Feeding Tube Calculator (3 Super Easy Steps!)

When you are stressed or overwhelmed, doing math can be a chore, especially when it comes to calculating a feeding tube rate. Unfortunately, our doctors and nutritionists sometime only give us some of the information we need, and we have to fill in the blanks.

To help, we have set up some super easy calculators to help make using a feeding tube pump super easy in 3 steps!

Step 1. How to Calculate ML for Tube Feeding?

In order to help you figure out the rate that your feeding tube pump needs to be set at, we need to start with how my MLs are in the total feed. Simply start by entering the total OZ that are required for the feed period. For Example, how many ML in 3 oz?

(If you already have this information, you can jump to step #3)


Step 2. How to Calculate Hours for Tube Feeding?

If your feeding schedule is a set number of house like 3 hours, you can go ahead to Step #3.

If you happen to have a time frame that is not a set number of hours, for instance, if you want to run feeds over 2 hours and 15 minutes, then use this calculator to get your updated hours in a decimal to use Step # 3.


If you choose a number of minutes that is not 15, 30, or 45 minutes, it will give you a long decimal number. You will want to round this to 2 spots. For example: 6 hours and 35 minutes will tell you it is 6.5833333333 hours. You will want to use 6.58 hours.

Step 3. How to calculate tube feeding rate?

We will now calculate how long it will take to run your feed. This is the number listed as Rate for your Feeding Tube Pump. For instance, if you need to run 90ml over 3 hours, what rate will you need?


Do you have the Dose and Rate but need the Time?

In some instances, you will be given a dose amount and a rate, but will need to figure out how much time will be needed to run the feed. For example, if you are trying to get more volume over time, your doctor may tell you to start at 30ml per hour for a total of 240ml per feeding session. How long will this run?
