What this tool does
The split is a starting point, not a rule: where housing is expensive the needs share is simply larger, and the honest response is to lower wants rather than savings. Work from net income — what actually arrives in the account — and the daily figure gives the wants budget something concrete to push against.
Formula
50 % needs · 30 % wants · 20 % savings
