How to Calculate PPC ROI
A PPC ROI calculation asks whether the gross profit attributed to paid clicks exceeds the cost of acquiring that traffic. It complements ROAS by accounting for the margin required to deliver the product or service.
Use one reporting scope
Match spend, clicks, conversions and revenue to the same account, campaign set, dates and attribution window. A conversion total from one window paired with spend from another creates a distorted return.
Value conversions realistically
For ecommerce, use attributable revenue per order. For lead generation, multiply close rate by average realized deal revenue to estimate value per lead. Avoid assigning every form submission the value of a completed sale.
Interpret ROI and ROAS together
ROAS shows revenue efficiency, while ROI shows the return after gross margin and ad spend. A campaign can have a positive-looking ROAS and still lose money when gross margin is low.
Use break-even CPC as a guardrail
Break-even CPC indicates the most you can pay per click at the entered conversion rate, value and margin before media profit reaches zero. It is a planning threshold, not an automatic bid recommendation, because performance changes by query, audience and position.

PPC ROI FAQs
How do you calculate PPC ROI?
Multiply conversions by revenue per conversion, apply gross margin to estimate gross profit, subtract PPC spend, divide by PPC spend and multiply by 100.
What is the difference between ROI and ROAS?
ROAS divides attributed revenue by ad spend. ROI in this calculator uses gross profit after cost of goods, then subtracts ad spend. ROI is therefore stricter and closer to campaign profitability.
How is break-even CPC calculated?
Break-even CPC equals conversion rate multiplied by revenue per conversion and gross margin. At that CPC, expected gross profit per click equals media cost per click.
Should I use revenue or profit per conversion?
Enter revenue per conversion and the calculator will apply your gross margin. For lead-generation campaigns, use a probability-weighted expected revenue per conversion rather than the eventual deal value of every lead.
Does this include agency or management fees?
The spend field should include any campaign costs you want evaluated. If you need fully loaded ROI, add agency fees, creative costs and relevant platform or personnel costs to ad spend.
