How to use this calculator

  • Enter the total deep work hours you want to complete.
  • Choose a session length and recovery break.
  • Add your available focus time per day and energy level.
  • Use the score to decide whether the plan is sustainable.

What the result means

A sustainable deep work plan balances total target time, session length, recovery breaks, and daily capacity. Low scores indicate fatigue risk or an unrealistic schedule.

Sessions = Target Time ÷ Session Length; Total Time = Target Time + Breaks; Fatigue Index = Daily Load, Session Count, and Energy Adjustment

Longer sessions can work well, but only if recovery time and energy are sufficient.

Example calculation

A 12-hour target with 90-minute sessions requires 8 sessions. With 15-minute breaks, total planned time is about 13.75 hours.

Tips for better results

  • Use 60 to 90 minutes for demanding work.
  • Place the hardest session first.
  • Keep breaks away from social media.
  • Stop before quality collapses.
