O que me impressiona no marketing-rechner.com é que ele elimina o excesso de 'ferramental' para problemas simples. Em vez de abrir planilhas complexas ou ferramentas pesadas só para checar um CAC ou um Break-Even ROAS, você tem tudo ali, instantâneo e no navegador. O diferencial, para mim, foi a parte dos benchmarks — ter a conta feita é uma coisa, mas entender como esse número se posiciona frente ao mercado é o que realmente ajuda na tomada de decisão.
The biggest value here is that you don't have to choose between "free" and "accurate." Most marketers hit a wall where free tools lack real benchmarks, and paid tools require integration or expensive subscriptions before you even know if it's worth your time. Having 35+ calculators with real industry benchmarks and no signup barrier is genuinely rare. The "Marketing Cockpit" simulator piece especially solves a real problem - most people calculate CAC once and then guess on scaling decisions. Being able to instantly see how changes in AOV, margin, or purchase frequency shift your unit economics removes so much guesswork. The multi-currency and localization for DACH market also shows real understanding of needs beyond English-speaking SaaS teams. No data collection is the cherry on top - lets risk-averse finance teams use it without legal pushback. The glossary and guide articles also make it accessible to teams without MBAs doing their own marketing finance.
Hey everyone! 👋 I kept redoing the same ROAS, CAC and LTV:CAC math in scattered spreadsheets before every ad or pricing decision — so I turned it into a proper toolkit instead: 35+ free calculators for performance marketing, e-commerce and SaaS, each with a benchmark score and a worked example, not just a bare number. It's a solo project, currently fully in German and built for the DACH market (Germany/Austria/Switzerland) — but the calculators are logic, not language, so an English version is on the roadmap. Would love to hear which metric you wish existed, or what confused you on first use — happy to fix or add things quickly.
