Budgeting Methods & Fundamentals
The first book to read on budgeting. It explains why most budgets stop working, how to build one from take-home pay, how to time bills to paydays, and how the main methods (50/30/20, envelopes, zero-based and values-based planning) compare, so you can choose one you will keep.

What you will be able to do
- Build a budget from your real take-home pay and set up accounts and automatic transfers that put saving first.
- Map your month's cash flow, find its low point and build a buffer that ends timing problems.
- Apply the 50/30/20, envelope and zero-based methods, and adapt them when your numbers do not fit.
- Plan for irregular costs with sinking funds and for irregular income with a holding account.
- Choose a method that fits how you handle money, test it for a month and keep it working as your income changes.
