How it works
Figure out how long it will take to reach a savings goal, or how much to save each month, in four steps.
Type the total amount you want to save, such as a $10,000 emergency fund or a $30,000 down payment.
Type the amount you have already accumulated toward this goal. Use 0 if you are starting fresh.
Type how much you can add to this goal each month. Be realistic - the result depends on this number.
Type the APY your savings account pays, if any. A high-yield savings account at 4-5% APY noticeably shortens the timeline.
The calculator shows how many months and years it will take to reach the goal, plus the total interest you will earn along the way.
