Why we built SmokeCalc

Last reviewed: 2026-06-05

SmokeCalc started with a question. A friend had been smoking for fourteen years and was thinking about quitting — but every quit-smoking resource he found was either a clinical intervention (he did not need one), a nicotine replacement ad (he did not want one), or a government brochure full of population-level statistics that did not feel like they applied to him.

He wanted to know: how much is this actually costing me? Not in the abstract. His number, in his currency, given the way he actually smokes.

We built a calculator. It was simple — cigarettes per day, price per pack, year you started. The output was a number, in dollars, that made him put down the cigarette he was about to light. That number has been the spine of SmokeCalc ever since.

Our principles

SmokeCalc runs on a short set of principles. They are the same now as on day one. If we ever break one, that is when you should stop trusting the site.

  1. 01

    Free forever. No paywalls, no premium tiers.

    The calculators are the product. We monetize through unobtrusive ads and voluntary Ko-fi donations. We will never charge for a feature.

  2. 02

    No signup required.

    You can use every calculator with zero friction. The only data we hold is what you explicitly enter into the optional email companion.

  3. 03

    Evidence-based data.

    All health numbers come from CDC, WHO, NHS, American Lung Association, American Heart Association, American Cancer Society, and the British Medical Journal. Financial calculations use plain math — no hidden multipliers, no optimistic assumptions.

  4. 04

    No fear-based imagery or guilt-tripping copy.

    We show you your numbers. We let the math do the work. There are no pictures of diseased lungs, no shame-based messaging, no judgment.

  5. 05

    Privacy by design.

    Plausible Analytics only. No cookies, no cross-site tracking, no personal data collection. Your inputs stay in your browser.

How we handle health data

Every health claim on SmokeCalc is sourced. The 20-minute heart-rate drop, the 24-hour heart-attack-risk drop, the 1-year heart-disease halving, the 10-year lung-cancer halving, the 15-year full cardiovascular recovery — all of these are drawn from named studies and named health agencies.

We do not invent numbers. We do not round up to make a point. The 11-minutes-per-cigarette figure is from Shaw, Mitchell and Dorling, BMJ 2000 (320:53), which divided the 6.5-year smoker–non-smoker life-expectancy gap by an average lifetime cigarette count. The 40-year (Doll et al., BMJ 1994) and 50-year (Doll et al., BMJ 2004) British Doctors Study follow-ups are the basis for the lifetime-life-expectancy estimates. The "smokers die ~10 years earlier" figure comes from Jha et al., NEJM 2013, on U.S. National Health Interview Survey data. The health recovery milestones come from CDC, NHS, the American Lung Association, and the American Heart Association.

Where a number has uncertainty — and most do — we say so in the calculator. Where your individual result will differ from the population average, we say so too. The page is informational, not a substitute for a medical professional.

Data sources

  • CDC — Centers for Disease Control and Prevention
    US adult smoking rates, youth tobacco use, state-level tobacco economics.
  • WHO — World Health Organization
    Global tobacco prevalence, tobacco tax policy, MPOWER implementation.
  • NHS — UK National Health Service
    UK smoking rates, health recovery milestones, quitline information.
  • American Lung Association
    Health benefits of quitting, lung recovery timeline.
  • American Heart Association
    Cardiovascular recovery timeline, heart disease risk reduction.
  • American Cancer Society
    Cancer risk reduction over time after quitting.
  • British Medical Journal (BMJ)
    Shaw, Mitchell & Dorling 2000 ("Time for a smoke? One cigarette reduces your life by 11 minutes", BMJ 320:53); Doll et al. 1994 (40-year British Doctors Study follow-up); Doll et al. 2004 (50-year mortality follow-up).

Editorial process

SmokeCalc data is reviewed quarterly. Cigarette prices come from Campaign for Tobacco-Free Kids and Tax Foundation. State excise tax rates are sourced from the Tax Foundation state-cigarette-excise-tax-rate tracker, updated each January and July. Adult smoking prevalence comes from CDC STATE System. Quitline numbers and URLs come from the North American Quitline Consortium.

The last full data review for all 50 states + DC was completed on July 1, 2026. Each programmatic state page is regenerated from content/schema/us-states.ts at build time; changes to source data flow through within one deploy cycle.

Corrections: [email protected]. We fix user-reported errors within 48 hours.

Editorial standards

Every page is reviewed before publication. The review checks: (1) every number has a citable source; (2) no fear-based or shame-based language; (3) no promises of guaranteed success; (4) medical disclaimers are present where appropriate. Pages are re-reviewed annually or when a major study contradicts a number we publish.

If you spot an error — a typo, a wrong number, a broken link — please tell us. We fix user-reported errors within 48 hours.

What we will never do

  • Sell user data — to anyone, ever.
  • Charge for a calculator feature or build a premium tier.
  • Use scare imagery or guilt-based copy.
  • Show popups, interstitials, or forced registration walls.
  • Display tobacco brand logos or promote any nicotine product.
  • Inflate metrics or manufacture social proof.
