MASSIVE difference in calories burned

My question is about calories burned.

I am using My Fitness Pal to log my daily activity.

I have an exercise bike at home, that doesn't record weight/age, but is telling me 125 cals burned for 10 minutes!!

MFP says for 10 minutes on the bike, moderate effort, is 86 cals (for my weight/age).

My sister's bike at the gym, for the same time spent, is giving half the cals burned (49 cals).

Massive differences, not sure which to go by?

    It might help people estimate which is closer if you included your age/height/weight/gender. But most people will just tell you to buy a heart rate monitor.

    Try throwing your info into http://www.healthstatus.com/calculate/cbc and see which one is close. I generally go with the lowest estimate (I run 3 GPS apps during my runs, they're always within 20 calories or so but I'd rather lowball than overestimate).

    The bike that does not take weight, age, and gender into consideration will be inaccurate. The bike at the gym and MFP will be a bit closer. Heart/activity monitor is the best way to calculate calories burned though....

    Im 162lb, female, 167cm tall and age 35yrs.

    That link you gave me says 86 cals burned for 10 minutes moderate.

    I am having trouble gauging what is considered moderate.

    If you are cycling a regular bicycle moderate is considered 12-14mph.

    I am cycling at 13mph on the stationary bike, so I guess that is moderate too?

    So yeah, 86 cals on that web link.

    I personally wouldn't worry about it, which means not 'eating back'. They're all estimates.

    I'm slightly OCD about logging my activity ''/

    I have no idea what type of HRM to get, there is a lot of difference in what's available on the market
