AHLEI CHRM common mistakes
AHLEI CHRM · Understand the traps and how to avoid them.
Computing RevPAR by adding ADR and occupancy or by multiplying occupancy by total rooms rather than by multiplying ADR by occupancy percentage (or dividing room revenue by available rooms).
Candidates memorize 'RevPAR = ADR × occupancy' but confuse RevPAR with TrevPAR, or substitute rooms sold for rooms available when working from a raw data table.
What to do instead
Before each calculation, write the formula and label the inputs: RevPAR = Room Revenue ÷ Rooms Available = ADR × Occupancy %. Verify by cross-checking the two methods against each other.
Treating occupancy, ADR, and RevPAR as independent levers when evaluating a rate or discount decision, rather than modeling the displacement and net revenue effect of the change.
Candidates focus on the metric named in the question and ignore that a rate cut raises occupancy while possibly lowering total room revenue.
What to do instead
For every pricing or discount question, compute revenue under both scenarios (current ADR × current rooms vs. new ADR × projected rooms) and state which produces higher total revenue before selecting an answer.
Applying a straight percentage to last year's actuals for a budget without adjusting for known changes in demand, rate strategy, new supply, or one-time events.
Candidates default to the simplest historical-trend method and overlook that budgets must reflect current market conditions and management assumptions.
What to do instead
Build the budget from documented assumptions: market demand growth, planned rate changes, new competitive supply, and known events. State each assumption explicitly and tie the number to it.
Confusing segmentation terms-transient vs. group, negotiated vs. corporate, OTA vs. direct-and misclassifying a booking when computing segment mix or channel cost.
Definitions overlap in practice and candidates rely on surface cues (e.g., 'company' implies corporate negotiated) rather than the booking's actual terms.
What to do instead
Learn each segment by its defining characteristic (who pays, who books, rate basis, cancellation terms). Practice sorting sample bookings into segments and justify each placement.
Comparing channel performance on ADR alone without netting out commission, transaction fees, and loyalty costs to get net revenue per channel.
Candidates see a higher gross rate on an OTA or wholesaler and conclude it is the better channel, ignoring distribution cost.
What to do instead
Always compute net ADR = gross rate − (commission % × rate) − per-booking fees. Rank channels by net revenue contribution, not gross rate.
Selecting a forecast method (moving average, pickup, booking curve) without checking whether its assumptions match the data pattern-e.g., applying a simple average to data with strong seasonality or trend.
Candidates memorize method names and pick the most familiar one rather than matching the method to the data's structure.
What to do instead
Before choosing a method, identify whether the series has trend, seasonality, or neither. Use moving averages for level data, seasonal indices for recurring patterns, and pickup/booking-curve methods for short-term room forecasts.
Reporting a variance as favorable or unfavorable based only on whether the dollar figure is above or below budget, without considering whether the line item is revenue or expense.
Candidates apply a single rule ('over budget is bad') and misclassify expense overruns as favorable or revenue shortfalls as neutral.
What to do instead
For every variance, first classify the account as revenue or cost, then determine direction: revenue above budget = favorable; expense above budget = unfavorable. State the classification in your reasoning.
Answering ethics and leadership scenarios with the legally permissible option rather than the option consistent with the property's policy, disclosure obligations, and stakeholder fairness.
Candidates equate 'not illegal' with 'ethical' and overlook AHLEI's emphasis on integrity, transparency, and duty to guests, owners, and employees.
What to do instead
Evaluate each scenario against three tests: Is it honest and fully disclosed? Does it respect all stakeholders? Would it withstand public scrutiny? Choose the option that satisfies all three, even if a legal alternative exists.
Treating revenue management as a pricing-only function and omitting its role in inventory control, overbooking, length-of-stay restrictions, and displacement analysis.
Candidates associate revenue management with rate setting and forget the inventory and mix levers that determine total revenue.
What to do instead
For each scenario, list all levers available-rate, inventory allocation, restrictions (min LOS, closed-to-arrival), overbooking level, and segment mix-then evaluate which combination maximizes net revenue.
Ignoring the distinction between occupied rooms, available rooms, and out-of-order/out-of-service rooms when computing occupancy and availability-based metrics.
Candidates use total room count as the denominator without subtracting out-of-order rooms, inflating or distorting occupancy and RevPAR.
What to do instead
Establish the denominator first: Available Rooms = Total Rooms − Out-of-Order Rooms. Use available rooms consistently in occupancy, RevPAR, and availability calculations, and note the adjustment in your work.
