College Savings Calculator
Monthly contribution needed to fund future college costs from current savings
Calculate required monthly savings for future college costs using inflation-adjusted tuition and investment growth projections.
What this tool does
This calculator estimates the monthly contribution needed to cover future college expenses, accounting for inflation and investment growth. It takes your current savings, the time until college begins, expected annual costs in today's money, how long college lasts, and your assumed investment return and inflation rate. The result shows both the required monthly deposit and any remaining funding gap. The calculation inflates college costs forward based on your inflation assumption, projects your existing savings at your chosen return rate, and determines what additional regular payments would close the shortfall. Results assume consistent monthly contributions and constant rates throughout the timeline. This is for illustration only and does not account for financial aid, scholarships, tax effects, or changes in actual costs or returns.

Why College Savings Need Inflation Adjustment
College costs historically rise faster than general inflation — often 3-5% annually while general inflation runs 2-3%. A college costing 25,000 today will likely cost 40,000-50,000 in 15 years. Savings target calculations must inflate current costs forward, or they systematically underfund the goal. The calculator applies user-specified inflation to bring today's cost numbers to their future-year equivalents before computing required savings.
Realistic College Cost Context
Community college annual cost: 5,000-15,000 including living costs. Public in-state 4-year: 15,000-35,000 annually including room and board. Public out-of-state: 35,000-60,000. Private university: 50,000-80,000+. Elite private: 80,000-90,000. These ranges include tuition, fees, room, board, books, and personal expenses. Financial aid can reduce cost significantly for qualifying families, but planning typically targets sticker price to ensure adequate funding if aid is limited.
Worked Example for New Parent
Years until college 15. Annual cost 25,000 today. Years of college 4. Current savings 0. Return 6%. Inflation 3%. Inflated annual cost 38,900. Total 4-year cost 155,700. Shortfall 155,700. Monthly contribution 535. A new parent funding entirely through monthly saving at 6% returns needs approximately 535 monthly for 15 years to fully fund college at today's inflation-adjusted 25,000 annual cost. Public options reduce the number. Starting earlier and/or private school targets dramatically change requirements.
What the Calculator Does Not Model
Financial aid — need-based and merit aid can cover substantial portions for many families. Scholarship opportunities. tax-advantaged education savings account plan tax advantages which make saving more effective. parent-held student loan loans and student loans which are additional funding sources. Grandparent contributions. State tuition assistance programs. The calculator shows the full-payment scenario; real family planning usually combines saving with aid, loans, and student contribution.
Patterns Commonly Observed in College Savings
Starting too late — saving for a 5-year-old's college is much harder than saving from birth. Underestimating inflation — using today's sticker price rather than future-adjusted numbers. Funding college before retirement — retirement cannot be financed through loans the way college can. Not using tax-advantaged education savings account or similar tax-advantaged accounts that boost effective returns. Planning only for in-state public when children may choose private options. The calculator makes the planning specific; the decision to over- or under-save should be deliberate.
College in 15 years years at $25,000 annual cost needs 535.72 monthly.

Sources & Methodology
Methodology
The calculator inflates today's annual college cost forward at the specified college inflation rate to determine the cost per year when college begins. This inflated annual cost is then multiplied by the number of college years to compute total future expenses. Current savings are projected forward at the investment return rate to establish their value at college start. The shortfall is calculated as total future college costs minus projected savings. The required monthly contribution is computed as an ordinary annuity payment using the shortfall amount, the investment return rate, and the number of months until college begins. The model assumes constant inflation and investment returns, treats contributions as made at month-end, and does not account for fees, taxes, market volatility, or changes in college costs beyond the specified inflation rate.
