What is slow speed costing your WooCommerce store?

Enter your monthly revenue and your current LCP or pagespeed score. The calculator estimates how much revenue you’re likely leaving on the table every month – and what realistic speed work could recover.

Based on industry data, a one-second slowdown can cut conversions by up to 7%. The math here uses conservative public benchmarks, not vendor marketing.

Looks like your store is in great shape, no major speed leak detected.

These calculations work best for stores doing $10K+ in monthly revenue. Once you scale up, come back, and I’d be happy to look at your store.

Want a real audit instead of a rough estimate?

The calculator gives you a directional number from public benchmarks. A real audit looks at your actual Core Web Vitals, your hosting stack, your plugins, and your funnel.

How the math works

The calculator uses conversion-rate-vs-page-speed benchmarks from public industry research (Google, Deloitte, Akamai, and others), adjusted conservatively for WooCommerce-specific patterns. It assumes your traffic and average order value stay constant and only the conversion rate moves with speed.

For a precise number on your own store, you need a real audit against your live traffic.
