If this is your first visit, please see important notes underneath the fill-in form. Bottom line is that this is just a rough estimate! I recommend putting in 35 for VO2 max if you don’t know it. Leaving VO2 max blank gives a high estimate!
After a comment from a reader, I made the following change for Women without VO2max: changed “- 0.1263 x weight” to “+ 0.1263 x weight”. The reader noticed that calories burned went down with increasing weight. But that doesn’t make sense. So I compared the numbers to the men’s formula, and I think that should be a plus. The original page I got the formula from is here. Now it seems like it’s calculating too many calories for me, but oh well…
Quite a few folks are telling me that this gives a much higher number than their heart rate monitors say for calories burned. One guy pointed out that he thinks the formula uses 60 for VO2 max if you don’t input anything in for that, and that’s a super high V02 max, like what Lance Armstrong has! I recommend putting in 35 for V02 max if you don’t know it.

Based on the following formulas: Using VO2max Men: C/min = (-59.3954 + (-36.3781 + 0.271 x age + 0.394 x weight + 0.404 x VO2max + 0.634 x HR))/4.184 Women: C/min = (-59.3954 + (0.274 x age + 0.103 x weight + 0.380 x VO2max + 0.450 x HR)) / 4.184 Without VO2max Men: C/min = (-55.0969 + 0.6309 x HR + 0.1988 x weight + 0.2017 x age) / 4.184 Women: C/min = (-20.4022 + 0.4472 x HR + 0.1263 x weight + 0.074 x age) / 4.184 weight is in kg
