Calories Calculator
Calculate the estimated calories per 12 oz. serving of your homebrew using your Original Gravity and Final Gravity readings.
Estimate calories per 12 oz serving from gravity readings
Use the calories calculator to estimate calories in finished beer from original gravity and final gravity readings.
Example calorie estimate
For a beer with 1.050 OG and 1.010 FG, enter both gravity readings to estimate calories per 12 oz serving.
- Enter original gravity from before fermentation.
- Enter stable final gravity from after fermentation.
- Use the result as an approximate per-serving estimate.
Watch for: The calculator estimates beer calories from gravity; additions after fermentation can change the real serving value.
Frequently asked questions
What readings are needed?
You need original gravity and final gravity, the same readings used for ABV estimation.
Is this nutrition-label accurate?
No. It is a homebrew estimate, not a lab-tested nutrition panel.
Why does final gravity matter?
Final gravity reflects remaining extract and helps estimate calories left in the finished beer.
Should I correct gravity readings first?
Yes, temperature-correct hydrometer readings when they were taken far from calibration temperature.
