Mortgage Payment Calculator
Mortgage Payment Formula
A mortgage payment calculator uses a standard loan amortization formula to determine monthly mortgage payments. Mortgage lenders, banks, credit unions, and home financing companies use this calculation worldwide.
Mortgage Formula
M = P × R × (1 + R)^N ÷ ((1 + R)^N − 1)
- M = Monthly Mortgage Payment
- P = Loan Amount
- R = Monthly Interest Rate
- N = Total Number of Monthly Payments
This formula is used in mortgage payment calculators, home loan calculators, refinance calculators, remortgage calculators, and second mortgage calculators throughout the United States, Canada, the United Kingdom, Australia, and many other countries.
