Our Sleep Calculator gives you precise, science-backed answers by calculating the exact number of hours you need, the ideal bedtime, and the best wake-up time. It uses your natural 90-minute sleep cycles to ensure you wake up refreshed instead of feeling heavy, tired, or disoriented.
Just enter your bedtime or preferred wake-up time and the tool instantly shows how much sleep you should get, how many hours of sleep you actually got, and how much sleep you still need. You’ll also receive four optimized sleep schedule options that maximize deep, restorative sleep and support better focus, mood, and energy.
Whether you want to fix your sleep routine, recover from sleep debt, improve sleep quality, or simply understand your real sleep needs, this calculator gives you fast, accurate, personalized results without the guesswork.
What Is the Sleep Calculator?
The Sleep Calculator helps you find the best time to sleep or wake up by using your body’s natural 90-minute sleep cycles. Each cycle includes light sleep, deep sleep, and REM sleep. Waking up in the middle of a cycle can leave you groggy, but the Sleep Calculator helps you avoid that by showing the optimal times to wake up feeling fully rested.
How Does It Work?
Our Sleep Calculator is simple to use and provides instant, accurate results.
Two Ways to Calculate Your Sleep:
- “I Want to Go to Bed At…” – Enter your bedtime, and we’ll show the best wake-up times.
- “I Want to Wake Up At…” – Enter your desired wake-up time, and we’ll tell you when to fall asleep.
To get precise results, you’ll also select your age and gender. This allows the calculator to adjust recommendations based on your sleep needs.
What You’ll Get:
- 4 Recommended Sleep Time Options (so you can choose what works best for your routine)
- Hours of sleep and number of sleep cycles for each option
