How the payment is worked out

Here is the formula in plain words. The payment equals the loan times the monthly rate over one minus a discount factor. The discount factor is one divided by one plus the monthly rate, multiplied out 48 times. With 6.5 percent a year the monthly rate is 0.5417 percent. The loan here is $40,000.
