Compound interest refers to the interest earned on interest income that has already been credited. Capital and interest income grow at a disproportionately high rate, as the Interest charges interest again.

Detailed explanation/description:
In the traditional world of finance, the compound interest effect describes the reinvestment of interest income in the same capital investment, whereby the capital grows exponentially. In SAP Business One, compound interest in the narrower sense does not play an operational role, as the system primarily works with simple interest. This applies in particular to the calculation of interest on arrears as part of the Dunning.
According to Section 248 (1) of the German Civil Code (BGB), companies are not permitted to charge contractually agreed compound interest. Instead, SAP Business One generally calculates an annual interest rate for overdue receivables based on the remaining amount or the original amount. Compound interest as an automatic mechanism for recouping interest is not used in the system.
Integration into business processes
Interest is calculated within the dunning process via the Dunning terms. You can configure whether and how interest on outstanding receivables is calculated and automatically posted.
