I know there are several threads about budget and money in Ireland and United Kingdom. But I still didn't really manage to find answers to my questions.
I will probably be travelling around in United Kingdom and Ireland in the end of august/early september. I was looking for more information how to travel there on a shoestring. As I am planning to buy an interrail pass (even if I'll fly to and from United Kingdom), I found a site where you can calculate your daily costs. But I found it a little bit weird. As the site tells me that it becomes more expensive the older you are. Even if I decide to live cheap (use a tent, cook my own food, no reservation fees on the trains etc), it is more expensive for someone who is 30 years old compared to someone who is 18. Okay, in this case it's just 3 euros more.
I am travelling alone, am 23 years old. As Ireland and United Kingdom are expensive countries, I chose that option. Am planning to cook my own food and stay at hostels. Apparently, it would cost 34 euros per day. Would that be pretty ok? Seeing as it is just food and accommodation (and well, transportation is basically "free" if I have an interrail pass and don't pay for reservations). As most trains in Ireland and United Kingdom don't require any reservations anyway. I also know that I should add money for rail pass and pocket money.
Oh, the page can be found here. May be useful so that everyone knows what I am talking about.

I also wonder if anyone explain why the age matters, as it apparently becomes expensive when people get older. Even if they eat and live exactly the same like a younger person. Because it confuses me, and I have no idea how much I shall rely on that site and the calculations. So what do you say?
According to FAQ, I would need around 50 euros per day ("As a thumb of a rule you should calculate a minimum of 30 Euros/day to enjoy your trip. With thes budget, you´ll be generally staying at hostels, campgrounds etc. Add another 20 Euros/day to allow yourself a decent lunch or dinner from time to time." ).
Does it mean I can rely on that site's calculation and then add 16 euros and use it as pocket money? Or did I misunderstand the FAQ? Is there any way I am able to travel around in United Kingdom and Ireland cheaper (with a daily budget under 50 euros)? I also did a research on this forum and checked other treads, and apparently it is better to have a daily budget on 65 euros in Ireland, and 60 euros in United Kingdom. I don't include the cost of interrail pass and ferries to/from Ireland in my daily budget. Or would it be asking too much as Ireland and United Kingdom are known for being expensive?
I have actually travelled by train in England before. As I visited London, York, Oxford, Windsor and Reading last summer. Including transportation (tube in London and railpass), food, sightseeing and accommodation, then I spent around 55 euros per day. In total, I spent around 30 euros per day on food, sightseeing and accommodation. Then it was a really tight budget. But I actually managed to enjoy the trip. But this time, I won't add railpass and ferries in daily budget. Can I somehow use my previous experience of travel cheaply in United Kingdom (and Ireland), or is it better if I spend more money (around 50 euros per day as it is recommend?) End of august/early september is most likely still peak season over there as well, which affects the prices/costs, I think
