Die Standgebühr beträgt zwanzig Euro.

Because German very often forms compound nouns by joining smaller nouns into one word.

• der Stand = stand, stall, booth, pitch
• die Gebühr = fee

So die Standgebühr means the fee for a stand/stall/booth/pitch.

This is completely normal in German. English often writes these ideas as separate words, but German usually combines them.

In German compounds, the last part usually determines the grammatical gender.

Here, the last part is die Gebühr, which is feminine. So the whole compound is also feminine:

• die Gebühr
• die Standgebühr

That is why the sentence begins with Die Standgebühr.

Stand can have several meanings depending on context. In this sentence, it most likely means something like:

• a market stall
• a booth
• a sales stand
• a fair/exhibition stand
• a pitch

So Standgebühr is the fee you pay for using that stand or space.

beträgt is the 3rd person singular form of the verb betragen.

In this kind of sentence, betragen means:

• to amount to
• to come to
• to be

So:

• Die Standgebühr beträgt zwanzig Euro. = The stand fee amounts to twenty euros.

This verb is common in formal or written German when stating prices, totals, distances, measurements, and so on.

Because the subject is die Standgebühr, which is singular.

The infinitive is betragen, but the sentence needs the conjugated form:

• ich betrage
• du beträgtst (rarely used in this meaning)
• er/sie/es beträgt

Since die Standgebühr is grammatically feminine singular and corresponds to sie in grammar terms, the verb form is beträgt.

This is standard German word order in a simple main clause:

• Die Standgebühr = subject
• beträgt = finite verb
• zwanzig Euro = complement/object-like amount expression

German main clauses normally place the finite verb in second position. So the pattern here is:

Subject + verb + rest

That gives:

Die Standgebühr beträgt zwanzig Euro.

Yes, with betragen, the amount is typically treated as an accusative complement/object.

So in grammatical terms, zwanzig Euro is accusative here. However, you do not see a special ending, because:

• zwanzig does not change here
• Euro after a number usually stays Euro

So even though the phrase is accusative, it looks the same as it would in many other contexts.

In German, after numbers, the currency word normally stays Euro:

• ein Euro
• zwei Euro
• zwanzig Euro

German does not usually add -s the way English does with euros.

The same pattern applies to Cent:

• fünfzig Cent
• zwei Cent

Yes, that is possible, and it sounds natural.

There is a slight style difference:

• beträgt = a bit more formal, factual, official
• kostet = more everyday and conversational

So both are fine:

• Die Standgebühr beträgt zwanzig Euro.
• Die Standgebühr kostet zwanzig Euro.

The first one may sound more like a notice, brochure, price list, or official statement.

It is neutral to somewhat formal.

The wording with beträgt is common in:

• signs
• price lists
• official notices
• websites
• brochures
• contracts or regulations

In everyday speech, many people would more naturally say:

• Die Standgebühr kostet zwanzig Euro.

So the original sentence is perfectly normal, but slightly more formal in tone.

A rough English-friendly guide:

• beträgt ≈ beh-TRAYKT
• Standgebühr ≈ SHTANT-guh-BYOOR

A few important points:

• st at the beginning of Stand is pronounced like sht
• ä in beträgt is roughly like the vowel in air, though not exactly
• ü in Gebühr is a rounded front vowel that English does not really have; it takes practice
• the stress in Standgebühr is usually on -gebühr

If you want a more careful breakdown:

• Stand → Shtant
• Gebühr → guh-BÜHR

Because in German, all nouns are capitalized.

So in this sentence:

• Standgebühr is capitalized because it is a noun
• Euro is also capitalized because it is a noun

This is a basic German spelling rule and applies everywhere, not just at the start of a sentence.

A very literal translation would be:

• The stand fee amounts to twenty euro/euros

But natural English would usually be:

• The stand fee is twenty euros
• The stand fee comes to twenty euros
• The stand fee is twenty euro (less common in standard English)

So betragen often corresponds literally to amount to, but the best English translation depends on what sounds natural.
