This calculator shows your true profit per order after all costs and fees are deducted. It is one of the most important metrics for ecommerce, advertising, and business growth.
If your unit economics are positive, your business can scale profitably. If they are negative, increasing sales will increase losses.
This tool helps you understand whether your pricing, costs, and marketing are working together to create a sustainable business.
The result shows your profit per order and margin after all direct costs and fees are deducted.
This is the key metric for advertising decisions. If your profit per order is lower than your cost to acquire a customer (CAC), your business is losing money.
Profit = Price − Cost − Fees
Margin = Profit ÷ Price × 100
This includes all direct transaction costs to give a realistic view of profitability.
Unit economics determine whether your business can scale. If you are running paid ads, your profit per unit must exceed your customer acquisition cost.
For example, if you make £12 per sale but your ads cost £15 per customer, you lose £3 per order. Scaling this will increase losses.
Strong unit economics allow you to scale confidently, reinvest in growth, and increase total profit.
Example 1:
Price £40, Cost £18, Fees £6 → Profit £16 → Margin 40%
Example 2:
Price £25, Cost £14, Fees £3.50 → Profit £7.50 → Margin 30%
Example 3 (Ads):
Profit £10, Ad cost £12 → Loss £2 per sale
Profit per sale after all costs.
They determine scalability.
No, this increases losses.
