Mix it right, every time.

It lets you set your target nicotine strength, bottle size, and PG/VG ratio, then gives you the exact amounts of each ingredient. The calculator works out how much nicotine shot, VG, PG, and flavouring you need — precise measurements tailored to your target strength, ratio, and bottle size.

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. It also helps ex-smokers control their nicotine levels as they taper down over time.

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. The calculator automates the maths and ensures the result is accurate every time.

Yes. You can set your own PG/VG blend — 70/30 for smoothness, 50/50 for a stronger throat hit, or anywhere in between. The calculator accounts for the PG or VG content already in your nicotine base, so your final mix matches your chosen ratio as closely as possible.

Absolutely. It works as a shortfill calculator designed for UK vapers who buy nicotine-free e-liquid and add nic shots later. Enter the shortfill size, target strength, and nicotine base details — and the calculator handles the rest.

A nic shot calculator focuses on how much nic shot you need for a target strength. An e-liquid calculator covers the whole recipe, including flavouring and PG/VG base. This one does both — whether you're using a premixed shortfill or building your own blend from scratch.
