Q: What is the difference between ROAS and ROI?A: ROAS (Return on Ad Spend) specifically measures revenue from advertising investment. ROI (Return on Investment) measures overall investment profit including all costs. Simply put, ROAS tells you how much revenue your ad spend generated, while ROI tells you if you're making an overall profit.
ROAS Calculator
Optimize your advertising strategy by calculating the profit contribution of your campaigns
ROAS = Revenue / Ad Spend. Different categories have different ROAS standards, please adjust the target according to actual circumstances.
Break-even ROAS is the critical point where advertising campaigns neither lose nor make money. When actual ROAS is higher than this value, campaigns start to be profitable.
When ROAS is above 0.0x, advertising campaigns start to be profitable
The calculation results are for reference only. Actual results may vary due to market fluctuations, seasonality, and other factors.
Use this ROAS calculator when you need a quick, explainable answer to whether an ad campaign is below breakeven, inside the acceptable range, or ready for more budget. Treat the number as a decision input, not the whole decision: compare it with gross margin, refund risk, repeat purchase quality, and the attribution window before scaling.
Inputs
What to enter
Enter ad spend, attributed revenue, target ROAS, and any margin or breakeven assumptions you want the team to review. Use the same date range for spend and revenue.
Outputs
What you get back
The calculator returns current ROAS, gap to target, breakeven context, and a simple reading that can be copied into a weekly ad review.
Formula
Core rule
ROAS = revenue attributed to ads divided by ad spend. A 3.0 ROAS means every 1 dollar of ad spend generated 3 dollars of revenue before product cost, fees, refunds, and overhead.
Example
Example result
If a campaign spends $500 and reports $1,850 in attributed revenue, ROAS is 3.7. If your breakeven threshold is 2.4, the campaign has room for cautious scaling; if refund rate is rising, hold budget and inspect order quality first.
Use it when
Best use cases
Use it for weekly Meta, Google, TikTok, or affiliate campaign reviews, first scaling decisions, and quick checks before increasing budget.
Do not use it when
Limits
Do not use platform ROAS alone to approve spend when attribution windows differ, revenue is inflated by existing customers, or the store has not checked contribution profit.

What is the difference between ROAS and ROI?
ROAS (Return on Ad Spend) specifically measures revenue from advertising investment. ROI (Return on Investment) measures overall investment profit including all costs. Simply put, ROAS tells you how much revenue your ad spend generated, while ROI tells you if you're making an overall profit.
What is a good ROAS value?
Generally, ROAS of 2:1 (spending $1 to generate $2 revenue) is the break-even point. Excellent ecommerce ad ROAS is typically between 3:1 and 5:1. However, this varies significantly by category, so compare with category averages for accurate assessment.
How to calculate break-even ROAS?
Break-even ROAS = Product Cost / Sale Price. For example, if product cost is 50% of the selling price, break-even ROAS is about 2:1. Below this means advertising loss, requiring strategy optimization or improving product margin.
How to set attribution window?
Attribution window is how many days after clicking an ad purchases are attributed to it. Common settings include 1-day, 7-day, 30-day click attribution. Longer windows capture more conversions but may overestimate early ad effectiveness.
Why does my ROAS fluctuate so much?
ROAS fluctuation is normal and can be influenced by many factors: promotions, competitor bidding, seasonal changes, audience reach differences, etc. We recommend viewing 7-day or 30-day rolling average ROAS for more stable evaluation.
How to improve ROAS?
Ways to improve ROAS include: optimizing ad creatives for better CTR, precise audience targeting, improving landing page experience, optimizing keywords and bidding strategies, and increasing product conversion rates. We recommend continuous A/B testing and data monitoring.
