How Long Will You Live? This Free Tool Estimates Your Life Expectancy Based on Your Daily Habits — The Result Might Surprise You
Most people assume they'll live to their late 70s or early 80s. But researchers who tracked over 500,000 adults found something surprising: daily habits — not genetics — account for up to 60% of the difference in how long people live.
That means two people born in the same year, in the same country, with similar family history can have life expectancy estimates that differ by over a decade — based entirely on choices they make every day.
The free calculator below analyses 8 of those key factors and gives you a personalised estimate in under 60 seconds. No sign-up. No email required.
Why Your Daily Habits Matter More Than You Think
A landmark study published in Nature Medicine identified seven lifestyle factors that together can shift life expectancy by up to 24 years. These aren't rare medical conditions or genetic disorders — they're things like how long you sleep, how often you move, and how much stress you carry.
The calculator on the next page uses those same evidence-based factors to give you a personalised picture. It's not a medical diagnosis — but it often reveals things people hadn't considered about their own routines.

- Sleep quality and duration
- Physical activity level
- Diet and eating habits
