How to Convert a Factor Rate to APR in 2026

Factor rates (used for MCAs and revenue-based financing) and APRs (used for amortizing loans) measure cost differently. Converting factor rate to APR-equivalent is essential to apples-to-apples compare financing options.

Steps

  1. Calculate the total finance cost Multiply the advance amount by the factor rate, then subtract the advance amount. Example: $50,000 advance × 1.30 factor rate = $65,000 total payback. Finance cost = $65,000 - $50,000 = $15,000.
  2. Determine the term length in days MCA terms are typically 4-18 months. Convert to days: 9 months × 30 days = 270 days. Use actual term, not the contractual maximum, because some MCAs pay off faster if revenue is strong.
  3. Apply the APR conversion formula APR ≈ ((Factor Rate - 1) × 365) / Term in Days. Example: ((1.30 - 1) × 365) / 270 = (0.30 × 365) / 270 = 109.5 / 270 = ~40% APR-equivalent. Shorter terms produce dramatically higher APR-equivalent figures for the same factor rate.
  4. Compare to amortizing loan options If a term loan is available at meaningfully lower APR (say 12-18% for a quality SBA-tier borrower vs 40% MCA APR-equivalent), the term loan is usually the better economic choice. MCAs make sense when speed of funding (24-72 hours vs 45+ days for SBA) is essential.

Frequently asked questions

Is factor rate the same as interest rate?

No. Factor rate is a fixed multiplier — total payback is set at the time of funding regardless of how fast you repay. Interest rate (APR) is annualized — paying off early reduces total interest. The two measure different things; APR-equivalent conversion lets you compare.

Why is the APR-equivalent so much higher than the factor rate suggests?

Because MCAs typically have short terms (6-18 months) while the factor rate looks like a tame number (e.g., 1.30 'only 30%'). Spreading the 30% finance cost over 9 months annualizes to ~40% APR. The shorter the MCA term, the higher the APR-equivalent.
