What is a good ROAS?+
A "good" ROAS depends on your gross margin. As a rule of thumb, ecommerce brands need a ROAS of 2.5x-4x to be profitable after COGS, shipping, payment fees, and overhead. Subscription and high-margin digital products can be profitable at 1.5x-2x.
How do I calculate ROAS?+
ROAS = Revenue from ads ÷ Ad spend. Example: £20,000 in ad-driven revenue from £5,000 in ad spend = 4x ROAS.
What is break-even ROAS?+
Break-even ROAS is the ROAS at which your ad spend exactly equals your gross profit on the revenue it generates. Below this, you lose money on every order. Calculate as: 1 ÷ Gross Margin %.
Why is ROAS not enough?+
ROAS measures revenue per pound spent — but ignores margin, returns, customer lifetime value, and contribution margin. Pair ROAS with MER (Marketing Efficiency Ratio) and contribution margin per order for a true picture.
