A bank business line of credit (BLOC) and a merchant cash advance both deliver working capital to a small business, but the products sit at opposite ends of the cost / speed / approval triangle. The honest comparison requires walking through five dimensions: cost, speed, approval, repayment mechanics, and renewal behavior.
Cost comparison, $100K accessed for 9 months.
| Product | Stated rate | Effective APR | Total cost on $100K |
|---|---|---|---|
| Wells Fargo / Chase BLOC, prime + 2.5% | 11% APR | 11% | ~$5,000 |
| Regional bank BLOC | 8–14% APR | 8–14% | ~$5,000–$8,000 |
| Bluevine / OnDeck online BLOC | 25–45% APR | 25–45% | ~$15,000–$28,000 |
| 1.25 factor MCA, 9 months | n/a (factor) | ~42% APR | $25,000 |
| 1.30 factor MCA, 9 months | n/a (factor) | ~50–65% APR | $30,000 |
A traditional bank BLOC is 4–6x cheaper than an MCA per dollar accessed. That headline is true, and it is the single most important number a merchant should anchor on if a BLOC is realistically available.
Approval reality (2026 Federal Reserve SBCS data).
- Bank BLOC approval rate for SMBs under $1M revenue: roughly 28%.
- Bank BLOC approval rate for SMBs $1M–$10M revenue: roughly 56%.
- MCA approval rate (across paper grades): roughly 64–72%.
A 580 FICO sole proprietor with 14 months of operating history and $35K/month deposits will get a "no" or "we will pull your application after 60 days of review" from Wells Fargo. The same merchant gets an MCA approval in 24–48 hours.
Speed comparison.
- Bank BLOC origination: 4–8 weeks (application, underwriting, appraisal of personal guarantee, doc review, closing).
- BLOC draw after approval: 1–3 business days to ACH.
- MCA origination to wire: 4 hours to 3 business days for clean files.
Repayment mechanics.
A BLOC is revolving: borrow $40K, pay it down, borrow $20K, balance compounds at the agreed APR on whatever you carry. Interest-only payments are typically allowed. Principal is due on the maturity date (often a 1-year renewal cycle).
An MCA is non-revolving: take a $40K advance, repay a fixed dollar amount daily until the total repayment (advance × factor) is collected. You cannot redraw the same MCA. To get more capital you stack a second MCA or refinance the first into a larger one — both expensive.
Renewal mechanics.
Bank BLOCs renew annually. The bank may reduce the limit, raise the rate, or non-renew if your covenants slip. Renewal costs nothing in fees in most cases.
MCAs do not "renew" — they pay off, and your broker offers a new MCA at 40–70% of the original balance (the "renewal MCA"). This compounds your cost: you are paying the factor twice on the rolled balance.
When the BLOC is the right answer.
- 2+ years operating history, profitable, accountant-prepared financials.
- Personal credit 680+, no recent bankruptcies.
- Existing banking relationship with the bank (deposit account 1+ year).
- Time horizon: you can wait 4–8 weeks for the money.
- Need is working-capital cyclical (seasonal inventory, AR gaps, payroll bridging).
When the MCA is the right answer.
- Need money in days, not weeks.
- Personal credit 580–680 or recent bankruptcy.
- Under 2 years operating, or revenue declining quarter-over-quarter.
- Already declined by primary bank for BLOC.
- Need is one-time (tax payoff, judgment settlement, single inventory buy).
The hybrid play. Sophisticated SMB owners apply for a bank BLOC even when not urgently needed, get the line, and keep it ready. When a fast need arises, draw the BLOC first; only use MCA for amounts beyond the BLOC limit or for needs the BLOC cannot fund in time.
Common confusion. First, "online BLOCs (Bluevine, OnDeck) are like bank BLOCs" — they are revolving lines, but their effective APRs (25–45%) approach MCA territory; the speed advantage erases the cost advantage. Second, "I can get a BLOC and an MCA simultaneously" — most BLOC agreements include negative covenants prohibiting additional debt without consent; stacking an MCA may trigger default on the BLOC. Third, "the BLOC interest is tax-deductible but the MCA factor cost is not" — the MCA factor cost IS deductible as cost of capital under IRC 162, though the deduction timing differs (it accrues over the repayment period, not upfront).
As of 2026-06-30, the playbook. Apply for the bank BLOC first, even if you do not need money today. Get the line. Hold it. Only take an MCA when the BLOC is exhausted, declined, or too slow for the immediate need.
Related terms
- MCA vs loan (legal distinction) — An MCA is legally a purchase of future receivables, not a loan. This distinction exempts MCAs from state usury caps but requires specific contract structure — including reconciliation provisions.
- Merchant cash advance (MCA) — A lump-sum advance against future revenue, repaid via fixed daily ACH or a percentage of card sales. Legally a sale of future receivables, not a loan.
- APR-equivalent — The annualized percentage rate implied by a factor-rate MCA. A 1.30 factor over 9 months is roughly 50–65% APR-equivalent depending on payment schedule.
- Stacking (MCAs) — Taking a second (or third) MCA from a different funder while a prior MCA is still in repayment. Default risk skyrockets; it breaches most original-funder contracts.
