How to Calculate How Many Puffs in E-Liquid

How to Calculate How Many Puffs in E-Liquid

Vaping has become a popular alternative to smoking, and one question many vapers have is how to calculate how many puffs they can get from their e-liquid. Knowing this can help manage your vaping habits and plan your purchases better. In this article, we'll break down the process in simple and easy-to-understand steps.

Understanding E-Liquid

What is E-Liquid?

E-liquid, also known as vape juice, is the liquid used in vape devices. It typically contains nicotine, flavorings, propylene glycol (PG), and vegetable glycerin (VG). The nicotine content is often expressed in milligrams per milliliter (mg/ml).

Factors Affecting E-Liquid Consumption

Several factors influence how quickly you go through your e-liquid:

  1. Device Type: Different devices have different power levels and efficiency.
  2. Coil Resistance: Lower resistance coils use more e-liquid.
  3. Vaping Habits: How often and how long you inhale.
  4. Nicotine Strength: Higher nicotine strengths might lead to fewer puffs since the user may take fewer puffs to satisfy their cravings.

Calculating E-Liquid Consumption

To estimate the number of puffs you can get from a bottle of e-liquid, you need to understand a few key concepts:

1. Bottle Size and Nicotine Strength

E-liquids come in various bottle sizes, typically ranging from 10ml to 120ml. Knowing the size of your e-liquid bottle is the first step. Additionally, knowing the nicotine strength helps to understand your consumption pattern.

2. Device Consumption Rate

Different devices consume e-liquid at different rates. On average:

  • A low-powered device (like a pod system) uses about 1-3 ml of e-liquid per day.
  • A high-powered device (like a sub-ohm tank) uses about 5-10 ml per day.

3. Average Puff Consumption

The average puff from a vape device uses approximately 0.15 ml of e-liquid. This can vary based on the device and personal habits, but it provides a good baseline for calculations.

Step-by-Step Calculation

Let’s go through the process step by step:

Step 1: Determine Your Daily Usage

First, estimate how much e-liquid you use in a day. If you're unsure, keep track of your e-liquid consumption over a few days and find the average. For example, if you use a pod system, you might use 2 ml per day.

Step 2: Find the Bottle Size

Check the size of your e-liquid bottle. Common sizes are 30ml, 60ml, and 120ml.

Step 3: Calculate Total Consumption

Divide the total amount of e-liquid by your daily usage to find out how many days your bottle will last.

Example: If you have a 30ml bottle and use 2ml per day: Days the bottle will last=30 ml2 ml/day=15 days\text{Days the bottle will last} = \frac{30 \text{ ml}}{2 \text{ ml/day}} = 15 \text{ days}

Step 4: Estimate Puffs per Day

Next, estimate how many puffs you take in a day. On average, a vaper takes around 200 puffs per day. This number can vary widely, so adjust based on your own habits.

Step 5: Calculate Puffs per Bottle

Now, multiply the number of days your bottle will last by the number of puffs you take per day.

Example: Total puffs per bottle=15 days×200 puffs/day=3000 puffs\text{Total puffs per bottle} = 15 \text{ days} \times 200 \text{ puffs/day} = 3000 \text{ puffs}

Adjusting for Different Devices and Habits

Higher Consumption Devices

If you use a high-powered device, your e-liquid consumption rate will be higher. Repeat the same calculations with your adjusted daily usage.

Example: For a sub-ohm tank using 7 ml per day and a 60 ml bottle: Days the bottle will last=60 ml7 ml/day8.57 days\text{Days the bottle will last} = \frac{60 \text{ ml}}{7 \text{ ml/day}} \approx 8.57 \text{ days} Total puffs per bottle=8.57 days×200 puffs/day1714 puffs\text{Total puffs per bottle} = 8.57 \text{ days} \times 200 \text{ puffs/day} \approx 1714 \text{ puffs}

Different Puff Rates

If you take longer or shorter puffs, your e-liquid consumption per puff will differ. Adjust the average puff consumption rate (0.15 ml) accordingly.

Example: If you find your average puff uses 0.2 ml: Puffs per ml=1 ml0.2 ml/puff=5 puffs/ml\text{Puffs per ml} = \frac{1 \text{ ml}}{0.2 \text{ ml/puff}} = 5 \text{ puffs/ml} For a 30 ml bottle: Total puffs per bottle=30 ml×5 puffs/ml=150 puffs\text{Total puffs per bottle} = 30 \text{ ml} \times 5 \text{ puffs/ml} = 150 \text{ puffs}

Tips for Managing E-Liquid Consumption

Monitor Your Usage

Keeping track of how much e-liquid you use can help you manage your consumption better. Use a log or an app to record your daily usage.

Choose the Right Device

Select a device that matches your vaping style and e-liquid consumption. Pod systems are generally more economical on e-liquid, while sub-ohm tanks offer a different experience but consume more.

Adjust Nicotine Strength

Higher nicotine strengths can reduce the number of puffs needed to satisfy cravings, potentially lowering your overall e-liquid consumption.

Maintain Your Device

Proper maintenance of your vape device ensures efficient e-liquid use. Clean your tank regularly, replace coils as needed, and ensure proper wicking.


Calculating how many puffs you can get from your e-liquid helps in managing your vaping habits and planning purchases. By understanding your device, daily usage, and puff habits, you can make more informed decisions. Follow the steps outlined above to estimate your e-liquid consumption and enjoy a smoother vaping experience. Happy vaping!
