Ecommerce revenue can look healthy while contribution is thin. Product cost, freight, duties, pick-pack fees, return processing, payment fees, platform fees, discounts, and ad spend all compete for the same gross profit.
Use this calculator to test store-level or SKU-level margin before scaling paid acquisition, running promotions, or placing a larger inventory order. The output is strongest when paired with return rate and markdown assumptions.
Gross margin starts with revenue minus product and fulfillment-related direct costs. Net margin then subtracts operating expenses such as ads, software, labor, storage, creative, and admin overhead.
An online store records $150,000 in sales, $78,000 in product, freight, duties, and fulfillment cost, plus $44,000 in ads, software, labor, storage, and admin overhead.
The result should be reviewed with return rate and ad spend. If net margin is weak, a higher price may not be enough; the store may need lower landed cost, better shipping policy, or tighter acquisition spend.
Usually ad spend is tracked as an operating expense, but it should still be reviewed before scaling because it can erase contribution.
Estimate return processing, lost shipping, damaged inventory, and refund impact as part of your margin review.
Yes. Enter the revenue and direct costs for that SKU, then allocate the relevant operating expenses to interpret net margin.

Check payback before increasing inventory or ad spend.
Use when a digital product or subscription model is part of the plan.
Focuses on food cost, labor scheduling, delivery platform fees, waste, rent, and the difference between menu-level and month-level margin.
