רוב הכסף שהיא מעבירה לחיסכון נשאר שם עד סוף השנה.

Yes. רוב הכסף means most of the money.

A useful pattern is:

• רוב + definite noun = most of the ...
• רוב האנשים = most of the people
• רוב הזמן = most of the time
• רוב הכסף = most of the money

Here, רוב means most, and הכסף is the money.

Because Hebrew often uses a definite noun after רוב when English would say most of the ....

So:

• רוב הכסף = most of the money
• רוב הספרים = most of the books

If you said just רוב כסף, that would sound unnatural in normal Hebrew.

It is really two parts written together:

• ש־ = that / which
• היא = she

So שהיא literally means that she.

In this sentence:

• הכסף שהיא מעבירה לחיסכון = the money that she transfers to savings

This is very common in Hebrew. The ש־ attaches directly to the next word.

מעבירה is the present-tense feminine singular form of the verb להעביר, which often means:

• to transfer
• to move
• to pass along

Here it means transfers or moves over financially.

Because the subject is היא (she), the verb must be feminine singular:

• הוא מעביר = he transfers
• היא מעבירה = she transfers

Because Hebrew present tense is often used for:

• habitual actions
• general truths
• repeated behavior

So שהיא מעבירה does not mean only she is transferring right now. It can also mean:

• that she transfers
• that she usually transfers
• that she moves into savings

Likewise, נשאר can mean stays / remains as a general fact.

לחיסכון is made of:

• ל־ = to / for / into
• חיסכון = saving / savings

So לחיסכון means something like:

• to savings
• into savings
• for savings

In natural English, you would usually translate it as into savings or to a savings account / savings fund, depending on context.

Because the sentence does not specify exactly which savings vehicle it is. It just says the money goes into savings in a general sense.

Hebrew often leaves this broad:

• מעבירה לחיסכון = transfers into savings

If you wanted to be more specific, you could say things like:

• לחיסכון שלה = to her savings
• לחשבון החיסכון = to the savings account

But the original sentence stays general.

Because in Hebrew the head of the phrase is רוב or the noun כסף, and כסף is an uncountable masculine singular noun.

So Hebrew treats this as singular:

• רוב הכסף נשאר = most of the money stays

Compare:

• רוב הכסף נשאר — singular verb
• רוב האנשים נשארים — plural verb is also common with a plural count noun like people

With כסף, singular is the natural choice.

שם literally means there.

In this sentence, it refers back to the place where the money was transferred — in other words, in savings.

So:

• נשאר שם = stays there

In smoother English, you might not always translate שם literally. Depending on the context, it may come out as:

• stays there
• remains there
• stays in savings

Because סוף השנה is a very common Hebrew construct phrase meaning the end of the year.

This is called a construct chain:

• סוף = end
• השנה = the year
• סוף השנה = end of the year / the year's end

So:

• עד סוף השנה = until the end of the year

You could say עד הסוף של השנה, but it is less natural here and more wordy.

The sentence breaks down like this:

• רוב הכסף = most of the money
• שהיא מעבירה לחיסכון = that she transfers to savings
• נשאר שם = stays there
• עד סוף השנה = until the end of the year

So the full structure is:

• main subject: רוב הכסף
• relative clause describing that money: שהיא מעבירה לחיסכון
• main verb: נשאר
• adverb/place word: שם
• time phrase: עד סוף השנה

In this sentence, the natural form is שהיא מעבירה because the subject she needs to be clear.

You can sometimes get reduced relative clauses in Hebrew, but not in this structure in a normal, natural way.

So:

• הכסף שהיא מעבירה לחיסכון = the money that she transfers to savings

is the normal phrasing.

Often, but not always directly.

In sentences like this, ש־ introduces a relative clause, so it often corresponds to:

• that
• which
• sometimes nothing at all in natural English

For example:

• הכסף שהיא מעבירה = the money that she transfers

In natural English, you might even say:

• the money she transfers

So ש־ is grammatically important in Hebrew even when English can omit that.

A very literal translation would be:

Most of the money that she transfers to savings stays there until the end of the year.

That is already fairly natural English, which is nice for learners. The only slightly flexible parts are:

• מעבירה לחיסכון = transfers to savings / moves into savings
• שם = there / in savings

So depending on context, a translator might also say:

Most of the money she puts into savings stays there until the end of the year.
