could someone advise me on how to calculate my (sponsors) monthly outgoings for the purpose of the fiance visa.

Obviously you calcuate all your direct debits and payments, but how do you work out outgoings for general life and stuff which changes all the time.

I've been spending more money than I could live on lately just because I've had the money to do it, so my statements dont reflect my outgoings if i were to watch what i spend. Which is what i will be doing when my fiancee comes here. Will they recognise this or should I point it out?

Im just wondering do you just estimate what you think you could live on? and do a breakdown of this?

thanks.
