Activity ranges
Walking, running, resting, and the overall exercise target.
| Activity | Heart rate |
|---|---|
| Seated / resting | 60-100 bpm |
| Brisk walking | 90-126 bpm |
| Jogging / running | 126-153 bpm |
| Overall exercise target | 90-153 bpm |
For adult exercise planning only. Age-based ranges are averages. Heart conditions, medicines, pregnancy, illness, heat, dehydration, and device error can change heart rate. Seek individualized guidance when appropriate.

What does the Heart Rate Zone Calculator calculate?
The Heart Rate Zone Calculator converts the values you enter into a structured estimate using the formulas and assumptions documented on this page. Use the result to compare scenarios, review the calculation details, and identify sensitive inputs. Check the guide and formula sections before using the estimate for an important decision.
Heart Rate Zone Calculator at a Glance
- Estimates maximum heart rate from age using the 220-minus-age method.
- Shows general brisk-walking, jogging or running, and overall exercise ranges.
- Includes the American Heart Association's general adult resting reference.
- Uses height and weight only for BMI context, not to alter the heart-rate zones.
- Provides one responsive chart, a text alternative, and a downloadable PDF report.
History of Age-Based Target Heart Rates
Exercise heart-rate charts became a convenient way to translate relative intensity into a pulse range that people could check during aerobic activity. The familiar 220-minus-age equation is a broad population estimate, not a laboratory measurement of an individual's maximum heart rate.
The American Heart Association presents it as a general guide and pairs it with approximate intensity bands: 50% to 70% of estimated maximum for moderate activity and 70% to 85% for vigorous activity. This calculator follows that public guidance and keeps its limitations visible.
What This Heart Rate Zone Calculator Does
The calculator uses your age to estimate maximum heart rate, then applies published percentage bands to produce minimum and maximum targets. It labels 50% to 70% as the brisk-walking or moderate range and 70% to 85% as the jogging or running vigorous range.
Height and weight are converted into metric units and used to calculate BMI as profile context. They do not change the standard age-based heart-rate result.
Who Should Use It
This calculator is intended for adults who want a quick, transparent starting point for discussing or planning aerobic exercise intensity. It can help walkers, runners, cyclists, and gym users compare a measured pulse or wearable reading with a general age-based range.
It is not designed for children, pregnancy-specific guidance, cardiac rehabilitation, exercise clearance, or individualized targets for people whose heart rate is affected by medicines or medical conditions.
Problems It Solves
- Converts age into an estimated maximum heart rate.
- Calculates moderate, vigorous, and combined exercise ranges consistently.
- Separates resting reference values from exercise targets.
- Explains why height and weight do not change the age-based bpm formula.
- Presents the same result as metrics, a chart, a table alternative, and a PDF.
Key Benefits
The calculation is easy to audit: each result traces back to age and a published percentage. The chart places all activity ranges on the same beats-per-minute scale, while the written values remain available for people who do not use visual charts.
Heart Rate Zone Definitions
- Beats per minute (bpm)
- The number of heartbeats counted in one minute.
- Resting heart rate
- Your heart rate while awake and at rest. The displayed 60-100 bpm range is a general adult reference, not a personal target.
- Estimated maximum heart rate
- A population estimate calculated as 220 minus age. An individual measured maximum can differ.
- Moderate range
- Approximately 50% to 70% of estimated maximum heart rate.
- Vigorous range
- Approximately 70% to 85% of estimated maximum heart rate.
- Five training zones
- Consecutive 10-percentage-point bands from 50% through 100% of estimated maximum.
- BMI context
- Weight in kilograms divided by height in meters squared. It is displayed separately and does not drive the bpm ranges.
When to Use the Calculator
Use it before an aerobic workout to understand a general target range, after a session to interpret a recorded exercise heart rate, or while comparing how age changes an estimate. Recalculate when using a different age profile. Do not use it to decide whether symptoms are safe or whether you are medically cleared to exercise.
How the Calculation Works
For “How the Calculation Works,” the Heart Rate Zone Calculator organizes the relevant inputs, applies the documented method, and shows a result that can be compared across scenarios. The points below identify the specific considerations and assumptions users should review before relying on the estimate.
For a 40-year-old, estimated maximum heart rate is 180 bpm. The moderate range is 90 to 126 bpm, and the vigorous range is 126 to 153 bpm. Displayed range endpoints are rounded to the nearest whole beat per minute.
Review every equation on the heart rate formula page or reproduce three scenarios on the worked examples page.
Frequently Asked Questions
How are the heart rate ranges calculated?
The calculator estimates maximum heart rate as 220 minus age, then applies the published percentage bands for moderate and vigorous activity. For a useful Heart Rate Zone Calculator result, use realistic inputs, compare relevant scenarios, and review the stated assumptions before making a decision.
What is the walking heart rate range?
The calculator uses 50% to 70% of estimated maximum heart rate as the brisk-walking or moderate-intensity planning range. For a useful Heart Rate Zone Calculator result, use realistic inputs, compare relevant scenarios, and review the stated assumptions before making a decision.
What is the running heart rate range?
The calculator uses 70% to 85% of estimated maximum heart rate as the jogging or running vigorous-intensity planning range. For a useful Heart Rate Zone Calculator result, use realistic inputs, compare relevant scenarios, and review the stated assumptions before making a decision.
Do height and weight change target heart rate?
No. Height and weight provide BMI and profile context, but the standard age-based heart-rate formula does not use them. For a useful Heart Rate Zone Calculator result, use realistic inputs, compare relevant scenarios, and review the stated assumptions before making a decision.
Are the ranges medical advice?
No. They are adult exercise-planning estimates. Medicines, heart conditions, fitness, temperature, dehydration, and measurement error can change heart-rate response. For a useful Heart Rate Zone Calculator result, use realistic inputs, compare relevant scenarios, and review the stated assumptions before making a decision.
One Useful Heart Rate Fact
The CDC talk test offers a practical cross-check. During moderate activity, you can usually talk but not sing. During vigorous activity, saying more than a few words generally requires pausing for breath.
Conclusion
An age-based heart-rate zone is a starting estimate, not a guarantee of effort or safety. Compare the number with perceived effort, the talk test, and guidance from a qualified health professional when your health or medicines may affect your response.
This calculator provides general adult exercise-planning estimates. It is not medical advice, a diagnosis, exercise clearance, or a substitute for individualized care.
