Solo Biz Soft Editorial Team A 0% intro APR business credit card charges no interest on purchases, balance transfers, or both, for a set introductory period. It is a genuinely useful tool for financing a one-time expense or paying down other debt interest-free — as long as you understand exactly when the clock runs out.
How long does the 0% period actually last
Most current offers run somewhere between 9 and 18 months, with 12 months the most common length and 18 months close to the longest available on business cards today. The exact length is set by the card, not negotiable, and it starts from account opening, not from your first purchase.
Purchases, balance transfers, or both
Some cards offer 0% on new purchases only, some on balance transfers only, and some on both but for different lengths of time. If your goal is financing a specific upcoming purchase interest-free, confirm the purchase APR offer. If your goal is escaping high interest on an existing balance, you want the balance-transfer offer specifically — run the numbers on the balance transfer calculator to see whether the transfer fee is worth it compared to staying put.
What happens when the intro period ends
Any balance still outstanding when the intro period ends starts accruing interest at the card’s regular ongoing APR, which is typically variable and tied to the Prime Rate. There is usually no grace period or gradual ramp — the switch happens on the next billing cycle. The safest way to use one of these cards is to divide your balance by the number of intro months and pay that much (or more) every month, so it is fully paid off right as the 0% period ends.
The fine print that trips people up
- Balance transfer fees are usually charged upfront, commonly 3% to 5% of the amount transferred, even though the interest itself is 0%
- Some cards void the promotional rate entirely if you miss a single payment, reverting to the regular APR retroactively
- New purchases made after a balance transfer may not get the same 0% treatment, depending on the card
- The 0% rate never applies to cash advances
Frequently asked questions
Is a 0% intro APR card the same as a card with no annual fee?
No, these are separate terms. A card can have a 0% intro APR and still charge an annual fee, or be fee-free with a standard (not promotional) APR. Check both separately.
What credit score do I need?
Issuers generally reserve their best 0% offers for good to excellent personal credit, though exact thresholds vary by issuer and are not published.
Can I extend the 0% period?
No, the length is fixed when you open the account. Some people later apply for a new 0% card and transfer the remaining balance again, though that means another transfer fee.
