If you are a homebrewer or professional brewer, understanding the alcohol content of your beer is essential. The ABV Gravity Calculator is designed to simplify this process by calculating the Alcohol by Volume (ABV) using the Original Gravity (OG) and Final Gravity (FG) of your brew.
🍺 ABV Gravity Calculator
Please enter valid OG and FG values (OG > FG).
Result
ABV is a key metric that tells you how much alcohol is present in your beverage. Traditional calculation methods require a formula and manual input, which can be time-consuming and prone to error. This calculator removes the guesswork, giving you instant, accurate results to ensure your brews are consistent and properly measured.
Whether you are crafting a light lager or a strong stout, this tool ensures your brewing process is precise, reliable, and efficient.
How the ABV Gravity Calculator Works
The calculator works based on a simple formula used in brewing:
ABV (%) = (OG – FG) × 131.25
- Original Gravity (OG): Measures the density of the wort before fermentation.
- Final Gravity (FG): Measures the density of the beer after fermentation.
By entering these two values, the calculator instantly determines the ABV, providing results in percentage form.
Step-by-Step Instructions to Use the ABV Gravity Calculator
Follow these simple steps to get accurate ABV results:
Step 1: Enter Original Gravity (OG)
Input the original gravity of your brew, typically ranging from 1.030 to 1.120 depending on your recipe. For example: 1.050.
Step 2: Enter Final Gravity (FG)
Input the final gravity after fermentation. This is usually lower than OG, for example: 1.010.
Step 3: Click Calculate
Press the Calculate button to instantly determine your ABV.
Step 4: View Results
The calculator will display the ABV as a percentage, rounded to two decimal places, ensuring easy reading and precision.
Step 5: Copy or Share Results
You can click Copy Result to save your ABV or Share to send it to others, making collaboration and record-keeping easier.
Step 6: Reset if Needed
Click the Reset button to clear the fields and calculate ABV for a new batch.
Practical Examples of Using the ABV Gravity Calculator
Example 1: Homebrewing a Pale Ale
- OG: 1.055
- FG: 1.012
Calculation:
(1.055 − 1.012) × 131.25 = 5.61% ABV
This allows the homebrewer to understand the alcohol strength of their Pale Ale, ensuring it matches the intended recipe.
Example 2: Calculating ABV for a Stout
- OG: 1.080
- FG: 1.020
Calculation:
(1.080 − 1.020) × 131.25 = 7.88% ABV
This is particularly useful for brewers who want to monitor alcohol levels to comply with legal regulations or recipe requirements.

Frequently Asked Questions (FAQs)
1. What does ABV mean?
ABV stands for Alcohol by Volume and represents the percentage of alcohol in a beverage.
2. What is Original Gravity (OG)?
OG measures the density of the wort before fermentation, indicating the potential alcohol content.
3. What is Final Gravity (FG)?
FG measures the density of the beer after fermentation, showing how much sugar has been converted into alcohol.
4. Can I use this calculator for wine or cider?
Yes, the calculator works for any fermented beverage where OG and FG can be measured.
5. What happens if OG is lower than FG?
