Happiness Calculator
Decades of well-being research keep landing on the same handful of levers. Enter six everyday numbers and see how your life lines up with what the studies say matters most — and which small change would move the needle furthest. Relationships carry the most weight here, because that’s what the evidence says.

Happiest Cities →The six levers — and why these
None of these is the whole story, and a number can’t capture a life. But across large studies, these six keep showing up as things that (a) genuinely move well-being and (b) you can actually change. The score weights relationships most heavily, because the longest-running study of adult life found good relationships to be the strongest predictor of a happy, healthy life — well above money.
How it’s scored & sources
- Social connection — 25%: hours of quality time with people you care about. Strong relationships are the top predictor of long-term happiness (Harvard Study of Adult Development, Waldinger & Schulz).
- Sleep — 15%: nightly hours, best around 7–9 (CDC; sleep-and-mood research).
- Exercise — 15%: active days per week; even a few 30-minute sessions lift mood and lower depression risk.
- Commute — 15%: shorter is better; long commutes are a well-documented drag on daily well-being (Stutzer & Frey, 2008).
- Income adequacy — 15%: well-being rises with income up to a comfortable level, then flattens (Kahneman & Deaton, 2010; Killingsworth, 2021).
- Time in nature — 15%: roughly two hours a week outdoors is linked with better health and well-being (White et al., 2019).
- A reflective lifestyle tool, not a clinical or mental-health measure. If you’re struggling, talking with a professional or someone you trust can really help.
Frequently asked questions
Why is money only 15%?
Because the research is consistent that income matters up to a point and then its effect on day-to-day happiness fades, while relationships, sleep, and movement keep paying off. We weight what the evidence weights.
