Many business owners carry balances month to month on cards. Card APR is often well above what a business line of credit costs for the same working capital. Credit cards are easy to use, and cost doesn't feel painful until the statement arrives.
This briefing does the math that most owners skip. It compares the actual all-in cost of a revolving credit line against a business credit card across five dimensions: rate, limit, rewards, credit profile impact, and operational fit.
The goal is a decision framework, not a verdict. Both products have a place in a well-structured business credit stack. But the balance of that stack matters. If you're evaluating how a revolving LOC compares structurally to non-revolving alternatives, see our revolving vs. non-revolving LOC breakdown.
The Structural Difference That Drives Cost
A business line of credit and a business credit card are both revolving credit products. However, they operate on fundamentally different cost structures.
A LOC funds directly to your bank account. You can pay any business expense: payroll, vendor invoices, rent, tax deposits. The interest rate is negotiated at origination based on your creditworthiness and is typically tied to a benchmark rate (prime + margin). You pay interest only on the drawn balance.
A business credit card charges purchases at point of sale. The rate is set by the card issuer and is often higher than a comparable LOC. The interest calculation is statement-cycle-based: if you pay your full statement balance before the due date, you pay zero interest. If you carry any balance, interest accrues on the full unpaid amount at the card's APR. Card APRs are often high, and some rewards cards cost more.
The structural trap is this: cards offer a grace period (often about 21 to 25 days). Many business owners believe they're using free money. They are, but only until they can't pay the full balance. The moment a balance carries over, the card's true cost reveals itself.
Rate Reality: Typical APR Ranges
The rate gap between business LOCs and business credit cards is often wide. Ranges below are estimates and vary by lender and credit profile.
Business Line of Credit Rates
- Bank LOCs: Variable, often priced as Prime plus a margin. The WSJ Prime rate was 7.00% as of Oct. 21, 2026. Qualified borrowers with strong credit and stable revenue tend to get lower margins.
- Credit union LOCs: Often priced competitively for members with strong profiles. Check current rates.
- Online lenders: Often roughly 15% to 35% APR or more (estimate). More accessible but usually more expensive.
Business Credit Card Rates
- Standard business cards: Variable, often roughly 18% to 24% APR (estimate).
- Rewards cards (travel, cash back): Often priced higher than standard cards. The rewards premium is real.
- Charge cards (American Express, some corporate cards): No preset revolving limit, but balances must be paid in full monthly, so APR is irrelevant if used correctly.
For illustration, assume a 22% card APR and a 10% LOC rate. That is a 12-point gap. On a $50,000 balance carried for 12 months, that gap costs about $6,000 in simple interest. Illustrative example, not a quote.
Business LOC at an assumed 10% APR
$50,000 balance · 12 months
Annual interest cost
Business Credit Card at an assumed 22% APR
$50,000 balance · 12 months
Annual interest cost
That $6,000 annual difference is real margin for a small business.
Credit Limit Ceilings: Where Cards Can't Scale
Beyond rate, the structural limitation of business credit cards is their credit limit ceiling.
Business card limits often start low and vary widely by issuer. Premium business cards offered to established companies with strong revenues may reach higher. Corporate charge cards sometimes have no preset spending limit, but they require full monthly payment and are underwritten based on the corporation's overall credit profile.
Business lines of credit scale differently. A well-qualified business can often access much larger limits through a bank LOC. Asset-based LOCs tied to accounts receivable can reach even higher for businesses with strong A/R. For any business needing six figures in revolving working capital (for payroll coverage, seasonal inventory builds, or large-vendor payment cycles), credit cards often cannot provide the required credit limit.
This ceiling issue is not just about the maximum amount. High utilization on a business credit card carries credit score consequences (discussed below). A business carrying $40,000 on a $50,000 card (80% utilization) faces a different credit profile than a business with $40,000 drawn on a $300,000 LOC (13% utilization). Illustrative example.
The scaling rule: If your working capital need exceeds $75,000 on a recurring basis, a business line of credit is often the better fit. Credit cards at that level often carry high rates and can create credit utilization problems.
The Rewards Math: Does 2% Cash Back Justify 20%+ APR?
This is the calculation most business owners never complete.
