Expense to Income Ratio Calculator


About Expense to Income Ratio Calculator (Formula)

The Expense to Income Ratio (EIR) calculator is a financial tool used to determine the percentage of income that is being spent on expenses. It helps individuals or businesses assess their financial health and understand how much of their income is being used to cover expenses. The EIR is calculated using the following formula:

EIR = (Total Expenses / Total Income) * 100


  • EIR represents the Expense to Income Ratio, expressed as a percentage.
  • Total Expenses refers to the sum of all expenses incurred over a specific period, such as a month or a year.
  • Total Income represents the total earnings or income generated during the same period.

To calculate the EIR, divide the Total Expenses by the Total Income to determine the proportion of income spent on expenses. Multiply this ratio by 100 to express it as a percentage.

For example, let’s say your total expenses for a month amount to $2,000, and your total income for the same period is $5,000. Using the EIR formula:

EIR = ($2,000 / $5,000) * 100 EIR = 0.4 * 100 EIR = 40%

In this case, the Expense to Income Ratio would be 40%, indicating that 40% of your monthly income is allocated towards expenses.

The EIR provides a useful measure to evaluate your spending habits and financial stability. A lower ratio indicates that a smaller portion of your income is being spent on expenses, which generally implies better financial health and higher savings. Conversely, a higher ratio suggests a larger portion of income is used for expenses, which may signify potential financial strain or a need for expense management.
