Mortgage Calculator

Know Your Mortgage Payment

Based on the home's sale price, the term of the loan, buyer's down payment percentage, and the loan's interest rate, this calculator can help estimate what you'll need to pay out monthly for your new home. This calculator factors in PMI (Private Mortgage Insurance) for loans with less than a 20% down payment, as well as town property taxes and its effect on the total monthly mortgage payment.

What’s in the payment?

Principal and interest are calculated from the loan amount, rate, and term. Taxes, homeowners insurance, PMI, and HOA are added separately.

PITI + PMI + HOA

When does PMI apply?

This estimate includes PMI when the down payment is below 20%. Actual pricing and cancellation rules depend on the loan program and lender.

Loan amount × PMI rate ÷ 12

How is affordability read?

The housing ratio compares the payment to gross income. DTI adds other monthly debts. Lender thresholds vary by loan type and borrower profile.

Monthly debts ÷ gross income

70% rule

A quick acquisition screen, not a full underwriting model. It targets a purchase price at 70% of ARV after subtracting repairs.

MAO = ARV × 70% − rehab

All-in project cost

Purchase, rehab, buyer closing costs, lender points, simple interest, property carrying costs, and resale costs are all included.

Profit = ARV − all-in cost

Break-even price

The estimated resale price where proceeds after selling costs equal every other project cost. Taxes on profit are not included.

Pre-sale cost ÷ (1 − selling cost %)

Net operating income

Effective rental income after vacancy and recurring operating expenses, but before mortgage payments and income taxes.

NOI = effective income − operating expenses

Cash-on-cash return

Annual pre-tax cash flow compared with the down payment, buyer closing costs, and initial repairs invested in the property.

Annual cash flow ÷ cash invested

Debt service coverage

DSCR compares annual NOI with annual mortgage payments. A result above 1.00 means modeled NOI covers the modeled debt service.

DSCR = annual NOI ÷ annual debt service

Planning estimate only—not a loan quote, appraisal, tax opinion, or investment recommendation. Actual rates, rents, vacancy, taxes, insurance, PMI, closing costs, repair overruns, reserves, financing draws, and resale proceeds vary. Verify figures with qualified local professionals before committing funds.
