IV Drip Rate Calculator
Calculate IV infusion drip rate in gtt/min and pump rate in mL/hr from volume, time and drop factor. Education/reference only.
What Is the IV Drip Rate Calculator?
The IV Drip Rate Calculator works out how fast an IV should run — both the manual drip rate in drops per minute (gtt/min) for gravity sets and the pump rate in millilitres per hour (mL/hr). Enter the volume to infuse, the time, and the tubing's drop factor (10, 15, 20 or 60 gtt/mL) and it applies the standard formula. This is a reference and education tool only and must not be used for real-world clinical decisions — always confirm with a licensed clinician, the drug label and your institution's approved protocols.
How It Works
Enter the volume, infusion time and the tubing drop factor. The drip rate and pump rate update instantly.
When to Use It
As a nursing-school study aid or quick reference to check the drip-rate formula and units. Never as the basis for an actual infusion — always verify against your protocols and pump.
Frequently Asked Questions
- What's the formula?
- Drip rate (gtt/min) = (volume in mL × drop factor in gtt/mL) ÷ time in minutes. Pump rate (mL/hr) = volume ÷ time in hours.
- Can I use this for real patients?
- No. It's an educational reference only. Always confirm dosing and rates with a licensed clinician, the pump, and your institution's approved protocols.
