About Focus Time Ratio Calculator

Focus time ratio is uninterrupted deep work as a share of total working hours. For roles whose value comes from analysis, design or writing, a ratio below 25% means the calendar is preventing the job from being done, regardless of how many hours are worked.

Formulas

Focus time ratio

Focus % = Deep work hours / Total work hours x 100

Fragmented share

Fragmented % = (Meeting hours + Admin hours) / Total work hours x 100

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

What counts as deep work?

Blocks of at least 60-90 minutes with no meetings or interruptions. Three twenty-minute gaps do not add up to an hour of deep work.

How do I increase it?

Block it in the calendar as a recurring commitment, declare meeting-free periods at team level, and consolidate meetings into designated days.
