O reajuste está na fatura detalhada.

Reajuste usually means an adjustment, increase, or readjustment, depending on context.

In billing or service contexts in Brazil, it often refers to:

• a price increase
• a rate adjustment
• a change in the amount charged

So here, reajuste is probably the extra amount or updated charge that appears on the bill.

Portuguese often uses the definite article more naturally than English does.

So o reajuste means the adjustment or the increase.

Using o here makes the noun sound specific:

• O reajuste está na fatura detalhada. = The adjustment is on the itemized bill.

In English, we might sometimes drop the, but in Portuguese it is very normal to include it.

This is a very common question.

Portuguese has two main verbs for to be:

• ser → used for identity, essence, permanent characteristics
• estar → used for location, condition, temporary state

Here, está is used because the sentence is talking about where the adjustment appears:

• O reajuste está na fatura detalhada.
• Literally: The adjustment is in/on the detailed bill.

Since this is about location, estar is the correct choice.

Na is a contraction of:

• em = in / on / at
• a = the

So:

• em + a = na

That means:

• na fatura detalhada = in the / on the detailed bill

This kind of contraction is extremely common in Portuguese:

• no = em + o
• na = em + a
• nos = em + os
• nas = em + as

Portuguese and English do not always use prepositions the same way.

In Portuguese, em often covers meanings that English splits into:

• in
• on
• sometimes at

So está na fatura is perfectly natural Portuguese, even if English would more naturally say it’s on the bill.

A literal translation might sound like in the bill, but the natural English meaning is usually on the bill or listed on the bill.

Not exactly.

Fatura usually means:

• invoice
• billing statement
• credit card bill
• a formal bill for payment

Conta can mean:

• bill in everyday situations, especially at a restaurant or for utilities
• account
• sometimes a general charge

So fatura sounds a bit more like a formal billing document, and in many contexts it is the best word for invoice or statement.

Because detalhada is describing fatura, and fatura is a feminine noun.

In Portuguese, adjectives usually agree in gender and number with the noun they describe:

• fatura detalhada = feminine singular
• relatório detalhado = masculine singular
• faturas detalhadas = feminine plural

So:

• fatura → feminine
• therefore detalhada must also be feminine

A very natural translation would be:

• itemized bill
• detailed bill
• itemized invoice
• detailed statement

In many real-life contexts, itemized bill is especially natural, because it suggests the charges are broken down clearly.

The basic order is very natural:

• O reajuste está na fatura detalhada.

This follows a common pattern:

• subject + verb + place/location

You could change the order for emphasis, but the original is the most neutral and natural version.

For example:

• Na fatura detalhada está o reajuste.

This is grammatically possible, but it sounds more marked or formal. Most learners should stick with the original order.

A helpful approximate pronunciation is:

oo ray-ah-ZHOO-steh es-TAH nah fah-TOO-rah day-tah-LYAH-dah

A few notes:

• reajuste has the stress on jus
• está has the stress on the final á
• fatura is usually pronounced with stress on tu
• lh in detalhada sounds like the lli in million for many English speakers

A more connected Brazilian pronunciation may sound something like: u he-a-ZHUS-ti es-TA na fa-TU-ra de-ta-LYA-da

Sometimes yes, but they are not always identical.

• aumento = increase, rise
• reajuste = adjustment/readjustment, often used in more formal or administrative contexts

So:

• aumento often focuses on the fact that something went up
• reajuste can sound more official, technical, or contractual

In billing, pricing, salaries, rent, and service plans, reajuste is very common in Brazilian Portuguese.

Not necessarily by itself.

The adjective detalhada describes fatura, not reajuste. So the sentence says the adjustment is found in the detailed/itemized bill.

That means:

• the bill is detailed
• the adjustment appears there

It does not automatically mean that the adjustment itself is explained in detail, although that may be true in context.
