Savings Goal Calculator

Find how much to save each month to hit a target by a date. Enter the goal, current savings, timeframe, and expected return.

Monthly Savings Needed
To reach the goal.

Usage Tip

Automating the monthly transfer the day you are paid makes the goal far more likely — pay your savings first.

THE MATH
Needed from contributions = goal − current × (1+r)^n
Monthly = needed ÷ (((1+r)^n − 1) ÷ r)
r = monthly return, n = months
This finds the level monthly amount that, with your existing savings and expected return, reaches a target by a date.
A higher return or longer timeframe lowers the monthly amount needed.
Returns are not guaranteed; if they fall short you will need to save more or extend the timeframe.
For short-term goals, a low-risk account is safer even if the return is lower.
Inflation may raise the real cost of the goal over long horizons.
