Renewal letter decoder

Your bank just sent the renewal letter. Now decode it.

Enter the rate they offered, your balance, and your remaining amortisation. The calculator returns the dollar difference compared to current market rates and runs your offer through the eight-item completeness checklist most renewal letters quietly fail. The math is the Interest Act's semi-annual compounding formula. Nothing leaves the browser.

Your offer is 75 basis points above market. Late April 2026 broker-channel five-year fixed rates run roughly 4.04 to 4.29 per cent for strong credit. Your letter's 4.79 per cent is materially higher than what brokers are quoting on comparable files.

The 8-item offer-completeness checklist
Tick what's explicitly in your renewal letter. If your bank's offer doesn't say it, it doesn't exist. The checklist is RenewalRate.ca's framework for distinguishing a complete offer from a thin one at the same rate.
Tick the items in your offer letter.
A complete offer includes all 8 items. Most bank renewal letters include 2 to 4. The gap between a complete and incomplete offer is often the most expensive part of a renewal, dollar-for-dollar.

A complete offer at market rate is the goal.

Your bank quoted one rate with limited terms. A licensed Canadian mortgage brokerage can put the same file against thirty or more lenders and run the offer-completeness checklist against each one. Homewise is an Ontario-based FSRA-licensed brokerage that handles the comparison through a short online application. Free to the borrower; the brokerage is paid by the lender on funded files.

Methodology

Canadian fixed-rate mortgages compound twice a year by convention (Interest Act, RSC 1985, c. I-15, s. 6). Borrowers pay monthly. The calculator converts the offered annual rate to an effective monthly rate using ((1 + r/2)2/12) − 1, then runs a standard amortisation payment over the remaining years.

Market rate comparison uses 4.04 per cent as the late-April 2026 benchmark for broker-channel five-year fixed insured rates. Actual market rates fluctuate weekly and vary by lender, file quality, insured status, and amortisation. The benchmark is a reference point, not a quote.

Common questions

What's the offer-completeness checklist?

Eight features that should appear in any well-built renewal offer. Most bank renewal letters explicitly mention two to four. The remaining items are not necessarily absent from the underlying mortgage product, but if they aren't in the letter, you don't have a written commitment to them. The checklist is RenewalRate.ca's framework for normalising the comparison.

Is the offered rate negotiable?

Almost always. The renewal letter is an opening offer. Federally regulated lenders are required to provide renewal terms 21 days before maturity but are not required to lead with their best rate. Bringing a competing quote into the conversation typically moves the offer 10 to 30 basis points, sometimes more on larger balances.

Why does the collateral charge flag matter?

A collateral charge is registered against the property for an amount higher than the mortgage itself. TD, Tangerine, and several credit unions register them by default. Switching to another lender at renewal requires a full discharge and re-registration with legal fees of $500 to $1,000 plus typical lawyer costs, where a conventional charge can usually be transferred in for free. The letter should flag this.

What's a competitive five-year fixed rate right now?

As of late April 2026, broker-channel five-year fixed rates for strong credit profiles sit roughly in the 4.04 to 4.29 per cent range. Insured rates run lower than uninsured. Big-bank posted rates sit higher. Check Ratehub or a mortgage broker for rates tailored to your file.
