How Do I Know My Store Is Actually Profitable — What Do I Measure It With?
A store without an ecommerce profitability calculation can sink while revenue grows — the industry’s most common quiet story. Order counts rise, the bank balance keeps falling. 📊
Short answer: watch unit profit rather than revenue. Price − product cost − commission − shipping − advertising − returns. Without that figure you can’t know which product earns.
Below: the unit-profit calculation, the hidden cost lines, the three numbers to track and a ten-minute monthly routine. 🔬
How is unit profit calculated?
Ecommerce profitability starts with one product; totals come later.
How does a discount erase profit?
On a thin-margin product, a ten per cent discount can take half the unit profit. That’s why a discount must be designed: which product, at which threshold, for what purpose. A reflex discount raises sales and zeroes profit. 🏷️
Which three numbers should I track?
Dashboards offer dozens of metrics; an owner needs three.
Average order value, conversion rate, repeat rate
Average order value: the size of one order. Conversion rate: the share of visits becoming orders. Repeat rate: the share of customers buying again. Together they form the store’s health panel; improving one lifts the others. 📈
How is customer acquisition cost calculated?
If you advertise, this figure is mandatory.
Which product actually earns?
A store-wide average hides the individual truth.
How do I build the monthly routine?
Measurement doesn’t become a habit without rhythm.
The ten-minute monthly profit check
1) Review unit profit on your five best sellers. 2) Compare average order value and conversion with last month. 3) Divide ad spend by new customers. 4) Check the return rate. 5) Promote what earns; review what doesn’t. Five steps, ten minutes — and the store moves from guesswork into management. All questions in the 18-questions hub. ✅
📝 Field Notes
In one store we calculated the unit profit of the best seller: after shipping and returns it was nearly zero — and that product held the window space and the ad budget. Moving both toward earning products lowered revenue slightly and raised profit markedly. Revenue is pride; profit pays wages. 💰
📖 Quick Glossary
Unit profit: what remains from a single sale after every cost. Returns share: return costs spread across sales. Average order value: the average size of one order. Acquisition cost: spend needed to win one new customer.
⚡ Quick Summary
Measure unit profit, not revenue. 🧮 Shipping, advertising and returns are the forgotten lines. Three numbers suffice: order value, conversion, repeat rate. Repeat business is the hidden profit engine, and best-selling isn’t best-earning.

In order: purchase cost, payment commission, marketplace commission (if any), shipping, packaging, an advertising share and a returns share. The last two are usually forgotten, yet both are real costs that must be spread across every sale. 🧮
Because they aren’t visible at the moment of sale. But a returned item’s round-trip shipping and lost resale value come out of your other sales. Return rates vary hugely by category; measure your own and build it in. 🔄
Because it excludes cost. A loss-making sale bought with advertising still grows revenue. “We broke a record this month” means nothing without unit profit. The loss points sit in the loss article. 💸
Divide the month’s ad spend by the new customers it produced. If the result sits below your unit profit, advertising is earning. If above, two routes: raise conversion or grow the basket. 🎯
Completely. Acquisition is paid once, so the second sale arrives almost free. That’s why repeat business is ecommerce’s hidden profit engine — and it’s built on your own site rather than a marketplace: the own-store article. 🔁
A simple table suffices: product, units sold, unit profit, total profit. The result is the same in most stores — the best-selling product isn’t the best-earning one. Budget, advertising and window space then move toward what earns. 📋
Only on products with a high chance of repeat purchase, and only as a deliberate plan. If the customer never returns, a loss-making sale is simply a loss. You need your repeat rate measured before trying this strategy.
It can, but hidden shipping lowers it more. The common solution is threshold-based free shipping, which lifts basket size while balancing cost. What matters is the customer seeing the total early.
Accounting records the past; a unit-profit table drives decisions. They’re different jobs — one is a formal record, the other a management tool. Even a simple sheet shows you which product actually earns.
