Productivity score calculatorNot how busy you were.
How much of it counted.

Most productivity scores measure activity, which is the easiest thing to count and the least useful. Hours logged and tasks closed both rise during a week spent entirely on the wrong things, so a score built from them rewards a busy week that produced nothing — and quietly punishes the week you spent on one hard problem and solved it.

A mixed week

The weakest term was “actually rested” (1 day off), which cost you 2 points.

✦ How to use it

Three things that make it work.

1
Score last week, not this one

A week in progress is scored on intention. A finished one is scored on evidence.

2
Count finished, not started

The completion ratio is the heaviest term here, and it is the one that is easy to inflate by counting things that are nearly done.

Watch the trend

One week is noise. Four weeks in a row is a system telling you something.

This weights differently. Finishing what you planned counts heaviest. Deep work hours count. Interruptions and context switching count against, because they are what turns available time into unusable time. Sleep is in here because it is upstream of everything else on the list.

Every weight is shown with the result, so you can disagree with a specific one rather than with a number.

✦ The limit

An answer is not a record.

This works something out and then forgets it. It cannot tell you whether the number moved, because it has no memory of the last time you ran it and no idea what you did in between. Every calculator on the internet has that limit, and if it has never bothered you then this one is yours for free for good.

EvyOS is the same structure with the work recorded against it. Send the result across and it becomes real goals, tasks or habits with their dates — then the next answer is computed from what actually happened rather than from what you remember typing.

Questions

Productivity score calculator, answered.

Seventy or above is a genuinely good week and most people's are in the forties and fifties. Chasing ninety every week is not the aim — the score is weighted so that a sustainable 70 beats an unsustainable 90 followed by a 30.
Because it is the only term that cannot be inflated by being busy. Hours, tasks closed and meetings all rise during a week spent on the wrong things; the ratio of finished to planned does not, which is why it is worth about a third of the score on its own.
Because it is upstream of every other line. Under six hours reduces the deep-work hours available, the completion rate and the ability to hold context, so scoring it separately is how you see the cause rather than only the three symptoms.
No. Work is lumpy and a single week is mostly noise. Four in a row in the same direction is a system telling you something, and the weakest term will usually have been the same one each time.
Download each week's result, or track the underlying numbers in EvyOS — the productivity dashboard template is built for exactly this and holds the history the calculator cannot.
