Heart Rate Zones Calculator

Estimate maximum heart rate and common moderate, vigorous, and training-zone ranges from age.

Interactive calculator

Estimate target heart rate zones by age

Use the common age-based maximum heart rate method to estimate moderate, vigorous, and training-zone heart-rate ranges.

Warm-up

94 to 113 bpm

Aerobic

113 to 132 bpm

Cardio

132 to 150 bpm

Peak

150 to 160 bpm

Results

Estimated max HR

188 bpm

Moderate zone

94 to 132 bpm

Vigorous zone

132 to 160 bpm

How to use it

  1. 01Enter your age.
  2. 02Review the estimated maximum heart rate plus moderate and vigorous zones.
  3. 03Use the detailed warm-up, aerobic, cardio, and peak bands for training guidance if they fit your program.

Result guide

  • The age-based maximum-heart-rate formula is an estimate, not a lab-measured personal maximum.
  • Moderate intensity is shown as roughly 50% to 70% of estimated max, and vigorous as about 70% to 85%.
  • Medication, heart conditions, and fitness level can change what is appropriate for you.

About this calculator

Heart-rate zone pages help people translate exercise advice into numbers they can actually use on a treadmill, bike, or watch during training.

This version uses the common age-based maximum-heart-rate estimate, which is simple and practical but still only an approximation.

Frequently asked questions

Why is target heart rate shown as a range instead of one number?

Because exercise intensity is usually guided by a target zone, not a single exact beat-per-minute value.

Does this replace exercise advice from my doctor?

No. It is a general fitness estimate and does not replace individualized medical guidance.

Can fit athletes have different real max heart rates?

Yes. The formula is only a population estimate, so an individual's actual maximum may be higher or lower.
