It's not that good. I'm 1800+ too but I have 2800+ puzzle rating. So get good scrub.
Is a 2400 puzzle rating good?

honestly? its not that good
sike its really good cuz i absolutely suck at chess and 2400 is like 2x my puzzle rating and 3x my blitz rating lol

I am 1200 in chess.com and I can solve 2800 puzzles. On custom. My puzzle rating is 2500. I guess it is decent.

I do problems in another site, I struggle at 2300

I retired from doing rated puzzles because they became unpractical, and my rapid rating shot up +200 points from taking the break.
If you have a 2400+ puzzles rating, you should easily be able to reach 1800+ rapid rating provided you are ingraining proper technique and management skills.

I have 750 on rapid but 2455 on puzzles so if I play a lot more I could go up by a lot?
If your basic tactics are sharp, CCT technique and blunder checks are ingrained; 1500 rapid is the baseline from what I have witnessed from past training partners and students.

Puzzles rated is a bumpy ride , I reached 2700 a few weeks ago, now I’m back to just over 2400 ….. it’s worse than being on the “ Big Dipper “ it builds yer up , and then sucks yer back down again ! 😤

You can achieve any rating on chess.com or lichess from 100-3600 and it will only ever be a basic guide to one's chess abillity, you can't earn any title through online chess playing unless it's done through FIDE over the board events! We had a guy walked in our chess club we made him welcome, was quite full of himself ... I HAVE A RATING OF 1870, our club sec went on ECF website to check his name and over the board rating and came back not registered we asked him how he got his rating ... ON CHESS.GOM?!! anyway our chess is modest ECF. 126 (1608 Elo) he played him 2 games with no time limits and won both in under 30 moves, Mr I am 1870 rating said I only play quick play so a clock was provided and set at 5 minutes a game and our secretary won the first two games and his opponent abandoned the last game saying he was tired and left rather quickly?! SO WHAT ARE THE CONCLUSIONS... Seems quite apparent that these online ratings are evidently inflated compared to actual playing abilities over the board the ECF 126(1608) was clearly stronger in abillity than the Chess.com guy rated at 1870!!!
look at the distribution curve it tells you how many people are at the 2400 level on chess.com.
