Many Canadian homeowners are surprised when they receive a mortgage renewal offer and see a higher payment than expected.
Your mortgage payment can increase at renewal for several reasons. The most common reason is a higher interest rate, but it is not the only factor. Your remaining balance, amortization period, payment frequency, and renewal choices also matter.
Higher Interest Rates
The biggest reason a payment may increase at renewal is that the new interest rate is higher than the rate on the previous term.
For example, if a homeowner had a mortgage rate near 2% during a previous term and renews at a rate closer to 5%, the payment may rise significantly, especially if the remaining balance is still large.
A higher interest rate means more of each payment goes toward interest. To keep the mortgage on schedule, the regular payment may need to increase.
Large Remaining Balance
The larger your remaining mortgage balance, the more sensitive your payment is to rate changes.
A 1% increase on a small balance may not change the payment dramatically. The same 1% increase on a large balance can create a much bigger payment change.
This is why two homeowners can receive the same renewal rate but experience very different payment increases.
Shorter Remaining Amortization
At renewal, your remaining amortization is usually shorter than when you first got the mortgage.
If you started with a 25-year amortization and completed a 5-year term, you may have around 20 years remaining. A shorter amortization means the balance must be paid off over less time.
This can increase the regular payment, especially when combined with a higher rate.
Payment Frequency Changes
Your payment frequency can also affect the amount you see on your renewal documents.
Monthly payments will look different from bi-weekly or accelerated bi-weekly payments. Accelerated payment options may result in more money paid each year, which can reduce the mortgage faster but may also feel like a higher cash-flow commitment.
Before comparing payments, make sure you are comparing the same payment frequency.
Changes to Mortgage Product or Term
Your payment may also change if you choose a different mortgage product, term length, or rate type.
For example:
- A fixed rate may have a different payment than a variable rate
- A shorter term may come with a different rate
- A new lender may calculate payments differently
- A change in amortization may affect the payment
Always review the full terms, not just the headline rate.
Can a Lump-Sum Payment Help?
A lump-sum prepayment may help reduce your payment pressure by lowering the principal balance before renewal.
If your lender allows a prepayment at renewal, paying down part of the mortgage may reduce the amount used to calculate your new payment.
However, using savings for a mortgage prepayment may not be right for everyone. You should consider your emergency fund, other debts, cash flow, and future plans.
What Can You Do Before Renewal?
If you are worried about a payment increase, consider these steps:
- Estimate your new payment early
- Compare several interest rate scenarios
- Ask your lender about available term options
- Check whether you can make a lump-sum prepayment
- Compare fixed and variable options
- Ask about extending or adjusting amortization if appropriate
- Speak with a mortgage broker or qualified professional
The earlier you start, the more options you may have.
Use a Renewal Calculator
A mortgage renewal calculator can help you estimate how your payment may change under different rates and assumptions.
Try testing scenarios such as:
- Current balance at 4.50%
- Current balance at 5.00%
- Current balance at 5.50%
- With and without a lump-sum payment
- Monthly vs accelerated bi-weekly payments
This can help you prepare before accepting a renewal offer.
Final Thoughts
Your mortgage payment may increase at renewal because your new rate, remaining balance, amortization, and payment frequency all affect the calculation.
A renewal offer should not be reviewed only by looking at the rate. You should also understand the payment, term, prepayment privileges, and total interest impact.
