College Savings Calculator
Calculate the monthly contribution needed to reach a college cost target by enrollment, given your current savings and expected investment return.
About This Calculator
Find out how much you need to save each month to cover college costs by the time your child enrolls. Enter your target amount, current savings, years until enrollment, and expected annual return.
How It Works
Enter the total college cost you want to cover (tuition, fees, room and board), your current education savings, the years until enrollment, and an expected annual growth rate. The calculator uses the PMT (payment) formula to find the monthly contribution that grows your savings to the target by enrollment day. All inputs are user-supplied — no published college-cost data is assumed.
The Formula
PMT = (FV − PV × (1+r)^n) × r / ((1+r)^n − 1)
- FV
- Target college cost (future value needed)
- PV
- Current education savings (present value)
- r
- Monthly rate = annual rate ÷ 1200
- n
- Months until enrollment = years × 12
Frequently Asked Questions
- What college cost should I enter as the target?
- Use the total four-year estimated cost at enrollment — tuition, fees, room, board, and books. You can find current costs on the College Board's Trends in College Pricing report or the specific school's net price calculator, then adjust for expected annual tuition inflation (historically 3–5%).
- What annual return rate should I use?
- A 529 plan invested in an age-based equity portfolio has historically returned 5–8% annually before fees. A more conservative approach (bonds, CDs) might use 2–4%. Your actual return will depend on your investment choices and market conditions.
- Should I use this calculator for a 529 plan?
- Yes. The contribution math applies to any tax-advantaged or taxable savings account. The calculator computes the required monthly payment without assuming a specific account type or contribution limit — consult a financial advisor to confirm 529 limits and eligibility for your situation.
- What if I can only save a fixed amount per month?
- Enter your target cost and the years you have, then adjust the annual rate or initial savings until the required contribution matches your budget. Alternatively, save what you can and use student loans, grants, or scholarships to bridge any gap.
