How the WHO-5 Calculator Works

The WHO-5 Wellbeing Index is a five-item questionnaire developed by the World Health Organisation and validated in clinical studies across more than 30 countries. Each item asks how often in the past two weeks you experienced a positive mental state, rated on a scale from 0 (at no time) to 5 (all of the time).

Your raw score — the sum of all five items — ranges from 0 to 25. This calculator multiplies by four to produce a percentage score from 0 to 100, which is the standard WHO-5 reporting format.

The Formula

WHO-5 Score = Sum of 5 items × 4

Tips to Improve Your WHO-5 Score

The five items map directly to actionable areas. If you scored low on feeling calm and relaxed, breathing techniques like box breathing can help within days. If energy was the issue, sleep consistency is typically the highest-leverage intervention. If you felt isolated, even one meaningful social interaction per week produces measurable wellbeing benefits.

For a structured approach, see our guide on creating a personal wellbeing plan — it uses WHO-5 scores as the baseline.

Limitations

The WHO-5 measures recent positive mood states, not the full spectrum of mental health. It screens effectively for depression but does not assess anxiety, personality disorders, or situational adjustment. A low score is a signal to seek professional assessment, not a diagnosis.

Frequently Asked Questions

What is the WHO-5 Wellbeing Index?

A five-item questionnaire developed by the WHO that measures subjective psychological wellbeing. It scores 0–100 and is one of the most widely used wellbeing instruments in clinical research.

What does a score below 50 mean?

Scores below 50 indicate low wellbeing and are used as a screening threshold for depression. This doesn't diagnose depression but suggests a professional assessment is worthwhile.

How often should I retake the WHO-5?

Every 4 weeks is typical for personal tracking. In clinical settings, monthly retesting is standard practice.

Is the WHO-5 validated?

Yes. It has been validated in over 30 languages with strong sensitivity (83%) for detecting major depression as a screening tool.

What should I do if my score is very low?

Please speak with a healthcare professional or mental health provider. If you feel unsafe or are in crisis, contact your local emergency services immediately.
