Exercise bike - most accurate calories? Help please!

I've started using an exercise bike, cycling along to instructions from a spinning app. The app says I've burned X calories, the bike says Y, but neither take into account my height, weight, etc. I know the most accurate way to monitor my calories would be to invest in a heart rate monitor, but is there a way to accurately track these calories without investing in an expensive bit of kit?

Thanks.

Type it into MFP exercise to see. At least this site takes your weight and height into account.

Without your height, weight and age, it's hard to estimate (all methods are estimates). What matters is that you pick ONE source of data and use that. There are too many factors that go into figuring this out; metabolic testing is the only way to be exact.

Thanks everyone.

I just typed 40 minutes of spinning into MFP & it said 233 calories. Does this mean that everyone who entered this would have a different reading?

It's just that the spinning FAQ website says that the average person should burn 400-600 in a 40 minute class, so which sounds right to you?
