IV Drip Rate Calculator — free online calculator.
Formula
Drip rate (gtt/min) = volume (mL) × drop factor (gtt/mL) / time (min)
- IV Drip Rate Calculator calculates its result from Time Min, Volume Ml, Drop Factor Gtt Ml. It uses the formula Drip rate (gtt/min) = volume (mL) × drop factor (gtt/mL) / time (min). Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
- The main inputs are Volume to Infuse, Infusion Time, Drop Factor. Enter them in the units and format shown in the calculator.
- Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: IV Drip Rate
Inputs
- Volume to Infuse: 1000
- Infusion Time: 480
- Drop Factor: 20
Using Time Min = 2, Volume Ml = 3, Drop Factor Gtt Ml = 4, the calculated result is 6.
