For “How to get your max heart rate”, the linked Max Heart Rate Calculator is relevant because Estimate your maximum heart rate using four well-known age-based formulas.
What this specific question is asking
Most wrong answers here are setup errors, not math errors. Confirm age (years) — units, periods and definitions — before you touch Max Heart Rate Calculator, and keep the output's unit attached when you use it.
Test the setup before trusting the output: rerun the example with a doubled age (years) and see whether the result behaves as the formula implies. Direction first, precision second.
Inputs to verify
- Verify age (years) 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 maximum heart rate.
- Press Calculate to see four max-HR estimates.
- Compare Fox, Tanaka, Gulati, and Nes values.
- Use the range as a rough ceiling, not an exact figure.
Worked example and sanity check
As a worked reference for “How to get your max heart rate”, Worked example Using 220 − age, a 40-year-old's estimated max is 220 − 40 = 180 bpm (a rough population average).
Interpreting the result
Interpretation starts with magnitude. The worked example landed at 220 − 40 = 180 bpm (a rough population average); compare yours before trusting the decimals. If the two disagree wildly, the setup — usually age (years)'s unit or period — is the suspect. 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.
Verify any current tax threshold, lender rate, provider rule or health guidance with the authoritative source before acting.

Common questions
Which inputs matter most for how to get your max heart rate?
The key inputs are Age (years). Match their units and periods before using Max Heart Rate Calculator.
How can I check an answer for how to get your max heart rate?
