Formula Explained

The spending money is calculated using this formula:

Spending Money = (Income - Fixed Expenses - Variable Expenses) × (1 - Savings Percentage)

Where:

Income - Your total monthly income
Fixed Expenses - Regular monthly costs (rent, utilities, loans)
Variable Expenses - Flexible monthly costs (groceries, entertainment)
Savings Percentage - The portion of income you want to save (e.g., 20% = 0.20)

This formula helps you understand how much of your income is available for spending after accounting for essential expenses and savings.

Worked Example

Let's say you have:

Monthly income: $3,000
Fixed expenses: $1,200 (rent, utilities, loans)
Variable expenses: $600 (groceries, entertainment)
Savings goal: 20% of income

Using the formula:

Spending Money = ($3,000 - $1,200 - $600) × (1 - 0.20) = $1,200 × 0.80 = $960

This means you can allocate $960 per month to spending, with $600 going to savings.
