How to calculate iv drip rate
This calculator finds IV drip rate in drops per minute from fluid volume, drop factor, and infusion time.
How the calculation works
Drip rate = (Volume × Drop factor) ÷ (Time in hours × 60).
Example
1,000 mL over 8 hours with a 15 drops/mL drop factor: (1,000×15)÷(8×60) = 15,000÷480 ≈ 31.25 drops/min.

Pro Tips for IV Drip Rate
- Drop factor varies by IV tubing set (commonly 10, 15, 20, or 60 drops/mL) — use the specific value printed on your tubing packaging.
- This is a clinical calculation — always follow your institution's protocols and have calculations double-checked per standard practice.
Common IV Drip Rate Mistakes to Avoid
- Using the wrong drop factor for the specific IV tubing set in use, which directly changes the calculated drip rate.
