Up to now vs until now [closed]

I want to say that something is currently completed, in a percentage.

Which sentence is correct?

Up to now the job has been completed by 10%

or

Until now the job has been completed by 10%

Thank you in advance

In my (British) English, the only ordinary way of saying this is so far.

The phrases up to now and until now are slightly stilted, and if they were used by a native English speaker I would infer some special meaning, that something significant has changed or is about to change. Perhaps that the way of measuring the amount is different, or that the job is getting much harder.

Up to - used for various points and measures to describe a certain segment (not necessarily time. E.g. fill the container up to 500 ml mark)

Until/till - used to describe a lapse of time before a certain point in time (E.g. we waited until sunset - i.e. waiting is the lapse between now and sunset)

For your example sentence, I would suggest:

• Currently/at the moment, the job has been completed up to/by 10%.
• 10% of the job has been completed so far.

It seems that rather than a period of time, your sentence alludes to reporting the status at a precise point in time, which is present/now.

My belief is this: Unless something is against grammar or long-held idiom, all is good, as long as the meaning is clear.

The two sentences above make sense to me. Since I am no grammarian, I don't know if it goes against any established rules.

If it were I, I should more likely say, "As of now, 10% of the job is completed".
