Vaping Nicotine Intake Calculator
Estimate your daily nicotine from vaping, a rough cigarette-content comparison, and what the e-liquid costs you.
How it works
Nicotine/day = mL/day × strength (mg/mL) · Cigarette equivalent = nicotine/day ÷ nicotine per cigarette · Cost/day = (mL/day ÷ bottle mL) × bottle price
Your daily nicotine from vaping is simply the volume of e-liquid you use multiplied by its strength in mg/mL. Comparing that to cigarettes is inherently rough: a cigarette contains far more nicotine than it actually delivers to you, and vaping absorption differs too — so the cigarette figure here is a content-to-content ballpark, not a measure of what your body absorbs. The cost side is straightforward: your daily fraction of a bottle times its price.
Worked example
Using 3 mL a day of 20 mg/mL liquid gives 3 × 20 = 60 mg of nicotine daily. Against a 12 mg-per-cigarette content, that is 60 ÷ 12 ≈ 5 cigarettes worth. A $15 bottle of 30 mL costs (3 ÷ 30) × $15 = $1.50 a day, about $547 a year.
Frequently asked questions
Is the cigarette equivalent accurate?
It is a rough guide only. Cigarettes contain much more nicotine than they deliver, and vaping delivers a different fraction again, so this compares nicotine content rather than what you actually absorb. Use it for perspective, not precision.
How do I know how much e-liquid I use?
Track how long a bottle lasts: a 30 mL bottle used over 10 days is about 3 mL per day. Refillable tanks make this easier to estimate than disposables, where you can use puff-count ratings instead.
Is nicotine itself harmful?
Nicotine is highly addictive and can affect the developing brain and cardiovascular system, though most smoking-related disease comes from combustion products rather than nicotine alone. Reducing or quitting nicotine is the safest path — seek support if you want to stop.
