Happiness Score Calculator
A single happiness number is most meaningful when it reflects what you actually care about. This calculator asks you to rate five common life domains (health, relationships, work or purpose, finances, and leisure) from 0 to 10, and to weight each by how important it is to you. It then computes a weighted average on the same 0 to 10 scale, along with a percentage. The result is a personal, self-rated snapshot, not a clinical measure, and it is fully transparent: change a rating or a weight and watch the score move.
Happiness score formula
Weighted sum = sum of (rating * weight) for each domain
Total weight = sum of weights
Weighted score = weighted sum / total weight
Percentage = weighted score / 10 * 100
Simple average = sum of ratings / number of domains
The weighted score divides the weighted sum of your ratings by the total weight, so domains you mark as more important pull the score toward their rating. The simple average ignores weights for comparison.
Happiness measurement context
- Many national wellbeing surveys use a 0 to 10 life-satisfaction scale.
- This is a self-rated, personal snapshot, not a clinical or official measurement.
- Weights let the score reflect your own priorities across life domains.
- Comparing the weighted and simple averages shows how much your priorities shift the result.
- Re-running it over time can reveal trends in how you rate different parts of life.
Happiness score: frequently asked questions
How is a happiness score calculated here?
You rate five life domains from 0 to 10 and assign each a weight reflecting how important it is to you. The score is the weighted average: each rating times its weight, summed, then divided by the total weight. The result is on the same 0 to 10 scale.
What do the domains represent?
The five domains are common areas of life satisfaction: health, relationships, work or purpose, finances, and leisure. You choose how much each one weighs, so the score reflects your own priorities rather than a fixed formula.
Is there an official happiness scale?
Several wellbeing surveys use 0 to 10 life-satisfaction scales, such as those described by national statistics agencies. This calculator uses that familiar scale but produces a personal, self-rated figure, not a clinical or official measurement.
Why are weights adjustable?
Because people value different things. A fixed equal weighting would not reflect that finances might matter more to one person and relationships more to another. Adjustable weights make the score yours.
What does the percentage output mean?
The percentage simply expresses your weighted score out of the maximum of 10, so a weighted score of 7.5 is 75%. It is a convenient way to see how close you are to your own top rating across all domains.
