How To Use the 50/30/20 Rule for Budgeting Your Money

What Is the 50/30/20 Rule?

The 50/30/20 rule is a percentage-based budgeting method designed to help you manage money easily and effectively. To use it, divide your monthly after-tax income into three categories: 50% for needs, 30% for wants, and 20% for saving or paying off debt.

With only three main spending categories, you can ensure you pay all your bills on time, have money to do the things you want, get out of debt, and increase your savings.

As simple as it is and as great as it sounds, the 50/30/20 rule doesn’t work for everyone. Find out if the 50/30/20 rule will work for you.

Why Use the 50/30/20 Rule to Budget Your Money?

Having only three expense categories to track with a 50/30/20 budget simplifies the budgeting process. You don’t have to be as meticulous about tracking every expense, and it isn’t as time-consuming as other budgeting methods. The simplicity makes it easier to stick to for some people.

If you spend first and then save whatever random amount you have left at the end of the month or have trouble saving any money, the 50/30/20 budgeting system could also help you increase your savings. If you’re looking for a simpler budgeting approach, this budgeting system could work well for you.

How To Budget With the 50/30/20 Rule

The 50/30/20 rule makes budgeting easier by allocating your after-tax income into three spending categories: needs, wants, and savings or debt. Here is how the 50/30/20 rule works:

50% for Needs

Needs are your essential living expenses. Your basic needs are comprised of fixed expenses, obligations you must pay, and things you need to survive. Examples of needs include:

  • Mortgage payments or rent
  • Groceries
  • Health insurance
  • Essential clothing
  • Insurance
  • Child care costs
  • Utilities
  • Auto loan payments and other transportation costs
  • Minimum debt payments

Consider needs as basic living expenses or bills you are contractually required to pay. Needs do not include discretionary spending or extras like restaurant meals, entertainment, or weekend getaways.

It can be difficult to lower your monthly expenses by spending less on needs, but it can be done. For example, you might switch to a cheaper car insurance policy, find ways to lower your housing expenses, or get a new cell phone plan.

If your needs and financial obligations exceed half of your take-home pay, it doesn’t necessarily mean that the 50/30/20 system doesn’t work for you. Decide if spending less on your wants, eliminating bad spending habits, increasing your income, or making lifestyle changes is necessary.

30% for Wants

Wants are non-essential expenses you spend money on but could live without. Things like:

  • Gym memberships
  • Streaming services like Netflix and other monthly subscriptions
  • Leisure travel
  • Starbucks
  • Hobbies
  • The latest electronic gadget
  • Other discretionary spending

Wants may make things easier, more fun, or improve your quality of life. They aren’t essential to survival, however.

20% for Savings and Debt Repayment

Devote 20% of your net income to savings. This includes investments, your emergency fund, and retirement savings.

The savings category also includes paying off debt. Minimum payments go in the needs category, but any extra payments you make as part of your debt payoff strategy lower your balance and reduce the interest you pay, so they count as savings.

One of the biggest benefits of using the 50/30/20 rule and other percentage-based budgeting techniques is that saving money is built in. By dedicating a fixed percentage of your earnings to savings, you can rest assured knowing that money is going toward your future financial goals every month. That could represent a stark change if you’re using another budgeting system or your monthly savings are an afterthought.

You can further divide the 20% savings bucket into short-term savings, long-term financial goals, and getting out of debt. You might prioritize:

  • Paying off your credit card debt
  • Emergency savings
  • Saving for a down payment on a house
  • Building your college savings fund
  • Retiring your student loan debt
  • Saving for retirement

You could put more of the 20% toward your primary savings goal.

50/30/20 Rule Example

Here is a 50/30/20 budget example:

Suppose you are a single person who contributes to an employer-sponsored retirement plan. After payroll deductions for health insurance, a 401k contribution of $184 per month, Social Security, Medicare, and state and federal taxes, your net monthly income is $2,400.

Based on the 50/30/20 rule, your personal budget would look like this:

  1. Needs: $1,200 ($2,400 x 0.50) for needs.
  2. Wants: $720 ($2,400 x 0.30) put toward nonessential spending.
  3. Savings and Debt Reduction: $480 ($2,400 x 0.20) goes to savings and paying off debt. Since $184 in retirement contributions were already made, the remaining $296 ($480 – $184) can be used to get out of debt, fund retirement accounts, make additional savings contributions, or other future goals.

Now that the rule has been applied to your post-tax income, the next step is to create your spending plan using these numbers.

Gather your bank statements, utility bills, and all other bills, then review your spending.

If your expenses don’t align with the target percentages and you want to stick with a percentage-based budget, you can:

  • Adjust the percentages
  • Cut expenses
  • Increase your income
  • Implement some combination of the above

For example, you might:

  • Bump needs up to 60% and lower wants to 20%
  • Take on a second job or side hustle
  • Negotiate lower interest rates with creditors
  • Use public transportation more
  • Find ways to reduce your housing costs

You don’t have to treat 50/30/20 as a hard-and-fast rule that can’t be modified to better suit your financial situation and goals.
