How the calculation works
Variance = actual − budget. Variance % = (actual − budget) ÷ budget × 100.
Use the result as a planning aid. Check the source records and the assumptions before making financial decisions.
Compare planned and actual amounts
The variance tool compares budgeted and actual figures by category. Keep the same period and basis for both.
Explain the difference
A positive difference is not always favorable: more revenue and more expense have different meanings. A zero budget also needs special treatment because percentage variance cannot be calculated by dividing by zero.
