How Invoice Factoring Costs Are Calculated

A factor advances a percentage of your invoice upfront and holds the rest as a reserve, releasing it (minus their fee) once your customer pays.

Upfront Advance = Invoice Face Value × Advance Rate %
Reserve = Invoice Face Value − Upfront Advance
Factoring Fee = Invoice Face Value × Fee Rate % × Number of 30-Day Periods Elapsed (tiered) or × Fee Rate % once (flat)
Total Net Proceeds = Invoice Face Value − Factoring Fee

Non-recourse factoring, where the factor absorbs non-payment risk, typically adds 0.5%–1.5% per month to the fee compared to recourse factoring. Because fees are charged per 30-day cycle rather than annualized, a 2% fee on a 30-day invoice is roughly equivalent to a 24% annualized rate.

Operational Guide

How to Use the Invoice Factoring Cost Calculator

1

Enter Invoice Face Value

The full dollar amount of the invoice you want to factor.

2

Set the Advance Rate

The percentage the factor pays you upfront — typically 70%–95%, most commonly 80%–90%.

3

Set the Factoring Fee Rate

The fee charged per 30-day period, typically 1%–5%.

4

Enter Estimated Days Until Paid

How long you expect your customer to take to pay the invoice.

5

Choose Fee Structure & Recourse Type

Flat charges the fee once; tiered charges it per elapsed 30-day period. Non-recourse costs more but shifts non-payment risk to the factor.

Real-World Scenario Example

"A business factors a $25,000 invoice at an 85% advance rate with a 2.5% factoring fee per 30-day period, expecting payment in 30 days, recourse factoring."

Inputs

invoiceFaceValue:25000
advanceRatePercent:85
factoringFeeRate:2.5
daysUntilPaid:30

Result

Upfront Advance = $21,250, Factoring Fee = $625, Reserve Release = $3,125, Total Net Proceeds = $24,375 — an annualized equivalent rate of about 30.4%.
