Merchant cash advance vs line of credit: which is better for a cash gap

A business line of credit usually costs less than a merchant cash advance because you pay only on what you draw, so use an MCA only when you cannot get a line in time.

Cash gaps come back. Pick the tool you can use more than once.

Most owners who search this are not funding a big project. They are trying to cover a gap: payroll before a client pays, stock before the busy season. The right tool for a gap is one that charges you only while the gap is open.

That is what a line of credit does, and why NerdWallet's MCA guide tells owners that having one already open lets them tap working capital quickly when they need it [2]. If you cannot get a line today, an MCA can still bridge one gap. Here is how to tell the difference in dollars.

A $20,000 cash gap, paid back over 6 months (our calculation)

MCA: 1.30 factor rate, no fees, business-day debits. Line of credit: one draw paid back in 6 equal monthly payments at the low and high end of NerdWallet's published APR range [1], draw and maintenance fees not included.
OptionYou useTotal costPayment
Merchant cash advance [2]$20,000$6,000$206.35 every business day
Line of credit at 10% APR [1]$20,000$587.37$3,431.23 a month
Line of credit at 99% APR [1]$20,000$6,155.03$4,359.17 a month
Line of credit at 99% APR, only $8,000 drawn [1]$8,000$2,462.01$1,743.67 a month
MCA when you only needed $8,000 of it$8,000$6,000$206.35 every business day

The MCA works out to about 109% estimated APR. Only the most expensive published line comes close, and even then a line charges nothing on money you never draw.

Is it a fit for you?

It fits when

  • A line of credit fits gaps that repeat: seasonal stock, slow-paying customers, uneven payroll weeks.
  • A line of credit fits if your score is near 600 or better and your revenue history is steady.
  • An MCA fits one urgent gap when no line is open and none can be opened in time.
  • An MCA fits if your credit rules out a line but your card sales are strong and steady.

Look elsewhere when

  • An MCA is a poor fit for a gap that will come back next quarter; you would pay the full cost again.
  • A line is a poor fit for a large one-time purchase; a term loan or equipment financing usually fits better.
  • Neither fits a business that loses money most months.
  • A line with a fee on every draw is a poor fit for many small draws.

How each one charges you: on the draw vs on the whole amount

A line of credit is a limit you can draw against. NerdWallet describes it simply: you pay only on the money you withdraw, and as you repay you can borrow up to the limit again [5]. If you never draw, you pay only whatever fees the line carries.

A merchant cash advance is a lump sum in exchange for a fixed amount of your future sales. The cost is the advance times the factor rate, typically 1.1 to 1.5 [2], set on the day you sign. Leave half the cash sitting in your account and the cost does not change.

The "unused cash" trap

You expect a $20,000 gap, take a $20,000 advance at 1.30, and the gap turns out to be $8,000. You still deliver $26,000 of sales to the funder. With a line, the same surprise means you drew $8,000 and paid only on $8,000.

Getting approved: the line is harder, the MCA is faster

This is where the MCA earns its place. Lines of credit want more from you. NerdWallet says some online lenders accept a score of 600, while banks and credit unions typically want a score close to 700 or higher [1]. Fundera's past MCA customers had scores around 600 and just six months in business [4], and many MCA funders weigh sales more than credit.

Where you apply matters too. In the Federal Reserve's 2024 Small Business Credit Survey, applicants at small banks were the most likely to be fully approved, at 54% [6]. If you have a business account at a community bank, ask there before you take an advance.

Payment rhythm: daily debits vs monthly or weekly payments

MCA collection usually comes every business day or every week. Lines vary: NerdWallet notes that lines of credit may require daily, weekly or monthly repayment [1], so ask before you assume a monthly bill. A weekly line payment is still easier to plan around than a daily debit, and it ends when the draw is repaid.

  • Ask a line lender: Is the rate fixed or variable? Is there a draw fee, a monthly fee or an annual fee?
  • Ask an MCA funder: Is the debit a true split of sales or fixed? How do I request reconciliation?
  • Ask both: What is the total cost in dollars if I use the full amount for six months?

Reading the APR on each disclosure

Where state disclosure laws apply, both products may come with an APR, but they are figured differently. California's rule for open-end lines tells providers to assume you draw the full limit at the start, make no other draws and pay only the minimum on time [3]. That gives a worst-case use of the line. An MCA's estimated APR instead depends on how fast your sales are projected to pay it back.

So a line's disclosed APR is a fair ceiling, and you will usually pay less by drawing less or repaying sooner. An MCA's estimated APR can go up if your sales come in faster than projected, because the same fixed cost is paid in less time. Our factor rate to APR guide shows the math.

Fees that change the math on both sides

The headline numbers leave out fees, and both products can carry them. NerdWallet warns that origination, draw and account maintenance fees can raise the overall cost of a line of credit [1]. On the MCA side, administrative or underwriting fees add to the cost and are often taken out of the advance before you receive it [2].

How fees work on each (ask for every one in writing)
FeeOn a line of creditOn an MCA
UpfrontOrigination fee, on the limit or the first drawUnderwriting or setup fee, taken out of the advance
Per useDraw fee on each draw, at some lendersNone; you take the whole amount at once
OngoingMonthly or annual maintenance fee, at some lendersAsk; any charge beyond the payback should be listed
Early payoffAsk about prepayment penaltiesOften no saving unless the contract has a discount

A hypothetical draw fee, worked out

Say a line charges a 2% fee on each draw. Drawing $8,000 four times in a year costs $640 in draw fees on top of the APR. That is real money, but it is still far below paying a fixed MCA cost four separate times.

The 2% is an example, not a typical figure. Use the actual fee schedule from any line you are offered.

A two-step plan: bridge once, then open the line

If an advance is your only option right now, use it to bridge one gap and start building toward a line at the same time. Keep deposits in one business account, keep the balance from overdrafting, and apply for a line as soon as you have the history a lender wants. The next gap is then a draw, not a new advance.
