College Cost Calculator

About the College Cost Calculator

A college cost calculator projects the future price of a college education accounting for tuition inflation, estimates your 529 savings plan balance at enrollment, and calculates the monthly contribution needed to fully fund four years of higher education. College costs have risen at roughly 5-6% annually for decades — roughly double general inflation — meaning a $35,000/year college today costs approximately $57,000/year in 10 years. Without a concrete savings projection, most families dramatically underestimate what they will need. Our free college cost calculator works for US 529 savings plans, Canadian RESP accounts, UK Junior ISAs, and Australian education bonds. Enter the current annual college cost, years until your child enrolls, existing savings, monthly contribution, expected investment return, and tuition inflation rate to see the projected 4-year cost, your savings trajectory, and exactly how much extra you need to save monthly to close any gap. Early action makes an enormous difference: starting when a child is born versus age 10 requires approximately one-third the monthly contribution for the same result.

How It Works

Future 4-year college cost is calculated by inflating the current annual cost for each of the four years of attendance: Year 1 = Current cost × (1 + inflation)^years_until_enrollment; Year 2 = Current cost × (1 + inflation)^(years+1); and so on, summed for the total 4-year cost. 529 plan projected balance: Balance = Existing savings × (1 + monthly return)^months + Monthly contribution × [(1 + monthly return)^months - 1] / monthly return, where monthly return = annual return / 12. Gap = 4-year future cost - projected 529 balance. Additional monthly contribution needed = Gap × monthly rate / [(1 + monthly rate)^months - 1]. Example: $35,000/year current cost, 10 years to enrollment, $15,000 existing 529, $400/month contribution, 6% return, 5.5% tuition inflation. Year 1 future cost = $35,000 × (1.055)^10 = $59,512. 4-year total = approximately $253,000. Projected 529 at enrollment = $15,000 × (1.005)^120 + $400 × [(1.005)^120 - 1] / 0.005 = $27,231 + $65,551 = $92,782. Gap = $253,000 - $92,782 = $160,218. Additional monthly needed to close gap = approximately $710/month more.

Tips & Best Practices

• ✓Start a 529 plan the day your child is born — even if you can only contribute $50/month initially. A $50/month contribution from birth at 6% return grows to approximately $18,000 by age 18, and the tax-free growth compounds for 18 years.
• ✓Grandparents and family members can contribute to a 529 plan. Under 2025 rules, anyone can gift up to $18,000/year per beneficiary without gift tax implications — a $36,000 grandparent contribution in year 1 compounds to approximately $103,000 by high school graduation.
• ✓Superfunding a 529: you can front-load 5 years of contributions at once (5 × $18,000 = $90,000 per contributor) using the special 5-year gift tax election. A couple superfunding $180,000 when a child is born generates substantial tax-free growth over 18 years.
• ✓Choose aggressive growth allocation in 529 plans for children under 12 — you have time to ride market volatility. Most plans offer age-based portfolios that automatically shift from equities to bonds as enrollment approaches. Manually managed accounts can optimize this further.
• ✓In-state public universities offer the best value in the US: average 4-year in-state tuition ($45,000) versus out-of-state ($120,000+) or private ($170,000+). Factoring likely school type into your projection prevents over or under-saving.
• ✓529 plans can now be rolled over to a Roth IRA (up to $35,000 lifetime, after 15 years of account ownership). This removes the risk of over-saving: excess funds are not lost if your child receives scholarships or does not attend college.
• ✓The financial aid FAFSA calculation counts 529 assets at 5.64% for parent-owned accounts — meaning $100,000 in a 529 reduces aid eligibility by at most $5,640. This is far less impact than the same money in a student's name (20% assessment rate).
