This tool calculates interest mechanically from stored rate data. It is not legal advice. Always check the contract, governing law, debtor status, and any sector-specific rules.
Frequently asked questions
Does the Norwegian rate change over time?
Yes. The calculator uses dated statutory rate periods and splits calculations when the rate changes.
Can I calculate interest up to today?
Yes. Use the calculator option to calculate up to today if the invoice remains unpaid.
Does the tool include recovery compensation?
It can include the latest stored recovery compensation where applicable, but the claim facts should be checked.
