Our free Mortgage Calculator estimates your monthly home loan payment including principal, interest, property taxes, homeowner's insurance, PMI, and HOA fees. Enter your home price, down payment, interest rate, and loan term to see a complete payment breakdown and amortization schedule.
Unlike simple loan calculators, this tool accounts for all the costs of homeownership, giving you a realistic picture of your total monthly housing expense. The amortization schedule shows how each payment is split between principal and interest over the life of your mortgage.
Mortgage Payment Formula Explained
The mortgage payment (principal and interest only) is calculated using:
M = P[r(1+r)n] / [(1+r)n − 1]
- M = Monthly mortgage payment
- P = Principal (loan amount after down payment)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (loan term in years × 12)
Your total monthly payment also includes property tax (annual ÷ 12), home insurance (annual ÷ 12), PMI if applicable, and HOA fees.

Mortgage Tips for Homebuyers
- Follow the 28/36 rule: Keep your mortgage payment under 28% of your gross monthly income, and total debt payments under 36%.
- Put 20% down: A 20% down payment eliminates the need for private mortgage insurance (PMI), saving you hundreds per month.
- Compare 15-year vs 30-year: A 15-year mortgage has higher payments but saves tens of thousands in interest.
- Shop multiple lenders: Interest rates can vary by 0.5% or more between lenders, making a big difference over 30 years.
- Consider extra payments: Even one extra payment per year can shave years off your mortgage and save thousands in interest.
