Written by WithU Insights Team | September 10, 2026

This is the year you really dedicate yourself to a budget, right? But sitting down and trying to wing it is nearly impossible, and looking online for a model that works for you is overwhelming. It can all get very complicated very fast, which is why we’re taking the time to break down one of the more straightforward methods out there.

The 50/30/20 rule.

Who Needs a Budget? The Debt Situation in the U.S.

If your monthly finances are a mess, you’re definitely not alone. In 2025, a survey of Americans by the U.S. Federal Reserve found that 37% of Americans would not be able to cover an unexpected $400 with cash or savings and 45% of Americans did not have an emergency fund capable of covering three months of expenses.In statistics covering average American debt in 2024 by Consumer Affairs®, household debt in the U.S. reached $17.5 trillion in the fourth quarter of 2023.

What Is the 50/30/20 Budget Rule? And What Are the Benefits?

The 50/30/20 Rule, Explained

The goal of this rule is to give people a simple, straightforward way to think about how their money is spent and where to allocate it. It uses three categories: Needs, Wants, and Savings. The guiding principle is to use 50% of your after-tax income for your Needs, 30% for your Wants, and 20% for your Savings.

Needs

These are your must-haves, your nonnegotiables. The bills that have to be paid and purchases that have to be made in order for you to survive. So this includes things like:

  • Monthly rent or mortgage

  • Utility bills

  • Car payments

  • Medical expenses and insurance

  • Groceries

  • Gas

  • Minimum payments on credit cards

If you’re spending more than 50% on Needs, you might need to cut down on Wants or consider whether you’ve maybe categorized something as a Need that isn’t actually something you can’t live without.

Wants

These are non-essentials that you choose to invest in, like a gym membership, concert tickets, streaming subscriptions. The things that make life a little more enjoyable for yourself. This can include a lot of things, but a few more examples:

  • Supplies for hobbies

  • Non-essential travel like vacations

  • Expensive or unnecessary clothes, shoes, jewelry, etc.

  • Upgraded items like the latest smartphone when your current one works fine

  • Fancy restaurant meals

It’s important to note that there is nothing “bad” about having Wants. Sure, maybe we can live without them, but they bring value and joy to our lives all the same. The goal is to focus on your most important Wants to keep it at or under that 30% of your after-tax income.

Savings

Remember that statistic about how many Americans don’t have significant savings? That’s what this 20% is for, building up for the future. Ideally, you will have enough savings to cover 3-6 months of expenses in case you can’t work, but you also want to be saving for major financial goals and retirement.

The most straightforward way to save is by opening a savings account, but you can also do things like:

  • Opening an IRA or other kind of retirement account

  • Investing in stocks and other assets

  • Paying extra on any existing debt in order to bring down your debt load faster

Pros and Cons of the 50/30/20 Rule

No single budgeting method is going to work for absolutely everyone, so let’s look at both the pros and the cons.

In general, we’d recommend for those who are brand-new to budgeting, who need a simple, easy way to get started. And then, as you start to get more comfortable with your income and expenses, you can consider whether you need to shift to a more detailed method or budgeting app.

Ready to Start Your Own 50/30/20 Budget?

If the 50/30/20 budget rule sounds like something you want to try, there are a few steps you can take to get started. First and foremost, you should track the flow of cash in and out of your bank account for a couple of months to get a better idea of where you’re spending. Once you understand your income and expenses, you can narrow in on which ones are necessities and then slot everything into those three categories: Needs, Wants, Savings. It can help to set up automated payments and cash transfers, both for covering your Needs and ensuring you set aside the right amount of Savings.

And the most important element of every budget method out there: stay consistent. Even if you make mistakes, overspend, or have a bad month, keep at it and remember that it’s all about long-term results.
