Your broker quoted a 1.4 factor rate on a $50,000 advance and skipped past the part where you ask what the APR is. There's a reason for that. The same advance, expressed as an annual percentage rate, lands somewhere north of 80%. Nobody is signing an 80% APR contract on purpose. The factor rate framing is what gets the deal across the table.
What a factor rate actually means
A factor rate is a multiplier. You take the advance amount and multiply by the factor to get the total payback. $50,000 at 1.4 means you owe $70,000 back. The $20,000 difference is what the lender keeps. There's no interest accruing, no balance shrinking against a quoted rate, no amortization schedule. It's a fixed dollar amount you owe from day one.
That structure is what lenders point to when they tell you the deal is simple. In a way it is. There's no rate that resets, no penalty interest, no late-payment APR. Just a number you owe and a daily debit pulling against it. The simplicity is also the problem.
Why factor rate is not an interest rate
Calling it a factor rate instead of an interest rate is a legal choice, not an accounting one. Interest rates trigger usury laws in most states, which cap how much a lender can charge. Interest rates also trigger Truth in Lending disclosures, which require a lender to quote you an APR before you sign.
An MCA structured as a purchase of future receivables sidesteps both. The lender isn't lending you money, technically. They're buying the rights to a portion of your future sales at a discount. That distinction is what keeps factor rates of 1.3, 1.4, 1.5 legal in states where the equivalent APR would be criminal usury. It's also why no MCA agreement you've signed includes an APR figure on the front page.
Converting factor rate to APR
The math is not complicated, but no broker will run it for you. Take the example. $50,000 advance, 1.4 factor, $70,000 total payback, repaid over nine months at roughly $370 a day across 21 business days a month.
The cost of capital is $20,000. You held that money for nine months, but you didn't hold all of it the whole time. Your balance dropped every day as the lender pulled debits, so on average you had access to about half the original advance. Twenty thousand dollars to borrow an average of twenty-five thousand over nine months annualizes to an APR comfortably above 80%. On a tighter term it can clear 100%.
The shortcut most analysts use: take the cost of capital (the factor minus 1), double it to account for the declining balance, then divide by the term in years. A 1.4 factor over 9 months runs 0.4 times 2 divided by 0.75, which lands above 100%. A 1.3 factor over 4 months runs 0.3 times 2 divided by 0.33, which clears 180%. Tighter terms make the APR uglier even when the factor rate sounds tame.
What happens when the term shifts
The factor rate looks fixed. The APR is not. If your business slows down and the daily debit grinds out the payback over 12 months instead of 9, the factor rate is still 1.4 and the total payback is still $70,000. The APR drops, because you held the money longer for the same total cost. That part rarely happens in practice, because most lenders keep the daily amount fixed regardless of revenue, so the term collapses inward instead of stretching out.
The reverse is what catches business owners. Some lenders shorten the effective term by pulling debits twice a day, or by adding true-up charges when revenue ticks up. Same factor rate on paper, higher APR in practice. The borrower never sees the second number because the contract doesn't carry it.
Stacking compounds the damage. Two MCAs running together at 1.4 each, with staggered terms, can carry a blended effective APR no responsible underwriter would attach to a credit line. The factor rate framing keeps that math out of view on every advance you sign.
What to do if you're already in one
Run the conversion. Take your original advance, your factor rate, and the term as it's actually playing out, not the term in the agreement. Calculate what you've paid, what you've borrowed, and how long you've held the money. The APR you compute is the number to benchmark against any refinance offer that comes in. If a consolidation broker is pitching a "lower" factor rate on a longer term, run that math too. The factor often goes down while the APR goes up.
If the lender has pulled past the payback total, that's an overcharge worth disputing in writing. If the daily debits don't match the contracted holdback against your current revenue, that's a reconciliation request worth filing. Both conversations work better when you can put a real APR figure on the table.
The factor rate is what makes the deal sound cheap. The APR is what the deal actually cost.
