How Much Vape Juice Do You Need Per Week?

If you're wondering how much vape juice you need per week, there isn't one amount that works for everyone. Your weekly e-liquid consumption depends on your vape kit, coil resistance, wattage, puff length, vaping frequency and the type of e-liquid you use. 

As a general starting point, many adult vapers may use around 10ml to 30ml of e-liquid per week, while lighter MTL users may use less and heavier sub-ohm vapers may use considerably more. 

The easiest way to estimate your requirement is to understand how much e-liquid your particular setup uses each day. 

How Much Vape Juice Does the Average Vaper Use? 

Rather than relying on one "average" figure, it's more useful to look at different vaping styles. 

These figures are only a guide. Two people using the same vape can have completely different consumption depending on how frequently and how heavily they vape. 

For example, someone using a compact pod with a higher-resistance coil may only need one or two 10ml bottles per week, while a heavy sub-ohm user could go through 50ml or more during the same period. 

How Much Vape Juice Do You Need Per Day? 

Working out your daily consumption makes it much easier to estimate your weekly and monthly requirements. 

Simply multiply your average daily usage by seven. 

For example:

The table below provides a quick way to estimate how long common e-liquid quantities could last. 

These calculations are based simply on the amount of e-liquid available divided by your daily consumption. 

What Affects How Much Vape Juice You Use? 

Your device is one of the biggest factors affecting e-liquid consumption, but it isn't the only one. 

The main factors include: 

A compact pod used at low wattage can be significantly more economical with e-liquid than a powerful sub-ohm kit. 

Does Your Vape Kit Affect E-Liquid Consumption? 

Yes. Different types of vape kits produce different amounts of vapour and therefore can use e-liquid at very different rates. 

Compact pod devices such as the Geekvape Wenax Q Pro Pod Vape Kit, Geekvape Wenax Q Pod Vape Kit and Voopoo Argus G3 Vape Kit are designed around lower-powered pod-style vaping. 

A powerful device such as the Geekvape Aegis Legend III Vape Kit, when paired with a suitable sub-ohm tank and low-resistance coil, can consume considerably more e-liquid. 

This is why knowing your device type is important when estimating how much vape juice you'll need each week. 

MTL Vaping Usually Uses Less E-Liquid 

Mouth-to-lung (MTL) vaping generally uses lower power, tighter airflow and smaller amounts of vapour per puff. 

For example, the Aspire Nautilus 3 Vape Tank supports MTL vaping and can be paired with higher-resistance Nautilus coils. 

A setup using a 1.8Ω coil at around 10W–12W will generally use considerably less e-liquid than a sub-ohm coil operating at 50W or more. 

For a lighter MTL user, approximately 5ml to 15ml per week may be sufficient, depending on vaping frequency. 

MTL setups are commonly paired with 50/50 e-liquids, high-PG e-liquids or nicotine salts, depending on the coil and device manufacturer's recommendations. 

Does Coil Resistance Affect Vape Juice Consumption? 

Yes. Coil resistance and recommended wattage can have a significant effect on consumption. 

As a general rule: 

Consider the Vaporesso GTX Mesh Coil range. Different versions are designed for different power levels: 

A 0.2Ω coil being operated at around 55W will generally consume more e-liquid than a higher-resistance coil operating around 10W–15W. 

The exact amount will still depend on puff duration, frequency and airflow. 

Does Wattage Affect How Much Vape Juice You Use? 

Generally, yes. 

Higher wattage means the coil is producing more heat, which can produce more vapour and increase e-liquid consumption. 

For example, an MTL coil operating at around 10W–12W has a very different consumption profile from a low-resistance mesh coil operating at 55W–70W. 

If you're regularly increasing your wattage, you may notice that your e-liquid bottle empties faster. 

Always use your coil within the manufacturer's recommended wattage range. 

How Much E-Liquid Do Nicotine Salt Users Need? 

Nicotine salts are commonly used with lower-powered pod devices because they can provide higher nicotine strengths without requiring the large vapour production associated with sub-ohm vaping. 

Tidal Vape stocks a range of 10ml nic salt e-liquids, including brands such as: 

If you use approximately 2ml per day, your consumption would be: 

In this situation, several 10ml bottles can be a practical option. 

How Long Does 50ml Vape Juice Last? 

The easiest calculation is: 

50ml ÷ daily consumption = approximate number of days 

For example: 

Therefore, a vaper consuming around 5ml per day would use approximately 35ml per week, making a 50ml bottle roughly a 10-day supply. 

How Long Does 100ml Vape Juice Last? 

The same calculation applies to a 100ml supply. 

At: 

For heavier sub-ohm users, 100ml shortfills can therefore be more practical than repeatedly buying smaller bottles. 

For a lighter pod user consuming only 1ml–2ml per day, however, buying 100ml at once may be unnecessary. 

