Eight.
That is how many times kalsarikännit occurs in 411.8 million words of Finnish film and television dialogue. In the same text, kiitos occurs 1,015,835 times.
We went looking for the nine words these lists always carry, in the largest downloadable body of Finnish dialogue there is. The result is not the flat debunking we expected.

The top four are controls, there to give the rest a scale. Perkele earns its place in that group by never appearing on a beautiful-words list and outscoring every word that does by a factor of four.
The corpus is 411.8 million alphabetic tokens of Finnish subtitle dialogue. The method is set out in full here and is not repeated.
This pass reads a hand-written list of inflected forms per word, including the plurals and partitives the rare ones actually live in: jokamiehenoikeudet, myötähäpeää, kalsarikännejä. It does not read compounds, derivatives or verbs, which is why sauna comes out low: saunoa and saunailta are invisible to it. Every figure here is a floor.
The corpus is mostly translated dialogue. A word that exists because Finland has an arrangement no other country has is a word a translator never needs. That explains part of the gap, and it does not explain a gap this wide.
The list splits in two
The expected finding was that none of these words gets used. That is not what came back.
Sisu is the one that is genuinely in use, at 3,520 hits for the noun, with the adjective sisukas on top of that.
Whether 3,520 is a lot depends entirely on what you hold it against, and this is where the site’s own post on sisu is doing a different sum. Set beside jaksaa, the ordinary verb for having the energy for something, the famous noun is outnumbered more than ten to one and the conclusion is that Finns use it far less than the reputation implies. Set beside kalsarikännit, it is four hundred and forty times more common. Both are the same 3,520 hits. That post owns the comparison with real Finnish; this one is only comparing the famous words with each other.

Mökki is more ordinary still, at 26.76 per million, which puts a summer cottage in the same frequency band as a great many perfectly plain nouns. It is the most useful word on any of these lists and the one that gets the least attention, because a cottage is not mysterious enough to write a post about.
Then the floor drops. Everything below sauna in the table occurs less than once per two million words, and four of them occur in double digits across the whole corpus.

What the rare ones have in common
They name things outside the speaker rather than states inside one.
Jokamiehenoikeudet is a body of law, published and maintained as such.1 Talkoot is a way of organising unpaid work. Löyly is what the stones do. Kaamos is a fact about latitude. None of them is a subtle emotion that Finnish alone can express, which is how the lists usually sell them.
A word for a local arrangement is rare in dialogue for the same reason that henkilötunnus is: you say it when the arrangement comes up, and it comes up rarely, and everyone present already knows what it is.
Myötähäpeä is the exception in that group, because it is an emotion word rather than an institution, and a useful one.
It is also the one figure here not to trust. Thirty-two hits is a statement about translated film dialogue, where the English said “I couldn’t watch” and the Finnish translator wrote something else. Out in the open, myötähäpeä is the word Finns reach for constantly, and it is the standard Finnish for what English needed “cringe” for. This is where the corpus is measuring itself rather than the country, and talkoot is probably in the same position: a housing-company work party every spring does not turn up in a film.

The one that got famous without being used
Kalsarikännit is the clearest case, and eight occurrences is not a rounding error, it is a result.
The word is real, the practice is real and thoroughly ordinary. What is not ordinary is the international profile, and the story of where that came from is a separate one. A word can be genuine, widely understood, funny, and still almost never spoken, and this is what that looks like in numbers.

1Learn them to recognise, not to deployAll nine are real words and you will meet several of them. Producing one unprompted, on the other hand, is the single most reliable way to sound like somebody who has read a list.

3Keep mökkiIt is the one item on the list with both the frequency and the cultural load. A mökki organises the Finnish summer, and knowing the word tells you what half of July is about.
None of which makes the rare ones worthless. Kaamos matters enormously to the people living through it twice a year, and a word you meet twice a year is still a word.
What the lists cost you is the comparison. They present nine specialised nouns as everyday vocabulary, and the everyday vocabulary they leave out is the part that would actually help you follow a conversation.
