6 Steps To Reinvent Your Budget Using The 50/30/20 Rule

Feb 28, 2023 Personal Finances

Don’t know where to start when it comes to budgeting? Take these steps to help create a budget you can stick to and that best fits your needs.

Budgeting is a skill that helps you make smart decisions with your money. It ensures you’re spending less than you earn, prepares you for life’s curveballs, and funds your goals and your dreams. Unfortunately, budgeting is often seen as restrictive and overwhelming. Financial priorities are deeply personal, so it can be challenging to find the right combination of strategies and tools that work for you.

If you’re new to budgeting or if you don’t feel confident with your current mix of budgeting tools, give proportional budgeting a try. A proportional budget divides your income into categories by percentage. It’s a simple concept to apply, it pairs well with the spreadsheets and/or apps you may already be using, and it can be easily tailored to suit your specific needs. Most importantly, it will make you think about your expenses in a completely new light.

Try the 50/30/20 budget as a starting point. It was first introduced in a book written by Elizabeth Warren and Amelia Warren Tyagi, but has since been widely adopted as an effective intro to budgeting.

Apply The 50/30/20 Rule

Step 1: Determine Your Limits

The 50/30/20 rule suggests you spend 50% of your income on needs, 30% on wants, and 20% on savings. Your first step is to calculate how much money those percentages represent for your particular financial situation. Take your monthly net income (that’s your take-home pay after taxes and deductions) and multiply it by 50%, 30%, and 20% to determine your spending limits.

For example, if your net income is $3,000 a month, you would aim to spend $1,500 a month on needs, $900 a month on wants, and $600 a month on savings.

Step 2: Track Your Spending

In order to measure your budgeting progress, you need to know where you’re at right now. Track your spending for at least two months. Capture your transactions however you like, but keep in mind that the more accurate you are, the more effective your 50/30/20 budget will be.

Step 3: Sort Your Expenses

Once you have a snapshot of your monthly spending, sort each of your expenses from the previous month into one of three categories: Needs, Wants, and Savings.

Needs are your absolute essentials. Skipping these expenses can lead to extreme hardship, job loss, illness, or legal trouble. Therefore, rent, health insurance, taxes, and credit card minimum payments fall under the needs umbrella.

Wants are all your non-essential purchases. Some of these non-essentials – like movie tickets, fast food, and subscription services – are easy to identify. Others are trickier to spot because they can ride the line between needs and wants. For example, your typical grocery bill can include food staples like eggs, flour, and veggies (need), snack foods or premium brands you prefer (want), household items like toilet paper and toothpaste (need), and personal care items like a fancy new shampoo (want).

By using 50/30/20, you’ll quickly realize that many of your needs are actually wants in disguise. Your basic rent is definitely a need, but if you’ve chosen to pay more for a gorgeous apartment in a prime location, then some of that payment should be coming out of your wants category.

Savings are any expenses that go toward debt repayment (beyond minimum payments) or savings goals. Student loan payments, retirement savings, and emergency fund savings all fit into this category.

Step 4: Compare Your Percentages To 50/30/20

Add up your spending totals in each category and calculate what percentage of your income they represent. If your totals for needs, wants, and savings already align to 50%, 30%, and 20% respectively, then congratulations – you must be magical! Realistically, your totals will be different and that’s OK, because this will indicate where you need to make adjustments.

Step 5: Make Adjustments

Every month, try to get closer and closer to the 50/30/20 limits you determined in Step 1. If you find you’re consistently overspending in a certain category, you have a few options available to you:

After a few months, the 50/30/20 budget will feel natural to you: you’ll know which purchases are in line with your budget and which ones aren’t. You’ll have a better understanding of – and therefore more control over – your spending, and as a bonus, you’ll begin to notice you’re closer to your savings goals than ever before.

Step 6: Keep At It

Some months are easier to budget than others. Don’t get discouraged if an unexpected expense or a moment of weakness throws you off your budgeting game. Keep tracking your spending and chasing that balance of 50/30/20.


Proportional budgets like 50/30/20 help you determine what your priorities are and ensure that you’re spending your money in a way that’s aligned with those priorities. Whether you stick with it or ultimately transition to another system, 50/30/20 will shape your understanding of and confidence with budgeting.
