Invoice due date calculator, work out UK payment terms
Work out exactly when an invoice falls due: net 30, end of month, or any custom term, with the weekday and how many days it is already overdue.

How do I calculate an invoice due date?
Add the agreed payment term to the invoice date. An invoice dated 10 March on net 30 terms is due on 9 April.
What does end of month mean on an invoice?
The term runs from the last day of the invoice month. A 12 March invoice on end of month plus 30 days is due around 30 April.
What are the default UK payment terms?
Thirty days from receipt of the invoice or the goods, whichever is later, when nothing else was agreed in writing.
Can I charge interest once the due date passes?
Yes. Statutory interest is 8 percent above the Bank of England base rate, plus fixed compensation of 40, 70 or 100 pounds by debt size.
Is the calculator free?
Yes, it is free and needs no sign up.
