Fifty Thirty Twenty (Web): Elizabeth Warren's Budgeting Method

Elizabeth Warren's 50-30-20 method of budgeting

US Senator Elizabeth Warren, who is also running for President, popularized the 50-30-20 rule of budgeting in a book in 2005. Warren advises splitting your income such that you spend 50% on things you need (like rent, utilities, groceries, etc.), 30% on things you want (internet, entertainment, dining out, etc.), and 20% on savings and paying debt (student loans, retirement funds, etc.).

The system has become very popular, but how realistic is it? Fifty Thirty Twenty takes the rule and applies it to the average US citizen today. Using government-provided figures, this interactive guide shows who can and cannot live with the 50-30-20 rule, and suggests other methods too.

That said, the 50-30-20 budget is about living within your means. Even if it seems difficult, perhaps making some hard choices could make it work for you in the long term. To calculate the 50-30-20 budget for yourself, use the website's 50-30-20 Budgeting Worksheet or NerdWallet's calculator. Fill it out and you'll find where you need to cut expenses to live within the 50-30-20 rules.

Beginner's Spreadsheet (Google Docs): Redditor's Free Template

Simplest budget planning free spreadsheet for beginners

This is one of the most impressive budgeting spreadsheets I have seen, especially for how simple it is to use. Reddit user Celesmeh shared this personal spreadsheet for people who don't know how to budget. The idea is to make a daily budget for yourself, which supports long-term goals as well.

The spreadsheet, which you can copy in Google Docs and download to use offline, shows a snapshot of your daily spending limit, monthly earnings and expenditures, flex spending, and a pie chart of where your money is going. How it reaches this snapshot is the interesting part.

Each aspect of your money is broken down in the simplest format possible. Add income and expenses, credit card payments, large goals, tips, daily expenses, and almost anything else related to your money. The calculator will take care of everything. You can even rename elements or add new ones.

The spreadsheet includes detailed instructions on how to use it so you can get started immediately. If you like what you see, read Celesmeh's original post for discussions and ideas.

Paper and Excel Tracker: A Guide on Annual Personal Budgeting

Paper and Excel budget tracker for advanced budgeting

Apps aren't for everyone. Some prefer a simple paper-and-pen approach to keep track of expenditures and receipts. Reddit user WhiskeySauer put together a guide on how to do that, convert it into data on an Excel spreadsheet, and use it to budget your living.

WhiskeySauer recommends using a folder to track and store all your expenses and receipts, along with a blank page that lists every foreseeable expense already. You fill the sheet manually with a pen, which can help in crystallizing your expenditures much like writing notes can help in remembering them later.

At the end of the month, add all that data into the spreadsheet to get a snapshot of your annual budget, spending patterns, and other useful information.

Note: WhiskeySauer's spreadsheet link isn't working right now, but it would be easy to make your own Excel based on the screenshot guide, or you can wait for an updated link.
