Standard Canadian credit cards charge 19.99% on purchases. If you regularly carry a balance month to month, a low-interest card at 8.99%–12.99% saves far more than any rewards programme.

How Much Does a Lower Rate Actually Save?
On a $5,000 persistent balance:
| Rate | Monthly Interest | Annual Interest |
|---|---|---|
| 19.99% (standard) | ~$83 | ~$1,000 |
| 12.99% | ~$54 | ~$650 |
| 8.99% (MBNA Gold) | ~$37 | ~$450 |
The MBNA True Line Gold saves approximately $550/year on a $5,000 balance — minus the $39 fee = $511 net saving annually.
When a Low-Interest Card Beats Rewards
The 19.99% interest on a carried balance erases rewards immediately. A card earning 2% cash back on $2,000/month earns $480/year in rewards. Carrying a $3,000 balance at 19.99% costs $600/year in interest — a net loss of $120.
Rule: If you carry a balance even some months, calculate your average monthly carried balance:
- Average balance × 19.99% / 12 = monthly interest cost
- Compare to cash back you’d earn on your actual spending
- If interest cost exceeds rewards, switch to a low-interest card
Low-Interest vs. Balance Transfer
Balance transfer: 0% promotional rate for 6–12 months on transferred debt — powerful for eliminating a defined lump sum quickly.
Low-interest card: Ongoing 8.99%–12.99% rate — no expiry, no promotional clock. Better for persistent month-to-month carrying.
