Calculator Form
Use expense mode for spending budgets. Use income mode for revenue or side income targets.
Formula Used
This calculator compares your planned amount with your actual amount for each category.
Variance = Actual - Budget
Positive variance means actual exceeded budget. Negative variance means actual stayed below budget.
Variance Percentage = ((Actual - Budget) / Budget) × 100
When the budget is zero, the percentage is not shown.
Absolute Variance = |Actual - Budget|
For expense budgets, lower actual spending is favorable. For income budgets, higher actual income is favorable.

Frequently Asked Questions
1. What does variance mean in budgeting?
Variance is the difference between what you planned and what actually happened. It helps you see overspending, underspending, or missed income targets quickly and clearly.
2. Why is a negative variance sometimes good?
In expense mode, a negative variance means you spent less than budgeted. That is usually favorable because you stayed below your planned spending level.
3. Why is a positive variance sometimes good?
In income mode, a positive variance means actual income exceeded the target. That is favorable because you earned more than planned.
4. What if my budget amount is zero?
The calculator still shows the money variance. The percentage is marked as not available because dividing by zero would make the percentage misleading.
5. Can I use this for monthly and yearly budgets?
Yes. Use any period label you want, including weekly, monthly, quarterly, or yearly. The math stays the same for every time range.
6. What does absolute variance show?
Absolute variance ignores the sign and shows the gap size only. It is useful when you want to measure deviation magnitude without focusing on direction.
7. Why compare categories individually?
Category-level review shows where budget pressure comes from. You can identify problem areas, protect stronger categories, and adjust future targets more accurately.
8. When should I download the report?
Download after each review period if you want records for meetings, audits, or personal tracking. Regular reports make trend analysis much easier later.
