Example 1
- peak 180 bpm
- after 1 min 120 bpm
60 bpm
What drop at 180 and 120? 60 bpm. 180 minus 120.
Recovery heart rate calculator
Type peak heart rate and the rate after 1 min rest. 180 minus 120 gives 60 bpm. 170 minus 140 gives 30. 190 minus 100 gives 90. The drop only, not a clinic score.
Not a clinic verdict. The calculator subtracts two bpm readings. When the drop is negative or peak is 0, the result stays blank.

How it works
HRR in this calculator is peak heart rate minus the rate after one minute of rest. 180 minus 120 = 60. The result is 60 bpm. 170 minus 140 = 30 bpm. 190 minus 100 = 90 bpm. Both values in the same units.
Field a is the peak, field b is the one-minute reading. Order matters: 120 minus 180 does not pass, because the drop would be negative and the result is a blank. Peak 0 also leaves a blank.
60 bpm at 180 and 120 is only the difference of two watch numbers. Sport sometimes uses that as a recovery sketch, not as a lab test. Another moment after the effort gives another difference.
HRmax from age lives on maximum heart rate. A percent of that maximum lives on target heart rate. There is no multiplier here. Only two bpm values and a subtraction.
Type the peak, type the one-minute reading, then Calculate. A comma in 180.5 parses. Not a training plan and not a clinic heart score.
180 minus 120 gives 60 bpm. 170 minus 140 gives 30 bpm. 190 minus 100 gives 90 bpm. A negative drop does not print a minus. It stays blank.
Formula
HRR = peak − after 1 min; blank when peak ≤ 0 or drop < 0
How to use
- Type peak heart rate, for example 180.
- Type the rate after 1 min, for example 120.
- Click Calculate. The drop is 60 bpm.
- 170 and 140 give 30 bpm. 190 and 100 give 90 bpm.
- When the one-minute reading is above the peak, the result is a blank.
180 minus 120 = 60 bpm
HRR = peak minus the rate after 1 min. 180 and 120 give 60 bpm. A negative drop stays blank.
- HRR
- The difference of two readings. 180 minus 120 shows 60 bpm. Not a percent of HRmax.
- bpm
- The unit of both fields and the result. 170 minus 140 gives 30 bpm.
- peak
- Field a. It must be positive. 190 minus 100 gives 90 bpm.

Common questions
What drop at 180 and 120?
60 bpm. 180 minus 120. The calculator rounds the result.
What does HRR mean in this calculator?
Peak minus the rate after 1 min. 170 minus 140 gives 30 bpm.
What about 190 and 100?
90 bpm. A larger drop, the same bpm unit.
What if the one-minute reading is above the peak?
The drop would be negative. The result is a blank and does not print a minus.
What if peak is 0?
A blank. Peak must be positive.
Is this a fitness score?
No. Two watch numbers. Not a clinic verdict and not a lab test.
Does field order matter?
Yes. Peak is first. Swap them and 120 with 180 leaves a blank.
Does the calculator multiply by age?
No. Two bpm values only. HRmax from age lives on another calculator.
Is 60 bpm a norm?
The calculator has no norm. It shows 60 because 180 minus 120 is 60.
Knowledge sources
The calculator subtracts two bpm readings. This is not an ECG and not a stress test.
