What's your industry?
We pre-load sector benchmarks. You can still override every value in the next step.
Your business numbers
Rough estimates are fine — the ratios matter more than the absolutes.
How fast are you now — and where are you aiming?
We use LCP (Largest Contentful Paint) as the primary speed signal, measured in milliseconds on mobile.
Projected revenue impact
Three scenarios using different elasticity multipliers. The truth is usually somewhere in the middle.

Milliseconds make millions
4,500 retail and travel sites tracked for 4 weeks. A 0.1s improvement in mobile LCP drove +8.4% in retail conversions on average — we use the median (+0.35%/100ms) as the "expected" band.

Real-user LCP distributions from millions of Chrome installs. We pair your inputs with CrUX industry medians so you can sanity-check yourself against your sector.

400+ case studies published by retailers, SaaS and publishers. Top-quartile outcomes cluster around +0.5% per 100ms — our "aggressive" scenario. Amazon's original 100ms ÷ 1% finding sits here too.

Baseline monthly revenue
sessions × CR × AOV — your current monthly take. This is the number we lift against.
Delta steps
(LCP_current − LCP_target) / 100 — how many 100ms "steps" you'd gain. We cap improvements at +3.0% CR to stay realistic.
Apply the rate
revenue × (1 + steps × rate) — three rates, three scenarios. Year-over-year, not compounding month-on-month.
