What is a good ROAS and how do you use this ROAS calculator?
ROAS — return on ad spend — is the revenue you earn for every pound you put into a campaign. The ROAS formula is simple: revenue attributed to the campaign divided by the ad spend behind it. A 4.0× ROAS means £4 back for every £1 spent; expressed as a percentage that is 400%. This calculator takes your revenue and spend and instantly returns your ROAS, the same figure as a percentage, and the gross profit left over.
As a rough benchmark, many teams treat 4× as a healthy target and anything under 2× as a warning sign, because once you subtract product, fulfilment and platform costs a low multiple can still lose money. The fastest lever on ROAS is usually not more budget but better creative: screenshots and ads that convert a higher share of the same clicks lift revenue without raising spend — exactly what Reverze rebuilds for App Store campaigns.
