Why is there no way to find out cancelation fees

Good day<br> <br> I have been searching everywhere for how much it would be to cancel my gym membership. <br> <br> I would think that this type of information should be made clear on on the terms and conditions or on the contract or something.. Instead of just saying a reasonable cancellation fee. What constitutes reasonable.? <br> <br> I am a student, the fees I'm paying now for my gym membership are not reasonable according to me, SO what is reasonable.?<br> <br> And why isn't this \Reasonable"allocated a number or a percentage or a maths equation I can work out to get to my cancellation fee"
