The math on a $60,000 invoice
Factoring wins on a fast-paying invoice and loses badly on a slow one.
Factoring: a $60,000 invoice at an 83% advance puts about $50,000 in your account now. A 3% factor fee is $1,800, so you net roughly $48,200 against the advance. If the customer pays in 30 days, that is about 3.6% for one month, which annualizes to roughly 43%.
Business loan: $50,000 at 12% APR over 12 months is about $4,442 a month, roughly $3,304 in total interest, and about $53,304 all in.
For a single invoice that clears in 30 days, $1,800 against $3,304 makes factoring look cheap. The trap is duration. If the customer takes 90 days, that same fee structure can run $5,400 or more on one invoice, and the loan would have been cheaper while also being reusable for the rest of the year.
