Frequently Asked Questions

How does the e liquid calculator help with DIY vape juice?

It lets you input your target nicotine strength, bottle size, and PG/VG ratio to get exact amounts of each ingredient. It calculates how much nicotine shot, VG, PG, and flavouring you need. It provides the precise measurements for your vape recipe, tailored to your target strength, ratio, and bottle size.

Who uses a vape juice calculator?

This tool is used by UK vapers who mix at home, from casual users topping up shortfills to hobbyists creating full custom blends. It’s ideal for anyone using nic shots or experimenting with flavour concentrates. A tool like this also helps ex-smokers control their nicotine levels as they taper down or adjust over time.

What’s the purpose of a nicotine shot calculator?

It tells you how many millilitres of an 18mg nic shot to add to a shortfill to reach your desired strength. For example, to turn a 50ml shortfill into a 3mg e-liquid, you’d typically add one 10ml nic shot. This nic shot calculator automates the process and ensures the result is accurate every time.

Can the ejuice calculator adjust PG/VG ratios?

Yes. This mixing ratio calculator allows you to set your own PG/VG blend, whether you prefer a 70/30 ratio for smoothness or 50/50 for a stronger throat hit. It accounts for the VG or PG content in your nicotine base and flavourings, so your final mix matches your chosen ratio as closely as possible.

Is this tool compatible with shortfills?

Absolutely. It doubles as a shortfill calculator, designed specifically for UK vapers who buy nicotine-free e-liquid and add nic shots later. Just enter the shortfill size, target strength, and nicotine base details. The eliquid calc handles the rest, giving you exact measurements for your mix.

What’s the difference between a nic shot calculator and an e liquid calculator?

A nic shot calculator focuses on how much Nic Shot you need for a target strength. An eliquid calculator covers the whole recipe, including flavouring and PG/VG base. Ours does both. Whether you're using a premixed shortfill or building your own blend from scratch, it works as a complete DIY e-liquid tool.
