What is one booked night actually worth to you?
Vrbo Sponsored Listings charges a flat dollar bid per booked night, five dollar minimum, no maximum. Five dollars on a $150 night is 3.3% of your rent. The same five dollars on a $400 night is 1.25%. Below some rate, the floor stops paying for itself. Set your own numbers and find out where that line sits for you.
What this unit actually rents for on an average night.
What you charge the homeowner as a percentage of rent.
Nobody knows this number off the top of their head, including us. Vrbo's dashboard can't tell you either, it counts every booking that merely touched an ad. Pick based on how this unit already does without help:
Expedia's own pilot claims 49% booking growth for participating properties. Treat that as the platform's best case, not your number, until a real test tells you yours.
You probably don't know your own number here either. This is Pacer's real, verified vrbo-channel rate, book-wide, trailing 12 months. It's a reasonable default, leave it as-is unless you actually have your own figure.
12.8% book-wide across Pacer's managed portfolios. Yours may run higher or lower by market and season.
Vrbo's floor is $5 with no maximum. Test the floor, or whatever you're actually considering.
Two examples, not two formulas
The math above is the whole tool. Here is what it actually means, worked through twice.
A $250 a night unit, you keep 20% as your fee. That's $50 of your own money on the line, not the nightly rate. Now guess how much of that is truly new business. Say a quarter of the bookings this ad produces would not have happened without it, that's $12.50. Knock off the roughly 13 bookings in 100 that cancel and still get billed, and you land near $11.
Eleven dollars of real room against Vrbo's five dollar floor. You have about double the cushion you'd think if you priced this off the nightly rate instead of your own fee.
Now a $120 unit with a thinner 22% fee. That's $26 of your own money on the line. This unit already books well on its own, so guess lower on new business, say 15%. That's about $4. Same last step, knock off cancellations.
About $3.56. The five dollar floor just went from a good bet to a bad one, on a unit that looks nothing like the first one. Same platform, same five dollar number, opposite answer.
Nothing about the floor changed between those two examples. What changed is what the manager actually keeps, how much of the booking was ever really up for grabs, and how often it falls through. That is the whole argument for running your own numbers instead of trusting a single headline bid.
Bid the gap nights, not the peak weekends
ADR and incrementality move with the season, and they pull in opposite directions.
Peak weekends carry your highest ADR, which raises the ceiling on what is rational to bid. But peak weekends also tend to book on their own. Organic demand is already strong, so a booking Vrbo's ad appears to "produce" there is more likely one you would have gotten anyway, which pushes real incrementality down right where the math looks most tempting.
Shoulder season and gap nights run the opposite way. Lower ADR lowers the ceiling, but a booking that fills a night that would otherwise sit empty is much more likely to be genuinely new revenue, not a booking you already had coming.
Run this calculator once per season instead of once for the year. The best case for paid placement is usually the dates that were already the hardest to fill organically, not your best weekends.
Where your rate sits
Real ADR distribution across Pacer's managed book, trailing 12 months, confirmed stays. Not the industry, just a reference point so you're not eyeballing this blind.
At a 20% fee and 15% incrementality, roughly half of a typical managed book sits close to or below the rate where a $5 bid stops making sense once cancellations are counted. At 25% incrementality that share drops to roughly a quarter. That is not a claim about any specific portfolio, it is why the sliders matter more than the headline.
Incrementality cannot come from Vrbo's dashboard
Vrbo's attribution counts every booking that merely touched an ad. That structurally overstates the pilot numbers a platform will always lead with.
Think of it like paying for a billboard on a road guests already drive. Some stop because of the sign. Most were headed to your listing anyway. The honest number is whichever share actually needed the sign, and no dashboard, Vrbo's included, can tell you which guests are which.
The only honest read is a holdout test: match units on bedroom count, ADR band, and market, run ads on one arm and nothing on the other for four to six weeks, then compare total booked nights and RevPAR across both arms, never ad-attributed bookings alone. The delta is real incrementality.
That takes a book large enough to split into matched pairs and still have a real ad presence in each arm. It is a pilot conversation before it is a math problem.
This calculator only answers whether paid placement pencils for the manager. That is not the only win worth having. If paying for placement moves a booking earlier, which typically avoids the rate erosion that comes with last-minute discounting, the homeowner can net more even when the manager's own math comes out close to breakeven. That is a real reason to test placement on a portfolio at the margin. The manager is not the only one whose numbers matter here.