The Rewards Scenario
Assume a business spends $50,000 annually on a 2% cash-back card. Rewards earned: $1,000. If the balance is paid in full every month, the card is functionally free. The benefit is $1,000 with zero interest cost. This is the case where cards win outright.
The Carry Scenario
Now assume the business carries a $30,000 balance month-to-month at 22% APR while still making $50,000 in annual purchases. Rewards earned on purchases: $1,000. Interest cost on the carried balance: $6,600 per year. Net outcome: negative $5,600. The rewards earned about 15 cents for every dollar of interest paid. Illustrative example, not a quote.
Rewards cards are profit centers for issuers because many cardholders carry balances. The rewards program is funded by the interest paid by those balance-carriers, including potentially you. The moment you carry any balance month-to-month, the rewards math inverts.
The Better Model
Use a rewards card for purchases you will pay in full every 30 days. This includes vendor payments, subscriptions, travel, and operating supplies. Draw from your LOC for working capital needs you can't pay in full immediately. This hybrid approach captures the rewards upside without triggering the interest cost. See also our broader LOC vs. credit card comparison for additional use-case analysis.
Impact on Business Credit Profile
How each product reports to credit bureaus creates meaningfully different outcomes. This affects your business credit score and future financing options.
Credit Card Reporting
Business credit cards may report to business credit bureaus (Dun & Bradstreet, Experian Business, Equifax Business) as revolving credit. The key variable: utilization. Credit scoring models penalize high revolving utilization, both personal and business models. Carrying a $40,000 balance on a $50,000 card creates 80% utilization on that tradeline, which can suppress your credit scores.
Personal liability is also more common on business credit cards than business owners expect. Many small business cards require a personal guarantee, and some issuers report to personal credit bureaus as well. A business card showing up on your personal credit report with high utilization affects your personal borrowing capacity. This includes mortgage eligibility.
LOC Reporting
Reporting for business LOCs varies by lender. Some report as installment-style credit and others as a separate revolving facility. The utilization impact may be lower in some cases. Additionally, having a LOC with available capacity signals financial strength to other lenders reviewing your business credit file.

Check Capital Eligibility →When to Use Each, and How to Use Both Together
The answer is not one or the other. It's a tiered strategy where each product performs its optimal role.
Use Your LOC For:
- Payroll bridging when revenue timing is off
- Inventory purchases over $10,000 that won't clear within 30 days
- Vendor payments requiring ACH or check (not card-eligible)
- Tax payments or quarterly estimates
- Any expense you cannot pay in full within the card's grace period
Use Your Business Credit Card For:
- Daily operational expenses under $5,000 paid in full monthly
- Travel, meals, and entertainment (category rewards)
- Software subscriptions and recurring SaaS expenses
- Vendor purchases where card acceptance earns rewards and the balance clears in full
The Combined Stack
The optimal structure is a bank or online LOC sized to your working capital need. Use it for large or time-sensitive needs. Pair it with one or two rewards cards for daily operational spending paid in full each statement cycle. The LOC costs nothing when undrawn. The card may earn rewards on purchases cleared within the grace period. Together, they provide both scale and efficiency that neither product delivers alone.

Frequently Asked Questions
Is a business line of credit cheaper than a business credit card?
For a balance carried month to month, usually yes. Bank LOCs are often priced below business credit cards. In an illustrative case, a $50,000 balance carried 12 months costs $5,000 at 10% versus $11,000 at 22%. Illustrative example, not a quote. Rewards programs rarely close this gap for persistent balances.
What are the credit limit differences?
Business credit card limits often top out well below line of credit limits. Business LOCs can reach six figures or more. For large working capital needs, cards simply cannot scale to the required limit.
Do business credit card rewards justify the higher APR?
Only if you pay in full every month. A 2% cash-back card earns $1,000 on $50,000 in spending. Carry a $30,000 balance at 22% APR and you pay $6,600 in interest. That's a net loss of $5,600. Rewards math only works at zero carried balance.
How does a business credit card affect my credit score differently?
Cards report revolving utilization. High utilization, often above 30%, can lower credit scores. Some LOCs report as installment-style credit. Large card balances can hurt future financing options.
Can I use a business line of credit like a credit card?
Not for point-of-sale purchases. LOC funds transfer to your bank account. You pay expenses from there. For any expense over $5,000 to $10,000 that you'd otherwise carry on a card, a LOC draw is often cheaper.
