Set your target, how long you have, and the return you expect — and see exactly how much to put aside each month to get there on time.
Reaching a savings target is really a small planning puzzle with three moving parts: the gap between where you are and where you want to be, the time you have, and the growth your money earns along the way. Fix any two and the third falls out. This tool fixes your goal and timeline, then solves for the monthly deposit.
Under the hood it does two things. First it grows what you already have forward to the target date at your expected return. Whatever gap remains is what your monthly deposits must cover — and those deposits earn returns too, so we solve the standard future value of an annuity formula for the payment that lands you exactly on target.
How much should I save each month to reach my goal?
It depends on the gap above your current savings, the number of months you have, and your expected return. The calculator solves for the exact monthly deposit after growing your current balance forward.
What return should I assume?
For short goals, keep it low — 0 to 2% in cash or high-yield savings. For long-term invested goals, 4 to 7% is a common planning assumption, though real returns vary.
What if I am already on track?
If your current savings alone will reach the goal by the target date, the required monthly deposit shows as zero. You can still contribute to build a cushion or finish sooner.
