Estimated maximum heart rate

Enter your age to calculate it with the Tanaka formula.
This is not a target to maintain
This figure is an estimated maximum. It does not indicate a heart rate you should try to reach or sustain during exercise.

How to interpret your result
The main figure is a mathematical reference based only on your age. It is a starting point, but it does not describe your actual exercise response on its own.
Estimated maximum heart rate
An approximate limit
It represents an estimated population maximum. It is not a target for every workout or a measurement of your fitness.
Target heart rate
An intensity range
Percentages help represent general moderate or vigorous efforts, but they do not replace individual guidance.
Individual response
It can vary considerably
Sleep, hydration, temperature, stress, medication, genetics, and health can change your heart rate during activity.
Formulas used
We compare two well-known formulas to make clear that the result is an estimate, not an exact figure.
Tanaka formula
PrimaryMHR = 208 - (0.7 × age)
It is used for the main result and to calculate the general intensity ranges.
Classic formula
MHR = 220 - age
It is shown only for comparison. The difference between the two formulas is a reminder that neither predicts every person exactly.
When to seek an individual evaluation
An age-based formula does not account for symptoms, medical history, or your response during actual exertion.
A stress test can provide greater precision
A supervised test shows how your heart responds as intensity increases. A professional can determine whether it is appropriate for you and interpret the results alongside your health history.
Seek professional guidance before using exercise ranges if:
- • You have symptoms during activity.
- • You take medication that affects heart rate.
- • Tienes antecedentes cardiovasculares.
- • Necesitas objetivos personalizados.
Sources and methodology
The calculator combines a published population formula with general intensity ranges used in physical-activity education.
Frequently asked questions
What is maximum heart rate?
It is the approximate highest number of beats per minute your heart can reach during very intense effort. Age-based formulas provide a population estimate, not an individual measurement.
Is maximum heart rate an exercise target?
No. It is an estimated maximum used as a reference for general intensity calculations. It is not a heart rate you should try to reach or maintain during exercise.
Which formula should I use: Tanaka or 220 minus age?
This calculator uses Tanaka as the primary estimate and shows 220 minus age for comparison. Neither formula predicts every person's maximum heart rate exactly.
Why might my actual heart rate be different?
Your response can vary with fitness, genetics, temperature, hydration, medication, stress, sleep, health conditions, and other factors.
What is the difference between maximum and target heart rate?
Maximum heart rate is an estimated limit. Target heart rate is a range derived from that maximum to represent an activity intensity, such as moderate or vigorous.
Does this replace an exercise stress test?
No. A supervised stress test can observe your individual response and may be needed when a healthcare professional requires a more precise measurement.
