How to use this college savings calculator
Enter your child's current age and the age they'll start college (typically 18). Set the number of years in college (4 for a bachelor's degree, 2 for community college or associate's, up to 8 for extended programs). Enter the current annual cost of attendance at your target school and an expected annual cost increase (5% is a common assumption for US college costs).
Then enter your current savings balance, planned monthly contribution, and expected annual investment return. The calculator projects your savings balance at college start, compares it to the inflation-adjusted total cost, shows your funding percentage and any gap, and tells you the exact monthly contribution needed for 100% funding.
Why starting early matters so much
Time is the most powerful variable in this calculator. A family that starts saving $300/month when their child is born (with 7% returns) will have about $130,000 by age 18. The same family starting at age 10 would have only about $43,000 — needing nearly $900/month to reach the same target. That's the power of compound growth over 18 years vs 8 years.
Even small amounts matter when you start early. $100/month from birth at 7% returns grows to about $43,000 by age 18. That covers two years at many public universities. The key is consistency — automate contributions and let compounding do the heavy lifting.
Tax-advantaged education savings options
US — 529 Plans: Tax-free growth and withdrawals for qualified education expenses. State tax deductions in 30+ states. Can be used for K-12 tuition (up to $10,000/year) and apprenticeship programs. Unused funds can be rolled into a Roth IRA (up to $35,000 lifetime, subject to conditions).
US — Coverdell ESA: $2,000/year contribution limit. Tax-free for education expenses including K-12. Income limits apply. More flexible investment options than 529s but much lower contribution cap.
Canada — RESP: Registered Education Savings Plan with a 20% government match (Canada Education Savings Grant) up to $500/year per child. $50,000 lifetime contribution limit per beneficiary. Tax-deferred growth with taxation at the student's lower rate upon withdrawal.
UK — Junior ISA: £9,000/year tax-free savings for children under 18. Investment growth and withdrawals are completely tax-free. Can be used for any purpose at age 18, not restricted to education.
Frequently Asked Questions
How much does college actually cost?
In the US (2024–25), average published tuition and fees are about $11,600/year for in-state public universities, $23,600 for out-of-state public, and $43,400 for private non-profit institutions. Add room, board, books, and personal expenses, and total cost-of-attendance ranges from $23,000 to $60,000+/year. International tuition varies widely — UK universities charge £9,250/year for domestic students and £15,000–£40,000 for international students.
What is a 529 plan?
A 529 plan is a US tax-advantaged savings plan for education expenses. Contributions grow tax-free, and withdrawals for qualified education expenses (tuition, fees, room, board, books, computers) are also tax-free. Many states offer additional tax deductions for contributions. 529 plans can be used at any accredited institution nationwide and even some international schools. Similar tax-advantaged education savings accounts exist in Canada (RESP), UK (Junior ISA), and Australia (education savings).
What return rate should I use?
For a long time horizon (10+ years), a 7% average annual return is reasonable for a diversified stock portfolio (roughly matching S&P 500 historical returns after inflation adjustment). As college approaches, many families shift to more conservative investments — 4–5% for a blended portfolio. 529 plans often offer age-based portfolios that automatically become more conservative as the beneficiary gets older.
What inflation rate should I use for college costs?
College tuition has historically increased 3–6% annually in the US, generally outpacing general inflation. A 5% assumption is commonly used for planning purposes. If targeting a public in-state university, 3–4% may be more appropriate. Private institutions have recently moderated increases to 3–4%. International education costs vary — research your target country's trends.
What if I have multiple children?
Run this calculator separately for each child with their individual ages and target schools. A 529 plan can be transferred between siblings if one child doesn't need the full amount. Some families use a single 529 and change beneficiaries as each child enters college. The key is to start early for each child — even small monthly contributions compound significantly over 15–18 years.
Privacy and methodology
This calculator runs entirely in your browser — no personal or financial data is sent to any server. Future costs are projected using compound inflation on the current annual cost. Savings growth uses annual compounding with monthly contributions. The "needed monthly" calculation uses the future value of annuity formula. Results are estimates based on constant-rate assumptions. Actual returns, costs, and inflation will vary. This tool does not constitute financial advice.
