पोस्टपेड मासिक शुल्क ज़्यादा है।

Because Hindi often borrows English words and writes them in Devanagari.

• पोस्टपेड = postpaid
• मासिक is actually a Hindi/Sanskrit-based word meaning monthly
• शुल्क is a formal Hindi word meaning fee/charge

So this sentence is a very natural kind of modern Hindi mix: some borrowed vocabulary, some native/formal Hindi vocabulary.

Here is the breakdown:

• पोस्टपेड = postpaid
• मासिक = monthly
• शुल्क = fee / charge
• ज़्यादा = more / higher / too much, depending on context
• है = is

So the structure is basically:

पोस्टपेड मासिक शुल्क = postpaid monthly fee
ज़्यादा है = is high / is more

है is the present-tense form of to be for a singular subject.

In this sentence, the main noun is शुल्क (fee/charge), which is treated as singular, so Hindi uses है = is.

If the subject were plural, you would usually use हैं instead.

For example:

• शुल्क ज़्यादा है। = The fee is high.
• शुल्क ज़्यादा हैं। = The fees are high.
  This plural version is less common with शुल्क unless you clearly mean multiple separate charges.

Because Hindi usually follows Subject–Object/Complement–Verb order, and the verb often comes at the end.

English:

• The postpaid monthly fee is high.

Hindi:

• पोस्टपेड मासिक शुल्क ज़्यादा है।
• Literally: Postpaid monthly fee high is.

This verb-final pattern is one of the most important word-order differences between Hindi and English.

Hindi normally does not use articles like a, an, or the.

So:

• शुल्क can mean fee, a fee, or the fee
• The exact meaning depends on context

That is completely normal in Hindi. Learners often expect a separate word for the, but usually there isn’t one.

In this sentence, ज़्यादा means something like more / higher / too much, and in natural English it is often translated as high or expensive depending on context.

So:

• शुल्क ज़्यादा है = the fee is high
• literally, it is closer to the fee is more

Hindi often uses ज़्यादा in places where English might prefer:

• high
• too high
• higher
• more

The best translation depends on the situation.

Good question. In Hindi, some adjectives change for gender/number, but some do not.

ज़्यादा is generally used as an indeclinable word here, so it does not change to match the noun.

Compare this with adjectives that do change, such as अच्छा / अच्छी / अच्छे.

But with ज़्यादा, you usually just keep ज़्यादा:

• कीमत ज़्यादा है।
• फीस ज़्यादा है।
• खर्चे ज़्यादा हैं।

So yes, adjective agreement exists in Hindi, but ज़्यादा is not a good example of a changing adjective.

Yes, you could often say फीस, but the tone is a little different.

• शुल्क = fee / charge
  
  • more formal
  • common in official, business, telecom, banking, educational, and written contexts
• फीस = fee
  
  • very common in everyday speech
  • especially for school, tuition, exam fees, etc.

So in something like a mobile plan or billing context, मासिक शुल्क sounds very natural and slightly formal.

Both are possible, but they feel a little different.

• मासिक शुल्क = monthly fee

  • concise
  • formal
  • common in plans, subscriptions, advertisements, bills

• हर महीने का शुल्क = the fee for every month / the monthly fee

  • longer
  • more explanatory
  • more conversational

So पोस्टपेड मासिक शुल्क ज़्यादा है sounds like the kind of wording you might see in a plan comparison, ad, or customer-service context.

Yes, depending on context, English may translate it that way.

Even though शुल्क is singular in form here, English sometimes prefers:

• The postpaid monthly fee is high
• Postpaid monthly charges are high

The Hindi sentence itself focuses on the idea of the monthly charge/fee being high. English can express that with either singular or plural wording depending on what sounds most natural in context.

Yes, शुल्क is a bit tricky for learners.

A rough pronunciation guide is:

• शुल्क ≈ shulk

The hard part is the consonant cluster. It is said in one compact word, not as separate syllables like shu-lu-ka.

A rough full-sentence pronunciation:

• पोस्टपेड मासिक शुल्क ज़्यादा है
• postpaid maasik shulk zyaadaa hai

A few helpful notes:

• मासिक = maa-sik
• ज़्यादा = zyaa-daa
• है often sounds like hai with an ai sound similar to high, but shorter/smoother in connected speech

Yes, you can, and it is also natural.

• पोस्टपेड मासिक शुल्क ज़्यादा है = compact, headline-like, plan-description style
• पोस्टपेड का मासिक शुल्क ज़्यादा है = explicitly the monthly fee of the postpaid plan is high

Adding का makes the relationship more explicit. Without का, Hindi often allows a noun to directly modify another noun, especially in modern usage and technical/commercial contexts.

So both are acceptable, but the version without का feels shorter and more like product or plan language.

It sounds natural, especially in a telecom, billing, or plan-comparison context.

It has a slightly formal/informational style because of words like:

• मासिक
• शुल्क

A more conversational version might be:

• पोस्टपेड का महीने का खर्च ज़्यादा है।
• पोस्टपेड की फीस ज़्यादा है।

But the original sentence is absolutely natural and useful, especially in written or semi-formal contexts.
