You can use this tool to calculate the total amount owed (including interest) on court-awarded civil judgments where the Interest on Money Claims Act 2016 has been applied. It allows you to calculate the total amount owed if paid in either a single payment or by instalments on the 'end date' entered. Please refer to the FAQ for more information, including how calculations are made and when interest applies. Please note that the Act and calculator only apply to civil proceedings started after 1 January 2018.
