Enter the diastolic blood pressure (mmHG) and the systolic blood pressure (mmHG) into the Calculator. The calculator will evaluate the Average Blood Pressure. 

Average Blood Pressure Formula

The following two example problems outline the steps and information needed to calculate the Average Blood Pressure.

ABP = (2*DBP + SBP) / 3


  • ABP is the Average Blood Pressure (mmHG)
  • DBP is the diastolic blood pressure (mmHG) 
  • SBP is the systolic blood pressure (mmHG) 

To calculate Average Blood Pressure, multiply the diastolic blood pressure by 2, add the systolic blood pressure to the value, then divide the result by 3.

How to Calculate Average Blood Pressure?

The following steps outline how to calculate the Average Blood Pressure.

  1. First, determine the diastolic blood pressure (mmHG). 
  2. Next, determine the systolic blood pressure (mmHG). 
  3. Next, gather the formula from above = ABP = (2*DBP + SBP) / 3.
  4. Finally, calculate the Average Blood Pressure.
  5. 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.

diastolic blood pressure (mmHG) = 50

systolic blood pressure (mmHG) = 83

ABP = (2*DBP + SBP) / 3 = ?
