A 0% APR business credit card charges no interest on new purchases for an introductory period, most often 12 months on 2026 offers. When the period ends, any remaining balance accrues interest at the card's standard variable APR, commonly 17% to 28%. It works as funding only when you can repay the balance before that date.
How does a 0% intro APR on a business card work?
You get a credit limit, you spend against it, and for the promotional period the issuer charges no interest on qualifying purchases. A few things are easy to miss:
- Minimum payments still apply. You owe a monthly minimum from the first statement. Missing one can end the promotion.
- It usually covers purchases, not cash. Cash advances typically carry a separate, higher APR plus a fee from day one.
- Some offers include balance transfers, usually with a transfer fee.
- The clock usually starts at account opening, not at your first purchase.
Promotional periods vary. Twelve months is the most common length on 2026 business card offers, and a few run 15 to 18 billing cycles. Sagamore's 0% business credit card program targets offers with intro periods of up to 18 months.
What happens when the 0% period ends?
The remaining balance starts accruing interest at the card's regular APR. Nothing is charged retroactively on a true 0% offer, but the jump from 0% to 20-something percent is immediate.
Here's how the payoff pace plays out. Say a coffee roaster puts $40,000 of inventory and equipment on two cards with 12-month 0% offers, and assume a standard APR of 24% after the promotion.
| Monthly payment during promo | Balance at month 12 | Interest in month 13 at 24% APR |
|---|---|---|
| $3,334 | About $0 | $0 |
| $2,000 | $16,000 | $320 |
| $800 | $30,400 | $608 |
The math for the bottom row: $40,000 − (12 × $800) = $30,400. Monthly interest at 24% APR is 2% per month, so $30,400 × 2% = $608, or roughly $7,300 a year if the balance sits there.
The top row is the strategy working. The bottom row is a 24% loan with a 12-month teaser.
What are the risks of using 0% business cards for funding?
Business cards fall mostly outside the CARD Act
The Credit CARD Act of 2009 limits how consumer card issuers can raise rates on existing balances, when they can revoke a promotional rate, and how much notice they must give. As of 2026, those protections apply to consumer cards. For business-purpose cards, federal rules cover only card issuance and your liability for unauthorized use.
In practice, that means a business card issuer can end your 0% rate or apply a penalty APR on whatever terms its cardholder agreement sets, which can include a single late payment. Some issuers voluntarily extend CARD Act-style protections to business customers. Read the agreement and look for it.
You're personally on the hook
Nearly every small-business card requires a personal guarantee. If the business can't pay, you owe the balance. Some issuers also report business card balances to your personal credit reports, which raises your personal utilization and can lower your score. Many report only serious delinquencies, but policies differ by issuer.
Every application is a hard inquiry
Credit card applications aren't grouped the way mortgage or auto rate-shopping inquiries are. Three card applications mean three hard inquiries. FICO scores count inquiries for 12 months, and they stay on your report for two years. If you plan to apply for a mortgage or SBA loan in the next few months, time your card applications with that in mind.
Several promos can end in the same month
Opening two or three cards in the same month means their promotions end in the same month too. A $60,000 combined balance that converts to a standard APR all at once is a much bigger problem than one $20,000 card.
Balance transfers buy time at a price
If you can't clear the balance, a balance transfer to a new 0% card can extend the runway. Transfer fees commonly run 3% to 5%. On $30,000, that's $900 to $1,500 upfront, plus a new hard inquiry and no guarantee of approval.
How much funding can 0% cards realistically provide?
Less than most loans. Limits depend on your personal credit, personal income, and each issuer's appetite. Through Sagamore's program, combined limits typically range from $5,000 to $150,000, usually across 2 to 4 cards applied for in sequence. The program requires a personal score of 650 or higher, and scores above 700 generally unlock the best introductory terms and higher limits.
That makes cards a good fit for inventory, marketing, software, and equipment purchases in the low five figures. They're a weak fit for payroll and rent, which usually have to be paid in cash or by bank transfer, and for anything above roughly $150,000.
How do 0% cards compare with a line of credit or term loan?
| 0% business credit cards | Line of credit | Term loan | |
|---|---|---|---|
| Interest during first months | 0% on purchases during the promo | Interest on drawn balance from day one | Interest from day one |
| After 12 to 18 months | Standard card APR on remaining balance | Same pricing as before | Same fixed payment as before |
| Typical size through Sagamore | $5K to $150K | $5K to $500K | $10K to $2M |
| Minimum credit through Sagamore | 650+ | 500+ | 500+ |
| Repayment | Minimum payment; you set the pace | Repay and redraw | Fixed payments over 6 to 60 months |
| Best for | Purchases you can repay within the promo | Recurring cash-flow gaps | One-time investments with a clear payback |
The cards win on cost only if the balance is gone before the promo ends. A line of credit charges interest from the first draw but never has a rate cliff, and it can be used for cash expenses like payroll. A term loan costs more upfront but locks in a known payment and total cost.
Many businesses use both: cards for purchases they can pay off inside 12 months, and a line of credit for everything else.
How do you use 0% cards without getting burned?
- Do the payoff math before you spend. Divide the balance by the number of months left in the promotion, minus one for margin. That's your real monthly payment, not the minimum on the statement.
- Put every card on autopay for at least the minimum. On a business card, one late payment can cost you the promo rate.
- Put each promo end date on your calendar, with a reminder 60 days out.
- Use the money for things that pay you back inside the promo window. Inventory that sells in 90 days is a good use. A buildout that pays back over three years is not.
- Keep reported balances low before any loan application. If a card reports to your personal file, a high balance can lower your score right when a lender pulls it.
- Don't treat a balance transfer as the plan. It's a backup, and it depends on credit approval you may not get.
When are 0% cards the wrong tool?
- Your personal credit is below 650. Most 0% offers won't approve you, and every decline still costs a hard inquiry. Improve your credit first, or look at products with lower credit minimums.
- You need more than about $150,000.
- You need cash for wages, rent, or taxes.
- Your repayment depends on revenue you don't have a clear line of sight to within the promo period.
If cards cover part of your need but not all of it, one application lets you see card options alongside lines of credit and term loans, and the initial review is a soft credit pull.
