One extra open day is worth far more than a day's average revenue, because the value depends entirely on which day it is. An early-season day that lets a resort catch the Christmas peak, or a saved day during a midwinter thaw that keeps terrain open, can each be worth a large multiple of an average midweek day in March. The unit of value in a ski business is not the day — it is the marginal day, priced by demand.
That distinction is the foundation of how snowmaking, and additives in particular, should be valued. If you price snowmaking against the cost of the water and energy it consumes, you miss the point. Its output is protected revenue on specific high-value days. This piece works through what an open day is actually worth, why the average badly understates it, and how that reframes the economics of any tool that adds days.
Key takeaways
- The value of an extra open day is set by demand timing, not by an annual average — peak-period days are worth a large multiple of shoulder-season days.
- Missing a major early-season opening such as Christmas can cost roughly 20% of a resort's annual revenue (industry estimate); New Year's week is typically the single highest-revenue week.
- A resort's revenue per day spans a wide range; skiing accounts for the great majority of revenue and nearly all profit for major operators, so lost ski days hit the bottom line hard.
- Because value concentrates on marginal high-demand days, tools that reliably deliver those days — snowmaking capacity, efficiency, and additives — are priced against protected revenue, not against their input cost.
- This is the logic behind value-share pricing: charge a share of the revenue an extra open day protects, not a per-kilogram additive markup.
What is one extra open day actually worth to a ski resort?
It depends almost entirely on when the day falls. A resort's revenue is not spread evenly across the season — it spikes hard around Christmas, New Year, and peak-holiday weeks, and thins out in the early-December and late-spring shoulders. So a single open day can be worth anything from a modest shoulder-season figure to a large multiple of that at the peak. Averaging across the season hides exactly the days that matter.
The clearest way to see this is through the cost of not opening. Industry estimates hold that missing a major early-season opening — the Thanksgiving or Christmas window — can cost around 20% of a resort's annual revenue, because that period concentrates so much of the year's demand. New Year's week is typically the highest-revenue week of all. A day lost there is not a 1/150th slice of the season; it is a piece of the most valuable fortnight the resort has.
That is why "revenue per open day" is a misleading average unless you attach it to a date. The right question is never "what is a day worth" but "what is this day worth" — and for the days snowmaking exists to protect, the answer is: a lot.
Why does the average revenue-per-day understate the real number?
Because ski demand is sharply seasonal and skiing carries most of a resort's margin. Total winter revenue divided by open days gives a tidy figure, but it blends the packed New Year's week with quiet mid-March Tuesdays. The days a resort fights hardest to open — the early-season base, the holiday peak, the thaw-recovery days — sit at the top of that distribution, not the middle.
Two structural facts amplify the effect:
- Revenue concentration in time. The Christmas–New Year corridor and school-holiday weeks deliver a disproportionate share of the season. Early openings and peak-week reliability protect the fat part of the curve.
- Skiing's share of the P&L. For major operators, skiing represents the great majority of revenue and close to all profit — ancillary lodging, food, and retail largely depend on the lifts turning. A lost ski day therefore drags down more than just lift-ticket sales.
The cost side reinforces the asymmetry. Snowmaking is a major operating line — roughly 17% of daily operating cost at large Alpine resorts, per Vorkauf et al. 2022 — but the revenue it defends is far larger than the cost it carries. The detailed cost anatomy is in the snowmaking cost breakdown. When a large operating spend protects an even larger, timing-concentrated revenue line, the marginal day it saves is worth defending aggressively.
The macro numbers make the stakes concrete. Europe's ski economy is worth on the order of €70 billion a year, and in Austria winter tourism alone contributes around €12.5 billion — some 6.2% of national GDP. Globally, Vanat's International Report on Snow & Mountain Tourism recorded 399 million skier visits in 2024-25, a record. Against that backdrop, a single high-demand open day at a large resort represents a meaningful slice of a very large, very seasonal revenue base — and the volatility is real, with US skier visits falling about 14% in the weather-hit 2025-26 season.
How does the value of a day change across the season?
It rises to a sharp peak around the winter holidays and tapers at both ends. The table below is a directional illustration of the shape of that curve — the relative value of an open day by season segment — not a set of hard figures, which vary widely by resort size, market, and country.
| Season segment | Demand level | Relative value of one open day | |---|---|---| | Early December (pre-peak) | Building | Moderate, but it enables the peak | | Christmas / New Year | Highest of the year | Very high (peak multiple) | | January–February holidays | High | High | | Midweek shoulder (late season) | Low | Low | | Spring closing days | Low–moderate | Moderate |
The important reading is not the individual cells but the spread between them. The gap between a peak day and a shoulder day is what makes timing the whole game. A tool that adds a random day in the low-demand tail is worth little; a tool that reliably secures the Christmas opening or saves a peak-week day during a thaw is worth a large multiple of that. This is why extending the season at the front end — earlier, reliable openings — captures so much more value than adding equivalent days in the shoulder.
How does this reframe the economics of snowmaking and additives?
It moves the entire conversation from cost-per-unit to value-per-day-protected. If snowmaking's output is high-value marginal days, then any tool that reliably delivers those days should be valued against the revenue it protects, not against the water and energy it consumes. That is a different — and much larger — number.
Consider a snowmaking additive in this frame. DeepSnow models that SL6733 delivers a +3 °C wet-bulb advantage worth an estimated 300–500 recovered snowmaking hours per season and a modelled $2.4–2.8M EBITDA uplift on a mid-sized EU resort. Those recovered hours are not generic — they fall disproportionately in the marginal windows that decide whether the resort catches its early opening or holds the surface through a warm spell. In other words, the additive's value is concentrated on exactly the high-value days this piece is about. (All those figures are modelled and pre-commercial.)
This is the reasoning behind value-share pricing: rather than selling an additive at a per-kilogram markup — which would price a parts-per-million dose as a trivial commodity — the value is shared as a fraction of the incremental revenue or EBITDA the recovered days protect. It is how performance inputs are priced in adjacent industries, where a small chemical dose unlocks a large operational gain. The wider adaptation context — why these marginal days grow more valuable as the climate warms — is in will ski resorts survive climate change. And where an additive can legally deliver those days, versus a capital alternative, is compared in additive vs all-weather machine economics.
The bottom line
An extra open day is worth what its date commands, and ski demand loads the value onto a handful of early-season and peak-holiday days. Averages flatten exactly the days that decide a season. Once you price by the marginal day rather than the mean, the economics of snowmaking — and of any additive that reliably recovers marginal hours — shift from a cost line to a revenue-protection line. That is why value-share, not dose markup, is the honest way to price a tool whose real output is high-value open days.
