How Overdue Invoice Statutory Interest is Calculated
Under standard commercial terms and statutory payment regulations, interest on overdue invoices compounds daily based on an agreed annual percentage rate:
Daily Interest = Principal × (Annual Rate ÷ 100 ÷ 365)
Accrued Interest = Daily Interest × Days Past Due Date
Total Due = Principal + Accrued Interest + Flat Late Penalty Fee
Accrued Interest = Daily Interest × Days Past Due Date
Total Due = Principal + Accrued Interest + Flat Late Penalty Fee
Can freelancers legally charge late fees?
Yes. If late payment terms are explicitly stated in your client agreement or freelance contract, charging interest and administrative late fees is legally enforceable. In many jurisdictions, statutory interest applies even without explicit contract terms.
