Free calculators and reference pages for DTC operators. No email gate and no signup wall — every one of them computes in your browser. Each carries the formula it uses, the publisher and date behind every benchmark it quotes, and the denominator that figure was measured on.
- Add-to-cart rate calculator Your rate in two fields, then the rest of the funnel. Plus the four rival denominators — Shopify, Dynamic Yield and two GA4 metrics all measure this differently — and dated benchmarks. Last reviewed 28 July 2026
- Cart abandonment calculator Cart abandonment and checkout abandonment are two different numbers on two different denominators. Work out either, priced against your AOV, and place it beside Baymard's and Dynamic Yield's dated figures. Last reviewed 28 July 2026
- Average order value calculator Two fields give you the number, then revenue per session, revenue per customer and orders per customer. Placed against the only two sourced AOV benchmarks — and the mean-vs-median caveat both of them hide. Last reviewed 28 July 2026
- Free shipping threshold calculator Where to set the line, worked out from your own AOV, margin and shipping cost — the suggested band, the break-even, and the month it costs or earns you. Last reviewed 28 July 2026
- A/B test sample size calculator How much traffic a test needs before it can call anything, and how much less it needs when you test on the higher baseline. Last reviewed 28 July 2026
- A/B test significance calculator Four numbers give you the verdict, the p-value and the interval on the difference — plus the two integrity checks most calculators skip: a sample-ratio-mismatch test on your split, and a low-data guard. Last reviewed 28 July 2026
- Scroll depth benchmarks What the published scroll-depth figures actually measure, where the widely-quoted 53% came from, and why GA4 only reports 90%. Last reviewed 28 July 2026
- Ecommerce conversion rate calculator Your rate both ways — session-based and visitor-based — placed against four published benchmarks that don't measure the same thing, each with its basis and date. Last reviewed 28 July 2026
