Set Up a Simple System for Managing Money Week to Week

Running out of money before the end of the month is usually not an income problem; it is a visibility problem. You do not know what is available for discretionary spending because you have not separated it from what is already committed. The simplest system that fixes this takes one setup step and ten minutes a week, and it does not require categorising every coffee or logging into a budgeting app.

I do not have a complicated financial life but I still run out of money before the end of the month or lose track of where it goes. I do not want a full budget spreadsheet or a subscription app. Help me build the simplest possible system that: tells me how much I have available to spend on non-fixed costs after essential bills and savings, prevents the end-of-month panic without requiring daily tracking, works without needing to categorise every transaction, and takes less than ten minutes per week to maintain. I am paid [monthly / weekly / irregularly] and my fixed costs are roughly [amount or proportion of income].
