DIY vaping has become increasingly popular, giving enthusiasts full control over nicotine strength, flavor, and liquid consistency. The E-Juice Calculator is an essential tool that ensures accurate measurement of ingredients like Propylene Glycol (PG), Vegetable Glycerin (VG), nicotine, and flavor concentrates.

What Is an E-Juice Calculator?

An E-Juice Calculator is a tool that:

• Determines exact volumes of PG, VG, nicotine, and flavoring
• Calculates the target nicotine strength in mg/mL
• Adjusts VG/PG ratios for throat hit and vapor production
• Prevents mistakes in manual mixing
• Supports consistent and safe DIY e-liquid creation

It is ideal for both hobbyists and professionals wanting precise control over their vaping liquids.

How the E-Juice Calculator Works

The calculator uses several inputs to determine the required amounts of each component:

1. Desired e-liquid volume (mL)
2. Target nicotine strength (mg/mL)
3. Nicotine base concentration (mg/mL)
4. Flavoring percentage (%)
5. PG/VG ratio (e.g., 50/50, 30/70)

The calculator then computes:

• Nicotine base volume
• Flavor concentrate volume
• PG and VG amounts to reach the desired ratio
• Total liquid confirmation

Plain Text Formulas

1. Nicotine Volume:

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

2. Flavoring Volume:

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

3. PG and VG Volumes:

Remaining Base = Total Volume − Nicotine − Flavor PG (mL) = Remaining Base × (PG Ratio ÷ 100) VG (mL) = Remaining Base × (VG Ratio ÷ 100) 

4. Total Check:

Total Volume = Nicotine + Flavor + PG + VG 

These formulas guarantee precise measurements for safe and consistent e-liquid mixing.

How to Use the E-Juice Calculator

Step 1: Enter Total Volume

Input the final batch size of your e-liquid (e.g., 100 mL).

Step 2: Set Nicotine Strength

Choose your desired nicotine level in mg/mL.

Step 3: Enter Nicotine Base Strength

Provide the concentration of your nicotine base solution.

Step 4: Enter Flavor Percentage

Specify the percentage of flavoring (commonly 5–20%).

Step 5: Select PG/VG Ratio

Choose the desired ratio for vapor density and throat hit.

Step 6: Click Calculate

The calculator outputs exact measurements for:

• Nicotine base
• PG
• VG
• Flavoring

Step 7: Mix Safely

Use gloves, syringes, and clean containers to mix your e-juice accurately.

Example Calculations

Example 1: 50/50 Mix

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

Nicotine Volume:

(6 × 100) ÷ 100 = 6 mL 

Flavor Volume:

100 × 0.10 = 10 mL 

Remaining Base:

100 − 6 − 10 = 84 mL 

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

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

Nicotine Volume:

(3 × 60) ÷ 100 = 1.8 mL 

Flavor Volume:

60 × 0.15 = 9 mL 

Remaining Base:

60 − 1.8 − 9 = 49.2 mL 

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
