Calculate Monthly Mortgage (PITI)

Enter home price, down payment, rate, term, and monthly escrow items. Add extra payment to see interest savings and earlier payoff impact.

$450K
This tool assumes a standard fixed-rate mortgage. If your loan has adjustable rates, the real payment can change over time.
20.0%
$90K
Down payment can be entered as % or amount. The calculator keeps them consistent with the home price.
6.75%
Enter the nominal annual rate (APR-like). The monthly payment uses the standard fixed-rate amortization formula.
30Y
Common terms are 15 and 30 years. Longer terms generally lower the payment but increase total interest.
These amounts are added to your monthly payment estimate to show a realistic "PITI" style total. (PMI/MIP depends on loan type and down payment.)
$0
Extra payments reduce principal faster, which typically reduces total interest and shortens payoff time.

Amortization Schedule (Monthly)

Schedule shows principal/interest split month-by-month. Taxes/insurance/HOA/MI are not amortized (they're added to the PITI estimate).

Smart Tips

Taxes and insurance can move over time. Re-check your PITI estimate whenever your escrow amounts change.
A shorter term often increases the monthly payment but can reduce total interest significantly.
Extra monthly principal typically has the biggest impact early in the loan because interest is calculated on the remaining balance.
Compare "Monthly P&I" vs "Monthly PITI" to avoid underestimating your real cash outflow.
If you're near a down-payment threshold, improving down payment may reduce or eliminate mortgage insurance.

Understanding Mortgage Calculation

What is a Mortgage?

A mortgage is a loan used to purchase real estate where the property serves as collateral. Most common fixed-rate mortgages use equal monthly payments for principal and interest, with the principal share growing over time.

What is PITI?

PITI is a practical monthly housing payment estimate that includes Principal and Interest (the loan payment), plus Taxes and Insurance. Many homeowners also pay HOA dues and sometimes Mortgage Insurance—this tool includes those as well to avoid underestimating monthly cost.

How is the Mortgage Payment Calculated?

For a fixed-rate loan, the monthly Principal & Interest payment is computed using the amortization formula:

P&I = L × r × (1 + r)n / ((1 + r)n − 1)

where L is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments (years × 12).

Monthly PITI is then: PITI = P&I + Taxes + Insurance + HOA + Mortgage Insurance.

Factors Affecting Your Mortgage Payment

Uses & Benefits

Budgeting with realistic monthly cost

PITI helps you estimate the true monthly outflow instead of focusing on principal and interest only.

Interest and payoff planning

The amortization schedule shows where your money goes each month and how extra payments change interest.

Scenario comparisons

Compare different down payments, rates, and terms to understand tradeoffs before you commit.

Better risk awareness

Seeing PITI plus optional items (HOA/MI) reduces the chance of payment shock after purchase.

Frequently Asked Questions

Why is PITI higher than my lender's quoted payment?
Some quotes show only principal & interest. PITI includes escrowed items like property taxes and insurance; HOA and mortgage insurance can also add to your monthly outflow.
Does this include closing costs or upfront fees?
No. This tool models monthly payments and amortization. Closing costs are typically paid upfront (or rolled into the loan in some cases) and vary widely by region and lender.
How accurate is the amortization schedule with extra payments?
It is accurate for a fixed-rate loan when extra payments are applied to principal monthly. Real lenders may apply extra payments on the date received and may have specific rules for curtailments and escrow.
Does changing currency convert my values?
No. Currency selection changes the symbol and number formatting only. Enter values in the currency you're planning with.
What happens if I enter 0% interest?
With 0% interest, the monthly principal payment is loan amount divided by months. The calculator handles this edge case explicitly.
