How many months until you hit your target — with returns, and without.

It depends on three things: how much you have already saved, how much you add each month, and the return your money earns. This calculator grows your balance month by month — adding your contribution and compounding any return — until it reaches your goal, then reports the number of months.
More than most people expect, because the growth itself starts earning growth. The calculator shows the months needed with your expected return next to the months needed with no return at all, so you can see exactly how many months the return saves you.
Work backwards: subtract your current savings from the goal, then divide by the number of months until your deadline. That is the monthly amount you need with no return at all. Any return your money earns means you can get there with a little less each month.
