eCommerce Profit Calculator
The eCommerce profit calculator shows what you actually earn on a product sold online. Enter the purchase cost, selling price and units sold, then add packaging, delivery, your payment provider's fees, discounts, marketing, returns and VAT. It gives gross and net profit, margins, markup, the break-even price and units, and compares up to three scenarios. It runs entirely in your browser.

eCommerce Profit Calculator
Enter the purchase cost, selling price and units sold to see your profit.
Your estimate
Profit by scenario
- Gross profit is revenue minus the cost of the goods; net profit also takes off packaging, delivery, payment fees, marketing, returns and fixed costs.
- The break-even selling price is the price before any discount at which net profit is zero for the units you entered. Break-even units is how many units you must sell at your price to cover the fixed costs (and a marketing budget entered as a total).
- Returned orders: the product price is refunded, the delivery fee is kept, and the original order's packaging, delivery, payment fee and marketing are still paid. Payment fees are assumed not to be refunded.
- These are estimates from the figures you entered, not accounting or tax advice.
Everything is calculated in your browser. Nothing you enter is sent to our server or stored.

Limitations
- The results are estimates from the figures you enter. They are not accounting or tax advice.
- It models one product (or an average product) at a time. For a whole store, use average figures or run one scenario per product line.
- VAT is applied to the product price only, and VAT you may reclaim on purchases is not modelled: enter costs without reclaimable VAT.
- No payment provider's fees are filled in. Rates change and differ by plan, so enter the rate from your own provider.
What the calculator works out
All amounts are for one period, such as a month, and exclude any VAT you collect.
- Revenue is the product price customers keep paying after discounts and refunds, plus any delivery fees you charge.
- Cost of goods is what you paid for the units customers keep. If returned items cannot be sold again, it includes those too.
- Gross profit is revenue minus the cost of goods. Gross margin is gross profit divided by revenue.
- Net profit is gross profit minus packaging, the delivery you pay, payment fees, marketing, returns handling and fixed costs. Net margin is net profit divided by revenue.
- Markup is the price after discount (without VAT) minus the purchase cost, divided by the purchase cost.
- Break-even units is the fixed costs (plus marketing, if you entered it as a total) divided by the profit each unit contributes, rounded up.
- Break-even price is the selling price, before discount, at which net profit is exactly zero for the units you entered.
Payment fees are worked out on everything the customer pays through the provider, including delivery fees and any VAT added on top.
A worked example
You buy a product for 50 and sell it for 100. You expect to sell 100 units in a month with a 10% discount. You pay 2 per order for packaging and 15 for delivery (free to the customer). Your provider charges 2% per payment. You spend 5 per order on adverts, 5% of orders come back (each return costs 10 to handle, and the item goes back into stock), and your fixed costs are 500.
| Step | Calculation | Result |
|---|---|---|
| Price after discount | 100 − 10% | 90 |
| Revenue | 95 kept units × 90 | 8,550 |
| Cost of goods | 95 units × 50 | 4,750 |
| Gross profit (margin) | 8,550 − 4,750 | 3,800 (44.4%) |
| Variable costs | packaging 200 + delivery 1,500 + fees 180 + marketing 500 + returns 50 | 2,430 |
| Net profit (margin) | 3,800 − 2,430 − 500 | 870 (10.2%) |
| Markup | (90 − 50) ÷ 50 | 80% |
| Break-even units | 500 ÷ 13.70 per unit | 37 |
| Break-even price | the price at which net profit is 0 | about 89.61 |
A 44% gross margin shrinks to about 10% once delivery, fees and returns are counted. That gap is why the net figure matters when you set prices.
Use scenarios to test decisions
Add a scenario to copy your figures, then change one thing, such as charging for delivery, cutting the discount or raising the price, and compare the net profit and break-even price side by side. If you are still choosing where to sell, the eCommerce platform comparison lists each platform’s cost model so you can enter its subscription as a fixed cost. The online store readiness checker helps you prepare for launch.
VAT and payment fees in Ghana
If you are registered for VAT, tick the VAT option and enter the combined rate you charge. Then choose whether your prices already include it. The Ghana Revenue Authority’s VAT page lists VAT at 15% plus the NHIL (2.5%) and GETFund levy (2.5%), all charged on the same value, from 1 January 2026. Payment providers publish their own rates, for example in Paystack’s help centre. Use the rate from your own agreement, because it can depend on the payment channel and your plan.
When your numbers work, we can help you build the store and market it.
Frequently asked questions
How do I calculate the profit margin on a product?
Take the revenue from the product (after discounts and refunds, without VAT), subtract its costs, and divide by the revenue. Gross margin subtracts only the cost of the goods; net margin also subtracts packaging, delivery, payment fees, marketing, returns and fixed costs.
What is the difference between markup and margin?
Markup compares profit with the cost; margin compares profit with the selling price. A product bought for 50 and sold for 100 has a 100% markup but a 50% gross margin.
What is a break-even price?
It is the lowest selling price at which your sales cover every cost you entered, including fixed costs, for the number of units you expect to sell. Below it you make a loss.
Is the VAT I charge part of my revenue?
No. If you are registered for VAT, the VAT and levies you collect are paid over to the Ghana Revenue Authority, so the calculator leaves them out of revenue and profit. GRA's VAT page lists VAT at 15% plus the NHIL and GETFund levy at 2.5% each, from 1 January 2026.
Where do I find my payment provider's fees?
On the provider's pricing page, in your merchant agreement or in your dashboard. Fees are usually a percentage of each payment and sometimes a fixed amount per transaction; enter both in the calculator.
Does free delivery hurt my profit?
It moves the delivery cost from the customer to you. Add a second scenario with the customer paying a delivery fee and compare the net profit and break-even price of both.
