Frequently Asked Questions
How accurate is the money-saved estimate?▾
The calculator multiplies your per-cigarette cost by the number of cigarettes you would have smoked since your quit date. Accuracy depends on how consistent your pre-quit smoking and pack price were.
How is "life regained" calculated?▾
Research published in the BMJ (2000) estimates that each cigarette shortens a smoker's life by roughly 11 minutes on average. We multiply that by the number of cigarettes avoided. It's a rough estimate, not a medical prediction.
When do health benefits start?▾
Within 20 minutes of quitting, your heart rate and blood pressure begin to drop. Within 12 hours, carbon monoxide levels in your blood return to normal. Benefits continue for years — see the milestones panel for details.
Does this work if I vape or use nicotine replacements?▾
This calculator is focused on traditional cigarettes. The money-saved math still works if you enter your equivalent cost, but the health timeline assumes you've stopped inhaling combusted tobacco.
