Cost & Variance Interactive Lab

Cost variances don’t appear all at once.
Price variance and efficiency variance build up over time and shape the final result.


1. Variance Analysis Simulator

Adjust actual quantity (AQ), actual price (AP), standard quantity (SQ), and standard price (SP).
You can see with your own eyes exactly which path each variance takes to appear.

실제 데이터 (Actual)
표준 데이터 (Standard)
분석 리포트 (Total Variance)
총 원가 차이: ₩2,500 불리(U)

표준 원가(₩9,500) 대비 실제 지출액의 차이입니다.

원가 초과 발생 (집중 관리 필요)

What to watch: Price variance is a “price” problem; efficiency variance is an “input quantity” problem.
Separating them is what makes your improvement strategy clear.


2. A Framework for Interpreting Variances

🧠 Knowledge Check

Q. If the actual price (AP) drops below the standard price (SP), what happens to the price variance?
A. A favorable price variance occurs.


Cost management isn’t a numbers game — it’s a cause-decomposition game.
Once you break down the variance, the improvement points are immediately visible.
