How to Calculate Your True OTA Margin
Your true OTA margin is what you actually keep on a booking after every cost is subtracted, the OTA’s distribution cost and the cost of delivering the experience itself, not just the commission line on your payout report. Most operators calculate one and call it the other.
Ask an operator what they make on their best-selling GetYourGuide product and most will quote the number left after commission. That’s not their margin. It’s their net distribution revenue. The guide’s wages, the ingredients, the entry tickets, the insurance allocation, none of that has been subtracted yet, and by the time it is, the number is often a fraction of what the operator believed.
This guide walks through the full calculation: real distribution cost, real cost of delivery, and a worked example showing exactly how far apart “what I thought I made” and “what I actually made” can be.
Key Takeaways
- True OTA margin means gross booking price minus distribution cost minus the cost of delivering the experience. It is not the same as your effective commission rate, which only covers the first half.
- Most operators only subtract commission from the retail price and call the remainder their margin. That figure is net distribution revenue, not profit.
- Delivery cost, guide wages, materials, entry fees, insurance, allocated overhead, stays constant regardless of which channel sells the booking. Distribution cost varies enormously by channel. That gap is where true margin actually lives.
- A product can be an operator’s best seller by volume and their worst performer by true margin, and volume makes that easy to miss.
- Run this calculation per product per platform, not once for the whole business. The answer is rarely the same twice.
Why Effective Commission Rate Isn’t the Same as True Margin
Your effective commission rate, covered in full in Commission Models for Tour Operators, measures the real cost of distribution: commission plus the extras that don’t show up in the headline rate, payment processing, promotional discounts, cancellation exposure. It answers “what does this platform actually cost me to sell through.”
True margin asks a different question: “what did I actually keep.” It takes the answer to the distribution question and subtracts a second number entirely, the cost of running the tour or delivering the experience. Two operators can have identical effective commission rates and wildly different true margins, because their delivery costs differ.
This is also a different question from pricing structure. Net Rate vs Gross Rate in Tourism explains who sets your retail price. That’s worth knowing. It doesn’t tell you what you’re keeping.
Step 1: Find Your Real Distribution Cost
Pull actual payout data for the specific product and platform, over a recent settlement period, not the contract rate.
Formula: distribution cost % = 1 – (net payout ÷ gross booking value)
If a £65 booking paid out £47.45, your distribution cost on that platform is 27%, not whatever your contract technically says. The gap between the contract rate and this real figure usually comes from processing fees, promotional participation, and cancellation adjustments, all covered in detail in the commission models guide linked above. Don’t re-derive that work here. Just get the real number for the product and platform you’re calculating.
Step 2: Add Up What It Actually Costs to Deliver the Experience
This is the half most operators skip, and it’s the half that turns a healthy-looking payout into a thin true margin.
Split delivery cost into two groups.
Variable costs per booking:
- Guide or staff wages for that departure
- Fuel, transport, or vehicle costs
- Entry tickets, venue fees, or materials consumed (food, equipment, supplies)
- Any add-ons included in the price (a drink, a printed guide, a rental item)
Fixed costs allocated per booking:
- Insurance, divided across expected annual volume
- Booking or channel management software
- A share of marketing spend
- Admin and account management time
Formula (adapted from standard tour-costing practice): cost per booking = (fixed costs ÷ average bookings) + variable cost per booking
Most operators can pull variable costs from their own operational records within minutes. Fixed-cost allocation takes a bit more thought, but a rough allocation is far more useful than skipping it entirely, which is what most operators currently do.
Step 3: Calculate True Margin (Worked Example)
A food tour operator in Bristol lists a two-and-a-half-hour tasting walk at £65 per person on GetYourGuide. Group size averages eight.
Distribution cost: effective rate of 27% (from Step 1) = £17.55. Net distribution revenue = £47.45.
Delivery cost:
- Guide fee for the departure: £120, split across 8 guests = £15.00
- Tastings and ingredients: £12.00 per guest
- Market stall and venue fees: £3.00 per guest
- Insurance allocation: £2.00 per guest
- Software and admin allocation: £1.50 per guest
- Total delivery cost: £33.50
True margin: £47.45 – £33.50 = £13.95 per booking, or 21.5% of the £65 retail price.
Compare that to what most operators would report if asked: £65 minus the 25% contract commission (£16.25) is £48.75, a 75% margin. That’s the number sitting in most operators’ heads. It’s not their margin. It’s what’s left before a single delivery cost is subtracted, and the true figure is less than a third of it.
A kayaking and paddleboard operator in Pembrokeshire ran this calculation across their full product catalogue for the first time, expecting a few minutes of confirmation rather than any real surprises. Their best-selling GetYourGuide product, a two-hour coastal paddleboard session, had been the obvious star of the business by volume for two seasons running. Once delivery costs were properly allocated, guide time, equipment wear, insurance, and the platform’s real distribution cost, the true margin came out under 20%. A quieter product, a half-day sea kayaking trip they’d been quietly considering dropping due to low booking numbers, turned out to sit closer to 45% once the same calculation was applied. The volume had been masking the difference the whole time. They didn’t drop the paddleboard session, but they stopped pushing marketing spend toward it and started promoting the kayaking trip instead.
Why the Same Product Can Have a Different True Margin on Different Channels
Delivery cost doesn’t change by channel. The guide still needs paying, the tastings still need buying, whether the booking arrived through GetYourGuide, Viator, or your own website. Distribution cost is what moves.
Take the same Bristol food tour, booked directly through the operator’s own site instead. Payment processing runs closer to 3% instead of 27%. Distribution cost drops to roughly £1.95. True margin becomes £65 – £1.95 – £33.50 = £29.55, or 45.5%, more than double the OTA figure, on the exact same experience.
That gap is the real argument for building direct bookings alongside OTA distribution. Not because OTAs are bad. Because the same product’s true margin can differ by a factor of two depending purely on how it was sold.
What to Do Once You Know Your True Margin
If a product’s true margin on a given platform is thin or negative, there are three real options.
Renegotiate the commission. Only realistic with consistent volume; the pillar guide above covers when and how.
Reprice for that specific channel. If parity terms allow it, or through add-ons and inclusions rather than price, adjust what that channel needs to charge to protect margin.
Deprioritise that channel for that product. Not every product needs to be on every platform. A product with thin OTA margin and strong direct margin might be better marketed away from OTAs entirely.
If true margin is healthy, that’s the product-channel combination worth protecting, and, where capacity allows, scaling deliberately rather than accidentally.
Most operators have never run this calculation, not because it’s difficult, but because the data lives in three different places: booking software, OTA payout reports, and the accounting system. Pulling it together once is the hard part. After that, it’s ten minutes per product.
A Simple Worksheet to Repeat This
For each product, on each platform:
- Gross retail price
- Net payout received (from platform payout report)
- Distribution cost = price minus payout
- Guide, staff, and materials cost for that departure, per guest
- Allocated fixed costs per guest (insurance, software, marketing, admin)
- Total delivery cost = step 4 plus step 5
- True margin = price minus distribution cost minus delivery cost
Know the Number Before You Trust It
Commission is one line in a bigger equation. True margin, price minus distribution cost minus delivery cost, is the number that actually tells you whether a channel and a product are worth keeping.
Run the calculation on your best-selling product first. It’s the one most likely to surprise you.
OTA Commission Models for Tour Operator
Delivery costs, commission rates, and payout terms vary by operator, product, and platform, and change over time. Figures in the worked example above are illustrative. Run the calculation against your own real payout and cost data before making pricing or channel decisions.
