The E-Juice Calculator is an essential tool for DIY vapers, providing the exact volumes of Nicotine Base, Flavoring, and Diluent (PG/VG) required to achieve a desired nicotine strength and total batch size. Never guess your mix again!
E-Juice Mixing Calculator
E-Juice Mixing Formula
The calculation relies on the principle of dilution to determine the volume of concentrated nicotine required to reach the target strength.
$$V_{\text{nic}} = \frac{N_{\text{target}} \times V_{\text{total}}}{N_{\text{base}}}$$
Flavoring Volume (V_flav) = (Flavoring Percentage / 100) $\times$ Total Batch Volume
Remaining PG/VG Base Volume (V_base) = $V_{\text{total}} – V_{\text{nic}} – V_{\text{flav}}$

Variables
Understanding the inputs ensures you mix your e-juice accurately:
- Target Nicotine Strength ($\mathbf{N_{\text{target}}}$): The final nicotine level (in mg/mL) you wish the e-juice to have.
- Nicotine Base Strength ($\mathbf{N_{\text{base}}}$): The strength (in mg/mL) of the nicotine concentrate you are using (e.g., 100mg/mL).
- Total Batch Volume ($\mathbf{V_{\text{total}}}$): The total amount of e-juice (in mL) you plan to make.
- Flavoring Percentage ($\mathbf{P_{\text{flav}}}$): The percentage of the total volume that will be dedicated to flavor concentrates, recommended by the flavor manufacturer.

What is an E-Juice Calculator?
An E-Juice (or E-Liquid) calculator is a specialized tool that automates the complex mathematical process of mixing custom vape liquids. Because vapers use highly concentrated nicotine bases (often 100mg/mL or higher) and various flavor concentrates, precise measurement is crucial for safety and flavor accuracy. This calculator eliminates the risk of human error in dilution.
The core function of the calculator is to determine the exact volume of each component—nicotine, flavoring, and the diluent base (Propylene Glycol (PG) and Vegetable Glycerin (VG))—needed to fill the target bottle volume while maintaining the desired final nicotine concentration. This ensures that the final product is safe to use and tastes as intended.
How to Calculate an E-Juice Recipe (Example)
Let’s calculate a 30mL batch with 6mg/mL nicotine using a 100mg/mL base and 12% flavoring:
- Calculate Nicotine Volume: $V_{\text{nic}} = (6 \text{ mg/mL} \times 30 \text{ mL}) / 100 \text{ mg/mL} = 1.8 \text{ mL}$.
- Calculate Flavoring Volume: $V_{\text{flav}} = (12\% / 100) \times 30 \text{ mL} = 3.6 \text{ mL}$.
- Calculate Base Volume: $V_{\text{base}} = 30 \text{ mL} – 1.8 \text{ mL} – 3.6 \text{ mL} = 24.6 \text{ mL}$.
- Conclusion: To create this recipe, you need 1.8mL Nicotine Base, 3.6mL Flavoring, and 24.6mL of your unflavored PG/VG mix.
Frequently Asked Questions (FAQ)
Here are common questions about mixing e-liquid:
Is DIY e-juice mixing safe?
Mixing e-juice can be safe, but only if you handle concentrated nicotine (especially 100mg/mL+) with extreme caution, wearing gloves and eye protection in a well-ventilated area. Always use precise measurements from a reliable calculator like this one.
What is the purpose of PG and VG?
Propylene Glycol (PG) and Vegetable Glycerin (VG) are the primary diluents. PG carries flavor and provides a throat hit, while VG produces the majority of the vapor clouds.
Why is the Nicotine Base Strength always higher than the Target Strength?
The Nicotine Base is a highly concentrated liquid. You must dilute it with flavoring and PG/VG base to achieve a lower, safe, and pleasant-to-vape target concentration.
What happens if my required base volume is negative?
A negative base volume means the combined volume of your Nicotine Base and Flavoring is greater than your total batch size. This is impossible. You must lower your Nicotine Base Strength, Target Nicotine Strength, or Flavoring Percentage to fix this error.
