How is an MCA calculated?

A merchant cash advance uses a factor rate rather than an interest rate. The total repayable is simply the advance amount multiplied by the factor rate. Repayment is collected as a daily percentage of your card revenue.

The formulas used are:

Total Repayable = Advance Amount — Factor Rate

Cost of Advance = Total Repayable - Advance Amount

Daily Holdback = (Monthly Revenue / 30) — Holdback %

Est. Months to Repay = Total Repayable / (Monthly Revenue — Holdback %)

Effective APR — (Cost / Advance) / (Months / 12) — 100

The effective APR is an approximation to help compare MCA costs against traditional loans. Actual repayment speed varies with card revenue fluctuations.

Assumptions and caveats

  • Monthly card revenue is assumed to remain constant. Actual revenue fluctuations will change the repayment timeline.
  • The effective APR is an approximation only and should not be compared directly to regulated loan APRs.
  • Some MCA providers charge additional fees not included in the factor rate.
  • Daily holdback assumes 30 trading days per month for simplicity.
  • Results are indicative estimates only. Contact a provider for a formal offer.

Frequently asked questions

A merchant cash advance (MCA) provides a lump sum of capital to a business in exchange for a percentage of future card sales. It is not technically a loan — it is a purchase of future receivables. Repayment adjusts automatically with your card revenue, making it flexible but often expensive.

A factor rate is a multiplier applied to the advance amount to determine total repayment. For example, a factor rate of 1.30 on a £50,000 advance means you repay £65,000 in total. Factor rates typically range from 1.15 to 1.50.

The holdback is the percentage of daily card revenue that is automatically deducted to repay the advance. For example, a 15% holdback on £500 daily card revenue means £75 per day is withheld. The holdback continues until the total repayable amount is fully repaid.

Technically no. An MCA is structured as a purchase of future card receivables, not a loan. This means MCAs are not regulated in the same way as loans and do not have a fixed repayment schedule — repayment fluctuates with your card sales volume.
