Toolstia / savings goal calculator
Savings goal calculator
Set a target, say how much you have already saved and the interest rate, and find either the monthly deposit you need or the time it will take at a deposit you choose.
Interest is added monthly and deposits are made at the end of each month. Real accounts and rates vary, and interest may be taxable.
How it works
- Pick monthly deposit or time to goal.
- Enter your goal, current savings and interest rate.
- Read the result, with total deposits and interest earned.
Monthly deposit mode
Enter how many years you have. The calculator finds the deposit that grows your savings to the goal, with interest added monthly.
Time mode
Enter a deposit you can afford and the calculator counts the months until you reach the goal.
Interest
Interest is added each month at the yearly rate divided by twelve, and deposits are made at the end of each month.
Already saved
Money you already have keeps earning interest, so it lowers the deposit you need.
Questions
Does it include tax or inflation?
No. Real accounts, tax and inflation change the result, so treat it as an estimate.
What if I have no interest?
Leave the rate at 0 and the deposit is simply the remaining amount divided by the months.
