About this calculator
This calculator inflates today's annual college costs to the year enrollment begins and then adds up each year of attendance, with costs still rising while the student is enrolled. The formula is: Total Cost = (annualTuition + roomBoard) × (1 + r)^yearsUntilCollege × [(1 + r)^years − 1] / r, where r = inflationRate / 100 and years is the college duration. The term (1 + r)^yearsUntilCollege converts today's dollars into first-year dollars, and [(1 + r)^years − 1] / r sums the first year plus each later, more expensive year (it equals the number of years when inflation is 0). The result is the sticker price before financial aid; subtract the aid you expect for an out-of-pocket target. For reference, the College Board's Trends in College Pricing 2025 puts 2025-26 average published tuition and fees at $11,950 (public four-year, in-state), $31,880 (public out-of-state) and $45,000 (private nonprofit four-year), with room and board averaging $13,900 and $15,920. Published tuition rose 2.9% (public in-state) to 4.0% (private) in 2025-26, so 3-5% is a reasonable planning range for education inflation.
How to use
Suppose annual tuition and fees are $20,000, room and board $12,000, your child starts in 10 years, inflation is 5%, and college lasts 4 years. Step 1 — annual cost today: $20,000 + $12,000 = $32,000. Step 2 — first-year cost: $32,000 × 1.05^10 = $32,000 × 1.6289 ≈ $52,125. Step 3 — four years with costs still rising 5% a year: $52,125 × (1.05^4 − 1) / 0.05 = $52,125 × 4.3101 ≈ $224,665. With the default inputs ($47,000 a year today, 8 years away, 3.5% inflation, 4 years) the projection is about $260,862, or 1.39x today's four-year sticker price of $188,000.
Frequently asked questions
How much should I save per month to cover projected college costs in 10 years?
Once you have a total projected cost from this calculator, divide it by the number of months until enrollment to find the minimum monthly savings needed — but that ignores investment growth. If you invest in a 529 plan earning roughly 6% annually, you can save less per month and let compounding do part of the work. For example, to accumulate $225,000 in 10 years at 6% annual growth, you would need to contribute approximately $1,370 per month. Starting earlier dramatically reduces the required monthly contribution due to the power of compounding.
What financial aid should I expect when estimating net college costs?
Financial aid includes federal grants (like the Pell Grant, up to ~$7,395/year for eligible students), institutional merit or need-based scholarships, work-study income, and subsidized loans (which are costs, not aid, but reduce upfront cash needs). The average grant and scholarship aid received at 4-year public universities is roughly $8,000–$10,000 per year; at private non-profits it can exceed $20,000. Use the net price calculators available on individual college websites to get personalized estimates, then subtract the expected aid for all years from this calculator's projected total for a more precise savings target.
Why does college tuition inflation matter more than general inflation for savings planning?
College tuition has historically risen at roughly 4–8% per year — well above the general CPI inflation rate of 2–3%. This means the purchasing power of your savings erodes faster when the target is a college bill than when the target is, say, a grocery budget. Over 10 years, a 5% education inflation rate turns a $34,000 annual bill into a $55,400 bill — a 63% increase. Failing to account for this inflation gap is one of the most common mistakes in college savings plans, and it is why this calculator applies compound inflation specifically to education costs rather than using a general CPI assumption.
