The True Cost of a Merchant Cash Advance — and How to Calculate It Yourself

When you take a merchant cash advance, you are rarely quoted an interest rate. Instead you are quoted a factor rate — a flat multiplier applied to the amount advanced. A factor rate of 1.40 on a $50,000 advance means you repay $70,000, full stop, regardless of how quickly you pay it back.

That framing is not an accident. A factor rate makes an advance look far cheaper than the equivalent loan, because our instincts are calibrated to annual interest rates. "Forty percent more" sounds reasonable. Expressed as an annualized rate on a fast repayment schedule, that same advance can carry an effective cost well into the triple digits.

Factor rate versus interest rate

The critical difference is time. Interest accrues over the life of a loan, so paying it off early saves you money. A factor rate is fixed at signing — the total payback does not shrink if you repay faster. In fact, faster repayment makes the effective annualized cost higher, because you are paying the same premium over a shorter window.

Doing the math

Start with three numbers: the amount advanced, the factor rate, and the expected repayment term in days. Suppose you take $50,000 at a 1.40 factor rate, repaid daily over roughly 180 business days.

• Total payback: $50,000 × 1.40 = $70,000
• Total fee: $70,000 − $50,000 = $20,000
• Term: about 9 months of business days
• Effective annualized rate: roughly $20,000 / $50,000 = 40% over 9 months, which annualizes to well over 50% — and climbs sharply if the term is shorter.

The tool below does this for you. Enter your own numbers to see the total payback, the fee, and an approximate annualized cost.

Why the annualized number matters

You cannot make a good decision about refinancing, consolidating, or simply keeping an advance without knowing its true cost relative to your other options. A line of credit at 18% and an advance at an effective 60% are not close — but on the surface, the advance's factor rate of 1.30 can look tame.

The factor rate is the sticker. The annualized cost is the price.

Once you can translate every advance you hold into a single comparable figure, the picture usually clarifies quickly. Often it reveals which advance is doing the most damage — and that is the one to address first.
