What Is a Factor Rate? An Honest Explainer

Factor rate vs. interest rate, the key difference

Most business funding is priced with an interest rate or APR, bank term loans, SBA loans, lines of credit, equipment financing. A handful of revenue-based products (revenue-based financing and merchant cash advances) are priced with a factor rate instead. If you're weighing a factor-rate offer against an interest-rate one, understanding the difference is the whole game.

An interest rate is time-based. You borrow $100, pay 10% interest per year, and after one year you owe $110. If you pay it back in six months, you owe ~$105.

A factor rate is NOT time-based. It is a simple multiplier applied once at the time the advance is issued. You receive $100 with a 1.30 factor rate. Your total repayment is fixed at $130 ($100 × 1.30). It doesn't matter if you pay it back in 30 days or 365 days, you always owe $130. The factor rate does not compound over time or accrue daily interest like a traditional loan.

How to calculate your total repayment

The formula is simple: Advance Amount × Factor Rate = Total Repayment.

Example: You receive a $50,000 advance with a 1.35 factor rate. Your total repayment is $50,000 × 1.35 = $67,500. You will repay $67,500 total, no matter how long it takes. If your funder takes 10% of daily revenue ($500/day on $5,000/day sales), you'll pay off the $67,500 in approximately 135 days (4.5 months). If your revenue spikes and you repay faster, you still owe exactly $67,500, there's no prepayment penalty or discount for early repayment.

Worked example: $50,000 at 1.35 vs the same $50,000 at 1.25

Numbers make this concrete. Say two funders each offer you a $50,000 advance with an estimated 9-month (roughly 270-day) repayment, and the only difference is the factor rate.

Offer A, 1.35 factor rate. Principal: $50,000. Total repayment: $50,000 × 1.35 = $67,500. Cost of capital: $17,500. Spread over about 190 business days of remittance, that is roughly $355 per business day. Using the APR formula below, the estimated APR equivalent is 0.35 × (365 ÷ 270) = about 47%.

Offer B, 1.25 factor rate. Principal: $50,000. Total repayment: $50,000 × 1.25 = $62,500. Cost of capital: $12,500. Daily remittance over the same schedule: roughly $329 per business day. Estimated APR equivalent: 0.25 × (365 ÷ 270) = about 34%.

Same money, same term, and Offer B costs $5,000 less. That is the entire argument for comparing multiple structured offers instead of signing the first approval: a tenth of a point on the factor rate is real dollars, not a rounding error. On a $100,000 advance the same gap doubles to $10,000.

Both examples are illustrative. Your actual daily payment depends on the remittance schedule in your agreement, and every offer you compare should state all five numbers in writing: principal, factor rate, total repayment, daily or weekly payment, and estimated APR.

Same factor rate, different term: the hidden variable

Because a factor rate is a fixed multiplier, the repayment term quietly controls what the money really costs per year. A 1.25 factor rate repaid over 12 months works out to roughly a 25% APR equivalent. The identical 1.25 repaid over 6 months doubles that to roughly 51%, and over 4 months it climbs past 75%. The fee never changed, $12,500 on $50,000, but the time you held the capital did.

This cuts both ways. A shorter term means a higher effective annual cost but less total time carrying daily payments; a longer term is gentler on cash flow but ties up remittances for months. When two offers show the same factor rate, the one with the longer estimated term is the cheaper money on an annualized basis.

So never compare factor rates in isolation. Ask every funder for the estimated repayment term in writing, then run the APR conversion on each offer. Two offers that look identical at 1.30 can be 20 annualized points apart.

Early payoff, prepayment discounts, and renewal traps

With interest-rate financing, paying early saves money. With a plain factor-rate agreement it usually does not: the fee is fixed the moment you sign, so retiring $67,500 in 4 months instead of 9 just means you paid the same $17,500 for less time with the capital, which pushes your effective APR up, not down.

Two things to look for. First, prepayment discount addendums: some funders will contractually reduce the total payback if you retire the balance inside a stated window, for example 30 or 90 days. If early payoff is realistic for you, ask for the discount schedule in writing before signing; it can meaningfully change which offer wins.

Second, renewals. If you take a second advance before the first is fully repaid, many funders deduct the old remaining balance from the new advance while charging the full new factor rate on the full new amount. You end up paying a fee on money you never received. If you expect to need capital again mid-term, say so up front and have the renewal math shown to you in dollars before you commit to the first agreement.

How to estimate APR from a factor rate

APR (Annual Percentage Rate) is calculated by converting the factor rate into an annualized percentage. The formula is: APR = (Factor Rate − 1) × (365 ÷ Repayment Days) × 100.

Example: $50,000 advance, 1.35 factor rate, expected 135-day repayment. Fee = $67,500 − $50,000 = $17,500. APR = ($17,500 ÷ $50,000) × (365 ÷ 135) × 100 = 0.35 × 2.70 × 100 = ~94.5% APR.

However, this APR is an ESTIMATE. The actual APR depends on how fast you actually repay. If your revenue drops and you take 200 days to repay, the effective APR falls to ~64%. If your revenue booms and you pay off in 60 days, the effective APR rises to ~213%. This is why the effective APR on factor-rate financing varies widely, the stated APR assumes an average repayment term that may not match your business reality.

What a 'good' factor rate looks like

Industry-standard factor rates range from 1.15 to 1.50, depending on your credit profile and business strength.

For a business with 2+ years of history, 650+ credit score, and $50K+/month revenue: expect 1.15-1.25.

For a business with 1-2 years of history, 600-649 credit score, $20-50K/month revenue: expect 1.25-1.35.

For a newer business (6-12 months), 550-599 credit score, or $10-20K/month revenue: expect 1.35-1.50.

Rates above 1.50 are rare and usually indicate very high-risk applications or micro-advances. Rates below 1.15 are also rare, if a funder is offering 1.10 or lower, verify they're legitimate and understand their underwriting.

Questions to ask before signing

What is the exact factor rate? (Not a range, a specific number.) What is my total repayment amount in dollars? What will my daily or weekly payment be? How many days or months do you estimate I'll take to repay? Are there any additional fees beyond the factor rate (origination, processing, prepayment penalties, ACH fees)? Can I prepay early without penalty? What happens if my revenue drops and I can't make my payment?

If a lender can't answer these questions clearly and in writing before you sign, do not proceed.
