The calculator pre-loads 10 standard budget categories — 2 income rows and 8 expense rows. Enter the amounts for each category that applies to your situation, and delete the rows you don't need with the × button. Add new rows for any income or expense category not already listed. Choose Monthly to see your monthly balance and projected annual net, or Annual to enter and view yearly figures. Click Calculate to see your total income, total expenses, net balance and savings rate instantly.
Total Income is the sum of all rows marked as Income. Total Expenses is the sum of all Expense rows. Net Balance is income minus expenses — a positive figure means you are living within your means; a negative figure means you are spending more than you earn and need to cut costs or increase income. Savings Rate shows what percentage of your income you are saving. In Monthly mode, the Projected Annual Net multiplies your monthly net balance by 12 to show what you are on track to save or overspend in a year.
One of the most widely used budgeting frameworks divides your after-tax income into three categories:
The 50/30/20 rule is a starting point, not a rigid rule. High cost-of-living cities may push needs above 50%. High earners often target 30–40%+ savings rates. The key is knowing your numbers — which is exactly what this calculator gives you.
This calculator is provided for general informational and educational purposes only and does not constitute financial, tax, investment or legal advice. It uses simple income-minus-expense arithmetic combined with the widely-used 50/30/20 budgeting framework, but actual figures depend on your lender, local regulations, fees and current market conditions, and may differ from your final terms.
Before making a financial decision, verify your numbers with a licensed financial advisor, accountant, mortgage broker, or your relevant national tax authority.
