Budget spent and remaining calculator
How to calculate it
Divide category spending by total budget and multiply the quotient by 100. The total must represent the complete observed set.
- Insert the values in the formula, perform the division first, and round only the final answer.
- The answer says how many units out of every 100 the part represents. 100% equals the total; more than 100% means the part exceeds the reference.
Applied example
When category spending is 500 € out of 2000 €, it represents 25%.
Divide category spending by total budget and multiply the quotient by 100. The total must represent the complete observed set. The answer says how many units out of every 100 the part represents. 100% equals the total; more than 100% means the part exceeds the reference.
Practical use
See how much of a budget a category uses or how spending changed.
For budgets and expenses, use “total budget” as the reference. It must represent the full set or the starting point of the comparison.
Checks that matter
- Use the approved budget as the base and avoid double-counting subtotals.
- Do not swap the part and total; reversing them changes the meaning of the result.
- Keep full precision during the calculation and round only the final answer to match the accuracy of the source data.
