What is the ROAS Calculator?
The ROAS Calculator measures Return On Ad Spend by dividing campaign revenue by ad spend. ROAS is the primary success metric for paid advertising campaigns across Google, Meta, LinkedIn, and other platforms. It tells you how many dollars you earn for every dollar spent on ads.
How does it work?
Enter the total revenue attributed to your advertising campaign. Enter the total spend on that campaign including ad platform costs, creative production, and management fees. The calculator divides revenue by spend to show your ROAS as a multiplier.
Formula
campaign revenue / ad spend
How the calculation works
How the calculation works
- 1Input campaign revenue ($120,000) and ad spend ($30,000).
- 2Divide revenue by ad spend: $120,000 / $30,000 = 4.0.
- 3Result: 4.0x ROAS, meaning $4.00 of revenue per $1.00 spent.
Worked example
Worked Example
BrightLeaf Coffee, a DTC coffee brand, runs a month-long Meta holiday campaign and attributes $120,000 in revenue to $30,000 in ad spend.
- 1Attributed revenue: $120,000.
- 2Total ad spend: $30,000.
- 3Divide revenue by spend: $120,000 / $30,000 = 4.0.
- 4ROAS is 4.0x.
Result
BrightLeaf's holiday campaign returned 4.0x ROAS, earning $4.00 in revenue for every $1.00 spent.
Interpretation guide
How to read your result
Revenue does not cover ad spend plus product and overhead costs, so you are likely losing money on ads.
Pause poor segments, rework creative and targeting, and fix landing page conversion rate before scaling.
You roughly cover costs with little margin left; typical for broad cold-audience campaigns.
Raise average order value and conversion rate, then shift budget toward your best ad sets.
A healthy, profitable zone for most ecommerce brands, matching typical paid channel performance.
Scale winning campaigns gradually and reinvest into top creatives and audiences.
Strong revenue efficiency that often indicates under-spending on a proven winner.
Increase budget, expand to lookalike audiences, and test new placements to capture more demand.
Benchmarks
Typical ROAS by channel for ecommerce. A 2:1 return is roughly break-even for most brands once product costs and overhead are included.
| Channel | Typical | Strong |
|---|---|---|
| Google Search | 3-5x | 6x+ |
| Meta (Facebook / Instagram) | 2-4x | 5x+ |
| TikTok | 1.5-3x | 4x+ |
| Display | 1-2x | 3x+ |
Common mistakes
- - Not including all costs creative production, landing page, and attribution tools
- - Using last-click attribution when assisted conversions matter
- - Comparing ROAS across channels without adjusting for different attribution windows
Practical tips
Practical tips
Use a consistent attribution window, such as 7-day click and 1-day view, so comparisons across channels are fair.
Include creative production, landing page, and management fees in ad spend, or you will overstate ROAS.
Slice ROAS by campaign, ad set, and audience; a blended 4x can hide segments running at 1x.
Match your ROAS target to your margin: a 50% contribution margin needs roughly 2:1 just to break even.
Judge ROAS on trends over 7-14 days, not a single day, since daily data is noisy.
Pair ROAS with conversion rate and volume; high ROAS on tiny volume leaves growth on the table.
When should you use it?
- - Weekly and monthly campaign performance reviews
- - Comparing performance across ad platforms and audiences
- - Deciding whether to scale, optimize, or pause campaigns
- - Reporting advertising efficiency to stakeholders
Benefits
- - Provides a clear profitability signal for every ad dollar spent
- - Enables comparison across channels, campaigns, and time periods
- - Helps identify which campaigns to scale and which to pause
Step-by-step example
Pull your attributed campaign revenue from your analytics platform, ensuring proper conversion tracking is in place. Total all costs including ad platform fees, creative production, and agency or tool costs. Divide revenue by total cost to get your ROAS. Most ecommerce businesses target a 4:1 ROAS.
Real-world example
A DTC brand spends $30,000 on Meta Ads in a month and generates $120,000 in attributed revenue. Their ROAS is 4.0x meaning every dollar spent returns four dollars. If their target ROAS is 3.5x, the campaign is profitable.
