How to Calculate Expense to Income Ratio

To calculate your expense-to-income ratio, divide your total monthly expenses by your gross monthly income, then multiply by 100 to get a percentage.


For example, if your total monthly expenses are $2,500 and your gross monthly income is $5,000, your calculation would be: ($2,500 ÷ $5,000) × 100 = 50%. This means 50% of your income goes toward expenses By calculating this ratio, you can quickly evaluate how much of your income is going toward bills, living costs, and other expenses.

Expense to Income Ratio Formula

The basic formula used to calculate the expense to income ratio is:

Expense to Income Ratio = (Total Expenses ÷ Total Income) × 100

This formula converts the relationship between expenses and income into a percentage. A lower percentage means you are spending less of your income, while a higher percentage indicates that most of your income is going toward expenses.

Step-by-Step Calculation

  1. Determine your total income for a specific period (weekly, monthly, or yearly).
  2. Add all expenses for the same period.
  3. Divide the total expenses by the total income.
  4. Multiply the result by 100 to convert it into a percentage.

Example 1: Weekly Expense to Income Ratio

Suppose your weekly income is $900 and your weekly expenses are $360.

= (360 ÷ 900) × 100

= 0.40 × 100 = 40%

This means you spend 40% of your weekly income on expenses and the remaining 60% can be used for savings or other financial goals.

Example 2: Monthly Expense to Income Ratio

Assume your monthly income is $4,000 and your monthly expenses total $2,600.

= (2600 ÷ 4000) × 100

Expense to Income Ratio = 0.65 × 100 = 65%

This indicates that 65% of your monthly income is used for expenses.

Example 3: Yearly Expense to Income Ratio

If your yearly income is $60,000 and your yearly expenses are $42,000, the calculation would be:

= (42000 ÷ 60000) × 100

Expense to Income Ratio = 0.70 × 100 = 70%

This means 70% of your yearly income goes toward expenses.

Understanding this ratio helps you control spending, improve budgeting, and maintain a healthier financial balance.
