Drip Factor Calculator
Drip Rate (gtt/min) = (Volume to Infuse × Drip Factor) / Time
Example:
Volume = 1000 mL, Time = 60 minutes, Drip Factor = 20 gtt/mL
Drip Rate = (1000 × 20) / 60 = 333.33 gtt/min
💧 Drip Factor Calculator – Calculate IV Drip Rates Easily
A Drip Factor Calculator helps healthcare professionals accurately calculate the IV drip rate (in drops per minute) required to administer fluids at a desired rate. It’s commonly used in hospitals, emergency rooms, and field medicine.
📘 What Is Drip Factor?
The drip factor (also known as drop factor) is the number of drops (gtt) per milliliter (mL) delivered by IV tubing. It varies depending on the IV set:
| IV Tubing Type | Drip Factor (gtt/mL) |
|---|---|
| Macrodrip Set | 10, 15, or 20 gtt/mL |
| Microdrip Set | 60 gtt/mL |
✅ Example Calculation
Given:
- IV fluid: 1000 mL
- Time: 8 hours (480 minutes)
- Drip factor: 20 gtt/mL
Drip Rate=1000×20480=20000480≈41.67 gtt/min\text{Drip Rate} = \frac{1000 \times 20}{480} = \frac{20000}{480} \approx 41.67 \text{ gtt/min}Drip Rate=4801000×20=48020000≈41.67 gtt/min
Round to the nearest whole number:
✅ 42 drops per minute
🩺 Why Use a Drip Factor Calculator?

| 🏥 Paramedics | Useful in the field without infusion pumps |
| 📚 Students | Helps learn clinical dosage and flow calculations |
| 🧮 Clinical Techs | Saves time and reduces manual errors |
❓ FAQs – Drip Factor Calculator
🔹 What is a drip factor in IV therapy?
It’s the number of drops (gtt) per mL delivered by a specific IV tubing. It determines how fast the fluid is infused.
🔹 What is the standard drip factor for microdrip?
Always 60 gtt/mL, used when precise small-volume delivery is needed (e.g., pediatrics).
🔹 How do I know which drip factor to use?
Check the IV tubing packaging or label. Hospitals standardize sets, but values vary between 10, 15, 20, or 60 gtt/mL.
🔹 What’s the difference between flow rate and drip rate?
- Flow rate: In mL/hour (used in pumps)
- Drip rate: In gtt/min (used with gravity IV sets)
