How this calculator works
The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
Contribution before ads
In direct-cost mode, subtract the product cost attached to the attributed sales from attributed revenue. In margin mode, apply the gross-margin percentage entered by the owner. Negative pre-ad contribution remains negative.
Contribution after ads
Subtract ad spend from the contribution before ads. ROAS is shown separately as attributed revenue ÷ ad spend; ROAS is a revenue-efficiency metric and does not by itself establish profitability.
