FAQs

ROAS stands for Return on Ad Spend. It is the total revenue your ads generate divided by the amount you spent on them. A ROAS of 4x means every $1 of ad spend brought back $4 in revenue. It is one of the most direct ways to measure whether a paid campaign is working.
ROAS = Revenue from ads / Cost of ads. So if you spent $1,000 on a campaign and it generated $4,200 in revenue, your ROAS is 4.2x (or 420%). Our calculator runs this math in real time as you type.
A common rule of thumb is that 3x ROAS or higher is healthy for most e-commerce and lead-gen campaigns, 4x and above is strong, and anything above 5x is excellent. Anything below 1x means you are losing money on every dollar spent. The right target for you depends on your profit margin, which is why we built a break-even mode.
Break-even ROAS is the minimum ROAS your campaign needs to stop losing money once you factor in your profit margin. The formula is Break-even ROAS = 1 / profit margin. With a 30% gross margin, your break-even ROAS is about 3.33x. Anything below that is unprofitable even if revenue exceeds ad spend.
ROAS only compares revenue to ad spend. ROI compares profit (revenue minus all costs, including product cost, fees and overhead) to the cost of the investment. A campaign can have a great ROAS but a poor ROI if your margins are thin. Our calculator shows both numbers side by side.
The fastest levers are usually: better landing pages with higher conversion rates, sharper audience targeting, stronger ad creative and offers, pausing your worst-performing ad sets, and increasing average order value with bundles or upsells. A high-converting landing page is often the biggest multiplier.
Yes. ROAS is a universal metric, so the calculator works for any paid channel where you can pull ad spend and revenue. Plug in your numbers from Meta Ads Manager, Google Ads, TikTok Ads, native ad platforms, affiliate networks or email campaigns.
