How It Works
The savings goal calculator solves for time using the future value of a series formula in reverse. Given your goal amount, current balance, monthly contribution, and interest rate, it calculates exactly how many months it will take to reach your target.
The formula used is: months = log(1 + (needed × r / PMT)) / log(1 + r), where r is the monthly interest rate and PMT is your monthly contribution.
Adjust the monthly contribution slider to see how saving more each month dramatically shortens your timeline.
