# Business credit cards as financing: when they work

**Short answer:** A business credit card is cheap financing only if you repay inside the billing cycle or a promotional period. Carrying a balance is the expensive part. Federal limits on raising card rates cover consumer accounts, not business cards (12 CFR 1026.3(a), 1026.55(a)).

## What a card does well

A card gives you short-term, revolving credit for purchases, with no new loan application each time. The Federal Reserve Board describes business cards as similar to consumer cards, used as needed for business expenses.

Cards are common. In the Federal Reserve Banks' 2026 survey, credit cards were among the most common products firms used regularly. Also, 29% of firms sought a card in the prior 12 months. Among regular card users, 58% used only a business card, 8% used only a personal card and 34% used both.

A card works best for purchases you can pay off within weeks, such as supplies, software and travel. If your card has a grace period, you get float between the purchase date and the payment date. Rewards are a bonus, not a reason to borrow.

## What carrying a balance costs

Suppose the card charges 24% a year on balances you carry, and a term loan charges 12%. These are illustrations, not quotes.

- **Carry $10,000 for six months with no paydown.** Card interest: $10,000 × 24% × 6/12 = $1,200. Loan interest over the same period: $10,000 × 12% × 6/12 = $600.
- **Pay it down evenly.** Pay $10,000 down in equal steps over six months and you owe about $5,000 on average. Card interest is about $5,000 × 24% × 6/12 = $600. The loan costs about $300.
- **Rewards.** A 2% cash-back card on $30,000 of annual spending earns $600. If you also carry an average balance of $5,000, interest is $5,000 × 24% = $1,200. Net: $600 − $1,200 = −$600.
- **Promotional offer.** A 0% offer on a $12,000 purchase costs nothing if you pay $1,000 a month for 12 months. If $6,000 remains when the offer ends, interest runs $6,000 × 24% ÷ 12 = $120 a month.

The pattern is simple. A card is cheap when the balance is zero by the due date. It is expensive when it is not.

## How business cards differ legally

Consumer cards carry federal protections that business cards mostly lack.

- **Business-purpose credit is exempt.** Regulation Z is the rule behind consumer credit disclosures and card protections. It excludes credit extended primarily for a business purpose (12 CFR 1026.3(a)(1)). A few card provisions still apply to business cards (comment 3-1).
- **Rate-increase limits cover consumer accounts.** Regulation Z limits rate and fee increases on a credit card account under a consumer credit plan (12 CFR 1026.55(a)). A business card falls outside that rule.
- **Some protections remain.** Regulation Z sections 1026.12(a) and (b) still apply to business cards. They cover card issuance and a cardholder's liability for unauthorized use.
- **No APR rules for small business credit generally.** The Federal Reserve Board says Truth in Lending disclosure standards do not apply to small business credit.

Read your card agreement for how and when the issuer can change your rate, fees or limit. Check whether you are personally liable for the balance. Of firms with debt in the Federal Reserve Banks' survey, 59% secured it with a personal guarantee. Ask whether your card is one of them.

## When a card is a bad idea

- **Core funding for a new business.** Suppose you put $15,000 of startup costs on cards and carry it for a year at 24%. Interest on the untouched balance is $15,000 × 24% = $3,600.
- **Large or long-lived purchases.** A term loan spreads the cost over the asset's life. In the example above, its assumed interest is half the card's.
- **Covering payroll or taxes with no repayment plan.** A business whose costs exceed its cash does not fix that by moving the gap to a card.
- **Mixing business and personal charges.** A mixed card complicates your books. It also complicates an SBA refinance, which needs you to certify that card debt was used exclusively for the business.
- **Letting the limit set the budget.** A high limit measures what the issuer will lend, not what the business can repay.

## Moving card debt into a loan

If balances have piled up, an SBA loan can refinance business credit card debt. Under SBA's rules, card debt is eligible if the applicant certifies the proceeds were used exclusively for the business (SOP 50 10 8.1, App. 14, Para. A.1.c). The lender can rely on your certification.

Card debt is exempt from SBA's payment-improvement test. It must still be current for at least the last 12 months or the life of the loan, whichever is less (App. 14, Para. A). The lender needs the latest statement showing the account holder and the balance.

A bank term loan can also pay off cards. Ask what it requires, and compare the total cost with your current plan.

## Using a card well

- **Pay the full statement balance** each month, and set up the payment so a busy week cannot miss it.
- **Keep business and personal charges apart.** Separate cards make bookkeeping and later lender reviews simpler.
- **Calendar the promotional end date,** and plan to clear the balance before it.
- **Treat the limit as a ceiling,** not a target. Borrow only against sales you can name.
- **Keep one funding source for each need.** Short purchases go on the card. Long-lived purchases go on a loan.

## Questions to ask before you apply

- What is the rate on purchases, and is there a higher penalty rate?
- When does a promotional rate end, and what rate follows?
- What are the annual, late and foreign-transaction fees?
- Am I personally liable, and does the issuer report to my personal credit file?
- Can the issuer cut my limit, and how much notice does it give?
