Breaking Down the 50/30/20 Rule in Detail

Needs are expenses you must pay to survive and function day-to-day. Examples include:

Example:

If your monthly income is ₦300,000, then:

• ₦150,000 (50%) goes toward needs

2. The 30% Rule: Wants (Lifestyle Choices)

• Eating out

• Subscriptions (Netflix, Spotify)

• Shopping

• Travel

• Entertainment

• Upgraded phone plans

Example:

From a ₦300,000 income:

• ₦90,000 (30%) is allocated to wants

3. The 20% Rule: Savings & Debt Repayment

This category focuses on your Long-term financial stability. It includes:

• Emergency fund

• Retirement savings

• Investments

• Extra debt payments (beyond minimums)

• Business capital

Example:

• ₦60,000 (20%) goes into savings or investments
