Understanding Ad Metrics
- ROI: (Revenue - Cost) / Cost × 100
- ROAS: Revenue / Ad Spend (return per $1 spent)
- CPA: Cost Per Acquisition = Spend / Conversions
- Good ROAS: 4:1 or higher for most industries
Tip: Track conversions properly with pixel tracking or UTM parameters to get accurate ROI calculations.

Input your total ad spend, the revenue generated from the campaign, and the number of conversions. You can also specify your profit margin for more accurate profitability analysis.
We Calculate Key Performance Metrics
The calculator computes your ROI percentage, ROAS ratio, cost per acquisition, and total profit. These metrics give you a complete picture of campaign performance.

Based on your ROI score, you receive tailored recommendations. Low ROI campaigns get optimization suggestions, while high performers get scaling strategies to maximize returns.
Why Marketers Use This Calculator
Complete ROI Picture
Go beyond simple profit calculations. This tool shows ROI percentage, ROAS, CPA, and profit together so you can evaluate campaigns from multiple angles.
Industry-Aligned Benchmarks
Results include context about what constitutes good performance. A 100 percent ROI gets flagged as excellent, while negative ROI triggers optimization alerts.
Actionable Recommendations
Instead of just showing numbers, the calculator provides specific next steps. Pause losing campaigns, optimize borderline performers, and scale winners.
CPA Tracking
Cost per acquisition is critical for paid advertising. See exactly how much each conversion costs and compare it against customer lifetime value.
Profit Margin Awareness
Factor in your actual profit margins to understand true profitability. Revenue alone does not tell the full story if margins are thin.
Frequently Asked Questions
What is a good ROI for advertising campaigns?
A good advertising ROI is typically 100 percent or higher, meaning you earn at least $2 for every $1 spent. Top-performing campaigns can achieve 200 to 500 percent ROI. Anything below zero means you are losing money on the campaign.
What is the difference between ROI and ROAS?
ROI measures profit relative to cost as a percentage. ROAS measures revenue per dollar spent as a ratio. For example, spending $1000 to generate $4000 revenue gives you 300 percent ROI and 4x ROAS. ROAS is more common in digital advertising, while ROI is used for overall business profitability.
How do I calculate cost per acquisition?
Divide your total ad spend by the number of conversions. If you spent $500 and got 25 conversions, your CPA is $20. This metric helps you determine if your advertising costs align with customer value.
Why is my ROI negative even though I made sales?
Negative ROI means your ad spend exceeded the revenue generated. This can happen with new campaigns still gathering data, poorly targeted ads, or products with low profit margins. Review your targeting, ad creative, and landing page to improve performance.
What ROAS should I aim for in Google Ads?
Most industries consider 4x ROAS (400 percent) a solid benchmark for Google Ads. E-commerce often targets higher, around 6x to 8x. Service businesses with high customer lifetime value can succeed with lower ROAS. Your break-even ROAS depends on your profit margins.
