How Does an MCA Factor Rate Work?

A factor rate is the pricing mechanism most commonly used in a Merchant Cash Advance. Instead of quoting an interest rate, an MCA quotes a factor rate — a decimal multiplier that determines the total amount the business will pay back. Understanding how it works is essential before accepting an MCA.

What a Factor Rate Is

A factor rate is a decimal — typically somewhere between 1.10 and 1.50 — that is multiplied by the advance amount to calculate the total payback. For example, a $100,000 advance at a 1.35 factor rate means the business pays back $135,000 total. The difference — $35,000 — is the cost of the advance.

How the Payback Amount Is Calculated

The math is straightforward: Advance × Factor Rate = Total Payback.

• $50,000 × 1.30 = $65,000 payback
• $75,000 × 1.25 = $93,750 payback
• $100,000 × 1.40 = $140,000 payback

That total payback is then collected through daily or weekly ACH payments over the expected term of the advance.

Why a Factor Rate Isn't an Interest Rate or APR

This is the most important distinction to understand. A factor rate is a flat multiplier — the total payback is fixed from day one and does not change as you pay down the balance. A traditional loan's interest rate, by contrast, accrues on the outstanding principal: as you pay the balance down, you owe less interest. An APR (annual percentage rate) also accounts for the time value of money and the repayment term.

Because a factor rate is a flat cost applied to the full advance upfront, comparing it directly to a loan's APR is misleading. A 1.35 factor rate paid over 6 months represents a much higher annualized cost than the same factor rate paid over 18 months — but the factor rate itself looks identical in both cases.

How Term Affects the Real Cost

The same factor rate can represent very different annualized costs depending on how quickly the advance is repaid. A shorter repayment term means the same total cost is paid over less time — which raises the effective annual cost. A longer term spreads the same cost over more time, lowering the effective annual cost. This is why two advances with identical factor rates can feel very different to a business's cash flow.

What to Ask Before Accepting an MCA

• What is the factor rate, and what is the total payback amount?
• What is the expected repayment term?
• What are the daily or weekly payments?
• What is the effective monthly payment equivalent?
• How do the payments align with my actual deposit cadence?
