Nicotine Shot Calculator
for Shortfill E Liquid
How Many Nicotine Shots Do I Need?
If you’re wondering, “How many nic shots do I need to add to my shortfill e-liquid to get my desired nicotine strength?”, our handy Nicotine Shot Calculator is here to help. Whether you’re new to vaping or stepping up your vape game, this tool makes it easy to get the right nicotine strength every time.
What is a Nicotine Shot?

Nicotine shots are small bottles of concentrated nicotine liquid, usually available in strengths like 11mg, 18mg, or 20mg. They’re designed to be added to nicotine-free shortfill e-liquids to give you control over your final nicotine level.
Shortfill bottles typically come in 50ml or 100ml sizes and are not completely full — leaving space for you to add nic shots safely without diluting flavour or quality.
How to Use the Nicotine Shot Calculator

1. Select your shortfill bottle size (e.g., 50ml or 100ml).

2. Choose the strength of the nic shot you plan to add (e.g., 18mg).

3. Enter the desired nicotine strength you want in your finished e-liquid (e.g., 3mg).

4. The calculator tells you exactly how many nic shots to add for the perfect vape experience.

Nic Shots Added Approximate Nicotine Strength (mg) for 100ml Shortfill

2 - Low (around 3mg)
4 to 5 - Medium (around 6mg)
Why Is Getting the Right Nicotine Strength Important?
Choosing the correct nicotine strength is crucial for satisfying your cravings and avoiding common issues like nicotine overdose (dizziness, nausea) or withdrawal symptoms (irritability, headaches).
This is especially important if you’re switching from smoking cigarettes to vaping, where the nicotine delivery method differs and needs adjustment.
Shortfill E-liquids and Nic Shots: A Perfect Pair

Shortfill e-liquids are nicotine-free and come in larger bottles. You add your own nic shots to get your desired strength, making them a flexible and popular choice for vapers who want to customise their experience.
