Invoice Discounting Costs & Fees Explained
Market Invoice is an independent UK invoice finance comparison site that ranks 85 active UK lenders.
Invoice discounting costs two fees: a management fee of roughly 0.2-1% of the invoices you put through the facility (confidential facilities typically 0.3-0.5%), and a discount charge of 1.5-3% above the Bank of England base rate (3.75% since 18 March 2026) on the funds you draw. It is cheaper than factoring because you keep your own credit control. A £1.2m-turnover business drawing £85,000 typically pays £5,000-£12,000 a year all-in.

UK invoice discounting costs a management fee of 0.2-1% of invoice value put through the facility plus a discount charge of 1.5-3% above the Bank of England base rate (3.75% since 18 March 2026) on funds drawn. Formula: discount charge = funds in use x (base + margin) / 365 x days outstanding. More detail + scope
Summary
Invoice discounting is priced in two parts. The management fee (0.2-1% of turnover through the facility, lower than factoring's 0.5-3% because the business keeps its own credit control) and the discount charge (interest on drawn funds, typically 1.5-3% over base, accruing daily). Watch-outs: arrangement fees, annual audit fees, minimum monthly fees, CHAPS charges and termination fees. Confidential facilities run about 0.3-0.5% management fee and usually need £500k+ turnover.

The two core invoice discounting fees
Every UK invoice discounting facility is priced around the same two components. The management fee (some providers call it a service fee or administration fee) is a percentage of each invoice you notify to the facility. Because you keep running your own sales ledger and credit control, it is much lower than the equivalent factoring service charge: typically 0.2-1% of turnover against 0.5-3% for full factoring.
The discount charge is interest on the cash you actually draw, calculated daily on funds in use. UK providers price it as a margin over the Bank of England base rate, typically 1.5-3% over base. With base at 3.75% (since 18 March 2026), that means an effective annual rate of roughly 5.25-6.75% on drawn funds. You only pay it on what you draw: an unused facility accrues no discount charge, though minimum monthly fees may still apply.
Fee table: what each charge looks like in 2026
| Fee | Typical range | Charged on | Notes |
|---|---|---|---|
| Management fee | 0.2-1% of invoice value | Each invoice notified | Confidential facilities typically 0.3-0.5%; falls with turnover |
| Discount charge | 1.5-3% over base (3.75%) | Funds drawn, daily | Only on what you use; accrues until your customer pays |
| Arrangement fee | £500-£2,000 | Setup, one-off | Often negotiable or waived on larger facilities |
| Audit / survey fee | £500-£1,500 per audit | Annually or semi-annually | The provider's periodic check of your ledger and systems |
| Minimum monthly fee | £300-£1,000 | Quiet months | Floor on the management fee; test against your quietest quarter |
| CHAPS payment fee | £15-£25 per transfer | Same-day drawdowns | Free Faster Payments or BACS usually available |
| Termination fee | 1-3 months of average fees | Early exit | Check notice period; see our guide to exiting a facility cleanly |
The invoice discounting formula
Discount charge = funds in use x (base rate + margin) / 365 x days outstanding
Plus, separately: management fee = invoice value notified x management fee %
The discount charge behaves like overdraft interest: it accrues daily on your drawn balance and stops when your customer pays and the ledger clears. That means customer payment speed is the single biggest driver of your total cost. A ledger that pays in 30 days costs roughly half the discount charge of one that pays in 60 days, on the same drawn balance. To convert a quote into a comparable annual rate, use our APR equivalent calculator.
Worked example: £100,000 a month through a confidential facility
Take a business invoicing £100,000 a month (£1.2m a year) on a confidential invoice discounting facility with a 0.4% management fee, an 85% advance rate, a 2.5% margin over the 3.75% base rate (6.25% total), and customers paying in 45 days on average:
- Management fee: £100,000 x 0.4% = £400 a month, £4,800 a year.
- Average funds in use: £100,000 x 85% x (45/30) = £127,500 available; assume the business draws about £85,000 of it on average.
- Discount charge: £85,000 x 6.25% / 12 = about £443 a month, £5,313 a year.
- Total core cost: about £843 a month, £10,113 a year, before one-off arrangement and audit fees.
As a share of turnover that is about 0.84%. The same business on full factoring at a 1.5% service charge would pay £18,000 a year in service charge alone before interest. That gap is the discounting discount: you are doing the credit control work yourself. Project the full multi-year picture, including minimum fees and exit costs, with our lifetime cost calculator.
How to keep invoice discounting costs down
Rates fall with turnover, ledger quality and competition. Businesses putting £1m+ through a facility with creditworthy customers and low dispute rates get the bottom of the ranges above. Get at least three quotes and compare them line by line (our quote comparison guide shows exactly how), challenge the minimum monthly fee if your volumes are seasonal, and ask for the arrangement fee to be waived. If a provider's audit fee looks high, say so: it is one of the most quietly negotiable lines on the tariff.
Also sanity-check the product itself. If your service charge quote is creeping above 1%, you are being priced like a factoring client: read our factoring vs invoice discounting comparison and our generic invoice finance costs guide to see whether the structure fits.
