Seasonality
Also called seasonal demand, peak season, low season, Seasonality chart. Last reviewed Oct 21, 2026 by Jeremy Werden
Seasonality is how a short-term rental's bookings, nightly rates and revenue rise and fall through the year. In BNBCalc, a property analysis's Seasonality chart spreads the yearly revenue estimate across the months and compares each month with your break-even, and market pages chart revenue per listing month by month.
How does the Seasonality chart in a BNBCalc analysis work?
For most analyses, BNBCalc takes the yearly revenue and splits it by month, following how revenue per available night moved through the last 12 months in the property's market, for homes with the same bedroom count (or for all homes, if there isn't enough data for that size). If a full 12 months of market data isn't available, every month gets an equal twelfth.
The chart has two tabs:
- Profit, the default, shows each month's revenue minus your Break-even, with cards for Break-even, Avg profit / month and Best profit month. Break-even is your monthly operating expenses plus Mortgage & Taxes, or plus your rent on a Rent analysis.
- Revenue shows each month's revenue, with Avg revenue / month, Best revenue month and Worst revenue month.
Say an analysis estimates $60,000 a year and break-even is $4,564 a month. If July carries 14% of the year's revenue, that's $8,400 and a $3,836 profit, while a February at 5% brings in $3,000, which is $1,564 short. Keep in mind that break-even is the same every month, because BNBCalc spreads your costs evenly across the year, even though costs like cleaning and platform fees rise and fall with bookings in real life.
If you're signed out, the Profit tab is hidden behind a sign-up prompt, while the Revenue tab stays open.
How do BNBCalc market pages show seasonality?
On a market's Marketwide Stats tab, Revenue per listing by bedroom has a Monthly view covering up to 36 months, with one line per bedroom count. Each month's point is that month's revenue divided by the average number of listings open for booking that month, so the peaks and dips give you a feel for the market's busy and quiet months.
Treat the shape as rough, though, and don't use it to measure growth. The chart crosses changes in how the market data was measured and how listings were counted, including within the last 12 months, so comparing one month with another, or with the same month a year earlier, can mislead you.
Why does seasonality matter?
Because cash flow doesn't arrive evenly, which is what the Profit tab of BNBCalc's Seasonality chart is there to show. A home that makes money over the year can still lose money for three or four months in a row, so make sure you've set aside enough to cover the slow months before you count on the yearly figure.
