                                                            3200×30/100=960

            

This means you would have $960 for discretionary spending, such as dining out, entertainment, and hobbies.

  • 20% for Savings and Debt Repayment:

                                                3200×20/100=640

What Are Some Other Budgeting Methods?

The 50/30/20 rule is one budgeting strategy, but it’s not the only option you have. Here are some other budgeting methods to consider.

Zero-Based Budgeting

This popular budgeting method involves assigning a “job” to every dollar you make. That means you take your monthly take-home income and start allocating funds to your various expenses or savings, until you reach $0. 

This method is more hands-on, requiring you to think about each of your monthly expenses and the purpose of each dollar you make. You can choose to manually calculate where your funds will go, or you can use a budgeting app based on the zero-based budgeting method.

Envelope Budgeting

Envelope budgeting, sometimes called cash stuffing, could be an appealing option if your income is primarily in cash or if you prefer a visual budgeting method. This process involves dividing your income into physical envelopes, where each envelope represents a separate category. For example, you might have a “groceries” envelope and an “entertainment” envelope. You then fill each envelope with the specific amount of cash you want to budget for that category. 

As you spend money, you can see the cash decreasing in your envelopes. For many people, this is an effective way to see where their money is going and avoid overspending. 

If you want to try envelope budgeting but don’t rely on cash, you can find budgeting apps that use this method by attributing funds to virtual envelopes.

Pay-Yourself-First Budgeting

Pay-yourself-first budgeting, also called reverse budgeting, is a solid option if your priority is to save more money. This method is simple: A portion of each of your paychecks—often 10% to 20%—is deposited into your savings, and you have the remainder to spend as you need.

This strategy ensures that you save each month and also helps you avoid overspending. If you’re in a position to set aside money from each of your paychecks, you can try this method to help your savings grow.
