How long do vapes last? Puff count to days calculator
A 600-puff vape lasts 6 days at 100 puffs a day and under 3 days at the 225 puffs a day measured in vapers; a 5,000-puff device lasts 50 days at 100 a day. Formula: the rated puff count divided by your puffs per day. Rated counts come from machine puffs, so treat the result as a ceiling.
How long will your vape last? Calculator
Enter the puff count printed on the device and your puffs per day. The result updates as you type; the worked example and the table further down cover the common cases without it.
Count your puffs, then come back
Puff Counter logs each puff in one tap and shows your daily count, so the number you enter above is real. Free on iPhone and Android.
How the numbers work
The formula: days = rated puff count ÷ your puffs per day. Weeks = days ÷ 7; months = days ÷ 30.
Worked example with the defaults: 600 rated puffs ÷ 100 puffs a day = 6 days. At the 225 puffs a day measured when a device recorded every puff, 600 ÷ 225 = 2.7 days. A 5,000-puff device: 5,000 ÷ 100 = 50 days, about 7.1 weeks; 5,000 ÷ 225 = 22 days.
The result is a ceiling. The rated count is the maker's figure for the liquid in the device, and lab puff testing has a standard machine puff of 55 ml over 3 seconds. Measured vapers puff for 3 to 4 seconds and often draw more than 100 ml, and each bigger puff turns more liquid into aerosol, so the liquid runs out before the count does. The next section has the measurements; there is no single correction that fits every device, which is why the calculator does not apply one.
How the rated puff count is measured
The number on the box is the maker's figure. The UK and EU rules behind these devices cap the liquid at 2 ml and the nicotine at 20 mg/ml, and the MHRA's guidance on them lists no puff count; trading standards officers used about 600 puffs as the count a 2 ml device gives and treated a label claiming more as a sign of an oversized tank, liable to seizure.
Lab testing of e-cigarettes has a standard puff: ISO 20768, taken from CORESTA method 81, draws 55 ml over 3 seconds every 30 seconds, a regime designed around early mouth-to-lung devices. On that regime, a pod its maker rated at about 200 puffs lost 4.4 mg of liquid per puff and gave 188 puffs from its 0.7 ml, so for a small pod the label and a 3-second machine puff land close together.
Real puffs are longer and bigger. Experienced vapers filmed in a 2013 study puffed for 4.2 seconds against 2.1 seconds for smokers, and used about 5 mg of liquid per puff: 62 mg in 13 puffs over 5 minutes, 219 mg in 43 puffs over 20 minutes. When 21 vapers carried a device that recorded every puff for 24 hours, the mean puff lasted 3.5 seconds. In a 2022 UK trial of a puff-recording device, run with its maker, 58 vapers logged 200,411 puffs over two months; the mean puff was 3.4 seconds and individuals ran from 0.9 to 6.9 seconds. A 2025 review of the topography studies sums it up: real use often exceeds 100 ml a puff and runs 3 to 4 seconds, past the standard regime.
The puff behind the label has also been shrinking. Divide the liquid by the count and you get the puff the label assumes: a 2 ml, 600-puff device assumes 0.0033 ml per puff, 300 puffs per ml. Disposables sold by US online stores averaged 3,265 rated puffs from 8.75 ml in 2022, 373 per ml, and 13,980 from 17.88 ml in 2024, 782 per ml or 0.0013 ml per puff, with labels up to 40,000. At the 1.18 g/ml of a typical liquid (the pod liquid in the 2022 pod study weighed 0.826 g per 0.7 ml), the 5 mg a measured vaper's puff uses is about 0.004 ml, and a 2025 lab test of 25 popular disposables measured 11 to 12 mg, about 0.01 ml, per 3-second puff. At 0.004 ml, 2 ml gives about 500 puffs and 17.88 ml about 4,500; at 0.01 ml the same volumes give about 200 and about 1,800. So a small device's label is roughly honest at the low end of that range and optimistic at the high end, and a big-count label can be three to eight times what a normal puff gets from the liquid. That is the gap the calculator leaves you to judge, because it depends on the device in your hand.
How many puffs a day is normal?
More than people think. In the 24-hour recording study, the mean was 225 puffs a day and individuals ranged from 24 to over 1,000, almost twice the 120 to 175 puffs a day that vapers report in surveys. In the 2022 UK trial, the group settled at about 250 puffs a day after the first day or two, with individuals from 5 to more than 400. So 100 puffs a day, the calculator's default, is on the low side, and the table's 200 and 300 columns are closer to measured use.
What those puffs are worth in nicotine is a different question: run your count through the puffs to cigarettes calculator, and see how many puffs are in a cigarette for why a vape puff is not a cigarette puff.
