Future value of monthly savings

Enter values to calculate.

How it works

We use the future value of an annuity: FV = Pmt × [(1+r)^n − 1] / r, where Pmt is the monthly deposit, r is the monthly rate, and n is the number of months. Assumes constant monthly deposit and rate.

When to use it

Use it to set a savings target, to see the impact of increasing contributions, or to compare different return assumptions.

Frequently asked questions

What return rate should I use?

Historical long-term stock returns are often cited around 7–10%; use a conservative rate for planning.
