Fixed vs variable calculator

Compare fixed, variable and adjustable mortgages when rates fall, stay flat or rise. See payments and total interest over the term.

Updated October 7, 2026

How is it calculated?

We hold the fixed rate constant and move prime along your chosen path over five years, then total the interest.

What should I do with the result?

Use it to set a budget or a target rate, then let lenders bid on your actual mortgage. Bids include rate, penalty method, prepayment and fees, so you can compare the full cost.
