Calculate your opportunity with Ersona.
Three calculators with your numbers and visible formulas. No form, nothing stored.
Modelled exampleComputed from your editable assumptions - not a guarantee or a forecast.
Earn
Upsell revenue opportunity.
What extras could be worth across the stays you already host.
Reservations that check out in a typical month - a 60-room hotel at ~70% occupancy and 2–3-night stays is around 500.
Extra revenue, per month
€1,700
≈ €3.40 per stay, on top of the room
Extra revenue in this scenario, per year
€20,400
monthly × 12 · guests you already have, journeys you already run
Adjust assumptionsBased on editable assumptions for stay extras, on-property services and partner services.
For each kind of offer: the share of all stays that buy - eligibility is already inside that number - and what one sale is worth to you.
Stay extras
Late checkout, early check-in, room upgrades
≈ 30 sales · €750 / month
Average price of one extra.
On-property services
Breakfast, parking, spa, packages
≈ 40 sales · €800 / month
Average value of one order.
Partner services
Transfers, tours, local experiences
≈ 10 sales · €150 / month
Your commission, not the guest price.
Retain
Direct revenue opportunity.
What your channel mix costs, and what you keep if some demand books direct.
Rooms revenue you book in a typical month.
Commission retained, per month
€600
if 10% of your OTA demand booked direct
Retained in this scenario, per year
€7,200
retained commission, not profit - at 15% commission
Adjust assumptions40% via OTAs · 15% average commission · modelling a 10% shift to direct.
HOTREC/HES-SO 2024: direct channels were 50.9% of European overnight stays; 28% of hotels sit at 30–49% OTA share.
Editable industry benchmark. The European Commission’s 2023 hotel-distribution study found over two thirds of reported basic rates between 10% and 20% - your contracted rate is in your OTA extranet.

Return
Team time opportunity.
Team hours spent on guest conversations, and how many come back.
Across WhatsApp, email, your website and your PMS inbox.

For reference: EZ Group reports ~90% of guest chats resolved without a person and 51 hours returned to the team per month across 200+ units.

How this is calculated
Formulas, sources and what the model leaves out.
Earn - upsell revenue
Sales = stays × share that buy
Revenue = Σ sales × value to you per sale
Per year = monthly revenue × 12
No independent benchmark exists for upsell conversion, so the starter values are modest - replace them with your own. Partner services count your commission, not the guest price.
Retain - direct revenue
OTA revenue = booking value × OTA share
Commission exposure = OTA revenue × commission
Retained = (OTA revenue × shift × commission) − direct cost
Retained commission is margin kept, not profit and not new revenue. OTAs stay valuable channels.
Return - team time
Hours today = conversations × minutes ÷ 60
Hours returned = hours today × automated share
Set handling time from your own data. The result is team capacity returned, never headcount removed.
Not adjusted for seasonality, cancellations, cost of goods, rate parity or the work needed to shift demand. The three results are never combined into one total.
Where the benchmarks come from
Booking.com and Expedia agree commission per property and market, so every benchmark here is editable.
OTA commission range
“On average, the independent hotels reported basic OTA commission rates of [10-20]%. Over two thirds of the basic commission rates reported are between 10 and 20%.”
