How Merchant Cash Advances Work and Why the Loan Goes Higher While the Cash Is Lower

How a Merchant Cash Advance Works

A merchant cash advance (MCA) is not a traditional loan but a purchase of future receivables. The provider advances a lump sum against expected card sales, then recovers funds by taking a fixed percentage of daily card receipts and, optionally, a fixed percentage of ACH payments. Because repayment flows with card traffic, the amount "paid back" can rise when fees and buy rates are applied, even as the business sees less cash in hand, creating a pattern where the loan goes higher while the cash is lower.

Key Mechanics and Cost Levers

Funding and Repstructure

At close, the provider pays a lump sum (often 70–90% of approved advance) and quotes a factor rate (e.g., 1.2–1.5). The total repayment is factor rate × advance. A factor rate of 1.3 on a $10,000 advance means $13,000 must be repaid. Unlike amortizing loans, the payment amount varies with card sales, which can distort perceived cost and cause balances to grow in early statements when fees are front-loaded or card volumes are low.

Repayment Mechanics

Repayment is typically automated via ACH and cardfilelds. Two common splits apply:

• Cardfilelds split: a fixed percentage of daily card sales (e.g., 10–20%) until the obligation clears.
• ACH split: a fixed percentage of ACH deposits (e.g., 15–25%) on a periodic basis.

When cardfilelds are low (seasonality, refunds, chargebacks), the same percentage applied to smaller sales removes less cash, lengthening the term and increasing the effective cost. In contrast, the MCA statement may show a rising outstanding balance if fees are added or slow repayment stretches the pay period.

Cost, APR, and Why the Loan Can Rise While Cash Falls

MCAs rarely quote APR because they are not loans; instead, regulators and lenders focus on total paid vs. advanced. High factor rates and blended fees (application, statement, PCI, funding) can produce effective APRs well above 50–100%. When cardfilelds dip or the factor rate is steep, the remittance removes a smaller cash share, stretching the term. Fees added to the principal and slow remittances can push the statement balance up even as the business receives and spends cash, producing the "loan goes higher while the cash is lower" pattern.

Comparisons and Considerations

• Best suited for short-term, high-cardfileld turnover needs; avoid long-term reliance.
• Negotiate the lowest factor rate possible and confirm fee caps.
• Model repayment under low-sales scenarios to see if the balance can rise while cash falls.
• Check whether the contract allows early payoff without penalties.
• Compare with small business lines of credit or SBA microloans for lower effective cost.

When an MCA Makes Sense (and When It Doesn't)

An MCA can be useful for immediate working capital tied to card sales, such as restocking before peak hours, provided you repay quickly and cardfilelds are stable. It is generally unsuitable for long-term capital needs, low-cardfileld businesses, or when consistent cash flow is uncertain. The structure inherently creates risk that the loan grows while available cash shrinks if fees, low sales, or aggressive remittance splits elongate the term and accumulate costs.

Bottom Line

Merchant cash advances trade simplicity and speed for cost and flexibility risk. Repayment through a percentage of cardfilelds means the cash available to the business can fall while the outstanding balance rises when sales are low or fees are front-loaded. Understand the factor rate, all fees, and the remittance schedule; model outcomes in low-sales periods; and prefer lower-cost alternatives when longer terms are needed.
