Fixed cost
Fixed cost is costs that stay constant in total regardless of production or sales volume within a relevant range. For fixed cost, the important details are the accounting period, source evidence, reviewer, materiality threshold, and control purpose that make the treatment auditable during close, reporting, and later review.
Also known as fixed costs, fixed expenses
Why it matters
Understanding fixed cost matters because close, reconciliation, and audit work depend on consistent timing, source evidence, review thresholds, and ownership. A loose definition creates avoidable rework. Pluvo classifies and tracks fixed costs across connected systems and flags when a supposedly fixed line starts moving with volume.
In practice
Revenue example
Teams use fixed cost when they need to separate customer, contract, billing, recognition, and cash effects. That prevents a revenue movement from being misread as growth, churn, expansion, or timing noise.
Pluvo example
Pluvo classifies and tracks fixed costs across connected systems and flags when a supposedly fixed line starts moving with volume.
In practice, teams should define fixed cost with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

A strong workflow for fixed cost separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.

In this glossary, it covers costs that stay constant in total regardless of production or sales volume within a relevant range, so teams should compare those boundaries before using it in reporting or planning.
What are examples of fixed costs?
For fixed cost, the useful categories depend on costs that stay constant in total regardless of production or sales volume within a relevant range. Teams should name the categories they use, map each one to source data, and keep the same taxonomy across reporting periods.
Is rent a fixed cost?
Teams use fixed cost when they agree on the source data, time period, owner, and decision it supports. Here, it covers costs that stay constant in total regardless of production or sales volume within a relevant range, so the term should be reviewed before it is used in reporting, planning, or operating decisions.
