Mortgage Calculator

Estimate a monthly housing payment from home price, down payment, rate and term. Tax and insurance are optional amounts you enter — not escrow quotes.

Build your scenario

Use your actual figures where available. The output is an educational estimate based on the assumptions below.

Purchase price
Amount paid up front
Derived from price, or type a % to set the amount
Nominal annual rate
Repayment term
Optional. For an annual bill, divide by 12.
Optional homeowners insurance. Annual ÷ 12 is fine.

Tax and insurance in this total are the monthly amounts you entered. They are not an escrow quote from a lender or insurer. PMI, HOA fees, points and closing costs are not added.

Results are estimates for education. The large monthly total is P&I plus the tax and insurance figures you typed — not a lender escrow quote. Actual rates, PMI, points, HOA fees, compounding and underwriting can change the outcome. The schedule amortizes loan principal only (home price minus down payment).

How this mortgage calculator works

The loan principal is home price minus down payment. Monthly principal and interest use standard amortization on that principal. The large result then adds the monthly tax and insurance amounts you typed. Those extras are user estimates, not escrow quotes, and they are not part of the amortization table.

Important: Review the assumptions shown under each input. Changing one assumption can materially change the result.

When to use this calculator

  • Estimate a monthly housing payment that includes tax and insurance figures you already have (or annual amounts divided by 12).
  • See how a larger down payment shrinks the loan principal and the P&I portion.
  • Compare 15-year and 30-year terms on the same price and down payment — this is not a lender pre-approval.

Frequently asked questions

Are the tax and insurance figures official escrow amounts?

No. They are monthly amounts you type in (or annual figures you already divided by 12). They are not a lender or insurer quote.

What amount is amortized?

The loan principal is home price minus down payment. The schedule does not amortize tax or insurance.

Will this match a lender’s official quote?

Often not exactly. Quotes can add PMI, points, HOA fees, a different compounding convention, or escrow amounts that differ from the estimates you entered.
