Understanding Fixed, Variable, and Period Costs
What are Period Costs?
Period costs are expenses that are charged to a specific period, usually the period in which they are incurred. Unlike product costs (like direct materials or labor tied directly to making a product), period costs are not included in the cost of inventory. Examples often include selling expenses (like marketing, sales salaries) and administrative expenses (like office rent, executive salaries).
Fixed vs. Variable Costs
- Fixed Costs: These costs remain constant in total regardless of changes in the level of activity (like production volume or sales) within a relevant range. Examples include rent, salaries (not tied to production), insurance, property taxes, depreciation (straight-line).
- Variable Costs: These costs change in total in direct proportion to changes in the level of activity. Examples include direct materials, direct labor (tied to production), sales commissions, shipping costs, variable utilities.
The Simple Formula
The Total Period Cost is simply the sum of all costs classified as period costs for that period. In a simplified model focusing on just fixed and variable period costs:
Total Period Cost = Total Fixed Costs + Total Variable Costs
Examples of Calculating Total Period Cost
Click on an example to see the calculation:
Example 1: Small Business Office Costs
Scenario: A small business incurs costs for its office.
Known Values: Fixed Costs (Rent, Internet, Salaries) = $2,500, Variable Costs (Office Supplies based on usage, Printing) = $300.
Calculation: Total Period Cost = $2,500 (Fixed) + $300 (Variable)
Result: Total Period Cost = $2,800.
Example 2: Freelancer Monthly Expenses
Scenario: A freelancer tracks monthly business expenses.
Known Values: Fixed Costs (Software Subscriptions, Co-working Space Fee) = $450, Variable Costs (Project-specific materials, Travel for meetings) = $150.
Calculation: Total Period Cost = $450 (Fixed) + $150 (Variable)
Result: Total Period Cost = $600.
Example 3: Restaurant Monthly Overheads
Scenario: Calculating administrative and selling costs for a restaurant's month.
Known Values: Fixed Costs (Manager Salary, Insurance) = $4,000, Variable Costs (Marketing Spend, Some Utilities fluctuation) = $800.
Calculation: Total Period Cost = $4,000 (Fixed) + $800 (Variable)
Result: Total Period Cost = $4,800.
Example 4: Software Company Quarterly Expenses
Scenario: A software company calculates its non-development related expenses for a quarter.
Known Values: Fixed Costs (Office Rent, Administrative Salaries) = $15,000, Variable Costs (Sales Commissions, Travel Expenses) = $7,000.
Calculation: Total Period Cost = $15,000 (Fixed) + $7,000 (Variable)
Result: Total Period Cost = $22,000.
Example 5: Retail Store Monthly Operation Costs
Scenario: Calculating the period costs for a retail store.
Known Values: Fixed Costs (Store Lease, Base Staff Salaries) = $8,000, Variable Costs (Advertising, Shopping Bag costs based on sales) = $1,500.
Calculation: Total Period Cost = $8,000 (Fixed) + $1,500 (Variable)
Result: Total Period Cost = $9,500.
Example 6: Online Service Annual Costs
Scenario: Estimating annual period costs for an online subscription service.
Known Values: Fixed Costs (Server Hosting Plan, Software Licenses) = $12,000, Variable Costs (Customer Support Costs scaled with users, Transaction Fees) = $5,000.
Calculation: Total Period Cost = $12,000 (Fixed) + $5,000 (Variable)
Result: Total Period Cost = $17,000.
Example 7: Marketing Agency Monthly Costs
Scenario: Calculating a marketing agency's operational costs for a month.
Known Values: Fixed Costs (Office Rent, Core Staff Salaries) = $7,000, Variable Costs (Campaign Specific Software, Freelance Marketer Fees) = $3,500.
Calculation: Total Period Cost = $7,000 (Fixed) + $3,500 (Variable)
Result: Total Period Cost = $10,500.
Example 8: Zero Variable Costs
Scenario: A business has only fixed period costs in a particular month.
Known Values: Fixed Costs (Rent, Insurance) = $1,800, Variable Costs = $0.
Calculation: Total Period Cost = $1,800 (Fixed) + $0 (Variable)
Result: Total Period Cost = $1,800.
Example 9: High Variable, Low Fixed
Scenario: A business with mostly commission-based sales staff and a small office.
Known Values: Fixed Costs (Small Office Rent, Basic Admin Software) = $500, Variable Costs (Sales Commissions, Travel) = $6,000.
Calculation: Total Period Cost = $500 (Fixed) + $6,000 (Variable)
Result: Total Period Cost = $6,500.
Example 10: Annual Summary Costs
Scenario: Summarizing total period costs over a full year.
Known Values: Fixed Costs (Annualized Rent, Salaries, Licenses) = $50,000, Variable Costs (Total annual advertising, supplies, commissions) = $25,000.
Calculation: Total Period Cost = $50,000 (Fixed) + $25,000 (Variable)
Result: Total Period Cost = $75,000.
Frequently Asked Questions about Total Period Costs
1. What are the main components of Total Period Cost?
In a simplified model, it's the sum of Total Fixed Costs and Total Variable Costs incurred during a specific accounting period.
2. How is a Period Cost different from a Product Cost?
Product costs are directly tied to the production of goods (materials, manufacturing labor) and are included in inventory value until the goods are sold. Period costs are expensed in the period they occur and are not tied to inventory.
3. What are common examples of Fixed Period Costs?
Rent for administrative offices, fixed salaries (not direct labor), insurance premiums, property taxes, straight-line depreciation on non-production assets.
4. What are common examples of Variable Period Costs?
Sales commissions, variable utilities for administrative offices, shipping costs (if treated as selling expense), certain marketing costs that vary with sales volume.
5. Why is it important to calculate Total Period Cost?
It's essential for preparing income statements (Profit & Loss), understanding the overall expenses of a business in a given period, and making pricing or budgeting decisions.
6. Does this calculator handle mixed costs (semi-variable costs)?
No, this calculator assumes you have already separated your costs into purely fixed and purely variable components. Mixed costs (like utilities with a base charge plus usage fee) would need to be analyzed and split before using this simple tool.
7. What units should I use for costs?
Use consistent currency units (e.g., USD, EUR, your local currency) for both fixed and variable costs. The total period cost will be in the same currency unit.
8. What period does this calculation apply to?
The calculation is for the specific period for which you enter the total fixed and total variable costs (e.g., a week, a month, a quarter, a year).
9. Are "Operating Expenses" the same as Period Costs?
Often, yes. Operating expenses (OpEx) usually include selling, general, and administrative (SG&A) expenses, which are typically classified as period costs on an income statement.
10. How does knowing Total Period Cost help a business?
It helps in budgeting, break-even analysis, setting sales targets, evaluating profitability, and understanding the overall expense structure separate from production costs.
