Quick answer: Divide the rated puffs by the puffs you take each day, then lower it for how you draw. A 25,000-puff disposable at 200 puffs a day lasts about 125 days if you get every puff on the box, about 75 days with typical 2-second puffs and about 38 days with long puffs or boost mode. Use the calculator below with your own numbers.

How the calculator works

The calculator divides the puffs you're likely to get by the puffs you take each day. The rated number on the box is the starting point; how you draw changes how much of it you actually get. A short, light puff uses less e-liquid and battery than a long, deep one, so heavier use means fewer real puffs.

Not sure how many puffs you take a day? Count for one ordinary day (tally marks on your phone work), then use that number. Most people guess low.

Days per device at full rating

This table is plain math: rated puffs divided by puffs per day, assuming you get every puff on the box. Real life is usually shorter (see the next section).

Rated puffs	100 puffs a day	200 a day	300 a day	500 a day
15,000	150	75	50	30
20,000	200	100	67	40
25,000	250	125	83	50
35,000	350	175	117	70
50,000	500	250	167	100
70,000	700	350	233	140
100,000	1000	500	333	200

Why real puffs are lower than the box

Manufacturers rarely publish exactly how they count puffs, and ratings generally assume short, light draws. In published lab tests, devices run with 2- to 3-second puffs gave roughly 12% to 57% of the box rating. Five things pull the real number down:

• Draw length. A 3-second draw uses far more e-liquid than a 1-second one.
• Boost or turbo mode. Higher power vaporizes more liquid per puff. Check the mode before you vape.
• Heat. Devices left in hot cars or direct sun can lose e-liquid and perform worse.
• Battery before liquid. On non-rechargeable devices the battery can run out before the e-liquid does.
• Long gaps. A device that sits half-used for weeks can taste flat before it's empty.

Here's how draw style changes days per device at 200 puffs a day:

Rated puffs	Short puffs (100%)	Typical (about 60%)	Long or boost (about 30%)
15,000	75	45	22
25,000	125	75	38
35,000	175	105	52
50,000	250	150	75
70,000	350	210	105

Picking a puff count that fits your week

Use your days-per-device number to choose a size, not the biggest number on the shelf:

If one device lasts you…	Consider
Under a week	A higher-puff or refillable-pod device, so you reorder less
1 to 3 weeks	Mid-range devices (20,000 to 35,000 puffs)
More than a month	A smaller device; very high-puff devices can taste flat before they're finished

Compare real specs side by side in our disposable vape spec database.

Making a disposable last longer

• Take shorter, lighter draws.
• Use eco or normal mode instead of boost when the device has modes.
• Keep it out of hot cars and direct sun.
• Lock it in your bag so it doesn't fire by accident (if it has a lock).
• On rechargeables, charge before the battery is completely flat.

Frequently asked questions

How long does a disposable vape last?

It depends on the rating and your use: a 25,000-puff device at 200 puffs a day lasts about 125 days at full rating, and fewer days with longer draws.

How many puffs a day is normal?

It varies widely by person. Count one ordinary day to get your own number rather than relying on an average.

Why does my vape run out before the puff count?

Longer draws, boost mode, heat and the battery running out first all reduce real puffs below the box number.

Are puff counts on the box accurate?

They're a maximum under light use. Published lab tests found real counts well below the box with longer puffs.

Does boost mode use more puffs?

Yes. Higher power vaporizes more e-liquid per puff, so the device empties faster.

How many devices will I need a month?

Divide 30 by your days-per-device number; the calculator does this for you.

Does a bigger puff count always mean better value?

Not always. If a device lasts you months, the flavor can fade before it's empty.

How do I count my puffs?

Tally them for one normal day on your phone, or use the puff counter if your device has a screen.

Does heat affect how long a vape lasts?

Yes. Keep devices out of hot cars and direct sun.

Can I make my disposable last longer?

Shorter draws, eco mode, cool storage and locking it in your bag all help.

Is the calculator exact?

No. It gives an estimate based on your inputs and rough puff-style percentages based on published lab tests.
