Savings Calculator
See how your savings grow with compound interest and regular monthly contributions — or flip on goal mode to find the monthly amount you need to reach a target by a certain date.
Turn a plan into a habit
A savings target is easy to calculate and hard to stick to. Savvu forecasts your real balances so you can see, month by month, whether your contribution actually fits alongside your bills — and adjust before you fall behind.

With compound interest you earn interest on your interest, not just on what you put in. This calculator compounds monthly: each month the balance grows by the monthly rate (annual rate ÷ 12), then your contribution is added. Over years, that compounding is what turns steady deposits into a much larger balance.
Future value (growth mode)
The ending balance is FV = P · (1 + i)N + PMT · ((1 + i)N − 1) / i, where P is your starting amount, PMT is the monthly contribution, i is the monthly rate, and N is the number of months.
Goal mode
Flip on goal mode and the calculator rearranges the same formula to solve for the monthly contribution needed to reach your target — after crediting the interest your starting balance will earn.
Tips
- A high-yield savings account or money-market rate is a realistic figure for the rate field.
- Increase the years to see how dramatically compounding accelerates later on.
- Small, consistent contributions usually beat waiting to save a large lump sum.
