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”)
