Pain Score Tracking Calculator

Work out pain score tracking instantly with clear inputs, formula shown and shareable results.

About Pain Score Tracking Calculator

Tracks change on a 0 to 10 numeric rating scale and compares it with the commonly used clinically important difference of two points or 30 percent.

Formula

Pain score change

Reduction (%) = (baseline - current) / baseline x 100; a fall of 2 points or 30% is the usual minimum clinically important difference

Worked example

With the default values below, Pain Score Tracking Calculator returns Reduction from baseline of 37.5%. 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.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

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

Frequently Asked Questions

Why 30 percent?

Trials in acute and chronic pain consistently find that around a third reduction is the smallest change patients call meaningful.

Are pain scales comparable between people?

No. They track change within one person rather than comparing severity between individuals.
