Zero-based planning as an idea

Zero-based planning means you assign every unit of income a job until nothing is left unassigned (spending, reserves, debt payments). It is an allocation idea, not a mandatory programme.

In more detail

Unlike 'whatever is left is saving', you start at zero and build the month from priorities. Surprises still need a buffer. The method does not replace cashflow timing or an emergency pot.

Background

Finmon recommends no app and no product. If you plan nothing, leaving things as they are is still a choice. Giving every euro a job before the month starts is only one tool among others. It sits next to cashflow, your reserve, and the habit of not changing anything.

An example

Pay €2,400. You assign rent, food, transport, minimum payments, €200 to reserve and the rest to a goal pot until €0 is left 'free'.

A common misconception

Zero-based means no money may remain at month end.

It means every unit of income has a job, including reserves. The account balance can and should hold a buffer.
