Rake question

[Harmonica]

Hi

I have been playing at eurobet and have got 25% rakeback there, and was amazed
to find out that I had paid about $25 in rake after only playing 500 hands at
0.1/0.25 no limit 10 person, and I don’t know how this figure is possible. I
have always been of the opinion that if your playing low limits you wont really
generate that much rake and if your playing at high limits then what do you care
if you have to pay out $3 out of a $2000 pot. Could someone please help me out
with the issue of rake, how is it calculated?, because I have seen at certain
affiliate’s site a calculator that works this for you, but I’m not sure how
accurate that is ie is it just a ploy to get you to sign up through them.

Thanks in advance
