How the Charge Late Fees/Interest report calculates interest

To use the Charge Late Fees/Interest report correctly, it is important to know how it calculates interest.

The Charge Late Fees/Interest report uses this method to calculate interest for an overdue account:
  • Overdue account balance × interest rate ∕ 100 × number of days for the charge ∕ days in the year
Given these inputs for one client:
  • Overdue account balance: 225
  • Interest rate: 20 %
  • Number of days for the charge: 1 May to 31 May
The calculated interest rate is 3.82. (225 × 20 ∕ 100 × 31 ∕ 365 = 3.82)
