The First Thing to Know: MCAs Don't Have Interest Rates
It is critical to understand that merchant cash advances (MCAs) do not have an Annual Percentage Rate (APR) or a traditional interest rate like a business loan. Instead, they use a factor rate.
This is the single most important concept to grasp when evaluating an MCA. A factor rate is a simple multiplier, expressed as a decimal like 1.2 or 1.4. To determine your total payback amount, you multiply the amount of cash you receive (the advance) by this factor rate. The result is a fixed, total repayment amount that is determined before you receive any funds.
Here’s a conceptual example:
- Advance Amount: The cash you receive upfront.
- Factor Rate: The multiplier assigned by the MCA provider.
- Total Payback Amount: (Advance Amount) x (Factor Rate)
The cost of this financing is a flat fee, which is the difference between the total payback amount and the advance you received. Crucially, this cost does not change whether you pay it back in four months or twelve months. This is fundamentally different from a loan where interest accrues over time. Because the cost is fixed regardless of the repayment speed, paying it back faster can materially change the effective APR, making MCAs one of the most expensive forms of business financing available.
