Increase to or increase in

Hi all, I wonder if I can change “INCREASE TO” in this sentence by " INCREASE IN " . I can’t distinguish between " TO" and " IN" .Whether this would transfer meaning of sentence or not . Thank in advance

The combination “increase to” is followed by a value, usually a percentage, while “increase to” is followed by a unit such as “price”, “size”, “value”, etc.

Please let me know if this makes sense.

First the easy one.

Over the past two years the department has increased in size.

This is correct. You can not change the preposition.

Our gross margin increased to 24%.

This is also correct, and you can not change the preposition. But this one is a little trickier.

The 24% was not the percent of increase. Gross margin is always expressed as a percentage. So the 24% is the actual margin, not the percent increase. This affects the proposition.

For example if the previous gross margin was 16% and now it is 24%, that is an increase of 50%.

50% of 16% = 8%
16% + 8% = 24%

So there was an increase in gross margin.
There was an increase of 50% to 24%.

This terminology is more of a mathematics convention than an English convention. The difference between increase of and increase to causes confusion even among native English speakers.

We could combine the two;
“An increase in gross margin to 24%.”

And, looking at a similar case:
“This is an increase of 3% over last year.”

The report uses the word increase as a verb and the preposition ‘to’ is correct.
When increase is used as a noun, we use the preposition in.
If the level (like the height of water level in a dam) of something is meant, we may say an increase in the water level by one foot, or the water level increased to another foot’.
