A factor rate is a flat multiplier applied to the amount you borrow to set your total repayment. A 1.25 factor on $10,000 means you repay $12,500, which is roughly 63% to 75% APR if you repay over about eight months. Because the multiplier ignores how fast the balance falls, the true annual cost depends on how long you take to repay.
What Is a Factor Rate, and How Is It Calculated? #
A factor rate is a decimal, usually between about 1.1 and 1.5, that a funding provider multiplies by the amount you receive. The result is the total you agree to repay.
The formula is simple:
Amount received × factor rate = total repayment
For example, a $10,000 advance at a 1.25 factor requires $12,500 in total repayment. The cost of the money is the difference: $2,500. On an eight-month term, that 1.25 factor works out to roughly 63% to 75% APR, depending on the method used (see the next section). The $2,500 is fixed at signing. Paying early does not always reduce it, depending on the contract, and a longer term does not increase it either.
Many factor-rate products are repaid through daily or weekly deductions from business revenue, not monthly bills. That structure matters for cash flow, but it does not change the arithmetic of the multiplier.
How Do You Convert a Factor Rate to an APR-Equivalent? #
A factor rate is not an interest rate, so you cannot compare it directly with a loan's APR. You need to convert it. Here is the method, using the example above.
- Find the dollar cost. $12,500 repaid minus $10,000 received = $2,500.
- Express the cost as a share of the amount received. $2,500 ÷ $10,000 = 25%.
- Convert the repayment period to years. Eight months is 8 ÷ 12 = 0.67 years.
- Annualize the cost. 25% ÷ 0.67 = 37.5% on the full amount, treated as if you owed $10,000 the whole time.
That 37.5% figure understates the true cost, because you do not keep the full $10,000 for eight months. Your balance falls with every payment, so the average amount you owe is closer to half. Two ways of accounting for that give you the range:
- Average-balance method. Divide the $2,500 cost by the average balance over the term (about $5,000), then annualize. That gives roughly 75% APR.
- Amortized-schedule method. Build a standard payment schedule where equal payments of $1,562.50 each month retire the $12,500 over eight months. Solving for the monthly rate that makes those payments worth $10,000 today gives about 5.25% per month, or roughly 63% APR.
So a 1.25 factor over eight months works out to about 63% to 75% APR, depending on method. Either way, it is far above the cost of most bank loans. Use the same method every time you compare offers, and ask the provider which one it used.
The same amortized-schedule method gives a sense of the wider range. For example, a 1.10 factor repaid over six months comes to roughly 34% APR, and a 1.50 factor repaid over twelve months comes to roughly 80% APR. The factor looks similar in both cases only at first glance; the term and the method change the answer.
Why Does Repayment Speed Change the True Cost? #
The factor rate stays the same whether you repay in four months or twelve. The APR-equivalent does not.
Take the same 1.25 factor on $10,000 and compare two repayment periods, using the simple full-principal method from above:
- Over 4 months: $2,500 ÷ $10,000 = 25%, annualized over 0.33 years = about 75%.
- Over 12 months: $2,500 ÷ $10,000 = 25%, annualized over 1 year = 25%.
The dollar cost is identical. The annual cost is three times higher on the faster schedule. This is why a factor-rate advance can look inexpensive on paper and become expensive when a business repays quickly, for example after a seasonal surge in sales that shortens the payoff.
The reverse also holds. If your revenue slows and the repayment stretches out, the annualized cost falls, but the total dollars you pay do not. Plan for the total, and treat the APR-equivalent as a way to compare, not as a promise.
How Does a Factor Rate Differ from an Interest Rate and APR? #
Interest rate is the annual percentage charged on the outstanding balance. Each payment covers interest first, then principal, so the balance declines on a predictable schedule.
APR (annual percentage rate) expresses the total cost of borrowing, including most fees, as an annual figure. It lets you compare loans with different terms and fee structures on one scale.
Factor rate is a flat multiplier on the original amount. It does not reference a balance, a schedule, or a year. That is why it cannot be read as an interest rate. A "1.25" does not mean 25% per year, and presenting it that way understates what you pay.
The rule for any offer is this: if the provider quotes a factor rate, ask for the term, convert it to an APR-equivalent using a stated method, and compare that number with the APRs of other offers.
How Do the Costs Compare Side by Side? #
The table below compares categories of funding, not individual lenders. Costs vary with credit, time in business, revenue, collateral and market conditions, so treat these as general patterns rather than quotes. Where a factor rate appears, the APR-equivalent is shown beside it, using the amortized-schedule method and the example terms noted.
| Option | Typical cost | Speed | What it needs |
|---|---|---|---|
| Bank term loan | Interest-rate pricing; APR generally lower than factor-rate equivalents for well-qualified borrowers | Often several weeks; can be longer | Time in business, solid credit, financial statements, often collateral or a personal guarantee |
| SBA 7(a) loan | Variable or fixed rate set by a benchmark plus a spread capped by SBA rules; generally among the lower-cost options | Commonly one to three months | Eligible small business, strong documentation, personal guarantee, collateral in many cases |
| Business line of credit | Interest on the amount drawn only; APR varies with credit profile and lender | Can be quick once approved; approval may take weeks | Revenue history, credit review, sometimes a personal guarantee |
| Merchant cash advance (factor-rate product) | Factor rate, commonly about 1.1 to 1.5. For example, 1.10 over six months ≈ 34% APR; 1.25 over eight months ≈ 63% APR; 1.50 over twelve months ≈ 80% APR | Often within days | Steady card or bank-deposit revenue, shorter time-in-business requirements |
| Revenue-based financing | Fixed fee or multiple of funds, repaid as a share of monthly revenue; APR-equivalent depends on repayment speed | Often within days to a few weeks | Consistent revenue, bank account history, usually no hard collateral |
Two patterns stand out. Bank and SBA products usually cost less per dollar but take longer and ask for more. Factor-rate and revenue-based products move fast and ask for less, and they charge for that speed.
When Is a Bank, SBA Loan or Line of Credit the Right Tool? #
A factor-rate advance is a tool for a specific problem: a short, clearly defined need, a fast decision, and enough revenue to repay quickly without strain. It is often the wrong tool for anything else.
A bank term loan or SBA 7(a) loan is usually the better choice when:
- You need a large sum for equipment, real estate, or a major expansion.
- You can wait several weeks, and the timing does not cost you a lost opportunity.
- Your credit, time in business and documentation qualify you.
- You want a long repayment period and a lower monthly burden.
A business line of credit is usually the better choice when:
- Your cash needs are recurring or unpredictable, such as payroll gaps or inventory cycles.
- You want to borrow only what you use and pay interest only on the drawn balance.
- You can keep the line open before you need it.
A factor-rate product may still be sensible when the need is urgent, the payoff is clear, and you can repay quickly from known revenue. Run the APR-equivalent first. If the number makes sense for the return you expect, proceed. If it does not, a slower product may cost you less even after the wait.
When Does a Factor-Rate Advance Fit, and When Doesn't It? #
A factor-rate advance fits when speed matters more than cost, the amount is modest, and repayment from revenue is reliable. It does not fit when you can wait for a cheaper product, when the repayment period is likely to be long, or when you cannot absorb daily or weekly deductions.
Before you decide, convert the factor rate to an APR-equivalent, compare it with at least one bank or SBA quote, and write down the total dollars you will repay.
