Mortgage Payment Calculator

Most used

Estimate your full monthly housing payment — principal, interest, property tax and home insurance (PITI). Move the sliders to see how each variable affects your payment.

Home price $400,000
Down payment 20% · $80,000
Interest rate 6.5%
Loan term
Est. monthly payment (PITI)
$2,527
Principal & interest$2,023
Property tax (1.1%)$367
Home insurance$125
Loan amount$320,000
Total interest paid$408,000

How to use this calculator

  1. Home price — Enter the purchase price of the home you’re considering. If you’re just exploring, try the median US home price (~$420,000).
  2. Down payment — Conventional loans start at 3%, FHA at 3.5%. Putting 20%+ avoids PMI. Slide to see how each percentage affects your payment.
  3. Interest rate — Use current rates from a lender quote or check today’s averages. Even 0.5% makes a significant difference over 30 years.
  4. Loan term — 30-year loans have lower monthly payments but cost more in total interest. 15-year loans save tens of thousands but require higher payments.
  5. The result shows your estimated PITI — the four components that make up a full housing payment.
Principal
The portion of each payment that reduces the loan balance.
Interest
The cost of borrowing, charged monthly on the outstanding balance.
Property tax
Paid into escrow monthly; we estimate 1.1% of home value per year (varies by location).
Home insurance
Estimated at $1,500/yr — get actual quotes from 2–3 insurers.
PMI
Private Mortgage Insurance — required when your down payment is less than 20% on a conventional loan.
PITI
Principal + Interest + Taxes + Insurance — the full monthly housing cost.

Affordability Calculator

Find out how much home you can afford based on your income, debts, and down payment. Lenders typically limit your housing payment to 28% of gross income and total debts to 43% (debt-to-income ratio).

Gross monthly income $7,000
Monthly debts (car, student, etc.) $400
Down payment $60,000
Interest rate 6.5%
Est. home price you can afford
$340,000
Max monthly payment (28%)$1,960
Your DTI budget$3,010
Available for housing (DTI)$2,610
Limiting factorFront-end ratio

How to use this calculator

  1. Gross monthly income — Use your pre-tax income. For dual-income households, add both salaries together.
  2. Monthly debts — Include minimum payments on car loans, student loans, credit cards. Don’t include rent, utilities, or groceries.
  3. Down payment — The more you put down, the more expensive a home you can afford (and the lower your rate may be).
  4. The calculator uses two limits: the front-end ratio (28% of income for housing) and the back-end ratio (43% of income for all debts). The lower result is your real ceiling.
Front-end ratio
Your housing payment as a percentage of gross income. Most lenders cap this at 28%.
Back-end ratio (DTI)
All monthly debt payments divided by gross income. Lenders typically allow up to 43%.
Gross income
Your income before taxes and deductions — what lenders use for qualification.

Refinance Break-Even Calculator

Is refinancing worth it? Enter your current loan, the new terms, and closing costs to find how many months until the savings pay for themselves.

Current monthly payment $2,200
Remaining loan balance $320,000
New interest rate 5.75%
New loan term 30 yr
Closing costs $6,000
Break-even point
14 months
New monthly payment$1,868
Monthly savings$332
Closing costs$6,000
Refinancing makes sense if you stay >14 months.

How to use this calculator

  1. Current payment — Your existing principal and interest payment only (not taxes/insurance).
  2. Remaining balance — Check your last mortgage statement for the current payoff amount.
  3. New rate — Use a rate you’ve been quoted, or today’s published rates. Add 0.25–0.5% for a conservative estimate.
  4. Closing costs — Typically 2–5% of the loan amount. Ask your lender for a Loan Estimate to get the exact figure.
  5. If you plan to sell or move before the break-even point, refinancing probably isn’t worth it.
Break-even point
The number of months until your cumulative savings equal your closing costs.
Closing costs
Fees to originate the new loan — typically $3,000–$10,000. Can sometimes be rolled into the loan.
Cash-out refinance
Borrowing more than you owe to take equity as cash. Has different math — break-even is harder to calculate.
