How this calculator works

Estimate a U.S. mortgage payment including principal, interest, property tax, homeowners insurance and HOA dues. It uses the values you enter and shows the main components separately so you can review the estimate rather than relying on one unexplained number.

Formula

Monthly principal and interest = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1]
Example

For a $400,000 home with $80,000 down, the financed principal is $320,000. Taxes, insurance and HOA are then added to principal and interest.

How to improve the estimate

  • Use a current lender quote rather than an advertised headline rate.
  • Enter local property tax and insurance estimates; both vary widely.
  • Mortgage insurance, closing costs and changing escrow payments are not automatically included.

Understanding the result

The result is for comparison and planning. Actual bills, lender calculations, taxes, fees, employment rules or contract terms may differ. Verify important decisions with the relevant provider, lender, employer, tax authority or other authoritative source.

Frequently asked questions

Does this include property tax?

Yes. Annual property tax is divided by 12 and included in the displayed housing payment.

Does the calculator include PMI?

No. Add estimated monthly mortgage insurance to the HOA field for a rough combined payment.

Is this a loan approval estimate?

No. Lenders also consider credit, income, debts, reserves, property details and program rules.
