Canadian-rule semi-annual compounding. The interest-rate solver uses bisection between 0% and 25% - it may report 25% if your payment is too small relative to the amount and term.

Calculators use general assumptions. Athena can review your numbers and explain lender rules, qualification questions or options the estimate may not cover.

What this calculator helps you explore

Any one unknown in the mortgage equation when you know the other three: the payment, the amount, the rate or the amortization.

What the estimate considers

  • The three values you supply
  • The payment frequency you choose
  • Canadian semi-annual compounding

What it may not capture

  • Whether a lender would approve the amount or rate you solved for
  • Fees, insurance premiums and closing costs
  • Qualification, which is a separate question from affordability

A practical example

If you know the payment you can live with, solve for the mortgage amount instead of guessing at a price, then check that amount against the qualification tools.

Assumptions and sources

  • Semi-annual compounding
  • The rate solver searches between 0% and 25% and reports the boundary if no solution exists
