Which rate can I claim?

5% a year: the legal rate (art. 104 of the Code of Obligations), due even if you did not write it on the invoice. A higher rate is only possible if it was agreed by contract.

From when does interest run?

As soon as the customer is in default: the day after the due date if it was agreed with them; otherwise from your reminder (art. 102 of the Code of Obligations).

Can I also charge reminder fees?

Only if they were agreed with the customer, for example in terms and conditions they accepted. The law only provides for late payment interest: if in doubt, do not add fees.

Why divide by 365?

The calculator counts the actual days late and relates them to a 365-day year: easy for your customer to check. A 360-day calculation would give a barely higher amount.
