What It Does

Lets you line up 2 to 4 refinance scenarios and see which one costs less over your actual hold period. Each option takes an interest rate, points, closing fees, and prepayment penalty structure (step-down from 5-year to none). The calculator totals points + fees + cumulative interest + any prepayment penalty at your chosen exit year, highlights the Best Option, and charts total cost over 10 years so you can see crossover points where a higher-rate/lower-fee loan beats a bought-down rate.

How to Use It

  1. Set your Loan Amount and Loan Term.
  2. Fill in at least two loan options: rate, points, closing fees, and prepay penalty window.
  3. Drag the Hold Period slider (0 to 10 years) to match how long you plan to hold the property.
  4. Read the red banner and the “Best Option” badge: that is the cheapest total cost of money at your hold period.
  5. Review the cost breakdown table (points, fees, interest paid, prepayment penalty, total) and the crossover callout.
  6. Scroll down to the line chart showing total cost trajectories.

  • Deciding whether buying down the rate makes sense for your planned hold.
  • Evaluating prepayment penalty risk before locking a 3 or 5 year penalty term.
