Use the estimate as a starting point
This calculator estimates monthly principal and interest based on the price, down payment, interest rate, and loan term you enter. It does not calculate the complete cost of owning the home. A lender can prepare a property-specific estimate using your loan program and financial details.
Build the full monthly housing picture
- Property taxes: Use the actual parcel tax information when available. New construction, special taxes, and assessments can make a simple percentage estimate inaccurate.
- Homeowners insurance: Obtain a quote for the specific address and coverage. Availability, deductibles, exclusions, and premiums can vary significantly by property.
- Mortgage insurance: May apply depending on loan type, down payment, and lender requirements.
- HOA dues and special assessments: Confirm current dues, pending increases, transfer fees, and any special assessments.
- Utilities and maintenance: Budget for water, power, gas, trash, landscaping, pool care, and ongoing repairs.
- Closing costs and reserves: Plan for upfront costs and keep funds available after closing.
Compare loan offers thoughtfully
Ask lenders to quote the same loan amount, term, property-tax estimate, insurance assumptions, and rate-lock period. Compare interest rate, APR, points, lender fees, mortgage insurance, estimated cash to close, and whether the rate is locked. A lower payment can come with higher upfront costs or a longer repayment period.
Documents to review
For most covered mortgage applications, the lender provides a Loan Estimate early in the process and a Closing Disclosure before consummation. The CFPB explains how to compare the figures in its Loan Estimate guide and closing document checklist.
Calculator results are estimates of principal and interest only. They are not a loan offer, approval, quote, or guarantee. Actual payments and qualification depend on lender underwriting and property-specific costs.
