Drops Per Minute Calculator
Calculate IV drip rate in drops per minute for safe medication administration
Calculate IV Drip Rate
Total volume to be infused in milliliters
Duration of the infusion
Drop factor should be printed on IV set package
Drip Rate Results
Formula used: Drops per minute = (Volume × Drop factor) ÷ Time
Calculation: Enter values to see calculation
Total drops needed: 0 drops
Example Calculation
Scenario: 500 mL saline to be infused over 60 minutes using standard 15 gtts/mL IV set
Calculation: (500 mL × 15 gtts/mL) ÷ 60 min = 125 drops/minute
Result: Set IV drip rate to 125 drops per minute

Safety Reminders
Always verify calculations with another healthcare provider
Check drop factor on IV tubing package
Monitor patient response during infusion
Use electronic infusion pumps when available
Understanding IV Drip Rate Calculations
What are Drops Per Minute?
Drops per minute (gtts/min) is the rate at which IV fluid is administered through gravity-fed intravenous tubing. This measurement ensures precise medication delivery and patient safety.
Key Components
- •Volume: Total amount of fluid to infuse (mL)
- •Time: Duration of infusion (minutes/hours)
- •Drop Factor: Drops per mL (from IV tubing)
The Formula
Drops/min = (Volume × Drop Factor) ÷ Time
Clinical Applications
- •Medication administration
- •Fluid resuscitation
- •Maintenance hydration
- •Blood product transfusion
