50/30/20 splits after-tax income into needs (50%), wants (30%), and savings or debt payoff (20%). It works because it is directional, not perfectionist.
If your fixed costs are above 50%, you have a structural problem (housing, transport) — not a latte problem. If savings are below 20%, automate the gap before lifestyle creep absorbs it.
The framework adapts: high-cost cities often live at 60/20/20; aggressive savers run 40/20/40. Pick a baseline, then adjust by life stage.
Key takeaways
- Aim for 50/30/20 as a default starting split.
- Automate the savings portion so it happens before spending.
- Adjust the ratios for your city, stage, and goals.
