- Flavor Chasers: Experimenting with different flavor combinations and percentages is easy with a calculator to guide the ratios.
Common Misconceptions:
- It’s overly complicated: While mixing has variables, the calculator automates the math, making it accessible.
- You need professional equipment: Basic tools like syringes, beakers, and bottles are usually sufficient for home mixing.
- All e-liquids are the same: The calculator highlights how differences in PG/VG, nicotine, and flavors create vastly different vaping experiences.
E-Liquid Calculator Formula and Mathematical Explanation
The core of the e-liquid calculator involves calculating the required volume of each component based on the user’s input. The calculations are primarily based on percentages and desired final volumes.
Step-by-Step Calculation Breakdown:
- Calculate Non-Flavor Base Volume: The total volume minus the volume dedicated to flavors.
- Calculate Required Nicotine Volume: Determine how much of the nicotine base is needed to achieve the target nicotine strength in the total volume.
- Calculate PG and VG Volumes: Based on the non-flavor base volume and the desired PG/VG ratio, calculate the precise amounts of PG and VG needed.
Variables and Formulas:
Let’s define the variables used in the calculator:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| TV (Total Volume) | Desired final volume of the e-liquid. | ml | 10 – 500+ |
| TNS (Target Nicotine Strength) | Desired final nicotine concentration. | mg/ml | 0 – 50+ |
| NBS (Nicotine Base Strength) | Concentration of the nicotine liquid used. | mg/ml | 10 – 1000+ (Use extreme caution with high concentrations) |
| PGVG% (Target PG/VG Ratio) | Desired percentage of PG in the final liquid (VG% = 100 – PG%). | % | 0 – 100 |
| FP% (Total Flavoring Percentage) | Total percentage of all flavor concentrates. | % | 1 – 25+ |
| FV (Flavor Volume) | Calculated volume of flavor concentrates. | ml | Calculated |
| NFV (Non-Flavor Base Volume) | Volume for Nicotine, PG, and VG. | ml | Calculated |
| NV (Nicotine Volume) | Calculated volume of nicotine base liquid needed. | ml | Calculated |
| PGV (PG Volume) | Calculated volume of PG needed. | ml | Calculated |
| VGV (VG Volume) | Calculated volume of VG needed. | ml | Calculated |
Core Calculation Logic:
1. Flavor Volume (FV):
FV = TV * (FP% / 100)
This determines the total volume dedicated solely to flavorings.
2. Non-Flavor Base Volume (NFV):
NFV = TV - FV
This is the remaining volume available for nicotine, PG, and VG.
3. Nicotine Volume (NV):
NV = (TNS * TV) / NBS
This formula calculates the exact amount of the higher-concentration nicotine base required to achieve the target TNS in the total volume TV.
Important Note: The nicotine base volume (NV) must be less than or equal to the Non-Flavor Base Volume (NFV). If NV > NFV, it means you’re trying to achieve a nicotine strength that requires more pure nicotine than your total recipe allows after accounting for flavors. In such cases, the target nicotine strength might be too high for the specified total volume and flavor percentage.
4. PG and VG Volumes (PGV, VGV):
First, determine the volume available for PG and VG after accounting for nicotine:
PG_VG_Base_Volume = NFV - NV
Then, calculate the individual volumes based on the desired PG/VG ratio:
PGV = PG_VG_Base_Volume * (PGVG% / 100)
VGV = PG_VG_Base_Volume * ((100 - PGVG%) / 100)
These formulas distribute the remaining base volume between PG and VG according to the user’s preference.
Practical Examples (Real-World Use Cases)
Example 1: Standard Cloud Chasing Blend
A user wants to make 120ml of e-liquid with a moderate nicotine level and a balanced PG/VG ratio suitable for sub-ohm vaping.
- Inputs:
- Total Volume: 120 ml
- Target Nicotine Strength: 3 mg/ml
- Nicotine Base Strength: 100 mg/ml
- Target PG/VG Ratio: 30% PG / 70% VG
- Total Flavoring Percentage: 15%
Calculated Results:
- Main Result (Total Volume): 120 ml
- Nicotine Base Volume: (3 * 120) / 100 = 3.6 ml
- Flavor Volume: 120 * (15 / 100) = 18 ml
- Non-Flavor Base Volume: 120 – 18 = 102 ml
- PG/VG Base Volume (after nicotine): 102 – 3.6 = 98.4 ml
- PG Volume: 98.4 * (30 / 100) = 29.52 ml
- VG Volume: 98.4 * (70 / 100) = 68.88 ml
Interpretation: To achieve this 120ml blend, the user needs to mix 3.6ml of 100mg/ml nicotine base, 18ml of flavor concentrates, 29.52ml of PG, and 68.88ml of VG. The resulting liquid will have 3mg/ml nicotine and a 30/70 PG/VG ratio.
