What this specific question is asking
Most wrong answers here are setup errors, not math errors. Confirm your age (years) and resting pulse (bpm) — optional — units, periods and definitions — before you touch Heart Rate Calculator, and keep the output's unit attached when you use it.
Validate by perturbation: nudge your age (years) by ten percent and watch the output. A result that barely moves — or jumps wildly — usually means a wrong unit or period, not a broken formula.
Inputs to verify
- Verify your age (years) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
- Verify resting pulse (bpm) — optional before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Step-by-step check
- Enter your age in years to estimate max HR.
- Optionally enter your resting heart rate for personalised zones.
- Press Calculate to see your max HR and zones.
- Use zones as a guide, not a medical limit.
Worked example and sanity check
As a worked reference for “How To Check Heart Rate On Ecg”, Worked example A simple max-heart-rate estimate is 220 − age. At 30, that's 220 − 30 = 190 bpm , with moderate exercise around 50–70% of it.
Interpreting the result
The output is only useful against a reference. The example's 220 − age gives that reference: your own result should be explainable against it — larger or smaller for a reason you can name. Treat the number as a screening estimate for orientation, not a diagnosis or a personalised prescription; individual measurement error and physiology dominate any formula's precision.
