What Is a Tube Feed Calculator?
A Tube Feed Calculator is an online tool designed to estimate:
- Total daily calories provided by tube feeding
- Volume per feed for bolus schedules
- Flow rate (ml/hr) for continuous feeding
Instead of doing manual math, you enter details like daily fluid volume and formula concentration (kcal/ml). The calculator then shows the results instantly, making it much easier to manage feeding plans.
Why Tube Feed Calculations Matter
Nutrition is medicine. For patients relying on tube feeding, even small errors in calculation can lead to:
- Underfeeding, causing weight loss, fatigue, and slower recovery
- Overfeeding, which may lead to discomfort, aspiration risk, or metabolic issues
That’s why healthcare teams rely on clear numbers when planning feeding schedules. A Tube Feed Calculator ensures accuracy and consistency, giving caregivers peace of mind.
Feeding Methods: Continuous vs Bolus
Tube feeding can be done in two main ways:
1. Continuous Feeding
- Formula is delivered slowly over many hours using a pump.
- Flow rate (ml/hr) is the key number to calculate.
- Common for patients who need steady nutrition and have difficulty tolerating large volumes.
2. Bolus Feeding
- Larger amounts are given several times a day, similar to mealtimes.
- Volume per feeding is the most important calculation.
- Often used for patients who want flexibility and a more natural eating rhythm.
The calculator adapts to both methods automatically, giving you tailored results.
How to Use the Tube Feed Calculator (Step by Step)
- Enter the total daily fluid volume (ml).
Example: 2000 ml. - Enter the formula concentration (kcal/ml).
Most standard formulas are 1.0 kcal/ml, but some are 1.2 or higher. - Choose your feeding method.
- If Continuous, enter how many hours per day feeding will occur.
- If Bolus, enter the number of feedings per day.
- Click Calculate.
The calculator will display:- Total daily calories
- Flow rate (for continuous) OR Volume per feed (for bolus)
- Review results.
Adjust numbers if needed based on tolerance or professional recommendations.
Example Calculation
Let’s say a patient needs:
- 2000 ml/day total volume
- Formula concentration of 1.0 kcal/ml
- Continuous feeding over 20 hours
The calculator gives:
- Total Daily Calories: 2000 kcal
- Flow Rate: 100 ml/hr
For bolus, if the same 2000 ml/day is divided into 4 feedings:
- Total Daily Calories: 2000 kcal
- Volume Per Feed: 500 ml
Benefits of Using the Tube Feed Calculator
✔ Saves time and reduces math errors
✔ Supports both continuous and bolus methods
✔ Provides quick calorie and volume insights
✔ User-friendly and accessible online
✔ Helps healthcare workers and caregivers stay confident in feeding plans

While this calculator is accurate for general use, it is not a replacement for professional medical advice. Always confirm results with a doctor, nurse, or dietitian before making changes to a feeding plan.
