How to use this calculator

Enter ad spend, revenue, impressions, and clicks. The calculator builds a compact campaign dashboard and scores the campaign across profitability, engagement, and cost efficiency.

What the result means

The result is a campaign grade that combines profitability and traffic efficiency instead of judging a single KPI.

ROAS = revenue / spend; CTR = clicks / impressions; CPC = spend / clicks; CPM = spend / impressions × 1000. Conversions use a 5% click conversion benchmark.

Use this calculator as a campaign health check before increasing budget or pausing ads.

Example calculation

With $5,000 spend, $22,000 revenue, 150,000 impressions, and 7,500 clicks, ROAS is 4.4x, CTR is 5%, and CPC is $0.67.

Tips for better results

  • Scale only when ROAS and CPA are both healthy.
  • Use CTR and CPC to diagnose ad relevance.
  • Use conversion rate to diagnose landing page performance.

FAQ

How do I measure Google Ads campaign performance?

Measure ROI, ROAS, CTR, CPC, CPM, CPA, conversion rate, cost per lead, and campaign grade together instead of judging one metric alone.

What KPIs matter most in Google Ads?

The most important KPIs are usually ROAS, ROI, CPA, conversion rate, CTR, CPC, and revenue, depending on whether the campaign goal is profit, leads, or awareness.

When should I increase my Google Ads budget?

Increase budget when ROAS and ROI are profitable, CPA is below target, conversion tracking is reliable, and the campaign still has impression share or volume opportunity.

How do I optimize Google Ads campaigns?

Prioritize the weakest metric: improve CTR for ad relevance, CPC for cost control, conversion rate for landing pages, and ROAS or ROI for profitability.

What is a good Google Ads campaign score?

A strong score usually means profitable ROI, acceptable CPA, healthy CTR, efficient CPC, and conversion rates that support your revenue target.
