220 - age

190 bpm

Tanaka

187 bpm

208 - 0.7 x age

Use

Estimate

Individual variation is normal.

Training estimate only

Use max heart rate formulas carefully

Max heart rate estimates are useful for training-zone planning, but two people the same age can have different true maximums.

Training-zone setup

Use the estimate as a starting point, then build zones and compare them with how workouts actually feel.

Formula comparison

Compare 220-age and Tanaka to see a reasonable range instead of over-trusting one formula.

Fitness watch setup

Enter a tested max heart rate if you have one; otherwise use the estimate as a temporary baseline.

What this health estimate cannot tell you

  • It is not a cardiac clearance test or a safety limit.
  • It does not account for symptoms, medication, medical history, heat, or current fitness.
  • Real max heart rate can differ meaningfully from formula estimates.

When to use professional guidance

  • Stop exercise and seek care for concerning symptoms such as chest pain, fainting, or unusual shortness of breath.
  • Ask a professional before high-intensity training if you have heart disease risk factors or health concerns.

About this calculator

Maximum heart rate (Max HR) is an estimate of your highest achievable heart beats per minute during intense exercise. Many training zone calculators use Max HR as the baseline.

This tool provides estimates using common formulas like 220 - age and Tanaka (208 - 0.7 x age). These are population-level estimates and can vary significantly by individual.

For training zones, use the Heart Rate Zones calculator and choose which Max HR estimate you want to use (or enter your own tested Max HR).

How the health estimate is built

A short explanation of the model, formula, or input logic behind the health-related estimate.

  • Formula 1: 220 - age (simple and widely known).
  • Formula 2: Tanaka: 208 - (0.7 x age) (often used as an alternative).
  • Both formulas provide an estimate, not a guaranteed personal maximum.
  • Your real Max HR can differ due to genetics, training status, and testing method.

Model, formula, and limits

These are the health-model assumptions, formulas, and interpretation limits used by this calculator.

  • Formula 1: 220 - age (simple and widely known).
  • Formula 2: Tanaka: 208 - (0.7 x age) (often used as an alternative).
  • Both formulas provide an estimate, not a guaranteed personal maximum.
  • Your real Max HR can differ due to genetics, training status, and testing method.

Educational use cases

Use these examples for awareness and discussion prep, not diagnosis or treatment decisions.

  • Setting training zone baselines
  • Understanding how age affects Max HR estimates
  • Quick reference for cardio planning
  • Comparing different Max HR formulas
  • Building heart rate zone charts
  • Education (learning basic HR formulas)
  • Planning interval training intensities
  • Fitness coaching discussions

How to enter health inputs

  • Enter your age.
  • Calculate to see estimated Max HR from common formulas.
  • Use the value as a training reference estimate.
  • Open Heart Rate Zones calculator to see zone ranges.

Health interpretation mistakes

The biggest risk is treating an educational output as medical advice or ignoring missing clinical context.

  • Assuming the estimate equals your true Max HR.
  • Using Max HR as a medical fitness clearance.
  • Ignoring symptoms and pushing too hard because a formula suggests it.
  • Confusing resting heart rate with maximum heart rate.
  • Using a formula without considering individual variation.

Health caution notes

  • Use formulas as a starting point, then adjust based on real training response.
  • If you have health concerns, consult a clinician before intense exercise.
  • For zones, use percentages of Max HR as a simple method, but note it is not the only training model.
  • If you have a tested Max HR from a professional test, use that for zones instead of formulas.

FAQ

Is 220 - age accurate?

It is a simple estimate. Many people are above or below this value. Use it as a starting point.

Which formula should I use?

Either can be used for a starting estimate. Tanaka is a commonly cited alternative. The best choice is a tested Max HR if available.

Can I find my true Max HR without testing?

Not precisely. Field tests exist but carry risk. If unsure, consult a professional.

Does fitness level change Max HR?

Fitness improves performance but does not reliably increase Max HR. Max HR is largely genetic.

Is Max HR the same as target heart rate?

No. Target heart rate zones are ranges derived from Max HR (or other models).

Is it safe to train at high heart rates?

Safety depends on health status. If you have concerns, get medical advice before high-intensity training.
