1. What is the 70/20/10 Budget Calculator?

Definition: The 70/20/10 Budget Calculator helps you allocate your after-tax income into three categories: 70% for essential expenses, 20% for savings or debt repayment, and 10% for lifestyle or discretionary spending. It offers a simple framework for managing personal finances in high cost-of-living environments.

Purpose: This tool assists individuals in balancing essential expenses, financial goals, and personal enjoyment, promoting financial stability and flexibility for any income level.

2. How Does the Calculator Work?

The calculator uses the following formulas:

\( E = I \times 0.70 \)

\( S = I \times 0.20 \)

\( L = I \times 0.10 \)

Where:

• \( I \): Monthly after-tax income (annual income ÷ 12 if annual);
• \( E \): Essential expenses (rent, utilities, groceries);
• \( S \): Savings or debt repayment (emergency fund, retirement, loan payments);
• \( L \): Lifestyle/discretionary spending (dining out, entertainment).

Steps:

• Enter your after-tax income and select frequency (monthly or annual).
• The calculator converts annual income to monthly if needed.
• It computes 70% for essentials, 20% for savings/debt, and 10% for lifestyle.
• Results are displayed in currency format with two decimal places.
