Enter your monthly traffic, conversion rate, average order value, gross margin, current page load time, target load time, and your best estimate of revenue loss per extra second. The calculator estimates how much monthly and yearly revenue slow pages may be costing you, along with the gross profit you could recover by speeding things up.

Add traffic and ecommerce inputs

Use monthly visitors, conversion rate, and average order value to estimate baseline revenue.

Enter current and target load times

The gap between them is the amount of latency you are trying to remove.

Adjust the elasticity assumption

Set your estimated revenue loss per extra second based on tests, analytics, or a reasonable benchmark.

Review what is at stake

Use the monthly, daily, and annual recovery estimates to prioritize performance work.

Häufig gestellte Fragen

Is the loss-per-second number universal?+

No. It varies by device mix, intent, vertical, and funnel stage. Replace the default with your own benchmark if you have one.

Can I use this outside ecommerce?+

Yes. As long as you can estimate conversion value, you can adapt it for SaaS trials, lead gen, or bookings.
