The formula to calculate the price variance percentage (PVP) is:
\[ PVP = \frac{PV}{TP} \times 100 \]
Where:
Let's say the price variance (PV) is $200 and the average total price (TP) is $1000. Using the formula:
\[ PVP = \frac{200}{1000} \times 100 \]
We get:
\[ PVP = 20\% \]
So, the price variance percentage is 20%.
