through your state's specific rules.
Current annual cost $30,000, education inflation 5%, enrollment in 18 years, 4-year degree, starting from $0, $300 a month, 6% investment return.
First-year cost in 18 years: $30,000 × 1.05¹⁸ = $72,198.58. Four inflated years total about $311,184.89. The $300 monthly stream at 6% grows to about $116,205.96, covering roughly 37.34 percent of the projected total, with $64,800 of that from contributions and the rest from growth.
Closing the whole gap from birth would take about $503.36 a month on top. The honest takeaway: combine savings with aid, income during college, and sensible borrowing rather than treating the projection as a target you must hit exactly.
It depends on the college type, the years until enrollment, and how much of the cost you want to cover. As a rough guide, a few hundred dollars a month from birth in a 529 often covers about one-third of projected in-state public costs; private college needs substantially more. Enter your numbers above for a precise monthly figure.
Grow today's annual cost at your tuition inflation rate: cost × (1 + inflation)^years. At 5% inflation, a $30,000-a-year college costs about $72,199 per year in 18 years, and four years total about $311,185. The monthly figure assumes you start now and save steadily until your child enrolls.
College costs have historically risen 4 to 6 percent per year, faster than general inflation. Five percent is a reasonable default; use a slightly higher rate for a conservative plan.
A 529 college savings plan is the most popular choice: tax-free growth, tax-free withdrawals for qualified education expenses, and possible state tax deductions. Match the investment mix to your timeline, getting more conservative near enrollment.
For most families, yes, because of the tax treatment for education expenses. Alternatives like Coverdell ESAs, custodial accounts, and taxable accounts each have tradeoffs in contribution limits, taxes, or financial-aid impact.
You can change the beneficiary to another family member, and recent rules allow limited rollovers to the beneficiary's Roth IRA. Non-qualified withdrawals owe income tax plus a 10% penalty on earnings.
Yes. Fund your retirement at least to any employer match first: there are loans, grants, and aid for college, but no loans for retirement. An underfunded retirement helps no one, including your child.
Federal rules allow up to $10,000 per year per beneficiary for K-12 tuition, but state tax treatment varies and some states add penalties for K-12 use. Check your state's rules before withdrawing.
Recent averages for total cost of attendance run roughly $25,000 to $30,000 a year for public in-state universities, around $44,000 for public out-of-state, and about $58,000 to $60,000 for private colleges, with elite schools above $90,000. Always use your target school's published price for planning.
No. Most families combine savings with scholarships, grants, financial aid, student earnings, and some borrowing. Aiming to cover a share, often around half, beats an all-or-nothing plan you cannot sustain.
Aid is generally means-tested and institution-specific, so it shrinks the net price below the sticker price this calculator projects. 529 assets do count in aid formulas but far more favorably than custodial accounts in the student's name.
A blended 6 to 7 percent a year is reasonable for a newborn's 18-year timeline in a stock-heavy portfolio. Age-based portfolios shift toward bonds near enrollment, so expect 3 to 5 percent in the final years.
No. They are planning estimates based on the inflation and return assumptions you enter. Markets, tuition policy, and aid rules all change. Revisit the projection every year or two and adjust contributions as the picture sharpens. This calculator provides estimates, not professional financial advice.
