The PMT function returns the payment amount needed for borrowing a fixed sum of money based on constant payments and interest rate.
You can also use the PMT function to calculate the amount to save each period to reach a given sum, based on an interest rate and the number of periods.
The above image shows the annual payment needed for a 10-year 12 000 loan based on 5 percent interest rate.
