Перерасчёт сделают вне зависимости от расчётного периода.

This is a very common Russian pattern: the indefinite-personal construction.

Сделают literally means they will do/make, but in sentences like this, Russian often uses 3rd person plural without naming who they are. In English, we often translate this more naturally as:

• They will recalculate it
• The recalculation will be done
• They’ll make an adjustment

So here сделают does not mean a specific group of people is important. It just means that someone responsible will do it.

Because сделать перерасчёт is a very common official and administrative collocation.

Russian often expresses actions in two ways:

• with a verb: пересчитать = to recalculate
• with сделать
  • noun: сделать перерасчёт = to make/do a recalculation

In formal, bureaucratic, billing, or legal language, the noun-based version often sounds more natural.

So:

• Пересчитают = more directly they will recalculate
• Сделают перерасчёт = more official/formal: they will carry out a recalculation

Перерасчёт means recalculation, adjustment after recalculation, or sometimes revised billing/charge depending on context.

It comes from the verb пересчитать / перерассчитать meaning to count again, to recalculate, to revise a sum or amount.

In practical contexts, перерасчёт is often used for:

• utility bills
• salaries
• taxes
• benefits
• payments
• service charges

So it is not just mathematical recalculation in an abstract sense; it often means a financial or administrative adjustment.

Literally, вне зависимости от is something like:

• outside dependence on
• not depending on

Naturally in English, it means:

• regardless of
• irrespective of
• independent of

So the phrase вне зависимости от расчётного периода means:

• regardless of the billing/calculation period
• irrespective of the accounting period

This is a fixed formal expression and is very common in official writing.

Because the preposition от requires the genitive.

The full phrase is:

• вне зависимости от + genitive

So:

• расчётный период = nominative
• расчётного периода = genitive

The adjective and noun both change because adjectives agree with nouns in case, number, and gender.

Here is the pattern:

• расчётный период → nominative singular
• расчётного периода → genitive singular

Расчётный период usually means billing period, accounting period, or calculation period, depending on context.

In everyday administrative language, it often refers to the period used to calculate:

• a bill
• a payment
• a charge
• a benefit
• some official amount

So although расчётный comes from расчёт (calculation), in real-world usage расчётный период is often best understood as the period used for billing or calculation.

Yes. In normal Russian writing, ё is often replaced by е, especially in printed or official texts.

So you may see:

• перерасчёт / перерасчет
• расчётного / расчетного

Both spellings are commonly encountered in real life, although ё is more precise because it shows the correct pronunciation.

Pronunciation:

• перерасчёт → stress on the final syllable
• расчётного → stress on чё

This is useful for learners because if ё is written as е, the stress may be less obvious.

Сделают is perfective future from сделать.

That means the sentence presents the action as:

• a single completed action in the future
• something that will be carried out

Compare:

• делают = they do / are doing
• сделают = they will do, they will complete

Here the perfective aspect fits well because the sentence is about the result: the recalculation will be performed.

Yes. Russian word order is flexible.

The original sentence:

• Перерасчёт сделают вне зависимости от расчётного периода.

A different order could be:

• Вне зависимости от расчётного периода перерасчёт сделают.

Both are grammatical. The difference is mainly in emphasis:

• starting with Перерасчёт highlights the recalculation itself
• starting with Вне зависимости от... highlights the condition regardless of the billing period

In official written Russian, both would sound natural.

Yes, definitely.

Several things make it sound formal or bureaucratic:

• перерасчёт
• вне зависимости от
• расчётный период
• the unnamed сделают construction

A more conversational version might sound simpler, depending on context, for example:

• Пересчитают независимо от периода.
• Перерасчёт сделают независимо от того, какой это период.

But the original sentence is exactly the kind of Russian you would expect in official notices, contracts, service information, or billing explanations.

Russian has no articles, so перерасчёт can mean either a recalculation or the recalculation depending on context.

You infer it from the situation:

• if the recalculation has already been mentioned, English may use the recalculation
• if it is being introduced for the first time, English may use a recalculation
• in official notices, English often drops the article or restructures the sentence altogether, for example: Recalculation will be made regardless of the billing period

So the Russian sentence itself does not mark this distinction directly.
