I followed the 50/30/20 rule religiously for about a year before realizing it was making my finances worse, not better.

The problem: in a high cost-of-living city, my 'needs' were already 65% of income. Rent alone was 40%. No amount of optimization was going to fix that within the 50% cap. The rule made me feel like a failure every single month.

What I switched to instead: I start with my savings targets first (paying myself first), then look at what's left and optimize from there. I track spending by category but don't hold myself to arbitrary percentage rules. The goal is to hit my saving targets and not increase spending year-over-year after accounting for inflation.

The 50/30/20 rule is a useful starting framework for someone new to budgeting. But if your housing costs are high or your income is variable, rigid percentage rules can work against you.
