Working capital loan vs MCA vs business credit card — which costs least for what use case

A bank or SBA working-capital loan / line of credit is almost always cheapest — typical effective APR of 8–13% versus 18–29% on a business credit card and 40–150%+ effective APR on an MCA. The catch is qualification: you need 2+ years time-in-business, 680+ FICO, and clean bank statements to access the bank/SBA rate. If you can't qualify, the card wins for a short-term gap (under 60 days, paid in full); the MCA is the last resort.

For very short-term gaps — under 60 days — where you're confident you'll pay the balance in full. The card has no draw fee, gives you a 21–25 day grace period on purchases, and earns rewards. A bank LOC may charge a per-draw fee (1–3% on some fintech LOCs) or a monthly maintenance fee, which makes a 30-day card float cheaper. The card loses the moment the balance carries — 24% APR compounds quickly.

When (a) you cannot qualify for a bank LOC or SBA working-capital loan at the size you need, (b) you have a specific, time-bound, ROI-positive use of capital — inventory for a confirmed PO, an emergency equipment repair to avoid a bigger outage, payroll bridge during a known slow week, and (c) you have a credible refi path inside 6–12 months. MCAs are emergency capital, not working-capital primary. The factor rate (typically 1.20–1.50) translates to an effective APR of 40–150%+ when annualized against the actual repayment schedule.

Business credit card: 670+ FICO, basic business documentation, no revenue floor for starter cards. Bank LOC: 680+ FICO, 2+ years time-in-business, $200K+ revenue, clean bank statements. SBA 7(a) CAPLines: 650+ FICO, 2+ years TIB, $250K+ revenue, SBA documentation package. MCA: 500+ FICO, 6+ months TIB, $10K+ monthly business deposits. The floors fall as the price rises.

Yes — and this is the optimal stack for most established small businesses. The card handles small rotating purchases (travel, T&E, software, supplies) and earns rewards; you pay it in full each month. The line of credit sits as standby capacity for inventory, payroll bridges, and AR float at materially lower rate. Card and LOC are complements, not substitutes. The expensive mistake is carrying a card balance month-over-month at 24% when an unused LOC at 11% is sitting beside it.

Generally yes — the cost of an MCA (the difference between the funded amount and the total payback) is a business expense, deductible in the year it accrues. But tax treatment doesn't change the underlying economics: deducting an 80% effective APR doesn't make it cheaper than not having to borrow at that rate. Confirm specifics with your tax preparer; the IRS treats receivables purchases differently from interest-bearing loans in some edge cases.

Card: annual fees ($95–$695+ on premium business cards), foreign transaction fees (1–3%), balance transfer fees (3–5%), cash advance fees (3–5% plus a separately higher APR with no grace period). LOC: monthly maintenance fees ($25–$100 on some bank lines, even at zero balance), per-draw fees (1–3% on some fintech LOCs), unused commitment fees (0.25–0.50% annually on the undrawn portion). MCA: origination/setup fees ($300–$1,500), ACH return fees ($25–$50 per bounced debit), the rate-doesn't-decline-on-early-payoff problem (the factor is owed in full whether you take 4 months or 12).

Bank LOC at 11% APR, 6-month payback: total interest ~$1,650. Business credit card at 24% APR, 6-month payback: total interest ~$3,600. MCA at 1.32 factor, 6-month payback: total cost $16,000 (the factor is the total cost, not annualized). The MCA is roughly 10x more expensive than the bank LOC and 4.5x more expensive than the card on this scenario. On a 12-month need the card-vs-MCA gap narrows somewhat because the card's 24% compounds longer, but bank/SBA stays cheapest at any term.

Almost never. Stacking — taking a second-position MCA on top of existing debt — typically signals to underwriters that you're over-leveraged, and the second-position MCA is priced even higher than the first (factor rates of 1.35–1.55 are typical). If you're considering stacking, the better move is usually a consolidation refi (SBA 7(a) debt refinance, a working-capital term loan, or a higher LOC) — combine the existing debt into one lower-rate facility rather than layering another expensive position on top.

Build the file. 12–24 months of clean banking, growing revenue, established business credit tradelines, and a 660+ FICO unlocks the bank LOC; a 680+ FICO and 2+ years TIB unlocks favorable SBA pricing. In the meantime, use a business credit card for short-term gaps you can pay in full; use an MCA only for ROI-positive, time-bound emergencies. Map the file-build path so you stop paying MCA prices for working capital that should be bank-priced.
