The Purchase Price Variance Formula is a useful tool for businesses to aid in their budgeting and cost analysis. This formula provides companies with an easier way to measure the impact of changes in purchase prices on their inventory costs. It divides the difference between the amount spent on purchasing goods and the amount expected to be spent into two parts: purchase price variance (PPV) and purchase price usage variance (PUUV). PPV measures the actual change in the cost of purchased goods while PUUV reflects changes in the quantity and quality of goods purchased. By understanding both components, businesses can make informed decisions on how to allocate resources and control costs.
