Definition
The fixed overhead absorption rate refers to a rate calculated by dividing the budgeted fixed manufacturing overheads by the budgeted production level (such as units produced or standard hours). This rate is used to allocate fixed overheads to the cost of goods manufactured. Essentially, it’s a way to spread fixed overhead costs, like factory rent or salaried managerial wages, evenly across each unit produced.
\[ \text{Fixed Overhead Absorption Rate} = \frac{\text{Budgeted Fixed Overheads}}{\text{Budgeted Production Units or Standard Hours}} \]
Examples
-
Example 1: Units Basis
- Budgeted Fixed Overheads: $50,000
- Budgeted Production in Units: 10,000 units
\[ \text{Fixed Overhead Absorption Rate} = \frac{50,000}{10,000} = $5 , \text{per unit} \]
-
Example 2: Standard Hours Basis
- Budgeted Fixed Overheads: $60,000
- Budgeted Standard Hours: 20,000 hours
\[ \text{Fixed Overhead Absorption Rate} = \frac{60,000}{20,000} = $3 , \text{per hour} \]
Frequently Asked Questions (FAQs)
What are fixed overheads?
Fixed overheads are ongoing business expenses that do not change with the level of production, for example, rent on factory space, salaries of permanent staff, and depreciation of machinery.
Why is the fixed overhead absorption rate important?
The fixed overhead absorption rate is crucial for pricing products, budgeting, and ensuring all fixed costs are appropriately allocated to each unit of production, aiding in accurate product cost determination.
Companies typically use historical data, market trends, and sales forecasts to estimate budgeted production levels, which form the basis for calculating overhead absorption rates.
What is the relationship between the fixed overhead absorption rate and product costing?
The fixed overhead absorption rate ensures that fixed overheads are included in the total cost of the product, enabling more accurate pricing and profitability analysis.
What happens if actual production differs from budgeted production?
If actual production differs from budgeted production, over-absorption or under-absorption of fixed overheads occurs, which requires adjustment at the end of the accounting period.
Absorption Rate
The absorption rate is a broader term that refers to the process of allocating overhead costs to units of production, encompassing both fixed and variable overheads.
Variable Overhead Absorption Rate
This rate is calculated by dividing the budgeted variable overhead costs by the budgeted production units or other production measures, spreading variable overheads like utilities evenly across production.
Budgeted Overheads
This term refers to the estimated overhead costs prepared in advance of a period, serving as a basis for calculating various overhead absorption rates.
Standard Hours
Standard hours are estimated or predetermined labor hours needed to complete a unit of production or job, critical in calculating overhead absorption rates.

Accounting Basics: “Fixed Overhead Absorption Rate” Fundamentals Quiz
### How is the fixed overhead absorption rate calculated?
- [ ] By dividing variable overheads by production units.
- [x] By dividing budgeted fixed overheads by budgeted production units or standard hours.
- [ ] By adding all overheads together and dividing by units produced.
- [ ] By dividing fixed costs by direct labor costs.
> **Explanation:** The fixed overhead absorption rate is calculated by dividing the budgeted fixed overheads by the budgeted production units or standard hours.
### What type of cost are fixed manufacturing overheads?
- [ ] Variable costs
- [x] Fixed costs
- [ ] Semi-variable costs
- [ ] Direct costs
> **Explanation:** Fixed manufacturing overheads are costs that remain constant regardless of the level of production, such as rent, insurance, and salaries of permanent staff.
### Why are fixed overhead absorption rates important?
- [x] For accurate product costing and pricing
- [ ] To increase production levels
- [ ] To decrease variable costs
- [ ] To calculate direct material usage
> **Explanation:** Fixed overhead absorption rates are important for accurately allocating fixed overhead costs to products, which aids in proper pricing and profitability analysis.
### Which mechanism is used to spread fixed overheads across units of production?
- [ ] Fixed Cost Scaling
- [ ] Variable Overhead Distribution
- [x] Overhead Absorption
- [ ] Direct Allocation
> **Explanation:** The fixed overhead absorption rate is used to spread fixed overheads across units of production, ensuring each unit bears a fair share of these costs.
### What can cause over-absorption of fixed overheads?
- [ ] Actual production is less than budgeted production.
- [x] Actual production exceeds budgeted production.
- [ ] Variable costs increase.
- [ ] Direct labor rates decrease.
> **Explanation:** Over-absorption of fixed overheads occurs when actual production exceeds budgeted production, spreading the fixed overhead costs thinner than anticipated.
### Which term relates closely to the fixed overhead absorption rate?
- [ ] Direct Expense Rate
- [ ] Fixed Cost Ratio
- [x] Absorption Rate
- [ ] Activity-Based Costing
> **Explanation:** The term "Absorption Rate" relates closely as it is the broader concept under which fixed overhead absorption rates fall, encompassing also variable overheads.
### In what situation is under-absorption likely to occur?
- [ ] When direct material costs are high.
- [ ] When variable overheads increase.
- [ ] When actual production matches budgeted production.
- [x] When actual production is less than budgeted production.
> **Explanation:** Under-absorption occurs when actual production is less than budgeted production because the fixed overhead costs are spread over fewer units than anticipated.
### What key component is needed to compute the fixed overhead absorption rate?
- [ ] Actual overheads
- [ ] Direct material costs
- [x] Budgeted fixed overheads
- [ ] Variable costs
> **Explanation:** Budgeted fixed overheads are essential to compute the fixed overhead absorption rate by dividing them with the budgeted production units or standard hours.
### How does fixed overhead absorption aid in budgeting?
- [x] By providing a basis to allocate fixed costs to each unit
- [ ] By increasing direct material cost accuracy
- [ ] By reducing overall fixed costs
- [ ] By creating a flexible budget scenario
> **Explanation:** It aids in budgeting by determining a rate to allocate fixed costs accurately to each unit of production, ensuring all fixed costs are accounted for.
### Who benefits most directly from understanding fixed overhead absorption rates?
- [x] Cost accountants and management
- [ ] External auditors
- [ ] Sales personnel
- [ ] Human resources
> **Explanation:** Cost accountants and management benefit most directly as this understanding helps them in cost control, pricing decisions, and overall budgeting processes.
