Budget & Financial Calculator

Most people know roughly what they earn and spend, but rarely see both numbers together with a clear gap between them. Enter your income sources and monthly expenses by category, and the tool shows your surplus or deficit, a health score for your budget, and a projection of where your finances are heading over the next few years.

What This Tool Does

The calculator breaks your finances into categories: housing, transportation, food, healthcare, debt, savings, and miscellaneous. Each one shows what percentage of your income it takes up alongside a recommended benchmark, so you can spot what is out of line. A health score gives you an overall read on your budget, and a projection table shows how your income, expenses, and cumulative savings change year by year based on the growth rates you enter.

Inputs and Outputs

Provide the following inputs to get your estimates:

• Monthly income from all sources: salary, secondary jobs, investments, and other income
• Monthly expenses across seven categories with individual line items for each
• Projection years, expected income growth rate, and expected expense growth rate
• Preferred currency (USD, EUR, GBP, or INR), auto-detected from your location

The calculator outputs:

• Total monthly income and total monthly expenses
• Monthly surplus or deficit
• Budget health score out of 100
• Per-category spending as a percentage of income, with benchmark warnings
• Visual breakdown of expense distribution across categories
• Year-by-year projection of income, expenses, annual balance, and cumulative savings
• CSV export of the projection table

Common Use Cases

• Monthly Budget Reset: At the start of each month, enter your expected income and planned expenses to check you are not spending more than you earn before the month begins.
• Identifying Overspending Categories: Run the calculator with last month's actual numbers to see which categories are eating the most of your income and where you have the most room to cut back.
• Planning a Savings Goal: Adjust your expense inputs until your savings category hits the percentage you need, then use the projection table to see how long it takes to reach a target amount at that rate.
• Evaluating a Life Change: Changing jobs, moving cities, or taking on new debt? Update the relevant inputs to see how it shifts your monthly balance and where you stand five or ten years out.

What to Keep in Mind

The income fields expect income before taxes and deductions. If your take-home pay is significantly lower than your gross salary, enter your actual net income to get an accurate surplus or deficit figure. Expense inputs are fixed monthly estimates. Variable costs like irregular medical bills or seasonal spending will not be reflected unless you average them out first. The future projection assumes constant growth rates, so treat the results as a planning guide rather than a precise forecast.
