30/30/30 規則計算器

The 30/30/30 Rule Calculator is a simple budgeting guideline that helps individuals manage their finances effectively. This rule suggests dividing your after-tax income into three equal parts: 30% for essential needs, 30% for financial goals, and 30% for lifestyle choices, with the remaining 10% as a flexibility buffer.

Historical Background

This rule is derived from the famous 50/30/20 budgeting rule, which allocates income to needs, wants, and savings. The 30/30/30 rule adopts a more balanced approach, particularly suitable for individuals who prioritize financial stability while desiring a moderate lifestyle.

Calculation Formula

According to the 30/30/30 rule allocation:

• Essential Needs = After-tax Income × 30%
• Financial Goals = After-tax Income × 30%
• Lifestyle Choices = After-tax Income × 30%
• Remaining = After-tax Income - (Essential Needs + Financial Goals + Lifestyle Choices)

Example Calculation

For an individual with an after-tax income of $4,000:

• Essential Needs: $4,000 × 30% = $1,200
• Financial Goals: $4,000 × 30% = $1,200
• Lifestyle Choices: $4,000 × 30% = $1,200
• Remaining: $4,000 - ($1,200 + $1,200 + $1,200) = $400

Importance and Usage

1. Balanced Budgeting: It ensures a balanced approach between comfortable living, savings, and enjoying life.

3. Adaptable Framework: Suitable for different income levels and financial situations.
