Invoice Factoring Cost Calculator

Price an invoice-finance offer: advance rate, discount fee, service fee and what it costs against waiting or a loan. The result updates as you type so you can compare scenarios quickly.

The method

How it is worked out

Cost = advance × discount rate × days ÷ 365 + invoice × service fee + fixed fees
advance
Invoice × advance rate, paid up front
discount rate
Annual rate charged on the advance while outstanding

Keep in mind

What it leaves out

  • RecourseWith recourse you repay if the customer defaults.
  • Minimum periodsSome facilities charge a minimum number of days.
  • Whole-turnover dealsSelective factoring costs more per invoice than a whole-ledger facility.

Use the calculator to compare scenarios rather than as a guaranteed forecast.

How it works and an example to tryShow less

How to use the result

The advance is the invoice times the advance rate. The discount charge is the advance times the annual discount rate, pro-rated for the days outstanding. The service fee is a percentage of the invoice. Total cost is annualised and compared with your gross profit on the invoice.

Example to try

A £50,000 invoice with an 85% advance, 9% discount rate over 60 days and a 1.5% service fee costs about £1,380: 2.8% of the invoice, an annualised 19%, and 9% of a 30% gross margin.
