Question: is there a student site like www.entitledto.com that works out how much we could get?
Answer: You will only find out for certain what you are getting once you have submitted your finance application and your local authority has assessed your parents income. Once this has been done (it takes a fair few months i'm afraid) they will send you a letter listing how much money you will receive in 3 installments spread throughout the academic year.
Hope this helps!

It depends on where you're from, are you at uni or college?
If you're at uni in Scotland i know you can get an estimate from SAAS.
I presume there will be a similar site to that for England but I really don't know what it's called.
If you're at college it will be EMA up to £30 each if you are under 18 on the first day of your course. If you are over 18 on the first day of your course you will then recieve a bursary, based on parental income if you are under 25 or own your own income if over 25 or married.
Like i say though this is how it generally works, i only know the basis to how it works in Scotland and have a rough idea how it works in England.
If you need anymore help feel free to message me.
Hope that helped x
