Why this page exists

Training plans often start with a rough max-heart-rate estimate when you want a simple reference point before building heart-rate zones or checking effort. This calculator helps visitors estimate maximum heart rate from age using the common 220 minus age method.

Max heart rate calculator

Estimate maximum heart rate from age using a common planning formula.

Result

185 bpm

Estimated maximum heart rate using the common 220 minus age formula.

Estimated max heart rate185 bpm

Age used35 years

Formula basis220 - age

Equivalent beats per second3.08 bps

35 years old in the 220-minus-age method points to an estimated max heart rate near 185 bpm.
This is best used as a rough training reference rather than an exact personal ceiling.
Use the result with heart-rate-zone and heart-rate-reserve tools if you want to turn the estimate into training ranges.

This is a rough training estimate, not medical advice. Real max heart rate varies from person to person and can differ from age-based formulas.

Planning note

Last updated April 16, 2026. Use this tool to compare scenarios and plan ahead, then confirm important details with the lender, employer, insurer, contractor, or other qualified provider involved in the final decision.

How it works

What the calculator is doing

Enter age.

The calculator subtracts age from 220.

It shows the estimated max heart rate and the age used.

Understanding your result

This is a rough training estimate only. It can be useful as a starting point for planning intensity, but it is not a medical measurement and individual results can vary meaningfully from age-based formulas.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Start a basic heart-rate training plan

A quick max-heart-rate estimate can help before moving into heart-rate-zone planning.

Compare the effect of age on the estimate

Changing age shows how the simple formula lowers the estimate over time.

Use it with heart-rate-zone tools

Max heart rate often becomes more practical when paired with heart-rate-zone and reserve calculators.

When to use it

Good times to run this calculator

Use this when you want a simple age-based max-heart-rate estimate as a starting point for training planning.

It is especially useful before using zone or reserve tools that ask for a max heart rate input.

Assumptions and limitations

The estimate is based on a broad rule-of-thumb formula and does not measure your true personal maximum heart rate.

Fitness level, genetics, training history, and testing conditions can all shift real max heart rate away from the formula.

Common mistakes

Avoid the usual input mistakes

Treating the formula as an exact personal ceiling can make training zones feel more precise than they really are.

Using the estimate as medical guidance instead of a general training reference can lead to over-interpretation.

Practical tips

Use the estimate as a starting point, then refine your training zones if you later get better personal heart-rate data.

Pair the result with heart-rate-zone and reserve tools so the estimate becomes more actionable.

Worked example

Walk through a realistic scenario

A worked example shows how the estimate behaves when the inputs resemble a real planning decision.

Estimate max heart rate from age

A person is 35 years old.

1. Enter 35 as age.

2. Subtract age from 220.

3. Read the result as an estimated max heart rate of 185 bpm.

Takeaway: The result gives a simple reference point that can be used in basic training-zone planning.

FAQ

Common questions

How is max heart rate estimated here?

The calculator uses the common 220 minus age formula and shows the result in beats per minute.

Is this an exact personal maximum?

No. It is a rough training estimate and real max heart rate can vary from person to person.

What should I use this estimate for?

It is most useful as a planning reference before checking heart-rate zones, reserve, or training intensity ranges.
