Three common approaches
50/30/20
Split net income into 50% needs, 30% wants, 20% saving or debt. Good for steady incomes and quick setup.
Zero-based
Give every pound a job. Great control with a bit more admin. Works well when cash is tight or variable.
Pots (jam-jar)
Separate accounts or virtual pots for bills, fun, and goals. Visual and simple for households.
