RBC Line of Credit: Rates, Limits, and How It Works (2025)

There’s a reason lines of credit are often described as the Swiss Army knife of borrowing: you draw exactly what you need, pay interest only on that amount, and reuse the funds without reapplying. RBC’s Royal Credit Line is one of Canada’s most widely offered unsecured products, yet many borrowers aren’t sure how its variable rate works or when it beats a personal loan — so let’s walk through the limits, costs, and trade-offs to help you decide.

Maximum unsecured credit limit: $100,000 ·
Annual fee: $0 ·
Interest rate structure: Variable (Prime + margin) ·
Minimum payment: Interest on outstanding balance ·
Typical credit score required: 660+ (good)

Key details of the Royal Credit Line at a glance.

How much can you get on a line of credit with RBC?

Your credit limit depends on income, credit score, and whether you offer collateral. Unsecured lines start at $5,000 and can go up to $100,000 (RBC Royal Bank product details).

Factors that determine your credit limit

• Credit score: A score above 660 (good) generally qualifies you for standard products; a score above 700 can unlock lower margins (RBC Wealth Management (financial literacy guide)).
• Income and debt ratios: Your total borrowing capacity is capped by your debt-to-income ratio.
• Collateral: Secured lines against home equity allow limits up to 65% of your home’s value minus any existing mortgages (RBC Royal Bank product details).

How to increase your RBC line of credit limit

Request a limit increase online or in-branch. RBC will review your income, payment history, and credit utilization. A strong track record of on-time payments and lower debt ratios improve your chances.

How does a line of credit work in RBC?

A line of credit gives you a revolving pool of funds. You can borrow up to your limit, repay any amount, and borrow again without reapplying (RBC Royal Bank official product page). Interest is charged only on the amount you draw.

How interest is calculated on a line of credit

• Interest is computed daily on the outstanding balance and charged monthly.
• Rate is variable: RBC Prime Rate plus a margin that depends on your creditworthiness.
• For example, if Prime is 5.70% and your margin is 5%, you pay 10.70% on the cash you actually use.

What is the minimum payment?

You are required to pay at least the interest charged on your outstanding balance each month (RBC Royal Bank official product page). Paying only the minimum keeps the debt alive indefinitely; paying more reduces interest costs.

How is an RBC LOC different from a loan?

Six differences, one pattern: a line of credit is revolving and flexible; a personal loan is a one-time fixed installment.

When to choose a line of credit vs a personal loan

• Choose a line of credit if you need continuous access to funds for home renovations, emergencies, or debt consolidation.
• Choose a personal loan if you want a fixed rate and fixed monthly payment for a defined purpose like a car purchase or vacation (NerdWallet Canada (personal finance comparison)).

Pros and cons of each option

What is the disadvantage of a line of credit?

Risks of variable interest rates

The biggest downside is that your rate can change. Since 2022, the Bank of Canada has raised its key rate from 0.25% to 5.00%, pushing variable rates higher. A line of credit at Prime + 5% would have climbed from 5.25% to 10.00% — doubling the cost of carry.

How to avoid overspending on a line of credit

• Treat it as a safety net, not an income supplement.
• Set a personal limit below your maximum credit line.
• Automate a fixed payment each month to pay down the balance faster.

What is the RBC line of credit interest rate?

RBC’s Royal Credit Line rate is RBC Prime Rate plus a margin. The margin varies by creditworthiness and product type (RBC Royal Bank product details).

How the interest rate is determined

• RBC Prime Rate – currently 5.70% (as of late 2024). This is the base.
• Your margin – can range from 3% to 6% depending on credit score, income, and product (unsecured vs secured).
• Resulting rate: Prime + margin = e.g., 5.70% + 5% = 10.70%.

Current RBC prime rate and your margin

RBC updates its prime rate in lockstep with the Bank of Canada. The margin you receive is not publicly advertised; you learn it during the application process. According to Bankrate (rate comparison site), typical unsecured line of credit rates in Canada range from 8% to 32%, whereas personal loans range from 8% to 36%.

Steps to Apply for an RBC Line of Credit

1. Gather your personal information (SIN, income details, employment history).
2. Check your credit score – above 660 improves your chances.
3. Apply online at RBC Royal Bank, in-branch, or by phone.
4. Provide details on any collateral if seeking a secured line.
5. Receive a decision typically within 1–3 business days.
6. If approved, sign the agreement and set up your access (online banking, cheques).

The Royal Credit Line is a flexible, low‑cost borrowing option that lets you access funds when you need them, at a competitive rate.

Lines of credit often have lower interest rates than credit cards and can be lower than personal loans, depending on your creditworthiness.

For the typical Canadian borrower, the choice between an RBC line of credit and a personal loan comes down to predictability versus flexibility. If you value a fixed payment and a clear end date, a personal loan is the safer path. If you want the ability to draw only what you need and pay it back on your own schedule — and you can resist the temptation to carry a balance — the Royal Credit Line offers cheaper rates than a credit card and a lower minimum payment than a loan. The implication for Canadian households: know your credit score first, then decide.
