How to use this calculator

  • Enter sleep hours for each day.
  • Set your target sleep per night.
  • Calculate to see average sleep, sleep debt, variation, and score.

What the result means

The result shows both total sleep and consistency, because large daily swings can reduce recovery even when the average looks acceptable.

Weekly sleep = sum of seven days. Average sleep = weekly sleep ÷ 7. Sleep debt = target×7 - actual weekly sleep.

Sleep needs vary. This calculator is a lifestyle estimate, not a diagnosis.

Example calculation

If you sleep 47 hours with an 8-hour nightly target, weekly sleep debt is 9 hours and average sleep is 6.7 hours.

Tips for better results

  • Prioritize consistent bedtime and wake time.
  • Reduce the lowest sleep nights first.
  • Do not rely only on weekend catch-up sleep.
  • Use sleep debt as a weekly warning signal.
