Personally, I find it interesting that people associate being on good money with outgoings, I associate it with the salary solely, and for me I would say good money starts at £3000 net if you don’t live in a capital city.
I am technically on “good money” salary wise and I am also mortgage free, and in a low cost of living city, but ironically even if I earned minimum wage and could still live quite well due to the low COL and being mortgage free I wouldn’t ever say I am on “good money” if I earned minimum wage, I would, at best, say I am in a “comfortable financial position”, which for me confirms that I see being on good money as what the person brings in money wise and not their overall financial situation.
Equally, I am on good money but if I had a high mortgage, high childcare or private school fees and lived in central London, I might still be on good money but in a tight financial position. So for me a good salary remains a good salary and a bad one a bad one and one’s outgoings and financial position remains a separate issue and one should be able to judge if someone is on good money based on salary figure even if their salary might lead to a good or tight financial position based on their outgoings/personal situation.
Like for me 100k will always be being on good money even, if it might be tight in London for the sole reason that most people don’t earn that and so it would feel weird to imply that someone on 100k isn’t on good money just because they have a £1.5million mortgage. And 18k will always be a low salary even if the person is mortgage free and barely spend anything.
