Rates move daily. See exactly what each increment is worth on your loan amount, in monthly payment and in total interest, so you know how much a rate change actually matters to you.
Your loan
For reference, the Freddie Mac survey average for a 30-year fixed loan was 6.69% as of 2026-08-06. That is an average, not a quote for your loan.

What this says
On a $540,000 loan over 30 years, a rate one point lower would change your payment by −$347 and a rate one point higher by +$363.
Taxes, insurance, HOA dues and mortgage insurance do not move with the rate, so the total payment changes less in percentage terms than principal and interest does. If rates fall after you close, refinancing is how you capture the difference — with closing costs and a term reset to weigh.
Assumptions behind these numbers
- Property taxes, homeowners insurance, HOA dues and maintenance are estimates you can change; actual amounts vary by property and municipality.
- Home appreciation, rent growth and investment returns are assumptions, not predictions. Real markets move up and down.
- Mortgage insurance figures are estimates. Actual pricing depends on the lender, the mortgage insurer and your credit profile.
- Results ignore income tax effects, such as any deduction for mortgage interest or property taxes.
- Interest rates shown are averages or your own entries, not a rate quote or lock.
