Here’s everything you need to know: what it is, why it matters, how to calculate it, and how to optimize it! Formula Campaign Performance Index · \= · Actual Campaign PerformanceExpected Performance · × 100 **Example.** If a campaign is expected to deliver 1,000 leads but generates 1,300, the Campaign Performance Index is 130 – meaning the campaign outperformed expectations by 30%. ## Overview ## What it is Campaign Performance Index is a composite metric used to evaluate the success of a campaign by comparing actual performance against a baseline or expected value. It combines various KPIs like clicks, conversions, and ROI into a single score to simplify comparison across campaigns. ## Why it matters Campaign Performance Index allows marketers to track overall campaign effectiveness at a glance. It helps identify top-performing and underperforming campaigns, prioritize resources, and improve strategic decision-making. ## How it is calculated The index is calculated by dividing the actual performance metric by the expected or baseline performance. It can be customized based on goals – such as ROI, CTR, or conversions – depending on your business objective. ## Good and bad values ## A good value A good Campaign Performance Index is above 100, meaning the campaign has exceeded expectations. The higher the number, the better the campaign has performed relative to its target. ## A bad value A Campaign Performance Index below 100 suggests the campaign fell short of its goals. This may point to targeting issues, weak messaging, or inefficient spending. ## Do Use these tips to track, improve, and act on Campaign Performance Index insights effectively. 1. 01 ### Set clear baselines Establish realistic campaign benchmarks based on historical performance or strategic targets to ensure accurate comparisons. 2. 02 ### Monitor KPIs in real time Regularly review campaign data so you can respond quickly to underperformance and reallocate budgets if needed. 3. 03 ### Align goals across teams Ensure marketing and sales teams agree on success metrics to avoid misalignment when calculating performance. ## Avoid 1. Don’t base the index on arbitrary numbers or incomplete data. Inconsistent baselines, misaligned KPIs, or ignoring context can result in misleading conclusions. ## Related metrics ## Related metrics you might be interested in [Click-Through Rate (CTR)`= (Total Clicks ÷ Total Impressions) × 100`](/metrics/click-through-rate) [Conversion Rate`= (Total VisitorsConversions​) × 100`](/metrics/conversion-rate) [Landing Page Performance](/metrics/landing-page-performance) [Return on Ad Spend (ROAS)`= Revenue Generated from Ads / Cost of Ads`](/metrics/return-on-ad-spend) ## Related articles ## Articles that use Campaign Performance Index [tracking · 7 free UTM builders for tracking your marketing campaigns · Oct 26, 2026](/blog/articles/track-your-marketing-campaigns-with-7-free-utm-builders) [google sheets tips · How to use INDEX MATCH in Google Sheets: formula, examples and errors · Oct 2, 2026](/blog/articles/index-and-match-google-sheets) [marketing · Mastering marketing efficiency ratio (MER) for improved campaign performance · Apr 8, 2026](/blog/articles/mastering-marketing-efficiency-ratio) ## Customer stories ## Learn how teams ship analytics faster Organizations that scaled analytics without scaling headcount [All case studies →](/blog/success-stories) [Pürblack · "For 10 years I was blind."
