The 50/30/20 rule was designed for a different era. In 2026, housing alone consumes 50%+ of income in cities like SF, NYC, Sydney, and London.
Why It’s Broken
Average rent in Manhattan: $4,400/month. On a $80K salary ($5,300 take-home), that’s 83% on housing alone. The rule never accounted for this.
What Works Instead
Reverse Budgeting
Pay yourself first: automate 20% to savings/investments, then spend the rest guilt-free. Manage your cash flow.
Adjusted Ratios
In high-cost cities: 60/20/20 or even 70/15/15. What matters is the savings rate, not the exact split.
