01Why it starts from the price
Most break-even calculators ask for a contribution margin. The trouble is that this is exactly the number people do not know — and a five point guess moves break-even noticeably.
Here it is calculated instead: order value minus cost of goods, shipping, packaging and fees. The margin becomes a result rather than an assumption.
02Returns belong in the maths
A returned order brings no revenue but has cost shipping both ways plus handling. In categories with high return rates it moves break-even significantly, and it is the line most often left out.
If you do not know your return rate by category, it is one of the most valuable numbers to pull from the shop.
03Break-even ROAS and POAS
Break-even POAS is always 1. That is the whole point of POAS: the number is built so that zero is zero, regardless of industry and margin.
Break-even ROAS differs for every business — it is 1 divided by the contribution margin. That is why two shops can share a ROAS while only one of them makes money.
Questions
What is a good ROAS?
There is no number that holds across businesses. A good ROAS sits above your break-even with enough room to cover fixed costs. At a 40 % margin break-even is 2.5; at 20 % it is 5.
Should I include VAT?
No. VAT is not your money. Including it makes the margin look better than it is and sets break-even too low.
