AACE Certified Cost Professional (CCP) Cheat Sheet

May 1, 2026

Review a compact AACE Certified Cost Professional (CCP) cheat sheet for total cost management, estimating, cost control, earned value, risk, communication, and PM Mastery practice.

On this page

Use this AACE Certified Cost Professional (CCP) cheat sheet to review the cost-engineering decisions that tend to separate a defensible cost-control answer from a formula-only answer. Keep the focus on estimate basis, cost baseline, progress evidence, earned value meaning, contingency, change control, and stakeholder communication.

Open AACE CCP practice for the free 120-question diagnostic, topic pages, timed mocks, and the full PM Mastery cost-engineering bank.

Total cost management checklist

Area	What to know	Common trap
Estimate basis	scope, exclusions, assumptions, quantity basis, pricing basis, maturity, and uncertainty	comparing two estimates without checking whether they used the same basis
Cost baseline	approved budget reference, coding structure, control accounts, and authorized changes	treating a forecast update as if it automatically changes the approved baseline
Progress evidence	physical progress, earned value, actual cost, commitments, and remaining work	relying on spend alone as proof of earned progress
Earned value	planned value, earned value, actual cost, cost variance, schedule variance, CPI, and SPI	calculating an index correctly but missing what it means for action
Forecasting	estimate at completion, estimate to complete, variance at completion, trends, and remaining-risk assumptions	assuming a current CPI trend applies to all remaining work without testing the work mix
Risk and contingency	identified uncertainty, contingency, confidence level, risk response, and governance rules	treating contingency as hidden padding rather than a controlled response to uncertainty
Change and claims	entitlement, causation, measured impact, documentation, approval path, and schedule-cost connection	recommending recovery or claim action without traceable records
Communication	issue, evidence, impact, recommendation, assumption, confidence, and next control step	writing a status narrative that reports numbers but does not support a decision

Must-know distinctions

Estimate versus budget versus baseline: an estimate predicts cost, a budget allocates approved funding, and the baseline is the control reference.
Contingency reserve versus management reserve: contingency addresses identified uncertainty; management reserve is usually held outside the controlled baseline for unknowns or executive-level risk.
Direct cost versus indirect cost: direct costs are traceable to a work item; indirect costs support work but are allocated or shared.
Actual cost versus committed cost: actual cost has been incurred; committed cost has been obligated but may not be fully spent.
Cost variance versus schedule variance: cost variance compares earned value with actual cost; schedule variance compares earned value with planned value.
CPI versus SPI: CPI shows cost efficiency; SPI shows schedule efficiency in earned-value terms.
EAC versus ETC: estimate at completion is the expected final cost; estimate to complete is the remaining cost from the status date forward.
Baseline change versus forecast change: a baseline change alters the approved reference; a forecast change updates the expected outcome.
Risk exposure versus realized issue: risk is uncertain; an issue has occurred and needs response, escalation, or control action.
Calculation answer versus management answer: CCP scenarios often need the calculation plus the control meaning behind it.

Formula and calculation cues

Use formulas to support the decision, not to replace judgment. CCP questions often ask what the cost professional should conclude or do after the number is known.

Cue	Formula	How to read it
Cost variance	\(CV = EV - AC\)	Positive is usually favorable; negative means earned value is below actual cost.
Schedule variance	\(SV = EV - PV\)	Positive means earned value is ahead of plan in earned-value terms; negative means behind.
Cost performance index	\(CPI = EV / AC\)	Above 1.0 is usually favorable; below 1.0 means cost efficiency is weak.
Schedule performance index	\(SPI = EV / PV\)	Above 1.0 is usually favorable; below 1.0 means earned progress lags the plan.
Estimate at completion	\(EAC\)	Expected final cost; choose the EAC method that matches the remaining-work assumption.
Estimate to complete	\(ETC = EAC - AC\)	Expected remaining cost from the status date to completion.
Variance at completion	\(VAC = BAC - EAC\)	Expected underrun or overrun compared with the budget at completion.

Strong CCP answers explain the assumption behind the formula. For example, a CPI-based forecast is weaker if the remaining work is materially different from the work already performed.

Common traps

Using a formula result without checking status date, baseline, and data quality.
Confusing estimate maturity with estimate accuracy; an early estimate may need a wider range and more explicit assumptions.
Treating contingency as a place to hide scope gaps or weak estimating.
Ignoring commitments, accruals, or remaining work when judging actual cost performance.
Reporting a favorable schedule index while a near-term milestone or critical interface is still at risk.
Recommending rebaseline before identifying the root cause, approved change path, and control consequence.
Mixing contract entitlement with cost impact; a claim usually needs both support for the right to relief and support for the measured impact.
Writing a communication memo that lists calculations but does not state the issue, evidence, recommendation, and next step.

Practice strategy

After each CCP diagnostic or topic set, classify misses by failure type: estimate basis, baseline control, progress evidence, earned value interpretation, forecast assumption, risk/contingency, change documentation, or communication. If your calculation accuracy improves but scenario judgment stays weak, spend more time explaining what the number means for the project-control decision.

Use the free diagnostic as one realistic checkpoint, then move into topic drills when misses show a pattern. When you can pass several timed mixed attempts above your target score without recognizing repeated items, stop overtraining and focus on exam-day pacing, formula recall, and short written communication discipline.
