Fixed vs variable rate on a personal loan
UpdatedJuly 3, 2026· 5 min read· Équipe Prêtwise
A fixed rate keeps your payment identical for the entire life of the loan, while a variable rate follows the lender’s prime rate and can push the cost of your borrowing up or down. In Canada, most personal loans are fixed rate; a variable rate often starts a little lower, but it exposes you to increases. The right choice depends on how much room your budget has and your tolerance for uncertainty.
Fixed rate: predictability first
With a fixed rate, the rate is locked in when you sign and never moves. Your monthly payment stays the same from the first payment to the last, no matter what market rates do. You know the total cost of borrowing from day one, which makes budgeting simple.
It is the most common structure for personal loans in Canada, at banks and online lenders alike. The trade-off: if market rates fall after you sign, you keep paying the agreed rate unless you refinance — which can come with fees.
Variable rate: how your rate can move
A variable rate is usually expressed as “prime + X%”. Prime is the lender’s reference rate, which closely tracks the Bank of Canada’s policy rate. When the Bank of Canada raises or lowers its rate, yours follows, usually within days.
Two mechanisms exist depending on the contract:
- Adjustable payment: your payment rises and falls with the rate. Your budget has to be able to absorb the increases.
- Fixed payment, variable split: the payment stays the same, but a rate increase raises the share going to interest and shrinks the share paying down principal. The result: the loan can take longer to pay off and cost more overall.
In Canada, variable rates show up mostly on lines of credit and on some bank personal loans. Always ask which mechanism applies.
An illustrative example: what it means in dollars
These figures are purely illustrative — no rate is guaranteed, and your actual offer depends on the lender and your file.
Picture a $10,000 loan over 3 years:
- Illustrative fixed rate of 11%: a payment of about $327 per month, for roughly $1,790 in total interest. Those amounts will not change.
- Variable rate starting at 9.5%: an initial payment of about $320. If rates stay flat, you pay less interest than with the fixed option. But if the rate climbs to 12.5% after a year, your payment (or your repayment timeline) increases, and the total cost can end up higher than the fixed rate.
The starting gap between fixed and variable is often modest on a personal loan. Always compare the two by APR, which includes fees on top of interest, and work out the total cost under a rate-increase scenario before choosing.
Who each option suits
A fixed rate suits you if:
- your budget is tight and a payment increase would be hard to absorb;
- you want to know the total cost the day you sign;
- you value peace of mind over the chance to save a few dollars.
A variable rate can suit you if:
- your budget has real breathing room and can handle an increase of several points;
- you plan to repay quickly, which limits your exposure to fluctuations;
- you accept the risk of a higher cost in exchange for a starting rate that is often lower.
A reminder: whichever option you pick, your starting rate depends first on your credit score and financial profile. A strong file with Equifax or TransUnion matters more than the choice between fixed and variable.
Questions to ask the lender
Before signing, get clear answers — ideally in writing — to these questions:
- Is the rate fixed or variable, and what is the APR including all fees?
- If the rate is variable: is it the payment that changes, or the length of the loan?
- Is there a cap on how high the rate or the payment can go?
- Can I convert the variable rate to a fixed rate later, and at what cost?
- Is there a penalty if I pay the loan off early?
A reputable lender answers these questions without hedging. Cost-of-borrowing disclosure is regulated by law in Canada: you must receive the total cost before you commit.
Next steps
The choice between fixed and variable matters, but the lender you choose matters even more. Get pre-qualifications from several lenders — banks, credit unions, online lenders — and compare the APRs of both structures side by side. Our guide on the personal loan explains how to evaluate an offer beyond the rate. A few hours of comparison shopping can save you hundreds of dollars in interest.

Frequently asked questions
Are most personal loans in Canada fixed or variable rate?+
Most term personal loans in Canada come with a fixed rate: the rate and payment stay the same from start to finish. Variable rates are more common on lines of credit and on some loans offered by banks and credit unions.
Can my payment go up with a variable rate?+
Yes, it can. Depending on the contract, a rise in the prime rate either increases your payment or increases the portion of each payment that goes to interest — which stretches out your repayment. Ask the lender which of the two mechanisms applies before you sign.
Is a variable rate always lower than a fixed rate at the start?+
Often, but not always. The starting variable rate is usually a little lower because you accept the risk of fluctuation. The gap varies by lender and rate environment: compare both offers by APR at the time of your application.
Can I switch from a variable to a fixed rate partway through?+
Some lenders allow it, sometimes with fees or by refinancing the loan. Nothing guarantees it: if this option matters to you, confirm in writing that it exists and on what terms before signing.
