Prisøkningen kommer etter avtaleperioden.

Norwegian very often makes compound nouns by joining words together.

• pris = price
• økning = increase

So prisøkning literally means price increase.

Then the ending -en is added to make it definite:

• en prisøkning = a price increase
• prisøkningen = the price increase

This is very normal in Norwegian. Where English often uses two words, Norwegian often uses one compound word.

The ending -en marks the noun as definite.

For masculine nouns:

• en avtale = an agreement
• avtalen = the agreement

The same pattern is used here:

• en prisøkning = a price increase
• prisøkningen = the price increase

So the sentence is talking about a specific price increase, not just any price increase.

In Norwegian, the definite article is often attached to the end of the noun instead of being a separate word like English the.

So:

• English: the price increase
• Norwegian: prisøkningen

That is why you do not need a separate word before it.

Yes, kommer literally means comes, from the verb å komme = to come.

But in Norwegian, just like in English, verbs like come can be used in a slightly broader sense. In this sentence, kommer means something like:

• takes effect
• happens
• arrives
• comes into effect

So it is not necessarily about physically coming somewhere. It is a natural business or administrative way to talk about when something starts happening.

Norwegian often uses the present tense to talk about the future, especially when the timing is clear from the context.

So kommer etter avtaleperioden can mean:

• comes after the contract period
• will come after the contract period

This is very common and natural in Norwegian. English can do something similar too, as in The train leaves tomorrow.

Here etter means after.

So:

• etter avtaleperioden = after the contract period

Be aware that etter can have other meanings in other contexts, such as according to, but in this sentence the meaning is clearly after.

Avtaleperioden is another compound noun:

• avtale = agreement / contract
• periode = period

Together:

• avtaleperiode = contract period / agreement period

And with the definite ending -en:

• avtaleperioden = the contract period

So the sentence refers to a specific agreement period already known from the context.

Because the sentence is referring to a specific contract period, not just any contract period.

Compare:

• etter en avtaleperiode = after a contract period
• etter avtaleperioden = after the contract period

In business, legal, or subscription contexts, the contract period is usually a specific, known period, so the definite form is natural.

Yes, the word order is completely normal.

The sentence follows the basic Norwegian pattern:

• Subject: Prisøkningen
• Verb: kommer
• Time expression: etter avtaleperioden

So it is a straightforward main clause: Prisøkningen kommer etter avtaleperioden.

Yes, you could, but it sounds a bit heavier and is often less natural in ordinary Norwegian.

• Prisøkningen kommer etter avtaleperioden = natural, simple, common
• Prisøkningen vil komme etter avtaleperioden = possible, but often more formal or more explicitly future-oriented

In many everyday contexts, Norwegian prefers the simple present tense when the future time is already clear.

Yes, absolutely. Even though the Norwegian says comes, a more natural English translation in context might be:

• The price increase takes effect after the contract period
• The price increase applies after the contract period
• The price increase comes after the contract period

The best English wording depends on the situation, especially if this is about subscriptions, services, or contracts.

A useful learner-friendly breakdown is:

• pris → roughly prees
• øk → the ø sound does not exist exactly in English; it is somewhat like the vowel in French deux or German schön
• ning-en → ning-en

So you can think of it roughly as:

prees-URK-ning-en
But that is only approximate, especially because ø is hard to represent in English spelling.

The most important thing for learners is to notice that ø is a separate vowel in Norwegian and should not be pronounced like plain o.

It sounds fairly neutral, but it fits especially well in business, contract, subscription, or billing contexts.

It is the kind of sentence you might see in:

• a contract
• a service agreement
• a pricing notice
• terms and conditions

It is not overly stiff, but it is more administrative than casual everyday conversation.

Yes. Some possible alternatives are:

• Prisen øker etter avtaleperioden.
  = The price increases after the contract period.

• Det blir en prisøkning etter avtaleperioden.
  = There will be a price increase after the contract period.

• Prisøkningen trer i kraft etter avtaleperioden.
  = The price increase takes effect after the contract period.

Your original sentence is natural, but these alternatives may sound more direct or more formal depending on the context.
