This heart rate zones calculator gives you a quick, general estimate of your five training zones in beats per minute. First, enter your age and, if you know it, your resting heart rate. Then use the ranges as a simple guide for pacing workouts, not as a medical target.
Use this free Heart Rate Zones Calculator to estimate your maximum heart rate and your five training zones.

Find Your Heart Rate Zones
General information estimates only.
Step 1: Enter your details
Heart rate is measured in beats per minute (bpm) for everyone. There is no metric or imperial version of age or heart rate, so no measurement-system choice is needed for this tool.
How This Heart Rate Zones Calculator Works
The tool starts with your age and estimates a maximum heart rate. Next, it splits that estimate into five zones, from the lightest effort to the hardest. For example, Zone 1 covers the lowest range, while Zone 5 covers the highest. In addition, adding a resting heart rate lets the tool adjust the ranges for you.
How to Use This Heart Rate Zones Calculator and Read Your Result
First, enter your age in years. Then add your resting heart rate if you know it, or leave that field blank. Next, click the calculate button. After that, read the table of five zones and note the beats-per-minute range for each one.
Use the range that matches how hard you plan to train. However, the numbers are estimates, so treat them as a guide. Therefore, compare them with how you feel during a session. In addition, a watch or chest strap reading can help you check whether you sit inside the range you chose.
Estimates Only, Plus a Helpful Source
These results are estimates for general information only. They are not a diagnosis, a treatment plan, or personal medical advice. Meanwhile, the American Heart Association explains target heart rates and how to check them in its Target Heart Rates Chart. In short, use the zones to plan, then listen to your body.
Heart Rate Zones Calculator Tips for Steady Training
First, warm up before you aim for a higher zone. Next, build up gradually instead of jumping straight to hard efforts. Then check your watch or pulse during the session. In addition, slow down if you feel dizzy, unwell, or unusually breathless. As a result, you keep sessions steadier and easier to repeat.
Why a Heart Rate Zones Calculator Helps With Training Plans
First, clear zones make pacing easier to judge. Next, they help you plan easy days and harder days. Then you can match a session to the effort you want. For example, use a lower zone for a gentle session and a higher zone for a short, hard effort. Finally, write down the ranges you used so you can compare sessions over time.
Finally, review your zones once more before your next session. Meanwhile, keep a note of the ranges that feel comfortable for you. As a result, your pacing decisions become easier over time.
