Amortization Tester

Creating detailed mortgage scenarios requires a powerful mortgage calculator. RateSpy’s advanced amortization tester is built on Microsoft Excel for maximum flexibility.

This tool lets you:

  • compare two different mortgages side by side
  • compare multiple terms (e.g., compare a 5-year variable with a 2-year fixed that renews into a 3-year fixed)
  • make any rate assumptions you can imagine
  • calculate different pre-payment scenarios
  • make each mortgage’s payments equal (to eliminate concerns about “opportunity cost”)
