Calculate The Effective Cost of The Following Trade Credit Terms

Understanding the effective cost of trade credit terms is crucial for businesses to make informed financial decisions. This calculator helps you determine the true cost of credit terms by converting them into an annual percentage rate (APR).

What is the effective cost of trade credit terms?

The effective cost of trade credit terms represents the true cost of borrowing money through credit terms. It accounts for the time value of money and provides a more accurate comparison of different credit options.

Common trade credit terms include:

Net 30: Payment due in 30 days
2/10 Net 30: 2% discount if paid within 10 days, otherwise due in 30 days
EOM: Payment due at the end of the month

The effective cost helps businesses understand how much they're really paying for credit and compare different suppliers' terms.

How to calculate the effective cost

The effective cost is calculated by determining the annual percentage rate (APR) equivalent to the given credit terms. The formula used is:

Formula

Effective Cost = (1 + (Discount Rate × Discount Days) / 360) × (1 + (1 - Discount Rate) × (Due Days / 360)) - 1

Where:

Discount Rate is the percentage discount offered for early payment
Discount Days is the number of days within which payment must be made to receive the discount
Due Days is the total number of days until payment is due

For example, with 2/10 Net 30 terms:

Discount Rate = 2% (0.02)
Discount Days = 10
Due Days = 30

Note

This calculation assumes a 360-day year for simplicity. Some industries use 365-day years, which would slightly affect the result.

Example calculation

Let's calculate the effective cost for 2/10 Net 30 terms:

Calculation Steps

1. Calculate the first factor: (1 + (0.02 × 10) / 360) = 1.005556

2. Calculate the second factor: (1 + (1 - 0.02) × (30 / 360)) = 1.077778

3. Multiply the factors: 1.005556 × 1.077778 = 1.08476

4. Subtract 1: 1.08476 - 1 = 0.08476 or 8.476%

The effective cost for 2/10 Net 30 terms is approximately 8.48%. This means the credit terms are effectively costing you about 8.48% per year.

How to use this calculator

Frequently Asked Questions

What is the difference between effective cost and APR?: The effective cost is similar to APR but specifically tailored for trade credit terms. Both represent the true cost of borrowing, but APR is more commonly used for consumer loans.
How does the effective cost affect my cash flow?: The effective cost shows how much you're effectively paying for credit. Higher effective costs mean you're paying more in interest, which can impact your cash flow and profitability.
Can I use this calculator for international credit terms?: This calculator uses a 360-day year calculation, which is common in the US. For other regions, you may need to adjust the calculation method.
What if my supplier offers different credit terms?: You can use this calculator to compare different credit terms from different suppliers to choose the most cost-effective option.
Is the effective cost the same as the interest rate?: No, the effective cost accounts for the timing of payments and discounts, providing a more accurate representation of the true cost of credit.
