If a funding rep called you back the same day and offered cash “approved” against your future sales, you were probably looking at a merchant cash advance — not a line of credit. The two get pitched as if they’re interchangeable. They are not. One is a flexible, lower-cost credit line you draw on as needed. The other is one of the most expensive ways to fund a small business that still exists legally.
I spent years on the lender side reviewing these applications, and the single most common reason owners ended up in an MCA wasn’t that it was the right fit — it was that nobody explained the math to them first. So that’s what this page does. Plain English, the real cost mechanics, and an honest answer on when (if ever) an MCA makes sense over a line of credit.
The short version
A business line of credit (LOC) is revolving credit. You’re approved for a limit, you draw what you need, you pay interest only on what you’ve drawn, and the room you repay becomes available again. Cost is quoted as an APR — an annual percentage rate you can compare apples-to-apples against anything else.
A merchant cash advance (MCA) is not a loan at all, legally. It’s the sale of a slice of your future revenue at a discount. The funder gives you a lump sum today and collects a fixed total back — usually as a daily or weekly cut of your sales or a fixed ACH debit — until the full amount is paid. Cost is quoted as a factor rate, not an APR. That difference is the whole game, and it’s where owners get hurt.
| Business line of credit | Merchant cash advance | |
|---|---|---|
| What it is | Revolving credit you draw as needed | Purchase of future receivables (lump sum now) |
| Cost is quoted as | APR (annual %) | Factor rate (e.g. a multiplier on the amount) |
| Reusable? | Yes — repaid room frees up again | No — one lump sum, repaid and done |
| Typical repayment | Monthly; interest only on what you draw | Daily/weekly holdback of sales or fixed ACH |
| Relative cost | Lower | Much higher (often dramatically) |
| Funding speed | Fast to fast-ish — varies by lender | Often same-day / very fast |
| Best for | Ongoing or unpredictable cash-flow needs | Last-resort, short-term gap when nothing cheaper qualifies |

The factor-rate trap: why an MCA costs so much more than it looks
Here’s the part the rep won’t walk you through.
A factor rate is a flat multiplier. If you’re quoted a factor rate of 1.4 on a $50,000 advance, you pay back $70,000 — total. It sounds almost reasonable when you say it that way: “$20,000 to borrow $50,000.” But a factor rate hides two things an APR would expose.
First: the cost doesn’t shrink if you pay it back early. With an APR loan or line of credit, interest accrues over time — pay it off faster and you pay less. With an MCA, you owe the full fixed payback no matter how fast you clear it. Paying early doesn’t save you a dollar of the cost; it just raises the effective APR even higher because you’ve compressed the same fee into less time.
Second: the repayment is fast and frequent. MCAs are typically collected daily or weekly. Because the money is collected so quickly, that “$20,000 fee” is actually being charged over a matter of months, not a year. When you convert a factor rate plus a short, daily repayment into a true annualized APR, the numbers get ugly — industry estimates put MCA effective APRs roughly in the 40% to 350%+ range, depending on the factor rate and how fast the advance is repaid (per Crestmont Capital / Clarify Capital analysis, 2026). For perspective, that $20,000 fee on a $50,000 advance repaid in a few months translates to an effective APR many times higher than a typical line-of-credit rate.
Compare that to a line of credit, where the cost is an honest APR and you only pay interest on the portion you’ve actually drawn. For the same real-world cash-flow gap, the line of credit is, in the large majority of cases, far cheaper — business-LOC APRs commonly run in the single to low-double digits at banks and span a roughly 3% to 60% range overall (per Bankrate, 2026), well below the effective cost of a typical MCA.
The trap in one sentence: an MCA’s factor rate makes the cost look small and fixed, while the daily repayment makes the true APR enormous — and paying it off early doesn’t help.
How repayment actually feels day to day
This is the part owners underestimate. A line of credit gives you a monthly payment you can plan around. An MCA takes its cut of your sales every business day (or debits a fixed amount weekly).
In a strong sales week that’s tolerable. In a slow stretch — a seasonal dip, a slow month, a big client paying late — the MCA keeps pulling its share while your revenue is down. That’s exactly when businesses get squeezed into “stacking” a second MCA on top of the first to stay liquid, which is how the genuinely dangerous debt spirals start. A line of credit doesn’t behave that way: you simply don’t draw more than you can service, and your repaid room is there if you need it again.
Can you refinance a merchant cash advance with a line of credit?
Sometimes — and if you can, it’s often the smartest move available. Replacing a high-cost MCA (or stacked MCAs) with a lower-APR line of credit or term loan is a real strategy lenders see often. The catch is qualification: if the MCA already has you cash-tight, your numbers may not yet support approval for cheaper credit, and some lower-cost lenders are cautious about businesses with active advances. It’s worth checking your options before assuming you’re stuck.

