I've seen this '50/30/20 rule' recommend before, in the UK press (financial articles) and by banks [1] and financial resources.
I'm interested in it's origin, whether it still holds true today (is the advice still valid) and alternatives strategies for comparison (given today's current economical climate, rising inflation and interest rates).
given that it's a 1/3 rule elsewhere, it would be interesting to know indeed. it's split a bit differently than your link, but it's a third of your after-tax income to go toward living expenses, a third toward your home and the last third toward savings and investments.