How long do 600, 2,500, 5,000, 10,000, 20,000 and 30,000 puffs last?
Days = rated puffs ÷ puffs per day. The 200 and 300 columns bracket the 225 puffs a day measured in vapers; rated counts are ceilings, so real devices run out sooner.
| Rated puffs | Days at 50 puffs a day | Days at 100 puffs a day | Days at 200 puffs a day | Days at 300 puffs a day |
|---|---|---|---|---|
| 600 | 12 | 6 | 3 | 2 |
| 2,500 | 50 | 25 | 13 | 8.3 |
| 5,000 | 100 | 50 | 25 | 17 |
| 10,000 | 200 | 100 | 50 | 33 |
| 20,000 | 400 | 200 | 100 | 67 |
| 30,000 | 600 | 300 | 150 | 100 |
A 30,000-puff label at 50 puffs a day is 600 days, about 20 months; at the measured 225 a day it is 133 days, and at a normal puff the liquid may give a third of the rated count. Only a count tells you which column is yours.
How long should a vape last?
As long as its rated puffs divided by your puffs per day, and usually less. A 600-puff device should last about 6 days at 100 puffs a day, 3 days at 200 and 2.7 days at 225; a 5,000-puff device 50 days at 100 a day and 22 at 225. If yours runs out well before that, either you puff more than you think, which a week of counting settles, or the label assumes a smaller puff than yours, which the section on how the rated count is measured explains. The rated count says nothing about nicotine: a 600-puff device at 20 mg/ml holds about 40 mg, and the puffs to cigarettes calculator turns your count into cigarettes.
Disposable vapes in the UK and elsewhere
The UK banned the sale and supply of single-use vapes from 1 June 2025, online and in shops, with or without nicotine; a vape counts as single-use if its battery cannot be recharged or it cannot be refilled. Reusable devices stay on sale under the same 2 ml tank and 20 mg/ml UK and EU limits, so the 600-puff figure lives on as a 2 ml pod. Elsewhere disposables remain common and have grown: among disposables sold by US online stores, the average rated count rose from 3,265 puffs in 2022 to 13,980 in 2024, and the average liquid volume doubled from 8.75 ml to 17.88 ml.
Questions people also ask
How long does a 5000 puff vape last?
About 50 days at 100 puffs a day, 25 days at 200 and 22 days at the 225 puffs a day measured when a device recorded every puff. That is the rated count divided by your daily puffs, and a ceiling: rated counts assume machine puffs, and for the average big-count label sold online in the US in 2024 the liquid gives about a third of the count at a measured vaper's puff, so expect fewer days.
How long do disposable vapes last?
Divide the rated count by your puffs a day. A 600-puff disposable, the UK format before the 1 June 2025 ban, lasts 6 days at 100 puffs a day and under 3 at 225. Disposables sold by US online stores averaged 13,980 rated puffs in 2024, 140 days at 100 puffs a day on paper, but those labels assume about 0.0013 ml of liquid per puff, a third of what measured vapers use, so expect about a third of that.
How long should a vape last?
Its rated puffs divided by your puffs per day, and usually less. At the 225 puffs a day measured in vapers, 600 puffs last 2.7 days, 2,500 last 11 days and 5,000 last 22. If yours runs out sooner, either you puff more than you think or the label's puff is smaller than yours. Count for a week and you will know which.
How long does a 600 puff vape last?
About 6 days at 100 puffs a day, 3 days at 200 and 2.7 days at 225. A 600-puff device holds 2 ml of liquid, the UK limit, and trading standards treated 600 as the count 2 ml gives. At 0.004 to 0.01 ml per puff measured in vapers, 2 ml is 200 to 500 puffs, so the 600 label is optimistic at best, and a heavy vaper empties it in two or three days.
How do I know when my vape is empty?
The vapor thins and the taste turns dry and burnt. That is a dry puff, as the vaping topography literature describes it: the coil fires before the wick is supplied with enough liquid, overheats, and gives an unpleasant burning taste that makes users shorten their puffs. Stop at the first burnt puff. A puff count tells you in advance: when your total nears the rated count, the end is close.
Count your real puffs first
The calculator is only as good as the puffs per day you enter, and that is the number people get wrong: measured use was almost twice what vapers report. Puff Counter logs each puff in one tap, in the app or from the small home screen widget, and shows today's count and your hourly pattern, so you can enter your real average instead of a guess. See how counting works.
When you want the count to go down, the Premium quit plan sets a daily limit from your own average and lowers it step by step to a quit date. Counting is free on iPhone and Android.
