PG/VG E-Liquid Calculator
Enter your target mix settings below. This calculator estimates how much nicotine base, flavoring, extra PG, and extra VG to add.
What is a PG VG calculator?
A PG VG calculator helps DIY e-liquid mixers calculate the exact amount of each ingredient needed for a target recipe. Instead of doing everything by hand, you can set your desired bottle size, nicotine strength, flavor percentage, and final PG/VG ratio, then get a clear breakdown in milliliters.
If you have ever asked, “How much PG and VG do I add for a 60 ml bottle at 70/30?” this tool is built for that exact question.
PG vs VG: quick refresher
Propylene Glycol (PG)
- Thinner liquid consistency
- Stronger throat hit
- Carries flavor very well
- Commonly used in nicotine bases and flavor concentrates
Vegetable Glycerin (VG)
- Thicker, more viscous liquid
- Smoother inhale for many users
- Produces denser vapor clouds
- Can slightly mute flavor at very high percentages
How to use this pg vg calculator
1) Choose total batch size
Set the final volume you want to make, such as 30 ml, 60 ml, or 120 ml.
2) Set your target ratio
Enter target PG and VG percentages. Most people use combinations like 50/50, 30/70, or 20/80.
3) Enter nicotine settings
Add your desired nicotine strength and your nicotine base strength. Then specify whether your nicotine base is PG-heavy, VG-heavy, or a blend.
4) Add flavor information
Input your total flavor percentage and the carrier split of those flavors. Many flavor concentrates are effectively PG-based, so a common value is 100% PG and 0% VG.
5) Click calculate
The tool returns how much nicotine base, flavoring, extra PG, and extra VG to add to hit your target.
The core calculation logic
At a high level, the calculator solves these steps:
Nicotine ml = (Target mg/ml × Total ml) / Nic Base mg/mlFlavor ml = Total ml × (Flavor % / 100)- Convert nicotine and flavor contributions into PG and VG portions using their carrier percentages
- Subtract those contributions from desired PG and VG totals
If the resulting extra PG or extra VG is negative, your requested setup is not physically possible with the selected base and flavor assumptions. In that case, lower flavor percentage, change nicotine carrier, or adjust target ratio.
Example scenario
Suppose you want:
- 60 ml total
- 30% PG / 70% VG
- 3 mg/ml nicotine
- 100 mg/ml nicotine in PG
- 10% flavoring (PG-based)
The calculator will show the nicotine and flavor portions first, then top off with extra PG/VG to reach your exact 60 ml target and final ratio.
Common mixing mistakes this tool helps avoid
- Forgetting that nicotine base changes PG/VG balance
- Ignoring the PG content of flavor concentrates
- Using percentages that do not sum cleanly
- Accidentally overshooting the bottle size
Safety notes for DIY mixing
- Wear gloves when handling nicotine concentrates
- Label every bottle with strength, date, and ratio
- Keep ingredients away from children and pets
- Use accurate syringes or a calibrated scale
- Clean tools and workspace immediately after mixing
FAQ
Can I use this for zero-nicotine recipes?
Yes. Set target nicotine to 0 and nicotine base strength can be left as-is.
What if my PG and VG targets do not add to 100?
The calculator normalizes the values proportionally and displays a note in the result panel.
Do all flavors use PG?
No. Many do, but not all. If your flavor system includes VG-based concentrates, update the flavor carrier fields accordingly.
Final thoughts
A reliable PG VG calculator saves time, reduces waste, and makes your mixing process repeatable. Start with small test batches, keep notes on every recipe, and adjust gradually. Precision is what turns random experiments into consistently good results.
