Calculate Predetermined Overhead Rate

Introduction

Understanding the predetermined overhead rate is crucial for businesses aiming to accurately allocate manufacturing overhead costs to products. This rate allows companies to estimate the overhead costs associated with production, which is essential for setting the right prices and maintaining profitability. The predetermined overhead rate is calculated by dividing the estimated manufacturing overhead costs by an allocation base, such as direct labor hours or machine hours. This approach helps in assigning overhead costs to products more precisely compared to actual overhead costs, which can fluctuate.

Efficiently managing these calculations can be challenging without the right tools. In the following sections, we will explore how Sourcetable simplifies the calculation of predetermined overhead rate and enhances your business analytics through its AI-powered spreadsheet assistant.

How is Predetermined Overhead Rate Calculated?

To effectively calculate the predetermined overhead rate (POR), understand the primary components involved in its calculation. This rate is crucial for businesses to allocate overhead costs accurately and predict expenses for upcoming projects.

Estimate Manufacturing Overhead Costs

Begin by estimating the total manufacturing overhead costs. This includes all indirect expenses related to production, such as utilities, depreciation, and salaries of support staff.

Identify the Allocation Base

Select an appropriate allocation base, also referred to as the activity driver. Common bases include machine hours, direct labor hours, or direct materials cost, which help in distributing overhead costs more accurately based on actual usage or consumption.

Calculate the Predetermined Overhead Rate

Divide the estimated manufacturing overhead costs by the chosen allocation base using the formula POR = Estimated Overhead Costs / Allocation Base. This calculation yields the POR, which is typically expressed as a rate per unit of the allocation base.

Examples of Calculation

For instance, if a company estimates overhead costs at $15,000 and plans to utilize 25,000 machine hours, the calculation would be $15,000 / 25,000 leading to a POR of $0.60 per machine hour. Similarly, other examples might use different bases such as direct labor hours or direct materials costs, adjusting the formula accordingly.

Understanding and implementing this calculation allows companies to monitor and control their production expenses adeptly, ensuring more accurate job costing and financial planning.

How to Calculate the Predetermined Overhead Rate

Understanding Predetermined Overhead Rate

Predetermined overhead rate (POR) simplifies the allocation of manufacturing overhead costs to products or job orders. This rate is crucial for accurate product costing and financial planning.

Steps to Calculate Predetermined Overhead Rate

Calculating the POR involves three main steps. First, estimate the total manufacturing overhead costs for a period. Next, determine the allocation base, also known as the activity driver, which could be machine hours, labor hours, or any cost driver relevant to the business operations. Finally, apply the formula estimated overhead / allocation base to find the POR.

Example of Calculating Predetermined Overhead Rate

For instance, if a company estimates an overhead of $15,000 and expects to use 25,000 machine hours in a year, the POR would be calculated as follows: 15,000 / 25,000 = 0.60 per machine hour. This rate helps allocate overhead costs accurately across products and services.

Importance of Accurate Calculation

Accurate calculation of the predetermined overhead rate enables businesses to price their products appropriately, manage budgets effectively, and close financial books faster. It also facilitates the monitoring of actual versus estimated costs to refine future overhead estimations.

Calculating Predetermined Overhead Rate

Predetermined overhead rate is critical for accurate product costing and financial planning. This rate is calculated by dividing estimated manufacturing overhead costs by an allocation base. This section covers practical examples to demonstrate how to calculate this rate using common bases such as direct labor hours, machine hours, and direct labor cost.

Example 1: Direct Labor Hours

In a factory where estimated overhead costs are $120,000 and total direct labor hours are expected to be 20,000 hours, the predetermined overhead rate would be calculated as follows: Overhead Rate = Estimated Overhead Costs / Total Direct Labor Hours = $120,000 / 20,000 hours = $6 per labor hour.

Example 2: Machine Hours

Consider a manufacturing plant with overhead costs estimated at $200,000 and total machine hours are 40,000 hours. To find the overhead rate: Overhead Rate = Estimated Overhead Costs / Total Machine Hours = $200,000 / 40,000 hours = $5 per machine hour.

Example 3: Direct Labor Cost

For a business with estimated overhead expenses of $150,000 and direct labor costs projected at $300,000, the overhead rate is calculated by: Overhead Rate = Estimated Overhead Costs / Total Direct Labor Cost = $150,000 / $300,000 = 50% of direct labor cost.

By understanding and applying these methods, businesses can allocate their manufacturing overhead more precisely, leading to more accurate product costing and financial planning.
