Fixed Variable Cost Misclassification Check

Review mixed costs treated as pure fixed or pure variable before a model runs on them. Preparation only, not an account action.

What to provide

Cost list with behaviour notes and activity levels for two periods.

How it works

1. Record each cost’s documented behaviour.
2. Compare cost totals against activity change across periods.
3. Flag costs that moved with activity but are modelled as fixed, or vice versa.
4. Return the misclassification list without reclassifying.

The output

cost | modelled_behaviour | activity_change | cost_change | suspected_mixed | model_unproved

Worked fictional example

Fictional support cost modelled fixed at 2,000 rises to 2,300 when volume rises 50%. Treating it as fixed understates cost at higher volumes; it behaves as mixed.

Checks and limits

Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