Example 2: Nicotine-Free Mouth-to-Lung (MTL) Blend
A user wants to create 30ml of a flavor-focused, nicotine-free e-liquid with a higher PG concentration for a tight draw (MTL) setup.
- Inputs:
- Total Volume: 30 ml
- Target Nicotine Strength: 0 mg/ml
- Nicotine Base Strength: 100 mg/ml (though not used)
- Target PG/VG Ratio: 70% PG / 30% VG
- Total Flavoring Percentage: 12%
Calculated Results:
- Main Result (Total Volume): 30 ml
- Nicotine Base Volume: (0 * 30) / 100 = 0 ml
- Flavor Volume: 30 * (12 / 100) = 3.6 ml
- Non-Flavor Base Volume: 30 – 3.6 = 26.4 ml
- PG/VG Base Volume (after nicotine): 26.4 – 0 = 26.4 ml
- PG Volume: 26.4 * (70 / 100) = 18.48 ml
- VG Volume: 26.4 * (30 / 100) = 7.92 ml
Interpretation: For this 30ml batch, the user requires 0ml of nicotine base, 3.6ml of flavorings, 18.48ml of PG, and 7.92ml of VG. This recipe is nicotine-free and optimized for MTL devices due to its higher PG content.
How to Use This E-Liquid Calculator
Using the DIY E-Liquid Mixer calculator is straightforward. Follow these steps to get your precise recipe:
Step-by-Step Instructions:
- Determine Your Desired Recipe: Decide on the total volume (e.g., 60ml, 100ml), the nicotine strength (mg/ml) you want in the final liquid, and the PG/VG ratio (e.g., 50/50, 70/30).
- Know Your Nicotine Base: Check the concentration (mg/ml) of the nicotine liquid you have available. This is crucial for accurate calculations. Handle nicotine base with care and use appropriate safety gear.
- Select Flavor Percentage: Estimate the total percentage of flavor concentrates you wish to use. This can vary widely depending on the flavors, but 5-15% is a common starting point.
- Input Values: Enter your desired Total Volume, Target Nicotine Strength, Nicotine Base Strength, Target PG/VG Ratio (enter the PG percentage), and Total Flavoring Percentage into the respective fields.
- Click Calculate: Press the “Calculate Ingredients” button.
How to Read Results:
- Main Result: This displays the total volume of e-liquid you will be creating, matching your input.
- Nicotine Base: The volume (in ml) of your high-concentration nicotine liquid to add.
- PG Volume: The volume (in ml) of Propylene Glycol to add.
- VG Volume: The volume (in ml) of Vegetable Glycerin to add.

The calculator provides the exact measurements needed. Remember that accuracy in measuring, especially for nicotine, is paramount for safety and achieving your desired result. Using precision scales (measuring by weight) is often recommended for advanced DIY mixing, but volumetric measurements (ml) are common for beginners.
Decision-Making Guidance:
Use the results to guide your mixing process:
- Nicotine Level: Adjust the “Target Nicotine Strength” to match your preference or tapering goals.
- Throat Hit & Vapor Production: Higher PG generally means more throat hit and faster wicking (good for MTL devices), while higher VG means denser vapor and a smoother hit (good for sub-ohm, cloud chasing).
- Flavor Intensity: Adjust “Total Flavoring Percentage” to achieve the desired flavor strength. Higher percentages can sometimes mute flavors or require longer steeping.
Key Factors That Affect E-Liquid Results
Several factors influence the final outcome of your DIY e-liquid beyond the basic calculator inputs. Understanding these helps in fine-tuning your recipes:
- Nicotine Base Strength & Purity: The accuracy of your “Nicotine Base Strength” input is critical. Ensure you are using the stated concentration. The purity and source of your nicotine also matter for safety and taste. Always handle concentrated nicotine with extreme caution.
- PG/VG Ratio Accuracy: While the calculator calculates based on percentages, the actual PG and VG liquids you use might have slight impurities or different densities. For highly sensitive builds, slight adjustments might be needed.
