      How these calculations work

      Monthly payment

      Standard amortization formula: M = P × [r(1+r)ⁿ] / [(1+r)ⁿ−1], where P = principal, r = monthly rate, n = total months.

      APR

      Calculated APR is estimated by finding the monthly rate where the present value of all payments equals the loan amount minus upfront fees. Lender APR may differ due to fees not included here (title, escrow, prepaid interest). A gap over 0.15% is flagged.

      True loan cost

      Total interest paid over the loan life, plus all upfront fees (closing costs + points) and total PMI paid.

      Points breakeven

      Upfront points cost divided by monthly payment savings versus a no-points alternative.

      Assumptions

      • Fixed-rate loan throughout the term
      • No prepayments
      • PMI cancels at the month you specify
      • Closing costs are paid upfront, not rolled in
      • Taxes and homeowners insurance are not included unless you add them as entered costs

      Frequently asked questions

      What is the best way to compare mortgage offers?

      Compare APR (not just interest rate), total interest paid over your expected holding period, and closing costs. A lower rate with high points may cost more than a higher rate with no points if you sell within 5 years.

      What is the difference between interest rate and APR?

      The interest rate is the base cost of borrowing. APR includes the interest rate plus fees and points, giving you a true cost comparison across loans.

      Should I pay points to get a lower mortgage rate?

      It depends on how long you keep the loan. Use the break-even calculator: divide the upfront cost of points by your monthly savings. If you'll stay longer than the break-even period, points save money.

      How many mortgage quotes should I get?

      Studies show that getting 3–5 quotes saves the average borrower $1,500–$3,000 over the life of the loan. Lenders know you are shopping, and multiple hard inquiries within a 14–45 day window count as a single inquiry on your credit report.

      What fees should I compare beyond the interest rate?

      Compare origination fees, discount points, appraisal, title insurance, and prepaid items (escrow setup). The Loan Estimate form standardizes disclosure — request one from each lender and compare Section A and Section B fees line by line.

      What is a lock period and why does it matter?

      A rate lock guarantees your interest rate for a set period (usually 30–60 days) while your loan closes. Shorter locks cost less but carry risk if closing is delayed. Longer locks add cost but protect against rate increases.

      How this calculator works

      APR is calculated by solving for the discount rate that equates the present value of all payments (including fees and points) to the loan amount. Total cost comparisons use the actual amortization schedule over each time horizon. Points break-even divides the upfront cost by the monthly payment savings.
