Same order. Completely different picture.
An ordinary calculator stops at the difference between selling and purchase price. Here we go further — to the amount you can actually spend on running and growing the business.

How much does one order actually leave you?
The purchase price is only the first layer. Before an order turns into money, shipping, the payment fee, marketplace fees and returns take their share. Only what remains can pay for advertising — and only after that can you talk about what you earned.
What does a worked example look like?
A customer pays 1,490 including 21% tax, the goods cost you 620, shipping 149, the gateway takes 2.9% and returns average 55. Before advertising you're left with 497.66. If winning the order costs 300, you keep 197.66 — that's 16.1%.
How does tax enter the calculation?
Before anything is added up, every amount is converted to one economic basis. If you're registered for tax, output tax comes off revenue and input tax comes off costs, because you can reclaim it. The payment fee isn't converted — financial services are exempt, so there's nothing to reclaim. The country preset is only a suggestion; what you set is what counts.
- Revenue
- paid − discounts − refunds + shipping income
- Gross profit
- revenue − cost of goods
- Direct costs
- shipping + payment fee + marketplace fees + cost of returns + other variable costs
- Before ads
- gross profit − direct costs
- After ads
- before ads − ad cost
Counting a return twice
The refunded amount reduces revenue. Return shipping and the work involved are an extra cost. Put both in one field and the result looks worse than it is.
Advertising folded into the margin
You can't derive a break-even point from a margin that already has advertising deducted — it's circular and the number means nothing. That's why we start from the contribution before advertising.
Mixing prices with and without tax
Revenue including tax minus a purchase price excluding tax gives you a margin that doesn't exist anywhere. So the calculator converts everything to one basis first.
You might recognise one of these.
You have the data in WooCommerce, nobody turns it into a decision.
Margly builds profitability from it and says what to fix first.
You have plenty of stats plugins and still no view of profit.
This isn't another chart — it's how much an order leaves you.
Your margin is slipping and you can't tell whether it's prices or costs.
See the cost layers side by side and spot the one that moved.
