If you’re researching the American Express® Business Line of Credit, there’s a good chance you arrived here a little confused — because this product used to be called Kabbage. Amex acquired Kabbage in 2020, folded the lending business into American Express, and rebranded the line of credit under its own name. So when you see “Amex Business Line of Credit,” you’re looking at the Kabbage engine with the American Express badge on it.

I spent years on the lender side of small-business finance, and I’ll tell you up front: the thing that makes this product unusual isn’t the brand. It’s the cost structure. Most lines of credit quote you an APR. This one charges a flat monthly fee on each draw — a model that’s easy to understand on the surface and surprisingly easy to misjudge once you do the math. That’s the part most reviews gloss over, and it’s the part that decides whether this line is a smart tool or an expensive one for your situation.

Here’s how it actually works, who it fits, and how to check whether you’d qualify without guessing.

What the Amex Business Line of Credit Is (and Isn’t)

The American Express Business Line of Credit is a revolving line of credit for small businesses — you’re approved up to a set limit, you draw what you need, you repay over a fixed term per draw, and the credit frees back up as you pay it down. It’s funded and serviced by American Express National Bank.

A few things it is not, because the branding invites confusion:

• It is not an American Express business credit card. Different product, different application, different terms. If you’re comparing the two, that’s a real decision — see our business line of credit vs. business credit card breakdown.
• It is not a marketplace. When you apply, you’re applying to American Express. They approve you on their terms or they don’t. That’s different from a platform like Lendio, where one application gets shopped to many lenders at once — more on why that matters below.
• It requires linking a business bank account that shows business revenue to apply and qualify (a business checking account, or an alternative like PayPal or Square) — no separate American Express Business Checking account is mandated.

The honest one-line summary: it’s an established, well-capitalized lender (you’re not dealing with a fly-by-night MCA shop), with a fast online application and a fee-based cost model that rewards short, disciplined borrowing and punishes long, slow paybacks.

How the Amex Business Line of Credit Works

This is the section to read twice, because the mechanics drive the cost.

When you’re approved, you get a credit limit — currently $2,000 to $250,000*. You then take individual draws against that limit. Each draw is repaid over a fixed term — offered in 6-, 12-, 18-, or 24-month options — in monthly installments.

Here’s the key part: instead of a traditional interest rate, each draw carries a flat monthly fee. That fee is expressed as a percentage of the draw amount, charged every month over the term. The total fee percentage you’ll pay is set when you take the draw, based on your business profile and the term you choose. Longer terms generally carry a higher total fee.

The single most important move with this product: convert the total fees into an APR before you compare it to anything else. A flat monthly fee feels cheaper than it is, because “1.5% a month” doesn’t read like the annualized number it actually represents. Our factor rate vs. APR explainer walks through exactly how to do that conversion so you’re comparing apples to apples — it’s the same trap, different label.

Amex Business Line of Credit Requirements

Here’s where my old job is useful. Online lenders weigh roughly the same three things, in this order: time in business, annual revenue, and personal credit score. Amex’s line-of-credit underwriting leans on revenue and cash-flow consistency more than a traditional bank does — which is why a business a bank turned down can still get approved here.

General eligibility bar (confirm every one of these against Amex’s live page — they move):

• Time in business: at least 12 months*.
• Revenue: average monthly revenue of at least $3,000*.
• Personal credit score: a minimum FICO of 660* at application.
• A linked business bank account that shows business revenue (a business checking account, or an alternative such as PayPal or Square) — no separate American Express Business Checking account is required.
• A personal guarantee is standard for a product like this — expect to personally back the line.
• Operating in an eligible industry — most online lenders restrict certain industries, so check if yours is unusual.

A note from the lender side: a “minimum” is a floor, not a target. Hitting the exact minimum on every metric usually means a smaller limit and a higher fee, not a clean approval. Strength in one area — steady, provable revenue — can offset a soft spot in another, like a thinner credit file. If your score is on the low end, read our bad credit eligibility guide before you apply anywhere; applying scattershot is how people rack up hard inquiries and lower their own odds.

What the Amex Business Line of Credit Actually Costs

This is the part I won’t fake a number on, and you should be suspicious of any review that does.

The cost is not a single advertised APR. It’s a set of monthly fees quoted per applicant, per draw, based on your revenue, credit, time in business, and the term you pick. Watch these line items, because they’re where the real cost lives:

• The total monthly-fee percentage — the sum of every monthly fee across the draw’s term. This is your true cost of capital for that draw. Amex’s published total-fee ranges run roughly 3%–9% (6 mo), 6%–18% (12 mo), 9%–27% (18 mo), and 12%–18% (24 mo)* of the amount borrowed.
• Term length — a longer term spreads payments out but generally raises the total fee. Borrowing more slowly costs more.
• Whether there’s a benefit to early payoff — confirm whether paying a draw off early actually saves you remaining fees or whether the fee is effectively locked in.
• Any account or maintenance costs — note that Amex states it charges no application, origination, annual, or monthly maintenance fees on this product; the fee is the monthly draw fee.

The honest framing: a fee-based line like this can be reasonable for short, fast paybacks where you draw, use the money, and clear it quickly. The longer you stretch a draw, the worse the effective APR tends to get relative to a conventional bank line. If you qualify for a bank line of credit or an SBA option and you can wait, those will almost always cost less.

Amex vs. The Alternatives

You shouldn’t judge this product in a vacuum. Here’s the honest competitive picture:

How the Amex line compares (illustrative)

Option	Speed	Typical cost	Best fit
Amex Business Line of Credit	Fast	Fee-based — convert to APR before judging	Established business in the Amex ecosystem needing fast, short-term draws
Bluevine	Fast	Rate-based (varies by lender) — quote a simple-interest/APR figure, not a fee	Worth comparing head-to-head — see our Bluevine review
OnDeck	Fast	Higher than a bank	Established business, bank said no — our OnDeck review
Bank line of credit	Slow	Lowest	Strong credit, time to wait, existing bank relationship
SBA loan/line	Slowest	Low	Best long-term cost if you qualify and can wait weeks

* Illustrative — speed and cost vary by lender and applicant; verify current terms before applying.

The single most useful move before committing to any one lender: don’t apply to just one. Get matched across several at once, then take the Amex offer and put it next to the others — especially since the fee model makes a head-to-head APR comparison essential.

The Verdict: Who Should Use the Amex Business Line of Credit

Bottom line: the American Express Business Line of Credit is a legitimate, capable product — the Kabbage engine with a stronger balance sheet behind it. Its fee-based pricing is genuinely good for short, disciplined borrowing and genuinely worse for slow, stretched-out paybacks. So treat it as a strong contender for the right use case, not an automatic yes — and only accept a draw once you’ve converted the fees to an APR and seen at least one competing offer next to it.
