Invoice Factoring Rates

Invoice factoring rates are not a single percentage, and comparing providers on one headline figure will usually lead you to the wrong decision. The total cost of a factoring facility comes from several components, some of which are easy to overlook until you are already committed to a contract.

This article explains how factoring fees are structured, what affects the rate you are quoted, and what the total cost typically looks like for an SME — including a worked example that puts the numbers in context.

How invoice factoring fees are structured

Most factoring facilities are priced across two main components.

The service fee

The service fee (sometimes called the administration fee) covers the factoring company's work in managing your sales ledger, chasing payments, and running credit checks on your customers. It is charged as a percentage of your total gross invoice value, typically between 0.75% and 3%. The exact figure depends on your turnover, invoice volume, and the complexity of your ledger.

The discount rate

The discount rate is the interest charged on the funds you actually draw down. It is usually quoted as the Bank of England base rate plus a set margin — for example, base rate plus 2% to 3.5%. The charge applies only to the amount drawn and only for the number of days it is outstanding, so it works more like an overdraft than a fixed-term loan.

Together, these two components make up the bulk of the cost. The service fee is ongoing regardless of how much you draw; the discount charge varies with your usage.

What affects the rate you are quoted

Factoring providers price based on risk and workload. The main factors are:

• Annual turnover. Higher-turnover businesses typically attract lower percentage fees. The economics improve at scale, and larger clients carry more negotiating leverage.

• Customer credit quality. If your customers are large, established businesses with strong payment histories, lenders view the invoices as lower risk and price accordingly. A ledger dominated by smaller or slower-paying clients will attract higher rates.

• Invoice volume and size. A business sending 800 small invoices a month requires more administrative work than one sending 15 large ones. Higher admin burden means a higher service fee.

• Industry sector. Some sectors carry higher rates due to perceived risk. Construction, for example, is often priced at a premium because of payment disputes and retentions.

• Length of relationship. Rates typically improve as you build a track record with the provider. A business that has held a clean facility for two years is in a much stronger position to renegotiate than a new customer.

Additional fees to look out for

Beyond the service fee and discount rate, some providers include charges that are easy to miss when comparing headline offers. Check any proposal carefully for:

• Arrangement fees. A one-off cost to set up the facility, ranging from a few hundred to a few thousand pounds depending on the provider.

• Audit fees. Periodic charges for the lender to review your sales ledger and verify the security behind their position. These are standard practice but vary in frequency and cost.

• Disbursement fees. Small per-transfer charges when funds are released to your account. Minor individually, but worth understanding if you draw down frequently.

• Termination fees. Potentially significant costs if you want to exit before the contract term ends. Always read the exit terms before signing. A facility that is cheap to enter but expensive to leave is a poor deal if your circumstances change.

What factoring actually costs

To see how the components add up, consider a business with £600,000 in annual turnover that consistently holds around £100,000 in outstanding invoices at any given time.

Using a service fee of 1.5% and an illustrative discount rate of 7.5% per annum on an average drawn balance of £80,000 (80% of the outstanding ledger):

• Service fee: 1.5% × £600,000 = £9,000 per year

• Discount charge: 7.5% × £80,000 = £6,000 per year

• Total annual cost: approximately £15,000 (around 2.5% of turnover)

These figures are illustrative — actual rates depend on the factors above. But the exercise is useful because it shows that the service fee and the discount charge can be broadly similar in size, and that comparing on just one of them gives an incomplete picture.

How to get a better rate

Factoring rates are not fixed, and there are several things you can do to improve your position:

• Get multiple quotes. Rates vary meaningfully between lenders. Approaching three or four providers and making clear you are comparing gives you genuine negotiating leverage.

• Improve your customer mix. A cleaner ledger with higher-quality debtors and fewer overdue accounts directly reduces the risk your lender is pricing. Better customers equal better rates.

• Review your rate as you grow. As your turnover increases and your payment record improves, push for a renegotiation. Providers value reliable, growing clients and will often reduce their fee rather than lose you to a competitor.

• Check minimum fees. Some facilities carry a minimum monthly charge regardless of activity. If you are seasonal, check whether that floor makes the facility expensive in your quieter months.

Frequently asked questions

Is invoice factoring more expensive than a bank loan?

The headline rate often appears higher, but the comparison is not straightforward. A bank loan provides a fixed amount of capital. A factoring facility provides a revolving credit line that scales with your turnover and includes credit management services. Whether the additional cost is justified depends on whether those services have value for your business.

Can I negotiate my factoring fees?

Yes. As your turnover grows and your payment record demonstrates reliability, you should review your rates regularly. Providers are willing to reduce fees to retain a growing client rather than lose them to a competitor.

Are invoice factoring rates higher than invoice discounting rates?

Typically yes, because the factoring provider is doing more work (managing your collections). If your business qualifies for discounting and you have your own credit control function, discounting is usually the lower-cost option.

What does "base rate plus margin" mean in practice?

Factoring discount rates are often quoted as the Bank of England base rate plus a fixed margin. When the base rate changes, your borrowing cost changes with it. Always check whether the margin is fixed for the term of the contract and whether there is a cap on the total rate.

How do I compare factoring quotes accurately?

Ask each provider for the same information: the service fee percentage, the discount rate, any minimum monthly fee, and a full list of ancillary charges. Then apply those figures to your own turnover and average debtor balance to calculate a comparable annual cost. Comparing on a single number will almost always lead to the wrong choice.
