Death Date 3000 is a free online life expectancy calculator that estimates when you might die based on your age, sex, and lifestyle habits — smoking, exercise, diet, sleep, alcohol, and more — then breaks down exactly which factors are estimated to be helping or hurting your number. It's built as a retro arcade-styled novelty tool, grounded in real published research on each factor.
No — and it's not trying to be. This is a novelty tool that applies rough, illustrative adjustments to a national life expectancy baseline based on your inputs. It's grounded in real research on each factor, but it can't predict an exact date for any individual. Think of it as an entertaining way to see which habits matter most, not a medical or actuarial prediction.
We start with a national life expectancy baseline based on your sex, then apply estimated year adjustments for each lifestyle factor you enter — smoking, exercise, diet, sleep, and more — based on published research on each one. Add them up and you get your result, broken down factor by factor so you can see exactly what's helping or hurting.
Smoking status has the single largest documented effect, followed by physical activity level and maintaining a healthy weight. Alcohol use, sleep quality, and chronic stress also matter, but generally carry smaller effects than the top few. We break this down in more detail, ranked by evidence strength, on the blog: How to Add Years to Your Life, Ranked.
No. Everything you type into the calculator stays in your browser and is never sent to any server. Refreshing the page clears it completely. Your only saved preference is your appearance (dark/black/light theme), which stays on your device.
No. This is an entertainment tool. For real health guidance, talk to a doctor. For anything related to insurance, retirement planning, or other financial decisions, talk to a qualified professional. Don't make real decisions based on a retro website with a pixel skull on it.
Quick mode only asks for age, sex, smoking, and exercise — a fast result with limited info. Full mode adds height, weight, alcohol, diet, sleep, stress, family history, checkups, and risk behaviors for a more complete (though still illustrative) picture. Quick mode results clearly note that they're based on limited information.
Yes — there's a KG/CM and LB/FT toggle right above the form fields, and another copy of it in Settings. Switch anytime; the calculation adjusts automatically either way.
If you changed any of your inputs, the result reflects that. If your inputs were identical, your result should be identical too — the calculation is deterministic, not randomized, so the same answers always produce the same result.
