Enter your age into the calculator to estimate your heart rate during a stress test.

Stress Test Heart Rate Formula

The following formula is used to calculate a stress test heart rate. 

STHR = 220 - A
  • Where STHR is the stress test heart rate (BPM)
  • A is your age

To calculate your stress test heart rate, subtract your age from 220.

What is a stress test heart rate?

A stress test heart rate is the rate, in beats per minute, that your heart is pumping during a stress test.

What is a stress test?

A stress test is simply a physical exercise designed to make a person reach their maximum heart rate through pure exertion. Some of these stress tests are done through sprinting, biking, or simply squatting a lightweight repeatedly.

How to calculate stress test heart rate?

The following example outlines the steps needed to calculate a heart rate someone would reach during a stress test.

First, determine your age. For this example, the person is 50 years old.

Next and last, just use the formula above to estimate your heart rate during a stress test.

STHR = 220 – A

STHR = 220 – 50

STHR = 170 BPM

This heart rate is only an estimate, the true heart rate someone reaches during a stress test can only be measured directly.
