Cost-accounting terminology glossary
Fixed costs are costs that do not vary with output within a relevant range.
This definition distinguishes fixed costs from variable costs and fixed manufacturing overhead. It does not identify, classify, allocate, assign, estimate, calculate, validate, record, budget, forecast, price, analyze, recommend, approve, decide, or manage any cost, accounting, financial, tax, legal, operational, or business matter.
Fixed costs are costs that do not vary with output within a relevant range. OpenStax explains that fixed manufacturing overhead is incurred regardless of whether anything is actually produced. The term does not identify a cost, determine a relevant range, assign an accounting treatment, calculate a unit cost, establish a budget, or decide a financial outcome. Read the accounting reference.

Fixed-cost language may appear beside variable costs and fixed manufacturing overhead. The terms can clarify a discussion without identifying a cost, allocating an amount, calculating a unit cost, setting a budget, or determining an accounting result.
Variable costs
Costs that vary with output. The term does not calculate an amount or determine a cost classification.
Fixed manufacturing overhead
A related fixed cost discussed in manufacturing accounting. The term does not allocate overhead or determine inventory value.
Why context matters
A cost label does not establish a financial result.
The important distinction
A glossary defines the term. It does not classify or calculate costs.
The accounting definition provides vocabulary for discussing costs that do not vary with output within a relevant range. It is not a cost classification, allocation, budget, accounting record, valuation, price, tax treatment, financial result, or decision for a specific organization.
Costs, output, context
A term does not calculate a unit cost, budget, or price.
Cost discussions may involve output, products, labor, materials, overhead, budgets, records, inventory, prices, taxes, accounting policies, and requirements. This page does not identify, classify, allocate, assign, estimate, calculate, validate, record, budget, forecast, price, analyze, recommend, approve, or decide any of them.
A source note
Shared terminology can help name a cost-accounting question.
OpenStax explains that fixed manufacturing overhead is incurred regardless of whether anything is produced. That supports a plain-language definition; it does not resolve a cost, accounting, tax, financial, pricing, or operational question.
Keep the definition and the cost decision separate.
An educational source can explain the term. It cannot identify or classify a cost, allocate or assign an amount, calculate a unit cost, set a budget, establish a price, validate a record, or determine an appropriate action.
