Direct answer

A lower renewal rate is not automatically the lower-cost offer after switching fees. Compare both offers on the same principal, remaining amortization and term, then inspect payment, interest, fees and end-of-term balance together.

Enter figures from current statements, declarations, illustrations or written offers. The result is an auditable scenario, not a quote, approval, recommendation or prediction.

How the calculation works

The calculator converts each Canadian nominal annual rate compounded semi-annually to an equivalent monthly rate, calculates a level payment across the remaining amortization, and measures interest plus entered fees during the selected comparison term.

The tool keeps rate, term, fees, limits, valuation and policy assumptions visible so a user can change one input at a time and explain why the result moved.

Worked reference example

With a 120,000 balance, ten years remaining and zero-percent offers, each payment is 1,000. A 600 switching fee makes the switch option 600 more expensive over five years even though the payments match.

The public fixture reproduces this boundary with deterministic arithmetic. Displayed money rounds to two decimals while the formula engine carries additional precision.

Inputs and documents to collect

Use the latest controlling document for each input. Record its date and whether the amount includes tax, fees, financing, deductibles, other recoveries or a non-guaranteed assumption.

  • Principal balance at renewal: Use the balance on the lender renewal statement.
  • Principal paid at renewal: Optional lump-sum principal payment made before comparing offers.
  • Remaining amortization: Years remaining after the renewal date.
  • Comparison term: Compare costs during the shorter entered term.
  • Current-lender renewal rate: Nominal annual rate compounded semi-annually.
  • Current-lender renewal fees: Verified fees paid because of this option.
  • Switch-lender rate: Nominal annual rate compounded semi-annually.
  • Switching and setup fees: Discharge, registration, appraisal, legal, administration and other verified switching costs.

How to interpret the result

Use the balance, rates, term, frequency and charges on written renewal offers. Confirm portability of mortgage insurance, collateral-charge costs, prepayment privileges and whether an appraisal or legal work is required.

Compare a base case with at least one adverse case. A smaller payment, lower rate or larger displayed value is not automatically the safer or lower-cost choice when scope, term, security, exclusions or guarantees differ.

Decision checklist

  • Verify every input against a dated document.
  • Keep the comparison horizon and scope consistent.
  • Separate cash paid now from amounts financed or retained.
  • Check a higher-cost or lower-benefit scenario.
  • Save the inputs and result date.
  • Ask the lender, insurer, adviser or regulator about policy-specific exceptions.

Audit the result before using it

Recalculate the reference case before relying on a personal scenario. Then compare each displayed output with a manual reasonableness check: a zero-rate loan should reduce to principal divided by periods, a percentage should reconcile to its numerator and denominator, a limit should never pay more than the entered eligible loss, and a guaranteed column must never absorb a non-guaranteed value. If the official document differs, keep the document as the controlling answer and investigate timing, compounding, rounding, fees, valuation, tax or policy wording.

Record the calculator URL, date, inputs, selected units and source document. That audit trail makes the estimate reproducible and gives a lender, insurer or adviser a precise discrepancy to review.

Limits and when to stop

The worksheet excludes approval, penalties before maturity, variable-rate changes, blended rates, cash-back clawbacks, provincial taxes, insurance eligibility and lender-specific daily-interest or rounding methods.

Stop and obtain qualified help when legal eligibility, tax treatment, underwriting, a live market rate, policy wording, official valuation or professional judgment controls the answer.

Common mistakes

  • Comparing different horizons or benefit scopes.
  • Treating an estimate as a binding quote or approval.
  • Leaving fees, deductibles, loan balances or non-guaranteed values out.
  • Using a market value where a lender or insurer valuation controls.
  • Assuming a lower payment always means a lower total cost.
  • Failing to retain the source document and calculation date.

Frequently asked questions

Does the lower rate always win?

No. Fees, amortization, prepayment terms and the balance remaining after the comparison term can change the result.

Does this guarantee I can switch?

No. The new lender must approve the application and may use different criteria.
