How it is calculated
Fee amount = invoice amount × rate per 30 days ÷ 100 × actual days ÷ 30. Unlike a fixed deal fee, here the rate is set for a standard period (usually 30 days) and scales in proportion to how many days actually pass before the buyer pays.
This fee structure is cheaper for the client when the buyer pays quickly and more expensive when payment is delayed — unlike a fixed fee, which doesn't change whether the buyer paid on day 5 or day 60.
If your factoring contract charges a single flat fee on the invoice amount regardless of timing, use the separate factoring cost calculator instead — it's simpler and matches that payment structure more precisely.
