What Is a Credit Utilisation Ratio, and How Much Does Paying Down Help?

Your credit utilisation ratio is the balance you owe on a revolving account divided by that account's limit. On a single personal line of credit or credit card, it is one division. Across everything you owe on revolving credit, it is your total balances divided by your total limits — a weighted figure, not an average of the individual ratios. Paying a balance down reduces the ratio by the amount you pay divided by your total revolving limits, which is why the same payment can move two people's numbers by very different amounts.

Which accounts carry a utilisation ratio

Utilisation only exists where there is a limit you can borrow against, repay, and borrow against again. That is revolving credit, and the distinction matters: a large instalment balance can dominate what you owe without showing up in this ratio at all.

• Carries a ratio: credit cards, store cards, unsecured personal lines of credit, secured lines of credit such as a home equity line of credit, and overdraft protection where the lender reports it as a limit.
• No ratio: instalment credit — car loans, mortgages, personal instalment loans and student loans. These report a balance and a payment history, but there is no limit to divide that balance by.

Canada has two national credit reporting bureaus, Equifax Canada and TransUnion Canada, and a free copy of your credit report is available from each. The Financial Consumer Agency of Canada explains what those reports contain and how scores are built from them.

Calculating it on one account

The formula is balance ÷ limit. Two details change the result more than the arithmetic does.

Which balance is reported

Most lenders report the balance as at your statement date, or another fixed date in the month — not the balance on the day you make a payment. If you pay by the due date but keep spending, the figure that lands on your report can be higher than what you think you owe. Someone who clears their card every month can still show a ratio on the report.

Which limit is used

If your limit drops — because a lender trims it, or because a change went unnoticed — your ratio rises immediately even though you have not borrowed another dollar. The same balance over a smaller denominator is a bigger number. This is the most common way people end up with a ratio they did not create through spending.

Calculating it overall

Your aggregate ratio is built from the totals, not by averaging your individual ratios. Add every revolving balance, add every revolving limit, divide. That makes it a weighted average, and the weighting has consequences:

• A nearly maxed account with a small limit contributes very little to the total.
• A large limit at a moderate ratio can move the aggregate more than a small limit at a high ratio.
• Two people can share the same aggregate ratio while one holds several comfortable accounts and the other sits close to the limit on one large account.

Credit scoring models are not published in full, so nobody outside the bureaus can say exactly how much weight this ratio carries. What is public is the general principle: the Financial Consumer Agency of Canada lists how much of your available credit you are using among the factors behind a credit score, alongside payment history, how long accounts have been open, the mix of credit you hold and how often you apply for new credit.

What changes the number, and in which direction

The balance reduction that actually improves it

Because the overall ratio is total balances ÷ total limits, a payment of any size reduces it by that amount divided by your total limits. Everything else follows from that one relationship:

• If your total revolving limits are modest, a payment moves the ratio noticeably.
• If your total limits are large, a payment that feels significant can barely register in the aggregate.
• A limit reduction — a closed account, or a lender trimming your limit — raises the ratio with no change in your debt at all.

If the aggregate figure were your only goal, a payment would have the same effect wherever it went. In practice it is not the only goal: individual account ratios also shape how a file is read, and an account sitting close to its limit is the one that stands out. Paying the account you are closest to maxing out serves both measures, and paying before the reporting date means the smaller balance is the one that gets recorded.

Where a personal line of credit fits

A personal line of credit is revolving credit. It has a limit, so it has a ratio, and it reports the same way a card does. That produces a counter-intuitive result: shifting a balance from a card to a line of credit does not reduce the total you owe and, if both limits stay the same, does not reduce your aggregate ratio either. It only changes which account looks busy. If the line has a larger limit, the aggregate ratio falls — but the freed-up card is still there, and spending against it again puts you back where you started, or further behind.

A home equity line of credit is also revolving, but secured against your property. At federally regulated lenders these lines are generally limited to 65% of appraised property value, with total secured lending usually capped at 80%, as the Financial Consumer Agency of Canada describes. A large denominator cuts both ways: payments move your aggregate ratio slowly, but a given balance sits at a lower ratio.

A practical order of operations

1. Get your report from each national bureau — a free copy is available from both.
2. List every revolving account with its balance, its limit, and the date the lender reports.
3. Work out the ratio on each account and the aggregate across all of them.
4. Identify your reporting dates. A payment made just before the reporting date shows up on that cycle; one made just after generally waits a month.
5. Direct extra money to the account closest to its limit first.
6. Keep paid-off accounts open unless they carry a fee you do not want to pay — closing them removes the limit from your total.
7. Stop adding new balances while you work the number down. The ratio falls when the numerator falls or the denominator rises; new spending does neither.
8. Check again after a full reporting cycle. Reporting dates differ by lender, so a single report may not yet reflect what you have paid.

What does not help

• Paying off an instalment loan to improve this ratio. There is no limit, so there is no ratio to improve, though it may affect other parts of your file.
• Checking your own credit report. That is not an application for credit and does not change your file.
• Shuffling balances between revolving accounts when the total limits stay the same.
• Closing accounts you no longer use. It usually works against you.

How this fits with the rest of your file

Utilisation is one input among several. Payment history, account age, credit mix and how often you apply for new credit all feed the same score, so a healthy ratio does not cancel out a missed payment. Serious debt problems are also recorded for a long time: a consumer proposal stays on a credit report for three years after completion, or six years from filing, whichever comes first, and a first bankruptcy for six years after discharge, according to the Financial Consumer Agency of Canada. Only a licensed insolvency trustee can administer a consumer proposal or a bankruptcy, and trustees are regulated by the Office of the Superintendent of Bankruptcy Canada.

If you have a complaint about a federally regulated financial institution, the Financial Consumer Agency of Canada handles it. Provinces license and supervise most other lenders, and each province has a consumer protection office.

How you choose to restructure or repay debt depends on your own circumstances. Where the amounts are significant, regulated professional advice is appropriate.

loanwolf.ca is a matching service, not a lender. It does not make loans, set rates or make credit decisions, and it cannot tell you what ratio any particular lender will want to see. It connects your request with lenders and lending partners who may be able to help, and the lowest rates in any market are only ever available to the most qualified applicants — so what you are offered will depend on your file.
