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 180 times. With 5.5 percent a year the monthly rate is 0.4583 percent. The loan here is $400,000.
