Marketing & Ads Calculators

Work out ad spend, return on ad spend, cost per click and campaign budgets before you spend a dollar. These calculators turn rough guesses into numbers you can plan a campaign around. The ad metrics cover CPC, CPM, CTR, CPA, ROAS and break-even ROAS, plus an ad budget calculator, a Facebook ads cost estimator and a Google Ads budget planner. The business metrics go further: cost per lead, conversion rate, customer lifetime value, customer acquisition cost, the LTV to CAC ratio, churn rate, retention rate, engagement rate — including an influencer engagement rate — and email open rate. Testing tools include an A/B test significance calculator and a sample size calculator, so you know how long an experiment needs to run before the result means anything. There are also the planning tools marketers reach for between campaigns: marketing ROI, a lead funnel calculator, average order value, a Net Promoter Score calculator, an ad copy character counter for Google and Meta limits, a rule-based headline analyzer and email subject line tester, and a content calendar template. For implementation, a Meta Pixel event code generator, a GA4 event snippet generator and a GTM dataLayer snippet generator produce the tracking code to paste into a site. Small businesses and freelancers use these numbers to decide whether a campaign is worth running at all — and every figure is computed locally, free, with no account.
