With our budgeting calculators, you can apply the popular 50/30/20 savings rule to your finances to help you achieve your savings goals.

What is the 50/30/20 Rule?

This 50/30/20 method, or 50/30/20 rule, is a popular strategy for budgeting monthly income. With this method, your money is allocated into three categories: needs, wants and savings and debt. Here’s how it works.

Needs

Your needs include costs like the following, which you must pay monthly as part of your regular expenses. Monthly rent or mortgage payments groceries, and utility bills are everyday necessities. These expenses account for 50% of your net monthly pay under the 50/30/20 rule.

Wants

Wants, also called discretionary spending, are optional costs that account for part of your monthly expenses. These costs might include things like dining out, trips to the movies or weekends away. Wants account for 30% of your monthly income after taxes under the 50/30/20 method.

Savings and Debt

The 50/30/20 method allocates 20% of your net monthly pay toward savings and debt repayment. You might use a portion of this 20% to repay credit card debt each month, some for retirement savings and the rest to grow your emergency fund.

How to Use the Budget Calculator

To use our budget calculator, you’ll first want to determine your monthly income after taxes, also called your take-home pay. This number serves as the basis for your 50/30/20 calculation, and it’s the amount you receive each month after taxes and other costs are deducted from your paychecks. Here’s a step-by-step example of how you might budget if you’re paid bi-weekly.

  1. Find net income on your paycheck.
  2. Multiply that number by two to determine your net monthly income.
  3. Input net monthly income into our calculator.
  4. Our calculator will allocate your income to needs (50%), wants (30%) and savings and debt (20%).

Breakdown of Needs

Once the calculator has allocated 50% of your budget to necessary costs, you can break down these costs even further into common categories like:

  • Housing expenses
  • Transportation expenses
  • Educational expenses
  • Food and personal expenses
  • Utility expenses

Breakdown of Wants

Your wants include discretionary spending, which aren’t essential costs but are still an important part of your budget. Our budgeting calculator will allocate 30% of your monthly net income toward needs, and you can then decide how that 30% will be allocated. Common examples of wants include:

  • Subscriptions
  • Travel
  • Meals out
  • Entertainment


Breakdown of Savings and Debt

While your expenses are important, your savings are arguably more important. This is especially true if your goal is to save more money. Our calculator will break down 20% of your monthly income after taxes into savings, but your savings goals might be different depending on your situation. You can break down this 20% into different categories that best align with your goals. Potential categories could include:

  • Emergency fund
  • Retirement savings
  • College savings
  • Debt/credit card payments


How to Create a Budget

Use our 50/30/20 budget calculator as a starting point for managing your money. This budgeting method offers some flexibility, making it suitable for many people. If you’d like to be more hands-off with budgeting, you can simply allocate 50% of your monthly pay toward essential costs, 30% toward non-essential costs and 20% toward savings and debt repayment.

You can also drill down further if you’d prefer to be hands-on and allocate funds to more specific categories. For instance, you might put half of your 50% monthly allocation toward housing expenses and a quarter toward food and personal expenses.

 

What are Some Popular Budgeting Strategies?

While the 50/30/20 budgeting method is popular, many other budgeting options are available. Each option starts with figuring out your net monthly income and monthly expenses, though actual budgeting approaches differ depending on your chosen strategy.

 Pay yourself first: With this simple budgeting method, your first contribution from your monthly paycheck goes toward savings. The remainder goes toward your bills and other expenses.

  • Zero-based budgeting: This more complicated and hands-on budgeting method involves giving each dollar from your paycheck a job each month until you have $0. While your dollars will go toward your monthly expenses, you can also allocate some of them to savings.
  • Envelope budgeting: This budgeting system is also very hands-on. You create an envelope (or spreadsheet tab) for each monthly spending category and put specific amounts into each category. Once you’ve exhausted the amount you allotted, you can’t spend any more in that category in a given month. For more helpful budgeting tips, read our article on creating a dynamic household budget.


The Bottom Line

Budgeting can give you a better understanding of your spending and serve as the foundation for growing your savings. The 50/30/20 method is a popular budgeting strategy, but it isn’t necessarily the best system for everyone. Fortunately, several approaches exist if your goal is to develop a budget.
