We don't pay for them, realistically. They bring in more money in tourism etc than they'll ever cost us.
You can't quantify their cost, because the Mountbatten-Windsors are the only citizens of these islands who are exempt from the FOI Act. They pay tax at a rate they think they will, which we are not allowed to know, and which only happened in the first place because there was a public outcry. And of course, this is what's enabled Charles to engage in his financial shenanigans with impunity, and to allow his aide to be a fall guy when his shady doings came to light.
They are a shower. No wonder they don't want their financial goings-on exposed to public scrutiny. The FOI exemption, incidentally, extends to every member of that family.
So as to value versus cost, none of us can possibly know. Because they don't want us to know. That in itself is the key problem. As to what they 'bring in', this again isn't quantifiable but it's laughable to suggest that the entire UK tourist industry is based on a family of unelected stuffed shirts. Check out the most visited tourist attractions in the UK, including the many beautiful cities outside London. We have a rich artistic, literary and cultural nation, which in Europe is probably rivalled only by Italy.
We are doing fine as a nation in our own right and on our own merits. We don't need one unremarkable, intellectually inadequate, decidedly morally dodgy family to ensure as much.
