Habit time cost calculator
Twenty minutes a day feels like nothing, yet it is over 120 hours a year — three working weeks. The tool turns a daily habit into hours, working days and concrete equivalents.
The number does not say the habit is bad. Rest and fun need hours too. The point is to see whether what you get back is worth the real size of the cost.
Frequently asked questions
How do I estimate the real minutes?
Do not guess. Your phone reports app time, and for everything else a week of paper notes is enough. Memory-based estimates usually run at half the truth.
Why eight-hour working days?
Because 120 hours means something different against a working day than against a calendar day. It is a unit you can compare with real projects.
Should I cut the habit entirely?
Halving it usually buys the same time back with far less frustration than an outright ban.
