Age-predicted maximum = 220 − age; target boundaries = predicted maximum × selected intensity percentages.
The 220 − age method is a broad population estimate. Medication, health status, fitness, environment, and individual measured maximum can materially change an appropriate range.
This target-heart-rate calculator keeps the age formula and intensity percentages visible. It is a broad exercise reference, not a diagnosis or individualized training prescription.
Use case
Use the broad 220 − age reference and visible target percentages without treating the result as medical clearance or individualized training advice.
Estimate an adult age-predicted target heart-rate range with editable intensity percentages.

Heart Rate Zone Calculator helps you check a specific fitness & sports question with figures that apply to you. Estimate an age-predicted maximum heart rate and target beats-per-minute range using editable intensity percentages. Use the broad 220 − age reference and visible target percentages without treating the result as medical clearance or individualized training advice. Estimate an adult age-predicted target heart-rate range with editable intensity percentages. The page keeps the method and limits visible so the result can be understood, compared, and checked instead of treated as an unexplained answer.
Prepare Age, Lower intensity and Upper intensity. Enter an adult age. Review or adjust the lower intensity percentage. Review or adjust the upper percentage so it remains above the lower value. Compare the estimate with clinician or coach guidance when personal health or performance matters. Keep units, dates, currency, and time periods consistent.
The stated method is: Age-predicted maximum = 220 − age; target boundaries = predicted maximum × selected intensity percentages. Change one assumption at a time to see which input drives the result, then compare scenarios on the same basis.
The 220 − age method is a broad population estimate. Medication, health status, fitness, environment, and individual measured maximum can materially change an appropriate range. Not medical advice. Ask a qualified clinician about exercise intensity if you have symptoms, cardiovascular risks, pregnancy, medication effects, or a medical condition.

Clear calculation guide
This free Heart Rate Zone Calculator keeps the values and the calculation method visible instead of returning an unexplained number. Estimate an age-predicted maximum heart rate and target beats-per-minute range using editable intensity percentages. Use it to check a scenario with the figures that apply to you.
Start by checking units, dates, decimal places, and the option you selected. This target-heart-rate calculator keeps the age formula and intensity percentages visible. It is a broad exercise reference, not a diagnosis or individualized training prescription. The stated mathematical method is: Age-predicted maximum = 220 − age; target boundaries = predicted maximum × selected intensity percentages.
Change one assumption at a time to understand what moves the result, then keep any final record or institution-specific rule separate from the arithmetic. The 220 − age method is a broad population estimate. Medication, health status, fitness, environment, and individual measured maximum can materially change an appropriate range. Hesaplayın is a clear, browser-based calculator for checking the maths behind your decision.
