Benchmark, model, and optimize with confidence

CROIndex is a free collection of marketing calculators, benchmarks, and decision tools designed to help marketers benchmark performance, model scenarios, and understand the business impact of key metrics.

Every tool is built around one idea: a single page, a single number, a single decision. Enter your inputs, read the result against real benchmarks, and see what each lever is worth before you act. No accounts, no paywalls, no fluff.
