HELOC Interest Rate
The variable rate on a home equity line of credit, usually set as the lender's prime rate plus a spread set by the lender..
The HELOC interest rate is the variable rate charged on a home equity line of credit, normally quoted as the lender's prime rate plus a spread. Prime moves with the Bank of Canada's policy interest rate, so the rate paid on a line of credit can change whenever the central bank moves its target, even if the spread itself stays the same.
How the HELOC interest rate is determined
A home equity line of credit is secured by the borrower's home, which is generally why its rate sits below unsecured credit such as a credit card or an unsecured line. The pricing has two parts. The first is the benchmark: the lender's prime rate, which lenders move in step with changes to the Bank of Canada's policy rate. The second is the spread added on top of prime, sometimes called the margin.
Lenders set that margin using several factors. The loan-to-value ratio against the property matters, because a smaller loan relative to the home's value generally supports a tighter spread. So do the borrower's credit history, verified income, property type, and whether the line is a stand-alone product or is combined with a mortgage in a readvanceable plan registered by a collateral charge. A combined product may be priced differently from a stand-alone line, and the way it is registered can affect the cost of moving to another lender later.
No live lender rate is quoted here. To see the current policy rate, check the Bank of Canada's website; to see the prime rate that applies to a particular product, check the lender. The prime rate guide explains how the benchmark is published and why lenders may post the same prime.
Why the rate moves and what happens to the payment
Most HELOCs in Canada are variable and adjustable: when prime rises or falls, the interest charged on the outstanding balance changes, which changes the payment. Many lines require only interest during the draw period, so a rate increase shows up right away as a higher monthly cost rather than being absorbed by a longer amortization.
Some lenders offer a fixed-rate portion inside a line of credit, or a facility that lets a borrower lock a slice of the balance into a term. That portion is priced more like a mortgage, using Government of Canada bond yields and a term premium rather than prime. Borrowers who want payment certainty sometimes split their borrowing between a variable line and a fixed term.
The spread is generally set when the account is opened, but lenders normally reserve the right to change the terms or the limit. Read the credit agreement rather than assuming the pricing is permanent.
How HELOC rates compare with other borrowing
The table below describes how each product's rate is constructed. It does not list current rates, which change with the market.
| Product | How the rate is set | Security | Repayment |
|---|---|---|---|
| HELOC | Prime plus a lender spread; moves with prime | Registered against the home, often as part of a collateral charge | Usually an interest-only minimum; revolving |
| Variable-rate mortgage | Prime or a benchmark, with a discount | Charge on the home | Principal and interest over a set amortization |
| Fixed-rate mortgage | Government of Canada bond yields, plus a term premium, then discounted | Charge on the home | Principal and interest, payment fixed for the term |
| Second mortgage | Lender or private pricing, usually a wider spread | Registered behind the first mortgage | Varies by lender |
| Unsecured line or credit card | Lender's own pricing, no collateral | None | Varies; minimum payment often small |
Who a HELOC rate typically suits
A line of credit tends to suit homeowners who have built equity and want flexible access to it: staged renovations, short-term cash-flow gaps, a bridge between transactions, or consolidating higher-cost debt. The HELOC guide covers how these products are structured and drawn.
The trade-off is behavioural as much as financial. An interest-only minimum means the balance does not fall on its own, and a revolving balance keeps compounding while rates float. A line that suits a short, planned use can become expensive if it is treated as permanent financing, and rising prime affects it immediately.
Renewal, repayment, and lender demand
Most HELOCs are open and do not carry a fixed term, so there is typically no prepayment penalty for paying the balance down or closing the line. A line combined with a mortgage is more complicated: the mortgage component has a term and renewal date, while the revolving portion usually continues unless the lender changes its terms.
Many agreements contain a demand feature, meaning the lender can reduce, suspend, or call the line, and limits are often reviewed periodically or when an attached mortgage comes up for renewal. A decline in property value can also affect what the lender is willing to advance. Model payment scenarios with the HELOC payment calculator before drawing.
What to check before choosing one
- Confirm the benchmark and the spread, and whether the lender can adjust either.
- Ask whether the line is stand-alone or bundled into a readvanceable plan, and how it will be registered.
- Check the maximum loan-to-value the lender will allow, and whether the limit can be reduced at review.
- Ask about set-up, appraisal, and discharge costs, and whether the lender charges to re-advance.
- Note that federally regulated lenders apply an affordability test to secured lines, qualifying borrowers at a rate above the contract rate; confirm the current rule with OSFI.
- Check the Bank of Canada for the policy rate and the lender for its posted prime before comparing offers.
Frequently asked questions
Is a HELOC rate always prime plus a spread?
Most home equity lines of credit are priced as prime plus a spread, and the size of that spread depends on the borrower, the property, and the lender. A few products use a different benchmark, and some offer a fixed-rate portion. Because prime moves with the Bank of Canada's policy rate, the rate you pay changes over time even when the spread does not.
What happens to my HELOC payment when the prime rate rises?
On an adjustable line, the interest cost rises as soon as prime rises, and so does the payment, since most lenders require at least the interest each month. A higher balance magnifies the effect. Borrowers who want a steady payment can ask about locking part of the balance into a fixed term, or model higher-rate scenarios with a HELOC payment calculator.
Can a lender reduce my HELOC limit or demand repayment?
Many line of credit agreements include a demand feature that lets the lender reduce, suspend, or call the line, and limits are often reviewed periodically or when an attached mortgage renews. Lenders may also re-check the loan-to-value ratio. That is one reason a revolving line is not a substitute for long-term fixed financing.
How is a HELOC rate different from a mortgage rate?
A HELOC is usually priced off prime plus a spread, is revolving, and carries an interest-only minimum, so the balance does not fall on its own. A mortgage rate is priced off bond yields or prime for a defined term with scheduled principal payments. Secured line pricing is often below unsecured credit but can be above the deepest discounted mortgage rates.
