How it works
How does the Website Speed Revenue Calculator work?
If each extra second of load time loses a share of conversions, making the page faster recovers them. The loss per second is your assumption; studies disagree, so start low and test.
- Each second saved recovers conversions compounding: lift = 1 ÷ (1 − loss)^seconds − 1.
- Revenue = visitors × conversion rate × order value.
- Use your real Largest Contentful Paint (LCP) from field data (e.g. Search Console) for current load time.
Worked example
60,000 visitors, 1.8% conversion, ₹1,800 orders (₹19.4 lakh a month). Cutting LCP from 4.2 to 2.5 seconds at an assumed 4% conversions lost per second lifts conversion by 7.2% (to 1.93%), worth about ₹1.4 lakh a month.
Limits
LCP measures when the main content renders, not full page load. The loss-per-second figure is an assumption; measure after a speed release.
