What we like, and what we don’t

Worth having

  • Prime plus 5% applies to purchases, balance transfers and cash advances alike
  • That is materially below a standard 20.99% business card
  • It works as a line of credit and a card in one product
  • Aimed at self employed people and small businesses that borrow rather than clear

Watch out for

  • Maximum financing is $10,000, too small to be a primary business card
  • It earns no rewards at all
  • $50 a year for a card that pays nothing back
  • The rate is variable and rises with prime, so nothing here is fixed
  • National Bank publishes no foreign currency conversion fee for this card

What the benefits really mean

Interest is charged at Prime rate + 5% on purchases, balance transfers and cash advances alike. Minimum credit limit $1,000; maximum financing available up to $10,000, subject to credit approval. Fraud compensation plan up to $10,000. Mastercard ID Check. 21-day grace period on purchases paid in full, not applicable to cash advances or balance transfers. No insurance coverages published. NO FIXED APR. National Bank publishes only 'Prime rate + 5%', applied identically to purchases, balance transfers and cash advances. Purchase_apr is recorded as NOT PUBLISHED rather than a computed number. Maximum financing is only $10,000, which makes this unusable as a primary business card for most firms. And it still carries a $50 fee. National Bank publishes no additional card fee, no foreign currency conversion fee and no personal guarantee statement. No insurance coverages at all.

Our verdict

Prime plus 5% on cash advances as well as purchases is the useful part. Most business cards price advances above 22% and start charging the same day, so a business that occasionally needs cash keeps meaningfully more here.

The $10,000 ceiling is what stops it being a serious option. That is not enough working capital for most businesses, so this ends up as a second card rather than a main one, and $50 a year for a second card that earns nothing is a hard sell. TD's Business Select Rate card does the same job at 11.99% with no annual fee.
