Guides

Plain answers, with the sources shown and the limits stated.

These are the questions people actually ask about the arithmetic of quitting. Every figure traces to a named source, and every guide says where the numbers stop being measurements and start being extrapolation. The full model is on the methodology page, and you can run it yourself on the calculator.

Start here

• How many years do you get back when you quit smoking?
• Is it too late to quit smoking at 50?
• How many minutes of life does one cigarette cost?
• The best quit smoking apps, compared honestly
• A quit smoking app without a subscription
• A private quit smoking app with no account, checked rather than promised

Everything here is a motivational estimate built from population averages. It is not a prediction about you, it does not diagnose, treat or prevent any condition, and it is not medical advice. Talk to a doctor or a quitline about stopping smoking. In the US, that is 1-800-QUIT-NOW.
