How the payment and schedule are calculated

The level payment that exactly clears a loan over its term:

payment = P × [ r(1 + r)n ] / [ (1 + r)n − 1 ]

where r is the rate per month and n the number of months.

Worked example. $200,000 at 6% over 30 years: r = 0.005, n = 360, giving $1,199.10 a month.

Each month, interest is charged on the balance outstanding and the rest of the payment reduces the balance. Early on almost all of it is interest; the totals here are summed from the schedule, so they match what the table adds up to rather than being payment × months.
