Heart BPM Calculator

1. Calculate BPM from Count

Count your pulse for a specific number of seconds and enter the values below.

10 seconds
15 seconds
30 seconds
60 seconds (1 minute)

2. Target Heart Rate Zone Calculator

Find your ideal heart rate ranges for exercise based on your age.

Understanding Your Heart Rate (BPM)

Your heart rate, or pulse, is the number of times your heart beats per minute (BPM). It is a vital indicator of your overall health and cardiovascular fitness. Whether you are an athlete monitoring training intensity or simply keeping an eye on your resting vitals, understanding these numbers is essential.

How to Use the Heart BPM Calculator

There are two ways to use this tool:

  • Manual Pulse Calculation: Find your pulse (at your wrist or neck), count the beats for a set period (like 15 seconds), and enter those numbers. The calculator will normalize it to a 60-second value.
  • Target Zone Calculation: Enter your age to determine your Maximum Heart Rate and the specific zones for moderate and vigorous exercise.

What is a Normal Resting Heart Rate?

For most adults, a normal resting heart rate ranges from 60 to 100 beats per minute. Highly trained athletes may have resting heart rates as low as 40 to 50 BPM because their heart muscle is in better condition and doesn’t need to work as hard to maintain a steady beat.

Exercise Intensity Zones Explained

The American Heart Association generally recommends two main intensity levels:

  1. Moderate Intensity: 50% to 70% of your maximum heart rate. Ideal for long-duration activities like brisk walking or light cycling.
  2. Vigorous Intensity: 70% to 85% of your maximum heart rate. This range is common for running, HIIT, or competitive sports.

Real-World Example

If you are 40 years old, your estimated maximum heart rate is 180 BPM (220 – 40). To exercise in the moderate zone, you would aim for a pulse between 90 and 126 BPM. If you count 25 beats over 15 seconds during your workout, your current rate is 100 BPM—putting you right in the moderate intensity range.

var maxHR = 220 – age;
var modMin = Math.round(maxHR * 0.50);
var modMax = Math.round(maxHR * 0.70);
var vigMin = Math.round(maxHR * 0.70);
var vigMax = Math.round(maxHR * 0.85);
