Gross vs net margin
The margin on your price tag is not the margin you keep
Most sellers know their gross margin: the gap between what they paid for an item and what they sell it for. Net margin is the number that pays the bills. It is what is left after every cost of getting that sale to the customer.
Gross profit margin
(Price − buying cost) ÷ price × 100
Shows how well you buy and price your stock.
Net profit margin
(Price − all costs) ÷ price × 100
Shows what you actually keep from each shilling of sales.
Worked example: a KSh 1,500 handbag
You buy the bag for KSh 900 and sell it for KSh 1,500. Gross profit is KSh 600, a 40% gross margin. Now add packaging (KSh 30), delivery you cover (KSh 100), ads spent per order (KSh 50) and the M-PESA Business Till charge (KSh 7.50). Net profit falls to KSh 412.50, a 27.5% net margin. Twelve and a half points of margin went to costs that never show on the price tag.
Where margin usually leaks
- Free delivery. A KSh 150 rider fee on a KSh 1,000 order is 15 points of margin gone.
- Discounts. A 10% discount can cut your net profit by a third or more, because your costs do not shrink with the price.
- Ads. Divide your monthly ad spend by the orders it brought in. That is a cost on every one of those sales.
- Payment fees. Small per payment, but they add up across a busy month.
- Returns and breakage. Add an allowance in "Other cost" if some orders come back or break in transit.

Profit margin questions
Profit margin is profit divided by the selling price, times 100. If you sell a bag for KSh 1,500 that cost you KSh 900, your gross profit is KSh 600 and your gross margin is 600 ÷ 1,500 = 40%. Take off packaging, delivery, ads and payment fees as well and you get your net margin, the share of the price you actually keep.
