When listing units on Airbnb, understanding how the Host Service Fee is calculated, recovered, and allocated within CiiRUS ensures your financial reporting and owner payouts remain 100% accurate.
This guide covers how to use the Multiplication Factor to offset Airbnb’s host fee through your guest pricing, and how CiiRUS automatically governs the accounting folio entry.
1. Offsetting the Host Fee (Rate Markup via Multiplication Factor)
Airbnb charges hosts a standard Host Service Fee (typically 15.5%) on reservations.
Because this fee is applied to the overall booking total on Airbnb's platform rather than just the base rental rate, you can use the Multiplication Factor in CiiRUS to increase channel rates so the economic cost of the fee is recovered from the guest.
How to Set the Multiplication Factor
To adjust your pricing structure for Airbnb:
Navigate to Connections > Channel Manager > Airbnb.
Select the applicable listing.
Locate the Multiplication Factor field.
Enter your rate multiplier (for example, entering
1.20increases your base rates by 20% on Airbnb to absorb the host fee and associated channel distribution costs).Save your changes.
Note: The Multiplication Factor is your pricing mechanism to ensure your net rental revenue is protected. It adjusts your outward rates on Airbnb, but it does not dictate the internal folio accounting split within CiiRUS.
2. Automated Host Fee Governance in CiiRUS
Control of Airbnb Host Fee Extras is standardized and managed directly by the CiiRUS integration to eliminate calculation regressions and manual setup errors:
Automated Assignment: CiiRUS automatically assigns the built-in Host Fee Extra (
ABNBSYSTEM) to all Airbnb-connected listings.Zero Manual Setup: You don't need to manually create, assign, or edit Host Fee Extras in the Channel Manager or Reservation Folios.
Universal Application: Governance applies automatically across every listing connected to your Airbnb integration.
3. How the Host Fee Value Is Populated in the Folio
While the system labels the Host Fee Extra as a percentage-based extra in configuration settings, CiiRUS does not calculate this fee locally (it does not run a formula against the rent, clean fee, or taxes in CiiRUS).
Direct API Pass-Through: When a booking is placed or modified, Airbnb calculates its exact Host Service Fee based on their platform pricing and passes that exact monetary figure back to CiiRUS via the integration API.
Folio Line Item: CiiRUS inserts the exact monetary figure provided directly by Airbnb straight into the reservation folio under the Host Fee Extra (
ABNBSYSTEM).
This guarantees that the Host Fee recorded in CiiRUS matches Airbnb’s actual deduction line-for-line without rounding mismatches.
4. Financial Allocation & Accounting (PMC vs. Owner)
The Host Fee Extra is pre-configured to reflect the standard distribution split between the PMC and the property owner:
Entity | Share Allocation |
Owner Share | 100% |
PMC Share | 0% |
Because the Airbnb Host Fee is a channel distribution cost rather than PMC revenue, 100% of the host fee figure sent by Airbnb is allocated to the owner's side of the folio calculation by default.
5. Affected Reservations
Note: This automated governance update took effect on July 24, 2026. Any reservation created prior to this date is considered a historical booking and will remain unchanged unless modified directly by Airbnb.
Automated Host Fee governance applies in the following scenarios:
New Bookings: All new Airbnb reservations created on or after July 24, 2026, automatically adopt the integration-governed Host Fee Extra.
Updated Bookings: Existing reservations created prior to July 24, 2026, receive the updated allocation whenever a price change or reservation modification is pushed from Airbnb.
Historical Bookings: Past, completed reservations retain their original charges and are not retroactively modified.
Frequently Asked Questions
Why doesn't the Host Fee total equal exactly 15.5% of my CiiRUS base rental rate?
Airbnb calculates its Host Fee against their total reservation pricing structure on their platform. CiiRUS receives the finalized host fee figure directly from Airbnb's API and populates that exact amount into the folio, avoiding mathematical rounding or formula mismatches.
Do I need to enable the Host Fee Extra for new listings?
No. As soon as a listing is connected to Airbnb, the integration automatically applies the Host Fee Extra governance.
Can I opt out and manage my own Host Fee Extra?
Automated governance is enabled by default to guarantee calculation accuracy. If your business model requires manual control over a custom Reporting Extra, please contact Support.
Note: Accounts opted out of automated governance assume the risk of potential calculation deviations from Airbnb's enforced financial data.
