Loan College Cost Estimator
College is the largest future bill most families face, and it inflates faster than almost anything else they buy. Project the real future cost, credit the savings you already have, and get the monthly deposit that closes the gap — while there is still time for it to be small.
Today's all-in annual costs, roughly: $20,000–$25,000 in-state public, $45,000+ out-of-state, $60,000+ private — before aid. Long-run college cost inflation has averaged 3–6%; 5% is the conventional planning figure. Aid, scholarships and starting at a community college all cut the target — model them by lowering the annual cost.
Year by year, at enrollment prices
| Year | Cost that year |

Each college year is priced in that year's dollars — the second year costs more than the first because inflation keeps working while your student is enrolled.
How it works
Each future year is priced separately: cost in enrollment year k = today's annual cost × (1 + inflation)years until + k, and the total is their sum. Your existing savings are grown to enrollment day at the assumed return and subtracted to get the gap. The monthly deposit is the standard level-payment formula that accumulates exactly the gap by enrollment, at the same return, compounded monthly. Nothing here assumes aid — if you expect scholarships or grants, lower the annual cost input and watch the gap fall.
Formula & worked example
Formula: Each college year is inflated separately: year-k cost = today's annual cost × (1 + inflation)years until start + k. Total = the sum. Savings grow to enrollment at the assumed return; the gap is total minus grown savings; the monthly deposit is the level payment that accumulates the gap by enrollment, compounded monthly.
Worked example: Today's $28,000 a year, starting in 10 years at 5% inflation: year one costs $45,609 and the four years total $196,581. With $10,000 saved growing at 6% (to $17,908), the gap is $178,672 — closed by about $1,090 a month.
When to use this
- A child is born or starts school and the college bill needs a real number, not a vibe.
- Choosing a monthly 529 or savings contribution with the math shown.
- Comparing public vs private paths at future, like-for-like prices.
- Modelling what expected aid or a community-college start does to the gap.
How to use it, step by step
- Look up today's all-in annual cost for a realistic target school (or its net price).
- Set the years until enrollment from the child's age.
- Try inflation at 3%, 5% and 7% — see how much of the plan is that one number.
- Enter savings honestly; the grown value is credited against the total.
- Use the monthly deposit as the plan, and revisit yearly as aid and prices clarify.
What the inputs mean
| Input | What it is | Typical values |
|---|---|---|
| Today's annual cost | All-in: tuition, fees, room, board, books | $20–25k public in-state, $60k+ private |
| Years until enrollment | Time for inflation and saving to work | 0–18 |
| Inflation % | Annual college-cost growth | 3–6% long-run, 5% default |
| Savings & return | What exists and what it earns | 6% balanced-portfolio assumption |
Another worked example
A private-college path: today's cost $45,000 a year, a child 5 years out, inflation at 4%. The first year prices at $54,749 and four years total $232,491. With $25,000 already saved growing at 6% (to $33,456), the gap is $199,036 — and closing it in just 5 years takes about $2,853 a month, which is the arithmetic that makes an earlier start, a cheaper school, or expected aid part of the real plan.
Frequently asked questions
How much will 4 years of college cost in 10 years?
At today's $28,000 a year inflating at 5%: the first year alone costs $45,609 by enrollment, and the four years total $196,581. That gap between $112,000 (4 × today) and $196,581 is pure inflation — the reason college saving starts early.
How much should I save per month for college?
On the defaults — $10,000 already saved growing at 6% against a $196,581 target — the gap is $178,672 and the deposit that closes it is about $1,090 a month for 10 years. Start 5 years earlier and the same gap needs roughly a third of that per month; time is the cheapest input.
What inflation rate should I use for college costs?
College costs rose about 3–6% a year over recent decades, faster than general inflation. Use 5% as the planning default, then try 3% and 7% — the spread between them over 15+ years is the difference between a plan and a hope.
Does this assume a 529 plan?
No — it models savings generically, growing at your assumed return. A 529 adds tax advantages on qualified spending (and, for younger children, a Trump Account or other vehicles may sit alongside). The growth math the estimator does is the same either way; the tax wrapper is a separate optimisation.
What if we expect financial aid?
Model it directly: reduce the annual cost by the aid you reasonably expect (net-price calculators on each college's site give family-specific estimates). Every $5,000 off the annual figure removes roughly $32,000 from the 10-year-out total at 5% inflation.
🧒 A younger child in the picture too?
For children born 2025–2028, the Trump Accounts Calculator projects the new federal $1,000-seed account to age 18 — a head start that lands exactly when college starts.
Should I save for the full sticker price?
Most families should plan against a net price, not the sticker: use the college's official net-price calculator for a family-specific estimate, then run this estimator with that net annual figure. Planning for full price when aid is likely over-saves at the cost of retirement; planning for aid that doesn't arrive under-saves worse.
Is the monthly figure the same as a 529 contribution target?
It is the level monthly deposit that mathematically closes the gap at the assumed return — exactly what a 529 contribution plan does, minus the tax treatment. Whether markets deliver the assumed return is the risk every savings plan carries; the estimator shows the deposit the plan requires, not a guarantee.
