Free calculators for the metrics that actually matter
Five calculators for the SaaS numbers founders, finance leads, and operators get asked about. Each one runs in your browser, shows the formula, and includes industry benchmarks so the result is more than just a number.
CAC Calculator
What it actually costs to acquire a customer once you count all of sales and marketing, not just the ad spend.
Calculate CAC →LTV Calculator
Customer lifetime value with gross margin baked in, so the number you compare to CAC is honest.
Calculate LTV →MRR Calculator
Monthly recurring revenue with the four standard components: new, expansion, contraction, churn.
Calculate MRR →Churn Rate Calculator
Customer churn and revenue churn separately, because they tell you different things about the business.
Calculate churn →Rule of 40 Calculator
Growth rate plus profit margin. The benchmark VCs and operators use to decide whether a SaaS is healthy.
Run Rule of 40 →More on the way

Calculators are great for one-off math. For weekly, monthly, or quarterly review, you want the numbers updating themselves. clariBI pulls live data from Stripe, HubSpot, Google Analytics, your CRM, and the rest of your stack, then computes CAC, LTV, MRR, churn, and the rest on a fresh dashboard.
