Quick answer

A mortgage calculator estimates monthly payment from loan amount, interest rate, loan term, and common housing costs such as property tax and insurance.

Use it to compare home prices, down payments, 15-year vs 30-year terms, extra principal payment scenarios, and yearly amortization before requesting lender quotes.

Best inputs

Loan basics

Home price, down payment, interest rate, and loan term drive the principal and interest payment.

Housing costs

Property tax, homeowners insurance, HOA, and extra principal can change the monthly total materially.

How the mortgage calculator works
Fixed-rate principal and interest are calculated first, then common monthly housing costs are added.

M = P x r(1+r)^n / ((1+r)^n - 1)

P is loan amount, r is monthly interest rate, and n is the number of monthly payments. Taxes, insurance, HOA, and extra principal are added after principal and interest.

Example: A $450,000 home with $90,000 down leaves a $360,000 loan. At 6.5% for 30 years, principal and interest are estimated before property tax, insurance, HOA, and extra principal.

Estimate, not a quote

Mortgage costs vary by lender, credit profile, location, taxes, insurance, and closing costs. This page uses U.S.-style property tax, homeowners insurance, HOA, and escrow-style planning assumptions for rough scenario comparison before requesting real loan estimates.

Calculations are handled in the browser for this tool based on the current public implementation. Avoid entering sensitive personal financial details unless you have reviewed the implementation.

Common use cases
Mortgage estimates are most useful when comparing several assumptions side by side.

Monthly payment planning

Estimate principal, interest, taxes, insurance, and HOA before deciding a target purchase price.

15-year vs 30-year comparison

Change the loan term to see how monthly payment and total interest shift.

Extra principal scenarios

Add extra monthly principal to estimate faster payoff timing and lower interest cost.

Amortization review

Use the yearly schedule and CSV export to see how principal, interest, and ending balance change over time.

Search scenarios this tool matches

Common mistakes to avoid
These checks help prevent bad outputs, failed exports, and confusing results.

Treating the estimate as a quote

Rates, PMI, lender fees, credits, escrow rules, and closing costs can change real offers. Use this for planning before lender quotes.

Leaving tax or insurance blank

Principal and interest alone can understate the monthly cost. Add realistic property tax, insurance, HOA, and local assessments when possible.

Comparing terms by payment only

A lower monthly payment can mean much higher total interest. Compare total interest and payoff timing as well as monthly cost.

Example, assumptions, and limitations
Mortgage estimates are useful for scenario planning before comparing lender quotes.

Example

A $400,000 loan at 6.5% for 30 years estimates principal and interest before adding U.S.-style property tax, insurance, HOA, or extra principal.

Assumption

The core payment formula assumes a fixed-rate loan with equal monthly payments over the selected term.

Limitation

PMI, closing costs, escrow adjustments, lender credits, tax changes, and local assessments are not included.

Frequently asked questions
What is a mortgage calculator with taxes and insurance?

It estimates monthly payment from loan amount, interest rate, term, property tax, homeowners insurance, HOA dues, and optional extra principal payments.

What is included in monthly payment?

The total shown here includes principal and interest, estimated property tax, insurance, HOA, and extra principal payment if entered.

How do extra payments affect the mortgage?

Extra principal payments reduce the balance faster, which can shorten payoff time and reduce total interest.

Why is my real payment different?

Real payments can include PMI, escrow changes, local taxes, lender fees, and insurance changes that this simple estimate does not model.

Can I use this for a 15-year mortgage?

Yes. Change the loan term to 15 years or any term between 1 and 50 years.

Is this mortgage estimate financial advice?

No. It is an educational estimate for scenario planning, not a lender quote, underwriting decision, or financial advice.
