Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Job Cost Variance to answer this question: compare actual job cost with estimated cost and calculate the effect on expected gross profit?

Age 15Explain it to a 15-year-oldConnect it to the formula
A positive cost variance is an overrun. Review materials, labour, subcontractor and overhead components to identify the cause. The rule is Job cost variance = actual job cost − estimated job cost. Its input values are Contract revenue, Estimated job cost, Actual job cost, Approved change-order revenue, and the main result is Job cost variance. Try changing one number and watch what happens to Job cost variance.
CollegeExplain it at college levelState the model precisely
This calculator evaluates one accounting relationship within a consistent entity, currency, reporting period and recognition policy. The implemented relation is Job cost variance = actual job cost − estimated job cost, evaluated from Contract revenue, Estimated job cost, Actual job cost, Approved change-order revenue to produce Job cost variance. A positive cost variance is an overrun. Review materials, labour, subcontractor and overhead components to identify the cause. Recognition, measurement, tax, consolidation, foreign-currency and disclosure rules may require adjustments under the accounting framework that applies to the entity.
What this accounting tool does