- Flavor Concentrate Percentages: Different flavorings have varying potencies. A 10% mix of one brand’s strawberry might be different from another’s. It’s essential to consult flavor-specific recommendations and adjust the “Total Flavoring Percentage” accordingly.
- Steeping Time: Many complex e-liquids benefit from “steeping”—allowing the mixture to sit for a period (days to weeks). This allows the flavors to meld and mature, significantly changing the taste profile. The calculator doesn’t account for steeping, but it’s a vital part of the DIY process.
- Temperature and Storage: Storing your e-liquid correctly impacts its shelf life and flavor integrity. Extreme temperatures or prolonged exposure to light can degrade nicotine and alter flavor.
- Mixing Accuracy (Measurement): The precision with which you measure each component directly impacts the final result. Small errors in measuring nicotine base, especially, can lead to significantly higher or lower nicotine content than intended. Using scales for weight-based mixing can improve accuracy.
- Device Compatibility: The PG/VG ratio significantly affects how well an e-liquid performs with different vaping devices. High PG is better for Mouth-to-Lung (MTL) devices with smaller coils, while high VG is preferred for Direct-to-Lung (DTL) or sub-ohm devices with larger airflow and coils.
- Ingredient Quality: The quality of the base ingredients (PG, VG, Nicotine) and the flavorings used directly impacts the final taste and vapor quality. Using pharmaceutical-grade ingredients is recommended.
Frequently Asked Questions (FAQ)
Q1: How accurate are e-liquid calculators?
E-liquid calculators are highly accurate for the mathematical aspect of mixing. They provide precise volumetric measurements based on your inputs. However, the final taste and experience also depend on the quality of ingredients, flavor potencies, and steeping, which are external factors.
Q2: Is it safe to mix my own e-liquid?
It can be safe if proper precautions are taken, especially when handling concentrated nicotine. Always wear gloves and eye protection, work in a well-ventilated area, keep ingredients away from children and pets, and use the calculator to ensure accurate (and safe) nicotine levels.
Q3: What does PG/VG ratio mean, and why is it important?
PG (Propylene Glycol) provides throat hit and flavor intensity, while VG (Vegetable Glycerin) produces larger vapor clouds and a smoother vape. The ratio determines the balance between these effects. For example, 50/50 is balanced, while 70/30 PG/VG offers more throat hit, and 30/70 PG/VG offers more vapor.
Q4: Can I mix multiple flavors using this calculator?
Yes. The “Flavor Volume” output is the *total* volume for all flavor concentrates. You’ll need to break this down further yourself based on the individual percentages required for each flavor to reach that total. For instance, if the calculator says 5ml total flavor, you might use 3ml of one flavor and 2ml of another.
Q5: What is “steeping,” and do I need to do it?
Steeping is the process of letting your mixed e-liquid mature over time. It allows the chemical reactions between ingredients (especially flavorings) to occur, resulting in a more blended and often richer flavor profile. Many complex recipes benefit significantly from steeping, while simple fruit flavors might be fine immediately.
Q6: My calculated nicotine base volume is very small. How do I measure it accurately?
Measuring small volumes like 0.5ml or less can be challenging with basic tools. Using small, precise syringes (e.g., 1ml or 3ml) is recommended. For extremely small amounts or higher precision, consider using a milligram scale to measure by weight, converting ml to grams using the density of your nicotine base.
Q7: What happens if my Nicotine Base Strength is not 100mg/ml?
The calculator accounts for this! Just input your actual Nicotine Base Strength (e.g., 36mg/ml, 50mg/ml, 200mg/ml) into the “Nicotine Base Strength” field. The calculator will adjust the required “Nicotine Base Volume” accordingly.
Q8: Can I use this calculator for salts (nicotine salts)?
Yes, this calculator works for both freebase nicotine and nicotine salts, provided you input the correct strength (mg/ml) for your nicotine salt base. Nicotine salts often allow for higher concentrations with less throat harshness compared to freebase nicotine.
Q9: What if the calculated Nicotine Base Volume is higher than the Total Volume or NFV?
This indicates an impossible recipe scenario. It typically means the Target Nicotine Strength is too high for the given Total Volume and Nicotine Base Strength, or the Flavor Percentage is too low, leaving insufficient room for the nicotine base. You’ll need to lower the Target Nicotine Strength or increase the Total Volume.
