Invoice Late Payment Interest Calculator
Statutory/contractual interest on an overdue invoice — including India's MSME 3× bank-rate compound penalty.
Formula
India's MSMED Act is a powerful lever: registered micro/small suppliers are owed compound monthly interest at 3× the RBI bank rate on payments beyond 45 days — and the buyer can't even deduct that interest for tax. Register on Udyam and cite §15-16; it transforms collection leverage.
