Vaping enthusiasts often enjoy creating their own e-liquids for a personalized experience. A DIY E-Juice Calculator helps hobbyists and professionals accurately mix Propylene Glycol (PG), Vegetable Glycerin (VG), nicotine, and flavorings to create the perfect vape juice. Using a calculator reduces errors, ensures safety, and allows precise control over nicotine strength, flavor intensity, and liquid consistency.

What Is a DIY E-Juice Calculator?

A DIY E-Juice Calculator is an online tool used to:

• Determine the exact amounts of PG, VG, nicotine, and flavoring
• Calculate nicotine strength in milligrams per milliliter (mg/mL)
• Adjust VG/PG ratios for preferred throat hit and vapor production
• Reduce mistakes in manual measurements
• Plan large or small batch mixes efficiently

It is essential for anyone interested in crafting e-liquids safely and consistently.

How the DIY E-Juice Calculator Works

The calculator uses your desired final e-liquid volume, nicotine strength, flavor percentage, and PG/VG ratio to compute the exact amounts of each ingredient.

Typical inputs:

• Desired batch size (in milliliters)
• Target nicotine strength (mg/mL)
• Nicotine base concentration (mg/mL)
• Flavoring percentage (%)
• PG/VG ratio (e.g., 50/50, 70/30)

Outputs include the volume of:

• Nicotine base (PG or VG-based)
• Flavoring concentrate
• PG and VG to reach the desired ratio and final volume

Plain Text Formulas

1. Nicotine Amount:

Nicotine (ml) = (Target Nicotine Strength × Total Volume) ÷ Nicotine Base Strength 

2. Flavoring Amount:

Flavor (ml) = Total Volume × (Flavor Percentage ÷ 100) 

3. PG and VG Amounts:

PG (ml) = (Total Volume − Nicotine − Flavor) × (PG Ratio ÷ 100) VG (ml) = (Total Volume − Nicotine − Flavor) × (VG Ratio ÷ 100) 

4. Verification:

Total Volume = Nicotine + Flavor + PG + VG 

These formulas ensure your e-juice is mixed precisely according to your preferences.

How to Use the DIY E-Juice Calculator

Step 1: Enter Desired Volume

Specify the total e-liquid volume you want to make (e.g., 100 mL).

Step 2: Set Target Nicotine Strength

Choose your preferred nicotine strength in mg/mL.

Step 3: Enter Nicotine Base Concentration

Input the concentration of your nicotine base (e.g., 100 mg/mL).

Step 4: Set Flavor Percentage

Determine the percentage of flavoring (usually 5–20%).

Step 5: Select PG/VG Ratio

Adjust PG and VG percentages for throat hit and vapor production.

Step 6: Click Calculate

The calculator provides precise measurements for:

• Nicotine base
• PG
• VG
• Flavoring

Step 7: Mix Ingredients Safely

Use a clean workspace, gloves, and accurate measuring tools to mix your DIY e-juice.

Example Calculations

Example 1: Basic 50/50 Mix

• Total Volume: 100 mL
• Target Nicotine: 6 mg/mL
• Nicotine Base: 100 mg/mL
• Flavoring: 10%
• PG/VG Ratio: 50/50

Step 1: Nicotine Volume:

Nicotine = (6 × 100) ÷ 100 = 6 mL 

Step 2: Flavor Volume:

Flavor = 100 × (10 ÷ 100) = 10 mL 

Step 3: Remaining Base Volume:

Base = 100 − 6 − 10 = 84 mL 

Step 4: PG and VG Split:

PG = 84 × 0.5 = 42 mL VG = 84 × 0.5 = 42 mL 

Result:

• Nicotine: 6 mL
• Flavor: 10 mL
• PG: 42 mL
• VG: 42 mL

Example 2: High VG Mix for Cloud Chasing

• Total Volume: 60 mL
• Target Nicotine: 3 mg/mL
• Nicotine Base: 100 mg/mL
• Flavoring: 15%
• PG/VG Ratio: 30/70

Step 1: Nicotine Volume:

Nicotine = (3 × 60) ÷ 100 = 1.8 mL 

Step 2: Flavor Volume:

Flavor = 60 × 0.15 = 9 mL 

Step 3: Remaining Base Volume:

Base = 60 − 1.8 − 9 = 49.2 mL 

Step 4: PG/VG Split:

PG = 49.2 × 0.3 ≈ 14.76 mL VG = 49.2 × 0.7 ≈ 34.44 mL 

Result:

• Nicotine: 1.8 mL
• Flavor: 9 mL
• PG: 14.76 mL
• VG: 34.44 mL
