The real numbers behind quitting
Money saved, health gained, life reclaimed.
Invest the savings and watch it grow
If you invest the $3,650/year you save by quitting into an index fund averaging 7% returns, after 20 years you'd have over $157,000. The savings compound as aggressively as the habit cost.
The healthcare cost savings
Smokers pay 15–30% higher health insurance premiums and face significantly higher lifetime healthcare costs. Quitting reduces your risk of 12+ types of cancer, heart disease, stroke, and COPD — illnesses that cost hundreds of thousands to treat.
The 5% per quit attempt rule
Each quit attempt gives a 5–7% success rate without support, and up to 35% with medication and counseling. Most successful quitters tried 8–14 times first. Every attempt is progress, not failure — the data shows persistence pays off.
How the Quit Smoking Calculator Works
Formula
Money Saved = Packs/Day × Pack Cost × Days Since Quit
Cigarettes Avoided = Packs/Day × 20 × Days Since Quit
Life Regained (days) = (Cigarettes Avoided × 11 min) ÷ 1,440Enter packs per day smoked
Use your average before quitting — 0.5 (10 cigs/day) to 3 packs.
Enter pack cost
The price you paid per pack, including tax. Prices range from $6–14 across US states.
Enter days since quitting
Day 1 to day 3,650 (10 years). Every day counts.

The 11-minutes-per-cigarette figure comes from a 2000 study published in the British Medical Journal by Doll et al., based on 50 years of data. It's a population average — individual results vary.
