What Is the College Savings (529) Calculator?

This calculator projects how much a 529 plan or other college savings account could grow to by the time your child starts college, based on your current balance, monthly contributions, and expected investment return.

Formula

Future Value = Current Savings × (1+r)ⁿ + Monthly Contribution × (((1+r)ⁿ − 1) ÷ r), where r is the monthly return and n is the number of months until college.

How to Use This Calculator

Worked Example

Starting with $5,000, contributing $200 a month for 15 years at a 6% annual return grows to roughly $70,400 — enough to cover a large share of a four-year public college budget.
