What this calculator tells you
This calculator adds your common monthly expenses, subtracts them from your monthly income, and shows the percentage of income used by those expenses.
Simple example
If your monthly income is $3,500 and your listed expenses total $2,900, you would have $600 left over. Your expenses would use 82.9% of your income.
How to use your result
Use the result as a quick starting point. If the number feels tight, review flexible categories like groceries, subscriptions, and other expenses before making bigger changes.
