A PRACTICAL GUIDE

How to use the Budget Variance Analyzer.

State the sign convention when describing budget variance. Higher revenue and higher expense have different meanings, even when both produce a positive actual-minus-budget number.

Make the workflow fit your task.

Align budget and actual figures to the same period, category and accounting basis. State the subtraction convention, calculate absolute and percentage differences, and distinguish favorable direction for revenue and expense. Use supplied driver notes without inventing causes.

Decisions and troubleshooting.

How should a percentage variance be reported when the budget is zero?

The ordinary percentage calculation is undefined. Show the absolute difference and explain the zero baseline.

Why is a positive variance favorable in one row and unfavorable in another?

Higher revenue and higher expense have different implications. Label the measure and interpretation instead of relying on the sign alone.

Try it with your own source.
