How Much Does Invoice Discounting Cost?

Invoice discounting is typically cheaper than invoice factoring. The lender is doing less work: you manage your own credit control and chase your own customers for payment. The lender advances against your invoices without taking on your collections. That difference in workload shows up directly in the fees.

For most UK businesses using a discounting facility, the all-in annual cost runs between 1% and 3.5% of the value of invoices funded. In cash terms, a business with £1 million annual turnover and an average debtor balance of £100,000 would typically pay between £3,500 and £8,000 a year in total. Here is how that number is built and what moves it.

The two main cost components

Every discounting facility is priced across a discount rate and a service fee. Comparing on one figure alone will produce a misleading result.

The discount rate is the interest charge on the advance. It is calculated daily on the outstanding balance, like an overdraft, and is typically quoted as the Bank of England base rate plus a fixed margin. For a discounting facility, the all-in annualised rate generally falls between 1.5% and 3%, slightly lower than the equivalent factoring rate because the lender is not managing your collections.

The service fee covers the lender's administration. It is calculated as a percentage of your total monthly invoiced turnover and typically runs between 0.2% and 0.5% for discounting. This is the fee that most clearly distinguishes discounting from factoring. The equivalent factoring service fee ranges from 0.5% to 2.5%, reflecting the credit management work the lender takes on in that product.

What a discounting facility typically costs

Numbers make the components easier to judge.

Take a business with £1 million annual turnover invoicing monthly, with an average debtor balance of £100,000 and customers paying on 60-day terms:

• Discount rate at 2.5%: 2.5% per annum on £100,000 = £2,500 per year

• Service fee at 0.35% of turnover: 0.35% of £1,000,000 = £3,500 per year

• Total: £6,000 per year, or £500 per month

At the lower end of market rates for the same business:

• Discount rate at 1.5%: £1,500 per year

• Service fee at 0.2%: £2,000 per year

• Total: £3,500 per year, or around £290 per month

The gap between the best and worst quotes for the same business can be several thousand pounds a year, which is why comparing providers on a full fee breakdown matters rather than accepting the first quote you receive.

What affects your discounting quote

The main variables that move your rate up or down:

• Turnover volume: higher turnover generally attracts lower service fee percentages as the lender spreads fixed costs over more invoicing

• Customer creditworthiness: a clean ledger of well-rated clients is lower risk and typically attracts better terms

• Advance rate: drawing 90% of invoice value costs slightly more than drawing 80%

• Non-recourse protection: transferring bad debt risk to the lender adds 0.3% to 0.8% to the service fee

• Sector risk: sectors with higher bad debt exposure may be priced less favourably

• Minimum monthly fee: some lenders set a floor charge regardless of usage, and this has a bigger impact on cost in months where invoicing is lower

Discounting vs factoring on cost

Invoice discounting is consistently cheaper than factoring on headline fees. A business with £1 million turnover paying a 0.35% service fee for discounting pays £3,500 a year for that component. The equivalent factoring service fee at 1.2% is £12,000. That is a difference of £8,500 a year, before the discount rate is even factored in.

That said, discounting only makes financial sense if your business is absorbing the credit control function internally. If it requires you to hire a credit controller or significantly increase the time your team spends on collections, the real cost comparison narrows. Our guide to invoice discounting vs factoring covers the full comparison, including how to think about the operational cost of credit control when doing the maths.

How to compare discounting quotes properly

Ask every provider for a full written breakdown. The figures to compare are the discount rate, the service fee percentage, the minimum monthly fee, audit fees (lenders periodically verify the invoices you have assigned), and early termination penalties. Apply those figures to your own turnover and average debtor balance to produce a total annual cost you can compare like for like.

Frequently asked questions

Is invoice discounting cheaper than a bank overdraft?

It depends on usage. A bank overdraft only charges interest when drawn and has no service fee. A discounting facility charges a service fee on your full invoiced turnover whether or not you draw on the advance. For businesses that consistently run close to their borrowing limit, discounting often works out cheaper per pound advanced. For occasional or irregular use, an overdraft may cost less overall.

Does my turnover affect the rate I am quoted?

Yes. Higher turnover generally attracts a lower service fee percentage, because the lender is spreading its fixed administration costs across a larger volume of invoices. A business turning over £2 million will typically be quoted a lower service fee rate than one turning over £500,000 with the same lender, all else being equal.

Are invoice discounting fees tax-deductible?

Yes. Both the discount rate and the service fee are treated as business expenses and are deductible against corporation tax or income tax depending on your business structure. Your accountant can advise on how to classify the different components correctly in your accounts.

What is a minimum monthly fee and how does it affect the total cost?

Some lenders set a minimum monthly charge regardless of how much of the facility you use. If your invoicing is seasonal or irregular, this can significantly increase the effective cost during quieter months. Always ask for the minimum monthly fee figure and include it in your total annual cost calculation when comparing providers, as it is often not the number that leads a quote.
