Understanding Rate and Volume Variance

In financial analysis, variance analysis is a critical tool used by management to compare actual results against budgeted figures. When analyzing differences in revenue or costs, we often split the "Total Variance" into two primary components: Rate Variance and Volume Variance.

1. Rate Variance (Price Variance)

Rate variance measures the impact of the difference between the actual price or rate paid (or received) and the budgeted price. It focuses purely on the "price" element by holding the actual volume constant.

Formula: (Actual Rate – Budgeted Rate) × Actual Volume

2. Volume Variance (Quantity Variance)

Volume variance measures the impact of selling or producing a different quantity than originally planned. It isolates the "quantity" element by using the budgeted rate as a baseline.

Formula: (Actual Volume – Budgeted Volume) × Budgeted Rate

Practical Example

Imagine a company budgets to sell 1,000 widgets at $50 each (Budgeted Revenue: $50,000). At the end of the month, they actually sold 1,200 widgets at $55 each (Actual Revenue: $66,000).

• Total Variance: $66,000 – $50,000 = $16,000 (Favorable)
• Rate Variance: ($55 – $50) × 1,200 = $6,000 (Favorable – we sold them for $5 more than expected)
• Volume Variance: (1,200 – 1,000) × $50 = $10,000 (Favorable – we sold 200 more units than expected)

In this case, the $16,000 surplus can be explained by a $6,000 increase due to better pricing and a $10,000 increase due to higher demand.

Why This Calculation Matters

By separating these two variances, a business can determine if its strategy is working. If Volume Variance is high but Rate Variance is negative, it might mean the company is driving sales by discounting too heavily. Conversely, a high positive Rate Variance with a negative Volume Variance might suggest that price increases are driving away customers.
