Effective APR on MCAs explained (and why it is not what they tell you)
Factor rate is the most successful piece of financial product framing in the last 20 years. It takes a borrowing cost that would be illegal in most consumer contexts and presents it as a small multiplier that sounds reasonable. A 1.45 factor sounds like 45 percent. The real annualized cost is usually 90 to 200 percent depending on the term, and the gap between the two is where the MCA industry makes its money. This article shows you how to calculate the real number on your own contracts and why doing so changes every conversation you have with a lender.
TL;DR
- Factor rate and APR are not the same thing. A 1.45 factor over 6 months has an effective APR around 132 percent.
- The shorter the term, the higher the effective APR for the same factor rate. Daily repayment compounds the cost.
- A 1.30 factor over 12 months on $50K produces an effective APR around 50 percent. Still high.
- A 1.45 factor over 6 months on $100K produces an effective APR around 132 percent.
- Calculating effective APR matters because lenders settle more aggressively when unconscionability is in play.
- Owners who calculate the real number once almost never sign another MCA.
Why factor rate hides the real cost
MCAs are sold on factor rate because factor rate is a simple multiplier that does not account for the time value of money. APR is a standardized borrowing cost that does. The two answer different questions, and only APR answers the question that matters: how much is this capital actually costing me on an annualized basis.
A factor rate of 1.45 looks like 45 percent. The salesperson presents it that way. They will sometimes say "45 percent over the term" and compare it to a credit card. Both framings are misleading. The factor rate does not account for the daily repayment cadence. As you pay back the principal, the lender is not earning the factor rate on the full balance for the full term. They are earning it on a declining balance over a short term. To replicate the actual yield in APR terms, you have to amortize the daily payment stream against the original funded amount.
The result is almost always materially higher than the factor rate suggests. The shorter the term, the bigger the gap. The faster the daily debit, the bigger the gap.
How to convert factor rate to effective APR
The basic math takes four inputs. Funded amount (purchase price). Total payback (purchased amount). Term in days. Daily debit amount. With those four numbers, you can amortize the daily payment stream against the funded amount and back out the implied annual rate.
The formula is iterative because it is solving for the rate that makes the present value of the daily payments equal the funded amount. In practice, most owners use a calculator or spreadsheet rather than doing the math by hand. The output is the effective APR.
A useful rule of thumb: for a typical MCA with daily debits over a 6 to 12 month term, the effective APR is roughly the factor rate cost (factor minus 1) divided by the average term in years, multiplied by 1.5 to 2x. So a 1.45 factor over 6 months has a factor cost of 45 percent on a 0.5 year term. That is 90 percent annualized linearly, and the daily repayment compounds it to roughly 130 percent. The shorter the term, the more the rule-of-thumb adjustment goes up.
Worked example one: 1.45 factor on a 6 month MCA
A merchant takes a $100,000 MCA at a 1.45 factor over a 6 month estimated term. Total payback is $145,000. Daily debits are roughly $1,200 over 22 business days a month for 6 months.
Amortize that daily payment stream against the original $100,000 funded amount. The implied APR comes in around 130 to 135 percent depending on the exact daily cadence and weekend handling. The 45 percent factor cost translates to roughly 132 percent annualized once the daily repayment is amortized.
That is the real number. If a bank quoted you a loan at 132 percent APR, you would walk out of the office. The MCA equivalent is sold daily because the factor rate framing makes the same number look reasonable.
Worked example two: 1.30 factor on a 12 month MCA
A merchant takes a $50,000 MCA at a 1.30 factor over a 12 month estimated term. Total payback is $65,000. Daily debits are roughly $250 over 22 business days a month for 12 months.
Amortize that against the original $50,000. The implied APR comes in around 50 percent. The 30 percent factor cost translates to roughly 50 percent annualized because the term is twice as long and the daily repayment is concentrated less aggressively.
50 percent APR is still high, well above what a bank line or SBA loan would charge, but it is in a different category than the 132 percent example. The factor rate of 1.30 is in a band where some MCAs are at least defensible as bridge financing for short cash flow gaps. The factor rate of 1.45 over 6 months is in a band where the contract is very expensive money under any framing.
Why daily debits compound the cost
The reason effective APR runs above the linear annualized factor cost is that the daily repayment cadence concentrates the payback against the early portion of the funded period. By month two of a 6 month MCA, you have already returned a third of the principal. The lender is not earning the factor rate on the full $100,000 for 6 months. They are earning it on a balance that drops to zero over the period. To produce the same total dollar profit on a smaller average outstanding balance, the implied yield has to be higher.
The same dynamic does not happen with traditional loans because traditional loans amortize on a monthly schedule and the calculation is built into the disclosed APR. The MCA industry uses factor rate because the daily cadence makes the equivalent APR look bad, and the factor rate framing avoids that disclosure.
Why this changes the negotiation
Calculating the effective APR matters in two ways. First, it changes how lenders respond to settlement negotiations. Effective APRs above 100 percent in jurisdictions where usury is even loosely enforced create real legal exposure for the lender. A merchant who can recite the effective APR on each contract is signaling that the firm representing them knows what it is doing. Lenders that recognize that signal settle faster and at better numbers.
Second, it changes the merchant's own decision-making for future financing. Owners who have calculated the conversion once on their own contracts almost never sign another MCA. The number is too uncomfortable to pretend it does not exist. That clarity is half the battle in breaking the stacking cycle.
What to do next
Pull your active MCA contracts. Find the purchase price (funded amount) and the purchased amount (total payback) on each. Note the term and the daily debit. Run them through our free APR calculator or upload the contracts to our review tool. The number that comes out is what your capital is actually costing you, and seeing it on each contract changes how the rest of the conversation goes. Most merchants are surprised, and a few are upset. Both responses are appropriate.
