What is the formula to find the average variable cost?
The formula for calculating average total cost is:
- (Total fixed costs + total variable costs) / number of units produced = average total cost.
- (Total fixed costs + total variable costs)
- New cost – old cost = change in cost.
- New quantity – old quantity = change in quantity.

How to calculate variable overhead efficiency variance?
Variable overhead efficiency variance is essentially an accounting measure that is calculated by multiplying the difference between the actual and budgeted hours worked with the standard variable overhead rate per hour. The formula for calculating the variable overhead efficiency variance is:
How do you calculate VOH efficiency variance?
The formula for this variance is:(standard hours allowed for production – actual hours taken) × standard overhead absorption rate per hour (fixed or variable). (standard hours allowed for production – actual hours taken) × standard overhead absorption rate per hour (fixed or variable).
How do you calculate variance cost?
The formula for cost variance is:Cost variance = budgeted cost of work performed (BCWP) - actual cost of work performed (ACWP)Cost variance = earned value - actual cost.Cost variance % = (earned value - actual cost) / earned value.
How is cost variance analysis calculated?
Cost Variance can be calculated using the following formulas:Cost Variance (CV) = Earned Value (EV) – Actual Cost (AC)Cost Variance (CV) = BCWP – ACWP.
What is VOH cost?
Variable overhead are the costs of operating a firm that fluctuate with the level of business or manufacturing activity. As production output increases or decreases, variable overhead moves in tandem.
What is the cost variance?
Cost variance (CV), also known as budget variance, is the difference between the actual cost and the budgeted cost, or what you expected to spend versus what you actually spent.
What is the formula of material cost variance?
The formula for this variance is:(standard price per unit of material × actual units of material consumed) – actual material cost. (standard price per unit of material × actual units of material consumed) – actual material cost.
How do you calculate SV in project management?
To calculate SV, subtract your project's planned value (PV) from its earned value (EV): SV = EV – PV. You will also need to know the value of your project's planned budget at completion (BAC). If your SV is positive, your project is ahead of schedule.
What is cost variance percentage?
Cost Variance Percentage (CV%) = Cost Variance (CV) / Earned Value (EV) A cost variance percentage is the percentage over or under budget for a project is. This is calculated by dividing cost variance from earned value.
How is EAC calculated?
EAC = AC + (BAC - EV)/SPI * CPI In this case, we can use the EAC = AC + (BAC - EV) formula because we expect that the remaining budget is accurate but must account for the previous performance issues. Essentially, the EAC increases by the amount the actual cost exceeded the initial budget.
What is Clean's variable overhead spending variance?
The variable overhead spending variance is the difference between the actual and budgeted rates of spending on variable overhead. The variance is used to focus attention on those overhead costs that vary from expectations. The formula is: Actual hours worked x (Actual overhead rate - standard overhead rate)
How do you calculate material usage variance?
The formula for calculating the material usage variance is: MUV = (Standard Quantity – Actual Quantity) x Standard Price.
Illustration - Problem
A factory was budgeted to produce 2,000 units of output @ one unit per 10 hours productive time working for 25 days. 40,000 for variable overhead cost and 80,000 for fixed overhead cost were budgeted to be incurred during that period.
Constituents of Variable Overhead Cost Variance
The variable overhead cost variance is a synthesis of three variances as Variable Overhead Absorption Variance, Variable Overhead Efficiency Variance and Variable Overhead Expenditure Variance.
Formulae using Inter-relationships among Variances
The interrelationships between variances would also be useful in verifying whether our calculations are correct or not.
What is VOH variance?
VOH Exp. Variance = AVOH – SVOH for actual hours worked. VOH efficiency variance arises when the actual output produced differs from the standard output for actual hours worked. It is a measure of extra overhead (for saving) incurred solely because of the efficiency shown during the actual hours worked.
What is calendar variance?
Calendar variance = BFOH – SFOH for revised budgeted hours. Revised budgeted hours are equivalent to the standard hours for actual working days. If BFOH is greater than the SFOH, the variance is adverse, and vice versa.
What is cost variance?
The cost variance is one of the fundamental measures of the variance analysis which is part of the earned value management method introduced in PMI’s Project Management Body of Knowledge (source: PMBOK ®, 6 th ed., ch. 7.4.2.2 Data Analysis, p. 261-264).
Is EVA accurate?
Some argue that is an element of the earned value analysis (EVA) as well. However, this is not exactly accurate – EVA is rather the technique where the input data (i.e. the cost and value indicators) for the calculation of cost and schedule variances are determined. There are three types of cost variances:
What is the Variable Overhead Spending Variance?
The variable overhead spending variance is the difference between the actual and budgeted rates of spending on variable overhead. The variance is used to focus attention on those overhead costs that vary from expectations. The formula is:
Example of the Variable Overhead Spending Variance
The cost accounting staff of Hodgson Industrial Design calculates, based on historical and projected cost patterns, that the company should experience a variable overhead rate of $20 per labor hour worked, and builds this figure into the budget. In April, the actual variable overhead rate turns out to be $22 per labor hour.
Analysis
As the name suggests, variable overhead efficiency variance measure the efficiency of production department in converting inputs to outputs. Variable overhead efficiency variance is positive when standard hours allowed exceed actual hours.
Example
Calculate the variable overhead efficiency variance using the following figures:
Why do manufacturers need to include variable overhead expenses?
Manufacturers must include variable overhead expenses to calculate the total cost of production at current levels, as well as the total overhead required to increase manufacturing output in the future . The calculations can then be applied to determine the minimum price levels for products to ensure profitability .
What is variable overhead?
Variable overhead is a term used to describe the fluctuating manufacturing costs associated with operating businesses. As production output increases or decreases, variable overhead expenses move in kind.
Is extra hours paid for production a variable cost?
Also, any extra hours paid for production increases would be a variable cost. For example, the cost of utilities for the equipment—electric power, gas, and water—tend to fluctuate depending on production output, the rollout of new products, manufacturing cycles for existing products, and seasonal patterns.
Does increasing production increase overhead?
Although increasing production usually increases the total cost of variable overhead, efficiencies can occur as more products are produced. Also, price discounts on larger orders of raw materials—due to the ramp-up in production—can lower the direct cost per unit.
Is overhead variable or fixed?
There are two types of overhead costs, fixed and variable. Typically, the overhead doesn't fluctuate with increases in production of a product—which is why it's considered a fixed cost. Examples of fixed costs include: Mortgage or rent for the buildings such as the corporate office.
