Example 1
- HRmax = 190
- 70%
133 bpm
What target heart rate at 190 and 70%? 133 bpm. 190 × 0.70.
Target heart rate (training)
Type HRmax and a percent or a fraction. 190 and 70 give 133 bpm. 180 and 0.6 give 108. 200 and 85 give 170. One number, not the full zones.
Not a clinic verdict and not a stress test. The calculator multiplies HRmax. It does not subtract resting pulse (Karvonen).

How it works
Target heart rate in this calculator is HRmax times a factor. When field b is greater than 1, the calculator divides it by 100. 190 and 70 means 190 × 0.70 = 133. The result is 133 bpm. 200 and 85 gives 170 bpm.
A fraction stays a fraction. 180 and 0.6 is 180 × 0.6 = 108 bpm, not 180 × 0.006. Typed 70 and typed 0.7 at the same HRmax 190 both give 133, because 70 is greater than 1.
You type HRmax yourself. The 220 minus age sketch lives on maximum heart rate: age 30 is 190. The full 50, 60, 70, 80, and 90 percent marks from that same 190 live on heart rate zones.
Here one percent field, one result. There is no resting pulse, so this is not Karvonen. 133 bpm at 190 and 70% is a point on the HRmax scale, not a zone band.
Type HRmax, type 70 or 0.7, then Calculate. Zero HRmax leaves a blank. A comma in 0.6 parses. A pace sketch, not a clinic plan.
190 and 70 give 133 bpm. 180 and 0.6 give 108 bpm. 200 and 85 give 170 bpm. The same 70% at another HRmax gives another number.
Formula
result = HRmax × (b > 1 ? b/100 : b)
How to use
- Type HRmax, for example 190.
- Type 70 or 0.7. A number above 1 is divided by 100.
- Click Calculate. The result is 133 bpm.
- 180 and 0.6 give 108 bpm. 200 and 85 give 170 bpm.
- HRmax from age lives on maximum heart rate. Full bands live on heart rate zones.
190 and 70% give 133 bpm
HRmax times a percent or a fraction. 190 and 70 give 133 bpm. 180 and 0.6 give 108 bpm.
- HRmax
- Maximum heart rate in field a. 190 × 0.70 gives 133 bpm. No 220 minus age here.
- bpm
- Beats per minute. The rounded result. 200 and 85% show 170 bpm.
- zones
- The full 50-90% bands live next door. Here one factor and one number.
Examples
Example 2
- HRmax = 180
- 0.6
108 bpm
What about 180 and the fraction 0.6? 108 bpm. 0.6 stays a fraction.
Example 3
- HRmax = 200
- 85%
170 bpm
What about 200 and 85%? 170 bpm. 200 × 0.85.

Common questions
What target heart rate at 190 and 70%?
133 bpm. 190 × 0.70, then a round.
Is 70 a percent or a fraction?
70 is greater than 1, so the calculator divides by 100. 0.6 stays 0.6.
What about 180 and 0.6?
108 bpm. The fraction does not go through 100.
What about 200 and 85%?
170 bpm. 200 × 0.85.
Does the calculator compute HRmax from age?
No. You type HRmax. 220 minus age lives on maximum heart rate.
How is this different from heart rate zones?
There, five marks from age. Here one percent and one bpm result.
Is this Karvonen?
No. There is no resting pulse. Only HRmax times a factor.
What if HRmax is 0?
The result is a blank, because HRmax must be positive.
Is 133 bpm a clinic verdict?
No. A pace sketch from a product. A watch or a stress test can differ.
