📚 Marketing percentage calculators
This hub connects marketing lift, share-of-market, and stacked pricing stories to focused percentage tools on separate URLs.
Lift = ((after − before) ÷ before) × 100; market share = your slice ÷ defined market total × 100.
Use case: A/B summaries, promo pricing, share-of-voice proxies, and funnel conversion rates.
How to use this hub
This marketing hub links lift, share, funnel, and pricing percent tools—keep baseline and variant definitions consistent when reporting test results.
Given: Control CTR is 2.0%; variant CTR is 2.4%.
- Absolute lift = 2.4 − 2.0 = 0.4 percentage points.
- Relative lift = (2.4 − 2.0) ÷ 2.0 × 100 = 20%.
Answer: Report both points and relative lift so stakeholders see scale and percent change.
Common mistakes: Mixing percentage points with relative percent change, changing the market denominator between periods, or stacking discounts additively.
Which tool for A/B test lift?
Use percentage increase or change when both values share the same baseline definition.
How do I report market share?
Use the market share calculator and keep the total market definition fixed across periods.
Can I chain promo discounts?
Use successive percentage for stacked markdowns; do not add discount rates directly.
