The Framework
The 50/30/20 Rule
The most proven framework in personal finance divides after-tax income into three buckets: needs, wants, and savings. It requires no spreadsheet and works across nearly every income level.
Your needs — housing, utilities, groceries, transport — should consume no more than 50% of take-home pay.
Wants cap at 30%. The remaining 20% is non-negotiable.
