Вычитку закончили, с тем чтобы согласовать окончательный расчёт.

This is a very common Russian pattern called an indefinite-personal construction.

Russian often uses a 3rd person plural verb with no subject when the speaker does not name who did the action, or when the doer is obvious from context.

So закончили literally looks like they finished, but in English it may correspond to:

• they finished
• we finished
• someone finished
• a passive-like idea such as the proofreading was finished

The sentence focuses on the fact of completion, not on who completed it.

Вычитку is the accusative singular of вычитка.

• вычитка = proofreading, proofread checking, editorial checking of a text
• вычитку = proofreading (as the direct object)

Here it is the thing that was finished, so it must be in the accusative case:

• закончить что? → вычитку

This noun is feminine, and feminine nouns in -а usually change to -у in the accusative singular:

• вычитка → вычитку

Because с тем чтобы introduces a subordinate clause of purpose.

Russian normally separates this kind of purpose clause with a comma:

• Вычитку закончили, с тем чтобы согласовать...

So the comma works much like in English before expressions such as so that or in order to, especially in more formal writing.

Here the comma marks the boundary between:

1. the main clause: Вычитку закончили
2. the purpose clause: с тем чтобы согласовать окончательный расчёт

С тем чтобы means so that, in order to, or with the aim of.

It is a formal/bookish expression. You are more likely to see it in:

• official writing
• business language
• reports
• legal or administrative style

In everyday Russian, a simpler version is often used:

• чтобы
• для того чтобы

So this sentence sounds more formal than:

• Вычитку закончили, чтобы согласовать окончательный расчёт.

The meaning is similar, but с тем чтобы sounds more official and deliberate.

After a purpose expression like с тем чтобы, Russian often uses the infinitive when the action is presented as the goal of the main action.

So the structure is:

• закончили ... с тем чтобы согласовать

This is similar to English:

• finished ... in order to agree/finalize

The infinitive works especially naturally when the people doing both actions are understood to be the same or left unspecified in the same way.

A more explicit finite-clause version would be possible in other contexts, for example:

• ...с тем, чтобы они согласовали...

That version makes the subject of the second action more explicit.

This is a question of aspect.

• согласовать = perfective
• согласовывать = imperfective

The perfective infinitive is used because the sentence refers to a completed result: the goal is not just to be in the process of coordinating something, but to bring the agreement/approval to completion.

So:

• согласовать = to get it agreed/finalized
• согласовывать = to be agreeing/coordinating, to work on agreeing

In purpose constructions, Russian often prefers the perfective infinitive when the goal is a single completed outcome.

Окончательный расчёт is the direct object of согласовать, so it is in the accusative case.

But both words are masculine singular, and расчёт is inanimate. For masculine inanimate nouns, the accusative singular looks exactly like the nominative singular.

So:

• nominative: окончательный расчёт
• accusative: окончательный расчёт

That is why the form does not visibly change.

If the noun were animate, the accusative would often look different.

Not necessarily just a mathematical calculation.

Расчёт can mean different things depending on context, including:

• calculation
• estimate
• settlement
• payment settlement
• final account

In business, financial, or administrative contexts, окончательный расчёт often means something like:

• final settlement
• final accounting
• final calculation/figure

So even if the basic dictionary meaning is calculation, the real sense may be broader and more practical.

Yes, absolutely.

A less formal version would be:

• Вычитку закончили, чтобы согласовать окончательный расчёт.

That would sound more neutral and conversational.

Very roughly:

• чтобы = neutral, common
• для того чтобы = a bit more explicit, still common
• с тем чтобы = formal, written, official

So the original sentence is not strange, but it belongs more to a formal register.

Yes. The standard pronunciation is расчёт, with ё.

In actual Russian writing, however, ё is often replaced by е, so you may also see:

• расчет

Even when written with е, native speakers still know it is pronounced расчёт from context.

This is very common in Russian spelling. For learners, it helps to remember the dictionary form with ё when possible, because it shows both:

• the correct pronunciation
• the stressed syllable

So in careful learner-friendly spelling:

• расчёт

But in real texts:

• расчет is also extremely common.
