About Marketing Calculators

Marketing Calculators is an independent educational website. We build free, fast calculators and plain-language reference pages about marketing and advertising metrics: CPM, CTR, CPC, CPA, ROAS, break-even and target ROAS, Google Ads budgets, impressions and reach, customer acquisition cost, customer lifetime value, LTV:CAC, churn and retention, MRR and ARR, marketing ROI, conversion rates, sales funnels, social media engagement rate and earned media value.

What we do

  • Calculators that show their working. Every tool prints its formula, a worked example and the intermediate numbers, so you can check the result against your own spreadsheet. The arithmetic is covered by automated tests with hand-worked answers.
  • Definitions from the people who bill you. CPM, CTR, CPC, conversion rate, cost per conversion, ROAS, target ROAS and budget rules are taken from Google Ads, Microsoft Advertising and Meta help documentation, linked and dated on each page.
  • Customer economics from published research. Lifetime value, retention, churn, ARR and retention-rate definitions come from peer-reviewed marketing research, open textbooks and public companies’ SEC filings, not from vendor blogs.
  • No selling. We do not sell products, we do not link to sellers, and we do not accept payment for reviews or placements.

Marketing Calculators is run by a small independent editorial team based in Türkiye. We are not affiliated with Google, Microsoft, Meta, Instagram, TikTok, YouTube, LinkedIn, Amazon, the IAB, the MRC, AMEC, the FTC or any agency, ad network, analytics or software vendor.
