Jag jämför allt förutom månadsavgiften.

Because jämför is the present tense form of the verb, while jämföra is the infinitive.

• att jämföra = to compare
• jag jämför = I compare / I am comparing

In this sentence, the subject is jag (I), so Swedish uses the present tense verb form:

• Jag jämför allt ... = I compare everything ...

Unlike English, Swedish does not change the present tense verb depending on the subject:

• jag jämför = I compare
• du jämför = you compare
• han/hon jämför = he/she compares

The verb stays jämför for all persons.

Allt means everything.

This comes from the word all, but Swedish changes it depending on grammar. Here, allt is the neuter singular form, and it is often used in the sense of everything.

Compare:

• all = all / whole (common gender singular)
• allt = all / everything (neuter singular)
• alla = all (plural)

Examples:

• all tid = all the time
• allt är klart = everything is ready
• alla hus = all houses

So in your sentence, allt is the natural word for everything.

Förutom means except, except for, or apart from.

In this sentence:

• Jag jämför allt förutom månadsavgiften.
• I compare everything except the monthly fee.

It introduces the thing that is not included.

A few similar examples:

• Alla kom förutom Anna. = Everyone came except Anna.
• Jag gillar allt förutom kaffe. = I like everything except coffee.

They are very similar, and both can often mean except. But förutom is usually the more common and natural choice in many everyday sentences like this one.

For example:

• Jag äter allt förutom fisk. = I eat everything except fish.
• Jag äter allt utom fisk. = also possible

In many contexts, both work, but förutom can also sometimes mean besides or in addition to, depending on the sentence. Because of that, learners often find it safest to learn förutom first as except for / apart from and then notice the wider uses over time.

Månadsavgiften means the monthly fee.

It is made up of:

• månad = month
• månads- = monthly / month-related
• avgift = fee
• avgiften = the fee

So:

• månadsavgift = monthly fee
• månadsavgiften = the monthly fee

This is a very common Swedish pattern: one noun is placed before another to make a compound word.

Other examples:

• bil
  • dörr = bildörr = car door
• sommar
  • jobb = sommarjobb = summer job

Swedish often adds an -s- between parts of a compound word. This is sometimes called a linking s.

So:

• månad
  • avgift becomes månadsavgift

You cannot always predict perfectly when this happens, so it is something learners gradually get used to by seeing many examples.

Other compounds with a linking -s-:

• arbetsdag = workday
• livsmedel = food products
• samhällsproblem = social problem

So the -s- here is normal and not a separate word.

Because Swedish usually puts the definite article at the end of the noun as a suffix.

• en avgift = a fee
• avgiften = the fee

This is very different from English, where the is a separate word before the noun.

So:

• månadsavgift = monthly fee
• månadsavgiften = the monthly fee

This tells us that the speaker means a specific monthly fee, not just any monthly fee.

Because in Swedish, definiteness is often shown by adding an ending to the noun instead of using a separate word.

So English:

• the monthly fee

becomes Swedish:

• månadsavgiften

The -en at the end carries the meaning of the.

Sometimes Swedish uses both a separate determiner and a definite ending, especially with adjectives:

• den stora bilen = the big car

But in your sentence there is no adjective before månadsavgiften, so the ending alone is enough.

The basic word order is:

subject + verb + object + exception phrase

So here:

• Jag = subject
• jämför = verb
• allt = object
• förutom månadsavgiften = exception phrase

That gives:

• Jag jämför allt förutom månadsavgiften.

This is very normal Swedish main-clause word order.

Yes, Swedish can move elements to the front for emphasis, but then the verb must still stay in the second position in a main clause.

For example:

• Allt jämför jag förutom månadsavgiften.

This is grammatical, but it sounds much more marked or literary. The neutral, everyday version is:

• Jag jämför allt förutom månadsavgiften.

Swedish follows a V2 rule in main clauses, which means the finite verb usually comes in the second position.

A rough guide is:

• jämför ≈ YEM-fur

A few important sounds:

• j in Swedish is usually like English y
• ä is similar to the vowel in bed, though not exactly the same
• ö has no exact English equivalent; it is a rounded front vowel

So jämför starts with a y sound, not a hard English j.

A rough guide is:

• förutom ≈ fur-oo-TOM

Things to notice:

• ö again is not a normal English o
• the stress is usually on the last syllable: -tom

This word may feel tricky at first because of the Swedish ö, but it becomes easier with listening practice.

Yes, it is a completely natural Swedish sentence.

It sounds like something someone might say when talking about comparing offers, subscriptions, prices, contracts, or services:

• Jag jämför allt förutom månadsavgiften.
• I compare everything except the monthly fee.

For example, the speaker might mean they are comparing features, quality, and conditions, but not the monthly charge.

Yes. Depending on context, förutom can sometimes mean besides or in addition to, not only except.

For example:

• Förutom svenska talar hon engelska. This can mean Besides Swedish, she speaks English.

But in your sentence, the meaning is clearly except for:

• Jag jämför allt förutom månadsavgiften.

So context tells you whether it means excluding something or in addition to something.
