How it works

50/30/20
Needs / Wants / savings split, savings-first, adjustable on the Plan step.

Deterministic budget math owns every number and runs in WebAssembly on your device. Advice only verbalizes the computed Plan behind a validator. It suggests; it never moves money.

Start: step 1 Income

Past months · one currency per month, no conversion.

Three steps, guided

01 Income

Recurring income, other inflows, rollover, goal, and Emergency Fund balance.

 02 Expenses

Each expense with category and fixed, one-off, and debt-payment flags.

 03 Plan & Advice

Available minus expenses equals leftover; warnings; guarded advice.
