Discount and sale-profit calculator for Kenya

It is the largest discount you can offer before your sale price no longer covers the costs entered. Fixed costs such as rent and salaries should be included separately when relevant.

Yes. Include any fee or delivery amount your business pays for each sale so the promotion result is realistic.

The sale price is the normal price multiplied by one minus the discount. For example, a KSh 2,500 item at 20% off sells for KSh 2,000. The calculator caps the discount at 100% and applies the payment fee to the discounted price, not the original price.

Profit is the discounted sale price minus your total cost per sale and the payment fee. Margin is that profit expressed as a percentage of the discounted price. A KSh 2,000 sale price with KSh 590 profit left gives a 29.5% margin.

The calculator calls this the break-even discount. It is based on your cost and payment fee and shows the percentage where profit reaches zero. With a KSh 2,500 price, KSh 1,400 cost, and 0.5% fee, the break-even discount is about 43.7%, so stay below it unless you are deliberately clearing stock.

Not always, but on an item whose cost is more than half of its price, a 50% discount can wipe out profit before the payment fee. The break-even discount tells you the exact limit for your item. Only go beyond it with a deliberate reason, such as clearing slow stock or gaining customers.

The calculator deducts the fee percentage from the discounted sale price before working out profit, and the fee field accepts up to 99%. A higher fee takes a larger slice of a smaller sale price, which lowers the break-even discount and makes the promotion riskier.

Margin is profit divided by the sale price, while mark-up is profit divided by your cost. On a KSh 2,000 sale with KSh 590 profit, the margin is 29.5% but the mark-up on a KSh 1,400 cost is about 42.1%. The calculator shows margin, not mark-up.
