Suppliers often offer terms like “2/10, net 30”, meaning you get a 2% discount if you pay within 10 days, otherwise the full amount is due in 30 days. While skipping the discount might seem insignificant, it actually incurs a very high effective annual cost.
The Annualized Cost of Trade Credit Calculator helps businesses understand how expensive it is to pass on such early payment discounts — and why they should take them when possible.
Formula
Annualized Cost of Trade Credit = (Discount % / (100 – Discount %)) × (365 / (Net Days – Discount Days))
This formula annualizes the effective interest rate of forgoing the discount over the remaining credit period.
How to Use the Annualized Cost of Trade Credit Calculator
- Enter the Cash Discount (%) – e.g., 2% if terms are “2/10”.
- Enter Discount Period (days) – e.g., 10 for “2/10”.
- Enter Net Period (days) – e.g., 30 for “net 30”.
- Click “Calculate” – The tool shows the annualized cost as a percentage.
Example
Let’s consider the payment terms “2/10, net 30”:
- Discount = 2%
- Discount Days = 10
- Net Days = 30
Using the formula:
Annualized Cost = (2 / (100 – 2)) × (365 / (30 – 10)) = 0.02041 × 18.25 = 37.27%
So, skipping the 2% discount is like paying 37.27% interest annually, which is very expensive compared to most financing options.