When does a merchant cash advance ever make sense?
I’m not going to pretend an MCA is never the answer. It can be defensible in a narrow case:
- You need cash immediately (think: today/tomorrow) and the gap is genuinely short-term.
- You’ve been declined for a line of credit and a term loan, so the comparison isn’t “cheaper vs. expensive,” it’s “expensive vs. nothing.”
- You have strong, steady card/sales volume and a clear, quick payoff event coming (a big invoice, a seasonal surge) that makes the short repayment window survivable.
- You understand the total dollar cost and have confirmed it in writing — not just the factor rate.
Outside of that, a line of credit, a term loan, or even a business credit card for smaller short-term needs is almost always the cheaper, saner choice. The whole reason this page exists is that MCAs get sold to plenty of owners who would have qualified for something far cheaper if anyone had checked first.
How to decide: a simple decision path
- Is the need ongoing or recurring? → Line of credit. It’s built for exactly that.
- Can you wait a few days and provide basic financials? → Apply for a line of credit (or term loan) first. Don’t default to the fastest money.
- Were you declined for a line of credit? → Find out why before reaching for an MCA. Fixing a fixable issue (or trying a marketplace that matches you to more lenders) can save you a fortune.
- Do you genuinely need cash today, with no cheaper option that will approve you? → If you proceed with an MCA, get the total payback in dollars and the repayment frequency in writing, and have a concrete plan to clear or refinance it fast.
The verdict
For almost every business, a business line of credit beats a merchant cash advance — it’s cheaper, the cost is transparent (a real APR, not a factor rate), you only pay for what you draw, and the repayment is something you can actually plan around. An MCA is a last-resort instrument: fast, easy to get, and expensive in a way that’s deliberately hard to see until you do the annualized math.
The honest move is simple: try for the line of credit first. Even if you’ve been turned down once, a marketplace application puts your business in front of multiple lenders at once and can surface an offer a single bank declined.

Frequently asked questions
Is a merchant cash advance worse than a line of credit?
In terms of cost, almost always yes. A line of credit charges an APR on only what you draw and lets you reuse repaid credit. An MCA charges a fixed factor-rate fee that doesn’t shrink if you pay early, collected daily or weekly — which makes its true annualized cost far higher. An MCA’s main advantage is speed and looser qualification, not cost.
How is an MCA factor rate different from an APR?
A factor rate is a flat multiplier on the amount advanced (e.g. 1.4 means you repay 1.4× what you received), and it’s fixed regardless of how fast you repay. An APR is an annualized interest rate that reflects time, so paying down faster costs you less. Because MCAs are repaid quickly, converting a factor rate to a true APR usually produces a much higher number than the factor rate suggests — industry estimates commonly put the effective range from roughly 40% to 350%+ depending on repayment speed (per Crestmont Capital / Clarify Capital analysis, 2026).
Can you refinance a merchant cash advance with a line of credit?
Often yes, and it can dramatically cut your cost — but qualification is the hurdle. If an active MCA already has your cash flow tight, you may not yet qualify for cheaper credit, and some lenders are wary of businesses with open advances. Check what you’d actually qualify for before assuming you’re locked in.
Why do merchant cash advances get approved so easily?
Because the funder is buying your future sales, not lending against your credit profile in the traditional sense. Approval leans heavily on your sales/card volume and consistency, so businesses that can’t get a bank line of credit can still get an MCA. That easy approval is exactly why the cost is so high — and why it’s worth exhausting cheaper options first.
Is a line of credit always cheaper than an MCA?
In the large majority of real cases, yes — but confirm the actual numbers. Get the line of credit’s APR and any fees, and get the MCA’s total dollar payback, then compare. Don’t compare a factor rate to an APR directly; they aren’t the same unit. Business-LOC APRs commonly run far below a typical MCA’s effective annualized cost (per Bankrate and Crestmont Capital / Clarify Capital, 2026), but confirm the actual numbers on your specific offers.
