Marketing metrics & formulas explained

Clear definitions and formulas behind the calculators. Use these as learning references.

Marketing ROI

ROI = ((Revenue − Marketing Cost) / Marketing Cost) × 100

Return on investment expresses profit relative to what you spent on marketing. Marketers use it to compare the efficiency of campaigns and channels.

ROAS

ROAS = Revenue / Ad Spend

Return on advertising spend shows revenue generated per unit of ad spend. A ROAS of 4 means four units of revenue for each unit spent on ads.

CPC, CPM & CTR

CPC = Spend / Clicks · CPM = (Spend / Impressions) × 1000 · CTR = (Clicks / Impressions) × 100

These advertising metrics describe cost efficiency and audience response. CPC is cost per click, CPM is cost per thousand impressions and CTR is the click-through rate.

CPA & Conversion Rate

CPA = Spend / Conversions · Conversion Rate = (Conversions / Visitors) × 100

CPA is the average cost to generate a conversion; conversion rate is the share of visitors who complete a desired action.

CAC & CLV

CAC = (Marketing + Sales) / New Customers · CLV = Avg purchase × Frequency × Lifespan

Customer acquisition cost and customer lifetime value help you understand unit economics. CLV here is an estimate based on your inputs.

UTM parameters

utm_source, utm_medium, utm_campaign, utm_term, utm_content

UTM parameters are tags added to a URL so analytics tools can attribute traffic to specific campaigns, sources and mediums. Values should be encoded correctly.

Keyword density

Density = (Keyword occurrences / Total words) × 100

Keyword density describes how often a term appears in text relative to total words. It is a descriptive measure and not a direct ranking factor.

Flesch Reading Ease

206.835 − 1.015 × (words/sentences) − 84.6 × (syllables/words)

A readability estimate where higher scores indicate easier reading. It is tuned for general English and should be treated as an estimate.
