What Is a Credit Card Grace Period?
The grace period is the window of time between your statement closing date and your payment due date during which you owe no interest on new purchases — provided you paid your previous statement balance in full.
In plain terms: if you pay off your entire balance every month, you never pay interest on purchases. That is the grace period working in your favour.
Under the federal Credit Business Practices Regulations (part of the Bank Act), Canadian issuers must provide a minimum 21-day grace period on new purchases when no balance was carried forward from the previous billing cycle. This is a legal floor — some cards offer 25 days.
How the Billing Cycle Works
Understanding the grace period requires understanding three key dates:
| Date | What it Means |
|---|---|
| Statement (closing) date | The last day of your billing cycle. Purchases after this date appear on the next statement. |
| Statement due date | The date your payment must be received. At least 21 days after the statement date. |
| Transaction date | The day you made a purchase. Used to calculate interest if you carry a balance. |
Example:
- Statement closes: May 15
- Payment due: June 5 (21 days later)
- You made purchases between April 16 and May 15
- If you pay the full $1,200 statement balance by June 5, you pay zero interest
When You Have a Grace Period — and When You Don’t
You have a grace period when:
- You paid your full previous statement balance by the due date
- You are making new purchases (not cash advances)
You lose the grace period when:
- You carry any balance forward, even $1
- You paid only the minimum payment or a partial payment
Once lost, interest on new purchases accrues from the transaction date — not the due date. That means a purchase you make on June 1 starts accumulating interest immediately if you had a balance from last month.
There is never a grace period for:
- Cash advances (ATM withdrawals, convenience cheques)
- Balance transfers (unless a promotional 0% offer applies)
- Some gambling transactions coded as quasi-cash
The Minimum Payment Trap
Many cardholders believe that making the minimum payment preserves their grace period. It does not.
Paying the minimum means you carried a balance. The issuer will charge interest on:
- The remaining balance from last month
- New purchases in the current cycle — from their transaction date
This is called residual interest or trailing interest, and it catches many Canadians off guard. Even if you pay the full “new statement balance” next month, you may still owe a small residual interest charge because interest accrued between the statement date and when the issuer received your payment.
How to Restore Your Grace Period
If you’ve been carrying a balance, here’s how to restore the interest-free grace period:
- Pay the full statement balance on or before the due date — not just the minimum
- Wait one full billing cycle — the grace period is typically restored from the next statement date
- Watch for residual interest — you may see one more small interest charge on your next statement even after paying in full. This is normal and should be the last one.
What 19.99% Actually Costs
Most Canadian credit cards charge 19.99% per annum on purchases when no grace period applies. That rate sounds abstract, but here’s what it means day-to-day:
| Balance Carried | Daily Interest (19.99%) | Monthly Cost |
|---|---|---|
| $500 | $0.27 | ~$8.33 |
| $1,000 | $0.55 | ~$16.66 |
| $3,000 | $1.64 | ~$49.97 |
| $5,000 | $2.74 | ~$83.29 |
A $3,000 balance carried for 12 months costs roughly $600 in interest — wiping out any rewards earned during that period.
Grace Period vs. Promotional 0% Offers
Some cards offer promotional 0% interest on balance transfers or purchases for a set period (typically 6–12 months). These are different from the standard grace period:
| Feature | Grace Period | Promotional 0% |
|---|---|---|
| How long | 21–25 days | 6–12 months typically |
| Applies to | New purchases | Balance transfers or purchases |
| Requirement | Pay full balance monthly | Meet minimum payment |
| After it ends | Standard rate applies if balance carried | Reverts to 19.99% on remaining balance |
Promotional offers can be valuable for large purchases or debt consolidation, but the standard grace period is better for everyday spending — as long as you pay in full.
Low-Rate Cards: An Alternative
If you regularly carry a balance, a low-rate credit card may cost less than a standard card — because the grace period is rarely in effect for you anyway:
| Card | Rate | Annual Fee |
|---|---|---|
| MBNA True Line Gold Mastercard | 8.99% | $39 |
| MBNA True Line Mastercard | 12.99% | $0 |
| Scotiabank Value Visa | 12.99% | $29 |
| BMO Preferred Rate Mastercard | 12.99% | $29 |
At 8.99% instead of 19.99%, a $3,000 balance costs roughly $270/year instead of $600 — a $330 annual saving.
