One of the biggest challenges with merchant cash advances is understanding the true cost. Unlike a traditional loan with an interest rate and clear APR disclosure, MCAs use factor rates — and many business owners sign agreements without understanding what they are actually paying.
The basic calculation: Total Payback = Advance Amount multiplied by Factor Rate. Example: $50,000 advance with a 1.30 factor rate means you pay back $65,000 total. Your total cost of capital is $15,000.
But this basic number does not tell the full story. To properly compare an MCA with other financing, you need to calculate the effective APR. The formula: Effective APR = (Cost of Capital divided by Advance Amount) divided by (Term in Months divided by 12) multiplied by 100.
Example: $50,000 advance, 1.30 factor rate, 6-month term. Cost = $15,000. Effective APR = ($15,000 / $50,000) / (6/12) x 100 = 60 percent. The same advance over 4 months: ($15,000 / $50,000) / (4/12) x 100 = 90 percent. Shorter terms dramatically increase the effective APR even though the total dollar cost is the same.
Daily payment calculation: Total Payback divided by (Term in Months multiplied by 22 business days). For the $65,000 payback over 6 months: $65,000 / 132 business days = $492 per day. Over 4 months: $65,000 / 88 business days = $739 per day.
Daily payment as a percentage of revenue: this is the most important number most business owners never calculate. If your daily revenue averages $3,000 and your MCA payment is $500, that is 16.7 percent of daily revenue going to MCA repayment. Financial advisors recommend keeping this below 15 percent. Above 20 percent creates significant cash flow pressure.
How to use these calculations when comparing offers: calculate the total payback for each offer, the effective APR for each offer, the daily payment for each offer, and the daily payment as a percentage of your average daily revenue. The offer with the lowest total payback is not always the best — a slightly higher payback with a longer term might result in a manageable daily payment versus one that crushes your cash flow.
