If you mean what is the difference between the expressions "Exactly!" and "Spot on!" then there is practically no difference. There can be a slight difference in usage in if you say "exactly!" you are probably pleased with what the other person has just said, because you are in agreement. In comparison, "spot on!" doesn't have to be agreement, it can just indicate that something the other person has said is accurate. Examples: A: I don't get why they don't provide forks at this restaurant. How are we supposed to eat the food? B: Exactly! That's why i always bring my own fork when I come. (B is in agreement with the sentiment A has expressed) B: What Is 6÷2(1+2)? A: 9 because you have to divide 6 by 2 first, and then multiply by the sum of 1 + 2. B: Spot on. A lot of people get tricked by this math puzzle (B is simply stating that A is accurate. There is less of an emotional component of agreement involved).

Both can Describe Like "RightThere "

Although there are some elements of a shared meaning, they are usually used in context very differently. "exactly" is used as both a reaction response for confirming and as part of a full sentence for wanting more detail. ---> someone asks "so I ALWAYS have to tell my boss when I want to leave work?" and the response "exactly". ---> someone asks "what exactly do you do for work?". "spot on" is definitely very British, you're right about that, and is used as a reaction response to a good job having been done, indicting accuracy and to confirm. ---> someone says "I got all of the paperwork filed, so we can go home early" and the response "spot on" ---> someone says "your report is spot on" ---> someone asks "so I need to be at the interview 30 minutes before it starts?" and the response "spot on". Both examples of "exactly" are very commonly used but regarding "spot on", it is only used in the UK and mostly for the denoting accuracy (the 2nd example). I hope this helps.

Hi Yusuke, Yes, “spot on” sounds much more British, but it is also used in fewer contexts than “exactly”, because it’s an interjection that can sometimes be an adjective phrase, while “exactly” is an adverb. The main context where the two overlap is as a reply to someone’s deduction or conclusion.
