The mortgage payment formula

This standard amortization formula calculates your fixed monthly mortgage payment.

M = P × [r(1+r)^n] / [(1+r)^n - 1]
M
Monthly payment
P
Principal loan amount
r
Monthly interest rate (annual / 12)
n
Total number of payments (years × 12)

Frequently asked questions about Mortgage Payoff Calculator

What is included in a mortgage payment?
A typical mortgage payment includes principal and interest. Property taxes, homeowners insurance, and PMI (if applicable) are often added as PITI but are not calculated here.
How does a shorter term affect my payment?
A shorter term increases your monthly payment but dramatically reduces the total interest paid over the life of the loan.
How is my monthly mortgage payment calculated?
Monthly payments are calculated using the loan amount, interest rate, and loan term based on a standard amortization formula.
What is an amortization schedule?
An amortization schedule shows every loan payment, including how much goes toward principal and interest over the life of the mortgage.
Can I pay off my mortgage early?
Yes. Making additional payments toward the principal can significantly reduce total interest and shorten the loan term.
What is mortgage principal?
Principal is the original amount borrowed before interest and other charges are added.
What is PMI?
Private Mortgage Insurance (PMI) is often required when your down payment is less than 20% of the home's purchase price.
How much down payment should I make?
A larger down payment reduces your loan amount, lowers monthly payments, and may eliminate PMI requirements.
Should I choose a 15-year or 30-year mortgage?
A 15-year mortgage usually has higher monthly payments but much lower total interest. A 30-year mortgage offers lower monthly payments but costs more overall.
What affects my mortgage interest rate?
Credit score, loan term, down payment, debt-to-income ratio, market conditions, and lender policies all influence mortgage rates.
Can refinancing lower my payment?
Refinancing may reduce your monthly payment if interest rates decrease or you extend your loan term.
Does this calculator include taxes and insurance?
No. This calculator estimates principal and interest payments only unless additional costs are entered separately.
