What is the Heart Rate Zone Calculator?
A heart rate zone calculator estimates maximum heart rate and training zones from age. These zones are often used to plan low, moderate and higher-intensity cardio workouts.
The common maximum heart rate estimate is simple and easy to remember, but it is not perfect for everyone. Fitness level, medication, medical conditions and individual variation can change actual heart rate response.
Use this tool for general exercise planning and awareness. If you have a heart condition, take medication that affects heart rate or are starting intense exercise, professional guidance is important.
How we calculate the result
Formula: Maximum Heart Rate = 220 - age
After estimating maximum heart rate, the calculator applies percentage ranges to find training zones. For example, a fat-burn or easy cardio zone may use a lower percentage of max heart rate, while a cardio zone uses a higher percentage.
If your estimated maximum heart rate is 190, then 60% is 114 bpm and 70% is 133 bpm. That creates a zone range rather than one exact target.
When to use this calculator
Use this calculator for cardio planning, workout intensity awareness and comparing easy, moderate and higher training zones.

Limitations of this calculator
This Heart Rate Zone Calculator is an educational estimate. It cannot replace official records, professional advice, medical advice, accounting documents, tax filings, lender statements or employer payroll records.
Real-world health example
Use Heart Rate Zone Calculator as a screening or planning number, then compare it with other signals such as energy level, body measurements, training history and professional advice. Health calculators are useful for awareness, but they do not understand every body type or medical situation.
Mistakes to avoid
Do not treat one calculator result as a diagnosis. Enter the correct units, avoid rounded guesses where possible and review unusual results with a qualified professional.
