For African small and medium-sized enterprises (SMEs), offering or accepting an early payment discount is a high-stakes financing decision rather than a simple sales gesture. In high-inflation markets like Nigeria, where commercial bank lending rates frequently exceed 35 percent, these terms directly impact survival.
Deciding whether an early payment discount is worth it requires comparing the implied annualised cost of the discount against the business’s actual cost of capital.
Calculating the real cost of cash
Many business owners view a 2 percent discount as a minor concession. Because these discounts are applied over short windows of 10 to 20 days, their annualised finance rates are often higher than bank loans.
To determine the annualised rate of a discount, SMEs use the standard cost-of-discount formula. This formula multiplies the discount ratio by the annual turnover rate of the cash.
For terms listed as 2/10 Net 30, meaning a 2 percent discount if paid within 10 days instead of 30, the math is straightforward. The buyer saves 2 percent by paying 20 days early.
The calculation is: (2 divided by 98) multiplied by (360 divided by 20). This results in an annualised rate of 36.7 percent.
When to accept a discount as a buyer
If you are the buyer, determining if an early payment discount is worth it depends on your current cash reserves and borrowing costs.
If your business has idle cash in a business current account earning little to no interest, accepting a 2/10 Net 30 discount is highly lucrative. You are effectively earning a 36.7 percent risk-free return on that capital.
The decision changes if you must borrow to pay early. If your business relies on a bank overdraft facility charging 30 percent interest, borrowing at 30 percent to secure a 36.7 percent return saves you money.
If your bank overdraft rate is 40 percent, borrowing to pay early is a net loss. You would be paying more in bank interest than you save on the invoice.
Buyers must also protect their operational runway. Securing a discount is counterproductive if it leaves the business without enough cash to meet immediate payroll or utility obligations.
When to offer a discount as a seller
For sellers, offering a discount is an alternative to borrowing working capital. If your customers routinely pay late, your cash flow stalls, forcing you to seek expensive commercial loans.
Suppose your alternative is invoice discounting or a bank loan costing 40 percent annually. Offering 2/10 Net 30 terms, equivalent to 36.7 percent, is actually a cheaper way to fund your operations.
Offering discounts can also reduce collection costs and lower the risk of bad debts. This is particularly valuable when dealing with buyers who have unreliable credit profiles.
The risk for sellers is margin erosion. If reliable customers who would have paid in full anyway begin using the discount, you are unnecessarily giving up 2 percent of your top-line revenue.
Aligning discounts with cash flow needs
SMEs should avoid offering blanket discounts to all clients. A more sustainable strategy is targeting specific accounts where payment cycles are slow or where immediate cash is required for inventory.
Sellers must also track their gross margins. If your gross margin is below 15 percent, a 2 percent discount represents a massive portion of your profits and may threaten business viability.
To apply this practically, review your outstanding invoices this week. Calculate the annualised rate of any discounts you currently offer or receive, and compare them directly to your bank’s lending rates.
