Penalty interest is determined by the Interest Act. Penalty interest is the reference rate set by the European Central Bank in six-month intervals + 7 percentage points. The Bank of Finland announces the confirmed reference rate, the penalty interest rate and its period of validity at the end of June and December every year.
Penalty interest may be accrued from the due date onwards, assuming that a due date was set in the first place. If no due date was set, penalty interest generally begins to accrue 30 days after the date on which the creditor demands payment from the debtor.
For debts of private individuals where the debt is not related to the debtor's business activities, the rate of penalty interest may sometimes be negotiated.
Negotiation is possible if delayed payment is due to financial difficulties arising from illness, unemployment or other special circumstances and the cause is primarily not the debtor's fault.
Negotiation is also a possibility when sufficiently weighty justification for it exists. In assessing this, the following circumstances are considered:
Delayed payment and collection
