How It Works

The same amortization formula used for any fixed-rate loan applies to a mortgage: principal and interest are spread evenly across the loan term.

Formula

Monthly Payment = P × r × (1 + r)^n / ((1 + r)^n − 1), where P is the mortgage principal, r is the monthly interest rate, and n is the number of monthly payments.

Example

A 300,000 mortgage at 6.5% over 360 months (30 years) has a monthly principal-and-interest payment of roughly 1,896.

Frequently Asked Questions

Does this include property tax and insurance?
No, this calculates principal and interest only. Your actual monthly mortgage payment is often higher once property tax, homeowners insurance and any mortgage insurance are included.
