Infusion Calculators: IV Flow and Drip Rates

Use these infusion calculators to work out IV fluid flow in milliliters per hour and drip rates in drops per minute. The IV Flow Rate calculator uses fluid volume and infusion time, while the IV Drip Rate and IV Drops Per Minute calculators also account for the tubing drop factor. These tools are for nurses, students, and other healthcare professionals preparing or checking an infusion calculation. Always verify the prescribed volume, duration, and tubing specifications, and follow your facility’s protocols before administering fluids.

IV Drops Per Minute

Calculate the IV drip rate in drops per minute from the total volume (mL), drop factor of the IV set, and infusion time. Essential for manually regulating intravenous fluid administration.

IV Flow Rate

Calculate the IV flow rate from the volume of fluid, infusion time, and a flow factor. Enter the values to get the rate in mL/hr, L/hr, or drops per minute.

IV Drip Rate

Calculate the IV drip rate in drops per minute (gtt/min) from the volume to infuse, the drop factor of the IV set, and the infusion time. Designed for manual gravity infusions without an infusion pump.
