DS has just finished his first year, he got minimum maintenance loan, we topped it up to pay halls fees.
We then subtracted accomodation cost from max loan figure and divided by 8.5 for total months he would be at uni. That came to about £360 a month, which is what his friends in same halls but on a full loan would have to live on each month!
We gave him 300, which he said was more than enough, but obvs less than those on full loan would have. He covered his phone and travel costs from that (but we are only 40mins away on train) and his books were free from the uni.
He did have funds from a 6th form job, plus has worked back in retail in uni city since Easter (but has just handed notice in, as it was long weekend hours, and doing a science, he will have a full 2nd year timetable.)
I have just today done same calcs for 2nd year. Since his shared house is costing less than halls, and max loan has increased, it came out at £500/month we should be giving him to make up to max loan. We may increase it a little, but not that much.
But it is interesting, if he were eligible for a full loan, he would have around £500/mth to spend after paying for his house.
