Enter the total credit hours of study into the Calculator. The calculator will evaluate the Study Time. 

Study Time Formula

ST = CH * 2.5


  • ST is the Study Time (hours of study per week)
  • CH is the total credit hours of study

To calculate Study Time, multiply the total credit hours by 2.5.

How to Calculate Study Time?

The following steps outline how to calculate the Study Time.

  1. First, determine the total credit hours of study. 
  2. Next, gather the formula from above = ST = CH * 2.5.
  3. Finally, calculate the Study Time.
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total credit hours of study = 15


How does the number of credit hours affect my study time?
The number of credit hours directly influences your study time. According to the formula ST = CH * 2.5, for every credit hour, you should allocate 2.5 hours of study time per week. Therefore, more credit hours mean more study time.

Can I use the study time formula for online courses?
Yes, the study time formula can be applied to online courses as well. The formula calculates the amount of study time based on credit hours, which is a common measure for both traditional and online courses.

Is the study time calculated per course or for all courses in a semester?
The study time calculated using the formula is typically per course. If you’re taking multiple courses, you’ll need to calculate the study time for each course based on its credit hours and then sum them up for a total weekly study time.

What if my actual study time differs from the calculated time?
The formula provides a general guideline based on average expectations. Your actual study time might differ due to various factors such as course difficulty, personal learning pace, and prior knowledge. It’s important to adjust your study time as needed to meet your learning goals.
