Revenue is not profit. An online order loses margin to product cost, packaging, shipping, platform fees, payment fees, discounts, ad spend, returns, chargebacks, and fixed overhead — this calculator estimates what you actually keep.

Ecommerce profit per order = net revenue − goods − fees − shipping − returns − marketing − fixed overhead per order. A $40 product with $4.95 shipping charged, $15.50 of landed goods and fulfilment costs, $1.60 of payment fees (2.9% + $0.30), $5.50 outbound shipping, a $0.84 return allowance (4%), and $6 of ads contributes $15.51 per order (34.5%); after $5 of overhead per order the net profit is $10.51 — and the campaign needs at least a 2.09 ROAS to break even.

A 12-sheet Excel workbook generated from your exact inputs
Contribution = 44.95 − 29.44 = $15.51 per order (34.5%). With $3,000 of monthly overhead spread over 600 orders ($5/order), net profit = $10.51 (23.4%), or roughly $6,304 a month, and the overhead breaks even at 194 orders a month.
Every mode runs those four formulas in that order, and the three margins they produce tell you where the money went. Gross profit removes only landed goods and packaging, so this order shows $30.95 (68.9%) and the SKU looks superb. Contribution also removes fees, shipping, returns and marketing: $15.51. Net removes overhead too: $10.51. An order can look healthy on gross profit and still lose money net, because the middle cost lines are where ecommerce margins go to die.
34.5% contribution and 23.4% net answer different questions
Contribution margin is contribution profit as a share of net revenue, and it is the most useful per-order number here: positive contribution means every extra order helps cover overhead, while negative contribution means volume makes things worse and no amount of growth rescues the SKU.
Net margin is volume-dependent, so it answers a different question. The $5 of overhead per order above exists only at 600 orders a month; at 194 orders it consumes the whole $15.51 contribution, and below that the same product loses money while its 34.5% contribution margin has not moved. Contribution decides whether to sell the product; net profit decides whether this month’s volume pays for the business around it.
There is no single "good" ecommerce margin to judge either figure against — category, channel, country, fulfilment model, ad intensity, return rates and product type all shift the bar, so treat any benchmark as a shape to sanity-check, never a target.
A 3× ROAS still loses money when your floor is 3.5×
Break-even ROAS is the gross charge per order — what the customer pays, the figure ad platforms report as revenue — divided by the largest ad spend the margin can absorb, which is contribution with the ad cost added back. Here that is $44.95 ÷ $21.51 = 2.09, so $21.51 is also the most you can pay to acquire the order.
Watch this card hardest if you buy traffic, because the ad dashboard cannot see your costs: a 3× ROAS the platform calls a win still loses money when your floor is 3.5×, since ROAS measures revenue per ad dollar, not margin per ad dollar. Use Scenario Planner before raising a budget — a discount, free shipping, heavier ad spend or a supplier price rise each move the floor.
What a 4% return rate costs: $0.84 an order
A return refunds the revenue while you still pay reverse shipping and processing, so it is a cost line, not a missing sale. The detailed model charges return rate × (refund + reverse shipping + reverse logistics − net recovery), where net recovery is the resale value of returned stock; the goods cost is expensed further up the pipeline, so it is never counted twice. At 4% that allowance is $0.84 — ignorable until the rate doubles and returns cost more than the payment fees.
Simple rate or detailed model, the output is an expected value, not a forecast. Real losses arrive lumpily and depend on resale recovery and condition grading, so a quarter with three unsellable high-value returns will not match the smooth per-order figure.
Every preset fee here is a starting point, not a rate
Amazon, Shopify, Etsy, eBay, Walmart, Flipkart and WooCommerce each ship with a fee preset, and every one is an illustrative example rather than a live rate: fees vary by country, category, plan and date, and this page fetches nothing. Read the current referral, closing, fulfilment and payment lines off your own seller dashboard and overwrite the preset before you trust a margin. Channel Comparison then runs one product through up to three fee structures at once — the honest way to decide whether a SKU belongs on a marketplace or your own store.
There is no dedicated Meesho preset: start from Flipkart or the generic "Other marketplace" option and edit the referral, shipping and payment fees to Meesho’s own schedule, since reseller-platform fees differ from marketplace fees. Indian sellers are otherwise covered — INR sits among the 12 currencies, and Flipkart has a preset of its own.
Nothing here is category-specific either: enter cost of goods, price and fees for whatever you sell — gold, jewellery, supplements, furniture — and the arithmetic is identical, so there is no gold preset to hunt for. And this is a web calculator you use on this page, not a browser extension that overlays profit figures on marketplace listings; the numbers come from what you type.
Where the per-order model stops and your accountant starts
This models ONE representative order. It is not bookkeeping, a P&L, or a tax computation, and it does not know what you actually sold last month.
Two limitations follow. Monthly and yearly projections assume volume and per-order economics stay constant, which they do not: fee tiers, carrier rates and ad efficiency all change with scale. And income taxes, working-capital timing, inventory carrying costs and customer-lifetime effects such as repeat orders cannot be priced here at all — for acquisition economics across a whole customer lifetime, use the LTV:CAC calculator.
This page answers “what do I keep per order?” — these tools take the neighbouring questions:

This page models one representative order from the numbers you enter. It fetches nothing: not platform fees, not carrier rates, not tax rates, not your seller dashboard. The sources below cover the parts of the order that are actually governed by a published rule or a published rate: refund obligations, regulated debit interchange, postal rates, and the contribution-margin arithmetic behind break-even orders.
The marketplace fee presets are the honest exception. Amazon, Flipkart, Etsy, eBay, Shopify, Walmart and WooCommerce fees are set by those companies in commercial fee schedules that change without notice, and no regulator publishes or approves them. The presets here are illustrative starting points, not rates we can cite an authority for. Read your own current fee schedule and overwrite them before you trust a margin.
This ecommerce profit calculator and its XLSX workbook are for educational and business-planning purposes only. They model one representative order from the figures you enter; platform fees, payment processing costs, tax treatment, shipping rates, advertising results, return behaviour, and business outcomes vary by country, platform, category, plan, date, and seller circumstances. Platform fee presets are examples only — always verify current rates on the platform’s own fee pages. This is not accounting, tax, legal, investment, or financial advice. Verify important decisions with current fee pages and a qualified professional.
