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.

How do I calculate the 50/30/20 rule?

Calculating the 50/30/20 rule is straightforward and involves three simple steps:

  1. Determine Your Net Income
    • What is net income? This is your take-home pay after taxes and any automatic deductions (like health insurance or retirement contributions) have been subtracted from your gross income.
  2. Divide Your Income According to the Rule

    • Wants (30%): Allocate 30% to non-essential, lifestyle-related expenses. These include dining out, entertainment, vacations, hobbies, and other discretionary spending.
    • Savings and Debt Repayment (20%): Allocate 20% to savings, investments, and paying down debt beyond minimum payments. This includes emergency funds, retirement savings, and extra debt payments.
  3. Apply the Calculation
    • Formula:
      • Needs: Net Income×0.50Net Income×0.50
      • Example:
        • Net Income: $4,500/month
        • Needs: $4,500 × 0.50 = $2,250
        • Wants: $4,500 × 0.30 = $1,350
