• Side hustle income
• Investment income
• Rental income
• Child support/alimony
• Other regular income

Example Calculation:

Primary job: $5,000/month (after tax)

Total monthly income: $5,800

Step 2: List All Monthly Expenses

Fixed Expenses (same every month):

• Rent/mortgage: $1,800

Common Budgeting Mistakes

Mistake 1: Being Too Restrictive

The Problem: Creating an unrealistically tight budget that allows no flexibility leads to frustration and eventual abandonment.

The Solution:

• Build in "fun money" category
• Allow for occasional splurges
• Include miscellaneous buffer (5%)
• Make gradual spending reductions

Mistake 2: Forgetting Irregular Expenses

The Problem: Not accounting for quarterly, semi-annual, or annual expenses creates budget emergencies.

The Solution:

• List all irregular expenses
• Divide annual costs by 12
• Save monthly amount in sinking funds
• Examples: car insurance, property taxes, gifts

Mistake 3: Not Tracking Small Purchases

The Problem: Coffee, snacks, apps, and small purchases add up to hundreds per month.

The Solution:

• Track every purchase for 30 days
• Identify "spending leaks"
• Decide which small expenses to eliminate
• Build reasonable amount into budget

Mistake 4: Comparing to Others

The Problem: Trying to match friends' or social media lifestyles leads to overspending.

The Solution:

• Focus on YOUR financial goals
• Remember social media shows highlights
• Set boundaries on social spending
• Choose lower-cost social activities

Mistake 5: Not Having Emergency Buffer

The Problem: Budget has zero margin for unexpected expenses, forcing debt use.

The Solution:

• Keep buffer in savings account
