What Percentage of Users Leave a Slow Website?
Bounce rates increase 90% when page load goes from 1 to 5 seconds.
Data current as of February 2026
53% of mobile users will leave a website if it takes more than 3 seconds to load. According to Google’s research, over half of your potential customers abandon slow sites before they even see what you offer—and bounce rates increase by 32% when load time goes from 1 to 3 seconds.
Website speed isn’t just a technical issue—it’s a business issue. Google’s data shows that the probability of bounce increases 90% when page load time goes from 1 second to 5 seconds. (Google | 2023) For local businesses competing for customers, a slow website means lost revenue.
The stakes are even higher when you consider conversion rates. Sites that load in 1 second see an average conversion rate of nearly 40%. At 3 seconds, that drops to 29%. By 5 seconds, conversions have cratered. (Portent | 2024)
For context, the average mobile page load time in 2024 is 8.6 seconds—nearly triple the 3-second threshold where most users abandon. (Hostinger | 2025) Most small business websites are bleeding customers without knowing it.
Key Statistics at a Glance
Bounce Rate Increases Dramatically with Load Time
Google’s research shows bounce rate probability increases exponentially as page load time increases:

Actual Bounce Rates by Load Time
Pingdom’s analysis of millions of websites shows the actual bounce rates at different load speeds:
The difference is stark: a 5-second site has 5.4x the bounce rate of a 1-second site. (Pingdom | 2024)
How Load Time Affects Conversions
Bounce rates only tell part of the story. The real impact shows up in conversion rates:
Website conversion rates drop by an average of 4.42% for each additional second of load time (between 0-5 seconds). (Portent | 2024) A slight improvement in speed can meaningfully impact revenue.
Real-World Revenue Impact
Major companies have quantified the cost of slow load times:
Every 100ms of latency costs 1% of sales
