Enter your average heart rate (BPM) into the Cardiac Frequency Calculator. The calculator will evaluate the Cardiac Frequency. 

Cardiac Frequency Formula

The following two example problems outline the steps and information needed to calculate the Cardiac Frequency.

Fc = HR * .016667


  • Fc is the Cardiac Frequency (hz)
  • HR is your average heart rate (BPM) 

To calculate the cardiac frequency, multiply the average heart rate by .016667.

How to Calculate Cardiac Frequency?

The following steps outline how to calculate the Cardiac Frequency.

  1. First, determine your average heart rate (BPM). 
  2. Next, gather the formula from above = Fc = HR * .016667.
  3. Finally, calculate the Cardiac Frequency.
  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.

your average heart rate (BPM) = 60

Fc = HR * .016667 = ?
