월 이용료 means monthly usage fee, monthly fee, or monthly subscription fee, depending on context.

• 월 = month / monthly
• 이용료 = usage fee or fee for using a service

So together, 월 이용료 is the fee you pay every month for using something.

를 is the object marker. It shows that 월 이용료 is the thing being paid.

So in:

• 월 이용료를 오늘 냅니다

the thing being paid is:

• 월 이용료를 = the monthly fee

A very literal breakdown would be:

• 월 이용료를 = the monthly fee + object marker
• 오늘 = today
• 냅니다 = pay

냅니다 comes from the verb 내다, which can mean to pay, to submit, or to hand in, depending on context.

In this sentence, it means to pay.

Conjugation:

• dictionary form: 내다
• formal polite present/future: 냅니다

So:

• 냅니다 = pay / will pay in a formal polite style

Korean present-tense forms often cover both present and future, depending on context.

So 냅니다 can mean:

• pays
• am paying
• will pay

Here, because of 오늘 (today), the sentence is naturally understood as something like:

• I’m paying the monthly fee today
• I will pay the monthly fee today

Korean often relies on context instead of marking future as explicitly as English does.

In Korean, time expressions like 오늘 often come before the verb.

So this order is very natural:

• 월 이용료를 오늘 냅니다

Korean word order is more flexible than English, but the verb usually comes at the end. Time words often appear somewhere before that final verb.

You could also say:

• 오늘 월 이용료를 냅니다

This is also natural. The difference is mostly about emphasis or flow, not basic meaning.

The subject is omitted because Korean often leaves out subjects when they are understood from context.

So 월 이용료를 오늘 냅니다 could mean:

• I pay the monthly fee today
• We pay the monthly fee today
• He/She pays the monthly fee today

In real conversation, the listener usually already knows who the subject is.

This omission is very common in Korean and often feels strange to English speakers at first.

냅니다 is in the formal polite style.

This style is commonly used in:

• announcements
• business situations
• customer service
• presentations
• careful or respectful speech

Compare:

• 내요 = polite casual
• 냅니다 = formal polite

So this sentence sounds a bit more formal and official than 월 이용료를 오늘 내요.

Yes. 월 can mean month or moon, depending on the word and context.

Here, because it appears in 월 이용료 and talks about a fee, it clearly means month / monthly.

So learners should rely on context:

• 월 이용료 = monthly fee
• not anything related to the moon

Yes, it is understandable and natural in many contexts, especially for service fees. But depending on the situation, Korean might also use expressions like:

• 월 사용료 = monthly usage fee
• 월 요금 = monthly charge
• 이용료 = usage fee
• 회비 = membership fee
• 구독료 = subscription fee

The exact best choice depends on what is being paid for.

For example:

• gym membership: 월 회비
• phone or internet: 월 요금
• app or platform: 월 구독료

But 월 이용료 is perfectly reasonable for a general monthly usage fee.

Yes, and it changes the nuance slightly.

• 월 이용료를 오늘 냅니다
  → simply states that you pay the monthly fee today

• 월 이용료는 오늘 냅니다
  → puts 월 이용료 in the topic position, often with a slight contrastive feeling, like:
  As for the monthly fee, I’m paying it today

Using 는 can sound like you are distinguishing it from something else.

For example, it may imply:

• the monthly fee is paid today, but something else is not
• regarding the monthly fee specifically, today is the payment day

So both are possible, but 를 is the more neutral choice here.

Because 오늘 as a time expression usually does not need a particle in a basic sentence.

So Korean commonly says:

• 오늘 냅니다 = pay today
• 내일 갑니다 = go tomorrow
• 어제 만났어요 = met yesterday

Time words often appear without particles unless there is a special reason for emphasis or contrast.

So 오늘 by itself is normal and natural here.
