Your Sleep Debt
Score in 30 Seconds
Enter how much sleep you actually got each night this week. We’ll calculate your cumulative debt and show you exactly how long recovery takes.
The science: Sleep debt is cumulative and real. Research shows losing just 90 minutes per night for a week reduces daytime alertness by 32% — and you can’t recover it all in one weekend. This calculator uses validated sleep science thresholds to score your deficit accurately.
