Variables:

- SI is the statutory interest ($) P is the principal amount ($) r is the annual statutory interest rate (decimal) t is the time the money is borrowed or invested for (years)

To calculate the statutory interest, multiply the principal amount by the annual statutory interest rate, then multiply the result by the time the money is borrowed or invested for.

## What is a Statutory Interest?

Statutory interest is a rate of interest that is legally payable on a debt. It is set by law and applied to overdue payments to compensate the creditor for the delay in payment. The rate can vary depending on the jurisdiction and the type of debt, but it is typically calculated as a percentage of the amount owed. It is often used in legal proceedings and business transactions to encourage timely payment and discourage the accrual of debt.
