What could you add to the unpaid invoice?
On a qualifying business debt, you may be able to claim interest and compensation as well as the original invoice balance. Your contract and the circumstances still need to be checked.
The calculation starts with the unpaid principal, including VAT where it forms part of the debt.
For qualifying business debts, statutory interest is normally 8% above the applicable Bank of England base rate. The applicable rate is determined by reference to when the specific debt became due, rather than simply using the rate in force on the day you run the calculation. Older invoices may therefore require a different historical Bank Rate from more recent invoices. Enter the relevant Bank Rate and the calculator automatically adds 8%.
The fixed sum is calculated separately for each qualifying late invoice or payment, based on its value:
- Debt below £1,000
- £40
- Debt from £1,000 to £9,999.99
- £70
- Debt of £10,000 or more
- £100
It is not normally one charge for the whole customer account or calculator batch. Each invoice must independently qualify.
Reasonable additional recovery costs may be relevant in some cases, but they should be evidenced and reviewed before being claimed.
Make sure you are entitled to claim it
The calculation may be accurate but the claim can still be wrong. Check the due date, customer type, contract and applicable rate before adding these sums to a demand.

How should you use the calculation?
You might use the figures in a payment request or formal demand, but the right next step depends on the evidence, any dispute, the debtor’s position and whether escalation is commercially sensible.
