Rate Indexes / Invoice Finance
Invoice finance pricing is structured differently from loan APRs. Lenders typically charge a service fee (percentage of turnover processed through the facility) plus a discount charge (interest on funds drawn, based on base rate or SONIA plus a margin). This index shows typical ranges for both components from Spark Finance's lender panel.

How much does invoice finance cost in the UK?
Invoice finance typically has two cost components: a service fee (0.5-2.5% of invoice value processed) and a discount charge (interest on funds drawn, typically SONIA plus 2-6% per annum). For a business turning over £1m with a typical SME facility, total annual cost might be £8,000 to £25,000 depending on how much of the facility is drawn. This should be weighed against the working capital benefit of receiving 70-90% of invoice value upfront.
What is the difference between factoring and invoice discounting rates?
Factoring (where the lender manages your credit control) and invoice discounting (where you retain credit control) are typically priced similarly, but the service fee for factoring may be slightly higher to account for the credit control service. The key difference is confidentiality: discounting is not disclosed to your customers. Your customers know about factoring as they are directed to pay the lender directly.
Can startups access invoice finance?
Some invoice finance providers will consider businesses with as little as 3-6 months trading history if there are good quality invoices from creditworthy customers. The minimum turnover threshold varies by lender. Spark Finance works with specialist providers who can accommodate newer businesses where others cannot.
Invoice finance pricing data is compiled from facility proposals received through the Spark Finance broker panel. Fee and discount charge ranges represent the 10th and 90th percentile of initial proposals. SONIA rate as at June 2026 should be added to discount charge margins to calculate approximate total cost. Data updated quarterly.
