How to use the Target Heart Rate Calculator
Estimate target heart rate from age, maximum heart rate formula, intensity method with the Target Heart Rate Calculator. It includes Estimated Max Heart Rate, Tested Max Heart Rate workflows, so choose the one that matches the values you actually know. Use it to understand an educational estimate and the inputs behind it, not as a diagnosis or treatment decision.
Step by step
- For the Target Heart Rate example, select Estimated Max Heart Rate and enter age, maximum heart rate formula, intensity method, intensity. Keep each value in the unit displayed beside its field.
- Review the selected Target Heart Rate workflow and inputs, then read target heart rate in the result panel.
- Change one Target Heart Rate assumption at a time to compare scenarios. Use Reset to restore this tool's worked example values.
How the calculation works
Selectable maximum-heart-rate equations with percent-max or Karvonen heart-rate-reserve targets.
Worked example
To reproduce the Target Heart Rate worked example, reset the calculator. Select the Estimated Max Heart Rate workflow. Use age 35 years; maximum heart rate formula Haskell-Fox; intensity method Percent of maximum; intensity 70 %. The result is target heart rate of 130 bpm. Percent of maximum heart rate at 70%. Review the displayed units before comparing the result.
Understanding the result
The Target Heart Rate reports target heart rate. Use it to understand an educational estimate and the inputs behind it, not as a diagnosis or treatment decision. Educational estimate only; it cannot diagnose a condition or replace advice from a qualified health professional.
How to check the answer
Check the Target Heart Rate estimate by confirming the units and supported ranges for age, maximum heart rate formula, intensity method. Compare target heart rate with another published method or direct measurement when available, and ask a clinician before using it for a health decision.
