Sedentary Time Risk Calculator

Work out sedentary time risk instantly with clear inputs, formula shown and shareable results.

About Sedentary Time Risk Calculator

Sitting time carries health risk partly independent of exercise, and the risk climbs steeply beyond about six hours a day. Both structured activity and simply breaking up the sitting help: around 30-40 minutes of moderate activity substantially offsets long sitting, and frequent standing breaks improve glucose handling regardless of total exercise.

Formulas

Excess sitting

excess = sitting hours - 6

Score

score = 8 points per excess hour, offset by activity and standing breaks

Worked example

With the default values below, Sedentary Time Risk Calculator returns Sedentary Risk Score of 6. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 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 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
This is an estimate from population-average equations, not a medical or diagnostic assessment. Individual results vary with genetics, training history and technique. Seek advice from a qualified coach or clinician before making significant changes to training.

Frequently Asked Questions

Does exercising cancel out a desk job?

Partly. Studies find 30-40 minutes of daily moderate activity offsets much of the risk from long sitting, but frequent breaks matter separately.

How often should I stand up?

Every 30 minutes ideally, even briefly. The frequency of breaks matters more than their length for glucose and lipid metabolism.
