Why this extension?

You know, there's always one more tutorial video to watch, but never enough hours before the exam.

It's 1 AM before your exam. You've got three 30-minute tutorials left:

At normal speed: 90 minutes total
You need to sleep in 70 minutes
At 1.5x speed... is that 60 minutes? 45?

Your tired brain struggles with the math while the clock keeps ticking. "Is this 60 minutes now? 45? Can I actually finish this and sleep?"

That's when I realized - in the crucial moments when every minute counts, we shouldn't waste mental energy on speed calculations. This extension was born from that midnight frustration.

User Reviews

Underrated extension for YouTube. Absolutely worth it.

Does exactly what I need and even considers the time reduced with SponsorBlock when SponsorBlock is used.

Is YT Playback Calculator Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

YT Playback Calculator requires a few sensitive permissions. Exercise caution before installing.
