How to Underwrite a Merchant Cash Advance

Underwrite a merchant cash advance from bank statements, not tax returns. Measure average monthly deposits, deposit consistency, negative balance days and existing MCA positions, then size the purchase amount so the daily or weekly remittance stays a modest share of receipts. Factor rate, holdback percentage and stacking exposure drive expected loss.

What makes merchant cash advance underwriting different

A merchant cash advance is a purchase of a fixed amount of a business's future receivables at a discount, repaid through a percentage of daily or weekly deposits or card sales. The funder's return comes from the factor rate and how quickly the amount is collected. The risk comes from thin margins at the merchant, volatile receipts, other funders taking positions in the same deposits, and merchants changing bank accounts or closing. Because the merchants are usually small and lightly documented, underwriting relies on recent bank activity, payment processor data and behavioral signals rather than audited financials or collateral.

Funders and their backers view the product as a short-duration, high-loss, high-yield portfolio, so they underwrite at both the merchant level and the vintage level. A capital provider lending to an MCA funder cares about historical collection curves, default and loss rates by vintage, renewal behavior, concentration by industry, and how the funder handles collections and legal recourse. An equity investor in an MCA platform looks at origination cost, broker dependence, repeat customer economics and how the contract terms hold up under state law, since true-sale treatment versus a disguised loan has real legal consequences.

Key metrics

Average monthly deposits

True revenue deposits, excluding transfers and loan proceeds, set the ceiling on how large an advance the merchant can support.

Funders commonly size advances at roughly one month or less of verified average deposits for first positions.

Holdback or remittance percentage

The share of receipts going to the funder determines whether the merchant can keep operating while repaying.

Holdbacks often fall in the 5% to 20% range of receipts, with higher levels signaling strain.

Factor rate

The factor rate fixes the total payback amount and, combined with collection speed, sets the effective yield and the cushion against loss.

Factor rates are commonly quoted between about 1.1 and 1.5.

Negative balance days and NSFs

Frequent overdrafts and returned items indicate the merchant has no buffer to absorb a daily debit.

Many funders decline or reprice when statements show more than a handful of negative days per month.

Existing positions (stacking)

Other MCA debits in the statements reduce free cash flow and raise the chance the merchant defaults on everyone.

Time in business and industry

Newer businesses and certain industries show higher closure rates, which drives default frequency in the portfolio.

Funders often require at least a year in business, though thresholds vary.

How to underwrite it, step by step

Collect the last three to six months of business bank statements and, where available, card processor statements.
Scrub deposits to remove transfers, loan proceeds and refunds, then calculate true average monthly revenue and trend.
Identify existing MCA and loan debits, count negative balance days and NSF events.
Verify the business and owner with identity, lien (UCC), judgment and background searches.
Size the purchase amount and set the factor rate and remittance so the payment is affordable relative to verified receipts.
Confirm the business is operating through a site check or phone verification and confirm bank account access for ACH.
Monitor remittances daily after funding and escalate quickly on missed debits or account changes.

Due diligence checklist

Three to six months of business bank statements

Owner identification and validity guaranty
UCC lien search
Judgment and litigation search
Business registration and good standing
Voided check and ACH authorization
Landlord or lease verification where required
Payoff letters for any positions being refinanced

Key risks and mitigants

Stacking by other funders after closing

Include anti-stacking covenants, file a UCC, monitor bank data where permitted, and set renewal criteria that reward clean behavior.

Merchant switches bank accounts or blocks the ACH

Obtain a validity guaranty covering account changes, monitor daily, and act quickly on missed debits.

Recharacterization of the advance as a loan under usury laws

Use a genuine reconciliation provision that adjusts payments to actual receipts, avoid fixed terms that look like amortization, and get state-specific legal review.

Inflated deposits from transfers or one-time items

Scrub statements line by line and verify against processor data or bank connections rather than PDFs alone.

Business closure or seasonality

Size to trough months, avoid funding into a known seasonal decline, and diversify the portfolio by industry.

Typical financing and deal structure

Individual advances are structured as purchases of future receivables with a specified purchased amount, a factor rate and a daily or weekly remittance, plus a reconciliation right that lets the merchant adjust payments if receipts fall. Owners usually sign a validity or performance guaranty rather than a payment guaranty. At the platform level, MCA funders finance their book through a mix of equity, participations sold to syndicate investors, and senior or mezzanine credit facilities with advance rates against eligible receivables. Those facilities carry eligibility criteria, concentration limits, excess spread and loss triggers, and borrowing base reporting. SBA programs do not finance merchant cash advances.

Red flags

Three or more existing MCA positions in the bank statements
Statements that cannot be verified with the bank or show signs of editing
Deposits dominated by transfers between related accounts
Recent large drop in deposits that the merchant cannot explain
Contract terms with fixed payments and no working reconciliation, which raise loan recharacterization risk

Frequently asked questions

Is a merchant cash advance a loan?

Legally an MCA is structured as a purchase of future receivables rather than a loan, which is why it typically falls outside usury limits. Courts look at the substance: whether repayment is truly contingent on receipts, whether a reconciliation provision works in practice, and whether there is a fixed term. Agreements that behave like loans risk being recharacterized, and some states now require specific disclosures.

How do MCA underwriters analyze bank statements?

They separate genuine revenue deposits from transfers, loan proceeds and refunds, then calculate monthly averages and trend. They count negative balance days and returned items, identify debits from other funders, and look for unusual patterns. The goal is a reliable figure for recurring receipts and a view of how much daily cash the business can spare.

What is stacking in merchant cash advance?

Stacking is when a merchant takes a second or third advance from different funders while earlier ones are outstanding. Each funder draws from the same deposits, so total remittances can exceed what the business can afford. Later positions carry the highest risk. Funders identify stacking from bank statement debits and UCC filings and often include anti-stacking terms in contracts.

How is a factor rate different from an interest rate?

A factor rate is a multiplier on the advance amount that sets the total payback, for example a 1.3 factor on a $100,000 advance means $130,000 is owed. It does not vary with time, so the effective annualized cost depends on how quickly the amount is collected. A short collection period produces a much higher annualized rate than the factor implies.