How Much Vape Juice Do You Need Per Month? 

Once you know your weekly consumption, estimating your monthly requirement is simple. 

These are approximate figures based on four to four-and-a-third weeks per month. 

For example, someone using around 20ml per week could expect to use approximately 80–90ml per month. 

What About Sub-Ohm Vaping? 

Sub-ohm vaping generally consumes more e-liquid because low-resistance coils operate at higher wattages and produce considerably more vapour. 

For example, the Geekvape Zeus Z1 Mesh Coil operates at around 60W–70W and is designed for high-VG e-liquid containing 60% VG or more. 

This is very different from an MTL setup using a 1.8Ω coil at around 10W–12W. 

If you're using a powerful sub-ohm device such as the Geekvape Aegis Legend III, a weekly consumption of 30ml or more can be possible for heavier users. 

For these setups, 50ml and 100ml shortfills may be more practical. 

Does Puff Length Affect E-Liquid Consumption? 

Absolutely. 

Two people can use exactly the same vape kit and consume very different amounts of e-liquid. 

Consider these two examples: 

Vaper A 

Vaper B 

Vaper B is likely to consume substantially more e-liquid because they're using higher power, a lower-resistance coil, longer draws and significantly more puffs. 

This is why puff counts alone aren't a reliable way to calculate refillable e-liquid consumption. 

Why Am I Going Through Vape Juice So Quickly? 

If your bottle seems to disappear unusually quickly, several factors could be responsible. 

You may be: 

Chain vaping can be particularly noticeable with powerful mesh coils because these setups can vaporise considerably more e-liquid with each draw. 

If your consumption has suddenly increased, check your wattage, coil resistance and vaping frequency. 

How Do You Calculate Your Actual Weekly Usage? 

You don't need to rely on estimates forever. 

The most accurate method is to measure your own consumption over seven days. 

Step 1: Start with a known quantity 

For example, begin with 20ml of e-liquid. 

Step 2: Vape normally for seven days 

Don't deliberately increase or decrease your usual vaping. 

Step 3: Measure what remains 

At the end of the week, check how much e-liquid is left. 

Step 4: Calculate your consumption 

If you started with 20ml and finished with 5ml: 

20ml − 5ml = 15ml used 

Your weekly consumption is therefore approximately 15ml. 

This is more useful than comparing yourself with an "average" vaper because it reflects your actual device and vaping habits. 

Millilitres Matter More Than Puff Counts 

Puff counts can be useful when comparing certain prefilled devices, but they aren't a reliable measurement of refillable e-liquid consumption. 

Your puff count can vary according to: 

Someone taking short MTL draws may get significantly more puffs from 2ml than someone taking long DTL draws at 60W. 

For refillable vape kits, millilitres per day or week are a much more useful measurement. 

Which Vape Setup Uses the Least E-Liquid? 

If your priority is reducing e-liquid consumption, a higher-resistance, lower-powered MTL setup is generally a more economical choice. 

For example: 

Aspire Nautilus 3 + 1.8Ω Nautilus BVC coil + suitable 50/50 e-liquid 

has a very different consumption profile from: 

Geekvape Aegis Legend III + Zeus tank + 0.4Ω mesh coil + suitable high-VG e-liquid 

The first setup is designed around lower power and a tighter draw, while the second is designed to produce substantially more vapour. 

Neither approach is inherently better. They are simply designed for different vaping styles and have different e-liquid requirements. 

How Much Vape Juice Should You Buy for a Week? 

Your device and typical consumption provide the best starting point. 

Lower-powered MTL setup 

You may need approximately 5ml–15ml per week, depending on how frequently you vape. 

10ml bottles can be a convenient choice for this type of setup. 

Pod setup 

A moderate pod user may consume approximately 10ml–20ml per week. 

Several 10ml bottles can provide flexibility when using nicotine salts or other pod-compatible e-liquids. 

RDTL setup 

A regular RDTL user may consume approximately 20ml–30ml per week, depending on coil resistance and wattage. 

Sub-ohm setup 

A heavier sub-ohm user may consume 30ml–50ml or more per week. 

50ml and 100ml shortfills can be more practical for higher-consumption setups. 

Always choose an e-liquid that is appropriate for your specific coil and device. 

So, How Much Vape Juice Do You Need Per Week? 

For many adult vapers, 10ml–30ml per week is a useful starting range, but your actual requirement depends on your setup and vaping habits. 

As a rough guide: 

The most important factors are your vape kit, coil resistance, wattage, puff length and vaping frequency. 

The easiest way to find your own requirement is to measure how many millilitres you use over seven days. Once you know that figure, choosing the right amount of e-liquid becomes much easier. 

Whether you're using 10ml nic salts with a compact pod or 50ml/100ml shortfills with a powerful sub-ohm setup, the right amount is ultimately the amount that matches your device and your vaping habits.
