The National Bank Syncro Mastercard is a variable-rate low-interest credit card offered by National Bank of Canada — designed for Canadians who carry a credit card balance and want to minimize interest costs compared to standard 19.99% credit cards. Rather than earning rewards, the card’s value proposition is a significantly lower interest rate (prime + 4% or prime + 8%, depending on the variant), which can save hundreds to thousands of dollars annually for those who carry substantial balances.
Quick Verdict
Best for: Canadians who regularly carry a credit card balance and want to minimize interest costs, particularly those with balances of $3,000+ who are working to reduce debt while keeping a functional credit card.
Not ideal for: Those who pay their balance in full each month — a rewards card delivers more value. Also not ideal for those who want a predictable fixed rate rather than a variable rate that changes with Bank of Canada policy.

The Variable Rate Advantage
The Syncro Mastercard’s core appeal is its variable interest rate, which is tied to National Bank’s prime rate:
Rate comparison (illustrative — verify current rates at nbc.ca)
At a Bank of Canada policy rate of 2.75%:
- National Bank prime rate: ~4.95%
- Syncro (prime + 4%): ~8.95%
- Syncro Plus (prime + 8%): ~12.95%
- Standard credit card rate: 19.99%
Interest savings on a $5,000 balance (per year)
| Rate | Annual Interest on $5,000 |
|---|---|
| Standard credit card (19.99%) | ~$1,000 |
| Syncro Plus (~12.99%) | ~$650 |
| Syncro (~8.99%) | ~$450 |
| Savings vs. standard card (Syncro) | ~$550/year |
For cardholders with $5,000+ in carried balances, saving $550+/year in interest is a compelling argument for the Syncro card even with the annual fee.
Variable Rate Risk
Unlike fixed-rate low-interest cards (Scotiabank Value Visa at 12.99%, BMO Preferred Rate Mastercard at 12.99%), the Syncro rate changes with Bank of Canada rate decisions:
| Scenario | Impact on Syncro Rate |
|---|---|
| Bank of Canada cuts rates | Rate falls — you pay less interest |
| Bank of Canada raises rates | Rate rises — you pay more interest |
| Rates held steady | Rate unchanged |
Between 2022 and 2024, the Bank of Canada raised rates from 0.25% to 5%, which would have pushed the Syncro rate from ~4.25% to ~9.0% (prime + 4%). At peak rates, the Syncro rate approached fixed low-rate card rates.
When variable beats fixed: When rates are high and falling, a variable rate card benefits you as rates decline. When rates are low and rising, a fixed-rate card provides more certainty.
Syncro vs. Syncro Plus: Which Variant?
Verify the current fee and rate for each variant at nbc.ca.
| Variant | Estimated Rate | Estimated Annual Fee | Best For |
|---|---|---|---|
| Syncro | Prime + 4% | Higher (~$100) | Largest balances — lowest rate |
| Syncro Plus | Prime + 8% | Lower (~$35) | Moderate balances — lower fee |
Break-even calculation: The lower-rate Syncro saves more interest but costs more in annual fee. Calculate which is better for your balance:
- If Syncro saves $50+ more in interest than Syncro Plus annually, pay the higher fee for Syncro
- If your balance is modest ($1,000–$2,000), Syncro Plus saves more in net cost
No Rewards: The Trade-Off
The Syncro Mastercard earns no rewards — no points, no cash back. This is the explicit trade-off for the low interest rate. For Canadians who carry a balance, this is the right trade-off: paying 9% in interest instead of 20% saves far more than any rewards programme would earn.
When to switch back to a rewards card: Once your balance is paid to $0 and you can commit to paying in full each month, a rewards card (National Bank World Elite Mastercard at $0/year, Scotiabank Gold Amex at $120/year) will serve you better.

Syncro vs. Other Low-Interest Cards in Canada
| Card | Annual Fee | Rate | Type |
|---|---|---|---|
| National Bank Syncro | ~$35–$100 | Prime + 4% or + 8% (variable) | Variable |
| Scotiabank Value Visa | $29 | 12.99% fixed | Fixed |
| BMO Preferred Rate MC | $20 | 12.99% fixed | Fixed |
| CIBC Select Visa | $29 | 13.99% fixed | Fixed |
| TD Emerald Flex Rate Visa | $25 | Prime + ~4.5% (variable) | Variable |
Fixed vs. variable comparison:
When the Bank of Canada prime rate is below ~8% (i.e., the Syncro rate is below 12%), the Syncro card beats fixed-rate cards in interest cost. When rates rise above 8% prime, fixed-rate cards at 12.99% become more competitive.
In Canada’s 2024–2026 rate environment, the Syncro rate at prime + 4% is competitive when National Bank prime is below 8.99% (~Syncro rate below 12.99%).
Who Is the National Bank Syncro Mastercard Best For?
Ideal cardholders:
- Canadians who carry credit card balances of $3,000+ and are paying 19.99% on a standard card — the Syncro’s lower rate provides significant monthly savings
- Those who believe the Bank of Canada will continue cutting rates (making the variable rate increasingly attractive)
- National Bank clients who want a low-rate card integrated with their National Bank banking relationship
- Quebec-based Canadians with National Bank accounts who prefer their credit card with the same institution
Less suitable if:
- You pay your balance in full every month — no rewards, no benefit; use the National Bank World Elite Mastercard instead
- You prefer interest rate certainty — a fixed-rate card (BMO Preferred Rate, Scotiabank Value) is more predictable
- Your balance is modest ($1,000 or less) — the annual fee makes the savings marginal
Alternatives
| Card | Annual Fee | Rate | Best For |
|---|---|---|---|
| Scotiabank Value Visa | $29 | 12.99% fixed | Predictable low fixed rate |
| BMO Preferred Rate MC | $20 | 12.99% fixed | Lowest-cost fixed rate option |
| CIBC Select Visa | $29 | 13.99% fixed | CIBC clients, stable low rate |
| TD Emerald Flex Rate Visa | $25 | Variable (prime + spread) | TD clients, variable rate |
| National Bank Syncro | ~$35–$100 | Prime + 4% (variable) | NB clients, lowest variable rate |
Bottom Line
The National Bank Syncro Mastercard is a smart choice for debt-carrying National Bank customers who want the lowest possible variable interest rate on their credit card. When the Bank of Canada’s prime rate is moderate (below 8%), the Syncro’s prime + 4% rate delivers meaningful interest savings versus both standard credit cards and fixed low-rate alternatives. The trade-off is no rewards and a variable rate that rises when Bank of Canada rates rise.
For those paying their balance in full monthly, look elsewhere. For those working to eliminate credit card debt while keeping a functional card, the Syncro Mastercard is a valuable tool.
