Marketing & Analytics Calculators

17 free tools for ROAS, CAC, LTV, CTR and more.

Reading Marketing Metrics Correctly

The 17 tools in this category cover the full marketing funnel: ad cost metrics at the top (CPM, CPC, CPL), conversion metrics in the middle (CTR, CR, cart abandonment), and unit economics at the bottom (CAC, LTV, ROAS, profit margin, marketing ROI). Knowing which metric to look at matters more than computing it: optimize ad budgets with ROAS, but measure business sustainability with your LTV:CAC ratio.

The A/B test calculator tells you whether the difference between two variants is real or just chance, using statistical significance (p-value and confidence level); if your sample is too small, do not trust the result. The customer retention tool quantifies why acquiring a new customer costs several times more than keeping an existing one. The UTM builder standardizes campaign links so Google Analytics tracks them cleanly.

Never interpret metrics without context: a ROAS above 4 is considered good in e-commerce, while a high-margin SaaS business can be profitable at 2. Evaluate industry averages against your own margin structure.
