Savings Goal Calculator — How Much to Save Monthly

Formula

PMT = (F − P×(1+i)^n) × i / ((1+i)^n − 1) — F: goal, P: current savings, i: monthly rate, n: months

Frequently Asked Questions

What does the calculator return?

The fixed monthly deposit needed so that your current savings plus deposits plus interest reach the goal on time.

What if I already have enough?

If current savings alone will reach the goal, no monthly deposit is needed and the calculator says so.

Should I use a high return rate?

Use a conservative rate — savings accounts currently pay 3–5%; investment returns are not guaranteed.
