The fundamental difference in one paragraph
A merchant cash advance is a one-time purchase of future receivables. You get a lump sum today, and the funder takes a fixed daily or weekly ACH debit from your business account until the agreed total payback is collected. The price is expressed as a factor rate (1.20 to 1.49) applied to the advance. A business line of credit is a revolving credit facility. The lender approves you for a maximum limit, you draw whatever amount you need (from $1 up to the limit), pay interest only on what you have drawn, pay it back, and draw again. The price is expressed as an APR (10 to 30 percent).
Side-by-side comparison
When MCA wins
You need cash this week
MCA funds in 24 to 48 hours. LOC takes 2 to 5 days to set up before you can draw. If the use case is "payroll Friday" or "emergency equipment repair tomorrow," MCA is the only product that consistently delivers.
FICO is under 600
Most LOC lenders want 600+ FICO and 24 months of business credit history. MCAs routinely fund at FICO 500-600 because the underwriting is on bank deposits, not personal credit.
You have a specific one-time need
If the use is a known dollar amount for a known purpose (inventory load for the season, an equipment buy, an acquisition deposit), a fixed-amount MCA may actually beat a revolving LOC on simplicity and total focus.
Business is under 12 months old
Most LOC lenders require 12 to 24 months in business. MCAs go as low as 3 months for strong revenue files. If you have not hit a year yet, MCA is often the only option.
When line of credit wins
Cash needs are ongoing and unpredictable
You don't know when you will need capital or how much. Could be next Tuesday, could be in 6 weeks. An LOC sits ready and costs you nothing until you draw. An MCA forces you to commit to a fixed amount today whether you need it all or not.
Cost matters more than speed
LOC APR at 15 percent costs roughly half what an MCA factor rate of 1.40 over 12 months costs in total interest. If you have a week to set up the LOC and the need is not crisis-level, the LOC is materially cheaper.
You are building business credit
LOCs report to business credit bureaus (D&B, Experian Business, Equifax Business). On-time use and paydowns build the business credit history that opens better products later. MCAs do not report and do not build credit.
Your business is seasonal
If revenue swings between $40K in slow months and $200K in peak months, a fixed daily MCA debit crushes you in slow months. An LOC lets you draw in slow months, pay down aggressively in peak months, repeat.
The hybrid play: run both at once
Sophisticated borrowers often run both products simultaneously, each for its strength. A common pattern: a $50K line of credit serves as the always-on safety net for slow weeks, and an occasional $75K MCA covers one-off opportunities that exceed the LOC limit. Each product does what it does best and you do not overcommit on either one.
If you go this route, set up the line of credit FIRST. Lenders see existing MCA daily debits on bank statements, which can lower your LOC limit or rate (because the MCA debits look like existing obligations). Get the LOC approved while your bank statements are clean, then add an MCA later if a specific need arises.
The decision matrix
Three questions decide it:
- How fast? Need money in 48 hours = MCA. Can wait a week = LOC.
- What FICO? Under 600 = MCA (LOC won't qualify). 650+ = LOC available, weigh on use case.
- What is the use case? One-time fixed-amount spend = either works. Ongoing or unpredictable = LOC.
The honest answer for most owners: you probably want a line of credit if you can get one. The MCA exists for the situations where the LOC is not available or not fast enough. See our line of credit page or the MCA overview to dig deeper on whichever fits.
