How personal loan rates are actually set.
Most rate quotes are a sum of two numbers — a base rate that floats with the market, and a risk premium specific to you.
The rate quote on a personal loan offer can feel like a single number a lender plucked from the air. It isn’t. Almost every rate, on almost every loan, is the sum of two components — a base rate that the lender doesn’t control, and a risk premium that the lender does. Understanding both halves is the difference between accepting a rate and evaluating one.
The base rate
The base rate is the cost of money for the lender. In Canada, most personal-loan lenders peg their pricing to a public benchmark — typically the Bank of Canada policy rate or a derivative of it, such as the prime rate (which most major banks set as policy rate plus 2.20 percent).1
When the Bank of Canada raises the policy rate, the base rate rises across most lenders within weeks. When the Bank cuts, the base rate eventually falls — though lenders often lag the cuts more than the increases, which is one reason why timing a personal loan around a rate cut rarely produces the savings the borrower hoped for.
The risk premium
The risk premium is what the lender adds on top of the base rate to compensate for the chance you might not repay. It is calculated using a model that weighs five things in roughly this order: your credit score, your debt-to-income ratio, your employment stability, your relationship with the lender, and the loan amount and term.
A borrower with a strong credit score, low debt-to-income, stable employment, an existing relationship with the lender, and a modest loan request might see a risk premium of 4 to 5 percent. A borrower with a marginal score, higher debt-to-income, and no existing relationship might see a risk premium of 12 to 18 percent. The base rate is the same for both. The premium is where the difference lives.
A worked example
Suppose the prime rate is 5.95 percent. Lender A offers you a personal loan at 9.50 percent. Lender B offers 11.25 percent. Lender C offers 14.75 percent.
The implied risk premiums are 3.55, 5.30, and 8.80 percent respectively. The same applicant, the same loan amount, the same term — three different premiums. Why?
Each lender runs your application through their own model. Different lenders weigh the five inputs differently. Some weigh credit score heavily, some weigh debt-to-income heavily, some give weight to existing-relationship factors that other lenders ignore. The result is that the same applicant gets different premiums from different lenders.
This is the practical reason that comparing offers from more than one lender — at the same point in time, with the same loan amount — produces useful information. A single offer is a single model’s opinion. Two offers begin to triangulate.
What you can change in the short term
Most of the inputs are slow-moving. Credit score takes months to move materially. Employment history is what it is. Debt-to-income changes as you pay down debt or earn more, but not overnight.
Two things, however, you can change in the short term:
- Loan amount and term. Smaller loans over shorter terms often carry lower premiums because the lender’s exposure is shorter. If you can borrow $25,000 over 36 months instead of $40,000 over 60 months, the rate you’re quoted will often be lower (though the monthly payment will be higher).
- Existing relationship factors. If you have a long-standing chequing account, a credit card in good standing, or a previously-paid-off loan with the same lender, that information frequently feeds into the premium calculation. It is reasonable to ask whether your existing relationship is being weighed.
What you cannot change
The base rate. The market sets it. Your specific lender doesn’t move it. Lenders that advertise a rate "below market" are almost always offering a teaser rate on a short introductory period, after which the rate resets to market plus your risk premium. The resets are not always disclosed prominently — they live in the fine print.
If the rate you’re quoted seems unusually low compared to the prime rate, read the agreement for a "rate adjustment" or "resetting rate" clause. These are common in subprime lending but appear in mainstream lending as well, particularly on variable-rate loans.
Why two offers from the same lender can differ
Lenders re-price their books periodically. A rate quoted in March may differ from the same lender’s quote in June for the identical applicant, because the lender’s funding cost has changed, their risk appetite has shifted, or both. This is one reason why a soft pre-qualification quote isn’t binding — it’s a snapshot of the lender’s pricing at a specific moment.
When to lock and when to wait
If you have a defined need with a defined timeline — a renovation that begins next month, a wedding date set for June — locking a rate when an acceptable offer comes in is the deliberate choice. The few basis points you might save by waiting are typically outweighed by the planning cost of an uncertain rate.
If the need is exploratory — you’re considering whether to borrow at all — there’s no urgency to lock. Acquiring offers, comparing them, and waiting a week to think doesn’t cost you anything material in most rate environments.
The five-question framework
For any rate quote you receive, ask:
- What is the base rate component, and how is it benchmarked?
- What is my risk premium, and which factors moved it up or down?
- Is the rate fixed or variable for the life of the loan?
- If variable, what is the rate-adjustment clause — when can it move, by how much, and what are the caps?
- Is there a teaser rate or introductory rate that resets?
A lender who can answer all five clearly is operating at the level of disclosure you want. A lender who can’t — or who deflects — is showing you something about how they treat customers after closing.
