Should a Credit Line Fund an Early-Payment Vendor Discount?
An early-pay discount can be worth less than it looks once interest and fees are included.
In this guide
An early-pay discount can be worth less than it looks once interest and fees are included.
How to approach the decision
Compare the dollar discount with interest on the discounted invoice balance. The cash cost starts when the draw is funded and ends when you actually repay the line.
Worked example
| Input | Example |
|---|---|
| Undiscounted invoice ($) | $24,000.00 |
| Early-pay discount (%) | 2 |
| Annual borrowing rate (%) | 12 |
| Days financed | 35 |
| Additional draw fee ($) | $110.00 |
| Result | Estimate |
|---|---|
| Net savings from borrowing to pay early | $99.36 |
| Vendor discount | $480.00 |
| Borrowing interest and fees | $380.64 |
Uses simple interest on the discounted invoice balance, the entered number of days and a fixed borrowing fee. The model excludes supplier penalties and other changes in terms.
What to verify
Match the timing to expected receipts and check whether the supplier will honor the discount on the planned payment date.
