Hong Life CalculatorsUnderstanding the same-day delivery margin — concept and principle
Offering same-day or express delivery can win orders, but it usually costs much more to fulfil than standard shipping. If you absorb that extra cost, your margin on every express order shrinks. This calculator compares the gross margin of an order sent by standard delivery with the same order sent by express, including any express fee you charge the customer, so you can decide whether to charge for speed and how much. It works with any currency.
How it is calculated
- Margin with express = (price + express fee − product cost − express delivery cost) ÷ (price + express fee) × 100
- Margin with standard = (price − product cost − standard delivery cost) ÷ price × 100
Price is what the customer pays for the product, product cost is what it costs you, and the two delivery costs are what you pay the carrier. The express fee is any extra amount the customer pays for faster delivery; it is added to revenue on the express side.
The principle
Margin is profit as a share of revenue. Delivery is a variable cost tied to each order, so it comes straight out of profit. Because the price is unchanged while cost rises, even a few dollars of extra shipping removes a large slice of margin. An express fee works on both sides of the ratio: it adds to profit and to revenue, which is why a fee equal to the cost difference restores your profit in money but not quite your margin percentage.
Worked example
- Standard: profit = 35 − 15 − 4 = $16; margin = 16 ÷ 35 = 45.71%.
- Express with no fee: profit = 35 + 0 − 15 − 9 = $11; margin = 11 ÷ 35 = 31.43%.
- Express costs $5 more per order, which cuts profit per order by about 31% and margin by 14.3 percentage points.
- A $5 express fee would bring profit back to $16, with a margin of 16 ÷ 40 = 40%.
How to read the result
Compare the two margins with the minimum margin your business needs to cover overheads, returns and marketing. If express is only a small share of orders, a lower margin on those orders may be acceptable for the extra sales. If express becomes popular, a large margin gap can noticeably reduce overall profitability.
Common mistakes
- Comparing margin percentages without checking profit per order in money.
- Forgetting packaging, handling or failed-delivery costs that are higher for express.
- Including sales tax in the price.
- Assuming customers will buy just as often once you add a fee.
FAQ
Frequently asked questions
What express fee keeps the same margin percentage?
Solve for the fee that makes both margins equal. With these defaults it is about $9.21, more than the $5 cost difference, because the fee also increases revenue.
Is margin the same as markup?
No. Margin divides profit by price; markup divides profit by cost. Here, $16 of profit on $19 of product and delivery cost is a 45.71% margin but a markup of about 84%.
Should express be free above an order value?
Possibly, if larger baskets earn enough profit to absorb the extra delivery cost. Test the margin at that basket size.
