How RBC Mortgage Rates Really Work: Posted vs. Discounted

What Determines RBC Mortgage Rates

RBC, like other major lenders, sets its mortgage rates by weighing a number of factors. According to an official RBC news release, the bank considers its funding costs and market conditions when making changes to residential mortgage rates.

Funding costs are particularly important. As the Bank of Canada explains, a lender's cost of funds—driven by interest rates on deposits and investments in Canada and abroad—is the most significant factor in setting mortgage rates. These costs move with economic growth and global conditions, so when global markets shift, RBC adjusts its rates accordingly.

Another key influence is the Bank of Canada's policy interest rate. When the central bank changes its rate, banks typically adjust their prime rates, which are the basis for variable-rate mortgages. For example, RBC's prime rate was 4.45% as of October 30, 2025.

Borrower-specific factors also play a role. Your credit history, credit score, down payment amount, and whether your mortgage is insured all affect the rate you are offered. A strong credit profile and mortgage default insurance can lower your rate, as the insurer protects the lender from default risk.

• Funding costs and market conditions drive RBC's rate changes.
• The Bank of Canada's policy rate influences prime rate, which affects variable-rate pricing.
• Borrower risk factors, like credit score and down payment, can also change the rate you qualify for.

Posted Rates vs. Discounted Rates

RBC displays two sets of rates: posted rates and special, discounted rates. Posted rates are the official rates published on RBC's website and are used for calculating mortgage break penalties. Special rates, on the other hand, are offers that are often lower than posted rates, but they are not the official posted rates.

For example, as of August 2026, NerdWallet reported a 5-year fixed uninsured special rate of 4.89%, compared to a posted rate of 6.09%. The gap between posted and discounted rates can be significant, so it's important to know what you're actually being quoted.

RBC notes that special offers may be changed, withdrawn, or extended at any time without notice. That means the rate you see advertised today might not be available tomorrow, and your final rate will depend on your application and negotiation.

• Posted rates are used for penalty calculations and are generally higher.
• Special discounted rates are what most borrowers actually pay.
• Special offers are subject to change at any time.

How to Get a Discounted Rate

RBC's mortgage rates are negotiable. Well-qualified borrowers can often obtain discounts off the posted rates. To improve your chances, focus on strengthening your credit score, increasing your down payment, and demonstrating a stable financial profile.

You can also take advantage of RBC's 120-day rate hold, which allows you to lock in a rate for up to 120 days. This gives you time to complete your home purchase or refinance without worrying about rate fluctuations.

When you speak with an RBC mortgage specialist, be prepared to discuss your financial situation and ask about current special offers. It's often possible to secure a rate that is lower than the advertised posted rate, especially if you have a strong credit history and are purchasing a property with a sizable down payment.

• Negotiate with RBC directly—don't assume the posted rate is final.
• Improve your credit score and save for a larger down payment to qualify for better rates.
• Use RBC's 120-day rate hold to lock in a rate while you finalize your mortgage.

Special Rates for Purchases, Switches, and Refinances

RBC offers special rates for different transaction types, including purchases, switches, and refinances. These are typically discounted from the posted rates and may vary based on the mortgage term and whether it's a variable or fixed rate.

As of August 2026, RBC's special 5-year variable rate for purchase and switch transactions was RBC Prime minus 0.500%, which equated to 3.950%.

For fixed rates, RBC offered a 5-year fixed closed special rate of RBC Prime plus 0.000%, which was 4.480% for purchase and switch transactions. However, note that special offers can be withdrawn or changed, so always verify the current rate on RBC's official page.

• Special rates apply to purchases, switches, and refinances, often at a discount.
• High-ratio mortgages can qualify for a deeper discount (e.g., 5-year variable at Prime minus 0.800%).
• Rates are subject to change; check current offers before applying.

Rate insurance discounts

Mortgage default insurance can lead to a lower interest rate. Because the insurer protects the lender from default risk, the lender may offer a reduced rate to the borrower. This is why RBC's special rates for high-ratio mortgages—those that require default insurance—are often lower than uninsured rates.

For example, RBC's 5-year variable special rate for insured high-ratio mortgages was 3.650%, compared to 3.950% for uninsured purchase or switch transactions, according to RBC's rate page in August 2026.

Just be sure to factor in the insurance premium when calculating your overall costs.

• Insured mortgages often qualify for lower rates due to reduced lender risk.
• RBC's high-ratio rates are an example of insurance discounts in action.
• The insurance premium adds to your mortgage costs, so weigh the benefits carefully.

How RBC Rates Compare to the Prime Rate

RBC's variable mortgage rates are expressed as a discount or premium off the prime rate. For example, the special 5-year variable rate is Prime minus 0.500%, meaning you pay the prime rate minus half a percentage point. This is a common structure: as the Bank of Canada adjusts its policy rate, the prime rate moves, and your variable rate adjusts accordingly.

For fixed rates, RBC uses a different benchmark. The posted 5-year fixed closed rate was Prime plus 0.000%, which at the time of research was 4.480%. This means the fixed rate was essentially set at the prime rate, though fixed rates are influenced by longer-term bond yields, not directly by prime.

When comparing RBC's rates to the prime rate, remember that prime itself can change. Tracking the Bank of Canada's announcements can give you a sense of where variable rates may be headed, but fixed rates depend on other economic factors.

• Variable rates are often quoted as “Prime minus X%” and shift when prime changes.
• Fixed rates are not tied to prime; they're influenced by bond yields and funding costs.
• RBC's posted 5-year fixed closed rate and 5-year open rate differ significantly: 4.480% vs. 7.780% as of August 2026.
