Productivity Score Calculator

Deep work score is calculated as min(100, (deepWorkHours / 4) × 100) before applying its 25% weight, so 4 hours is treated as the ceiling — a benchmark drawn from Cal Newport's writing on deep work as the elite standard for focused, cognitively demanding output in a single day. Logging 6 or 8 hours of deep work won't push that specific component any higher than logging exactly 4.

It compares your entered distraction count against an expected baseline of about 5.5 distractions per hour times your total work hours, which approximates research on average knowledge-worker interruption frequency. If your actual count is below that expected baseline the focus score rises toward 100; if it's above baseline, the score falls, calculated as 100 minus half your distraction ratio (capped at 0-100).

Not entirely — the time efficiency calculation treats deep work hours as fully productive, then adds half credit for whatever remaining work time isn't consumed by deep work or meetings (shallow work), and zero credit for meeting time itself. So a day heavy on meetings will show lower time efficiency and higher wasted hours even if those meetings were genuinely valuable, since the model has no way to distinguish productive collaboration from unproductive meeting time.

The letter grade is a direct threshold on the final 0-100 composite score: 90+ is A, 75-89 is B, 60-74 is C, 40-59 is D, and anything below 40 is F. Since the composite blends six weighted factors, the same letter grade can come from very different underlying profiles — for example, strong task completion offsetting a weak focus score, or vice versa.
