1. What is the 50/30/20 Budget Rule?

The 50/30/20 rule is a simple budgeting method that divides your after-tax income into three categories: 50% for needs, 30% for wants, and 20% for savings and debt repayment. This rule provides a balanced approach to managing personal finances.

2. How Does the Calculator Work?

The calculator uses the 50/30/20 formula:

Where:

• \( Income \) — Your after-tax income in £
• \( Needs \) — Essential expenses (housing, utilities, groceries, etc.)
• \( Wants \) — Non-essential spending (dining out, entertainment, etc.)
• \( Savings \) — Savings, investments, and debt repayment

Explanation: The rule provides a simple framework for balancing essential expenses, discretionary spending, and financial goals.

3. Importance of Budget Allocation
