How long does it take to get to each benchmark, 1000, 1200, 1500, 2000, 2200?

Ok so lets take chess.com rating in consideration,

You should reach (if you are completely new to chess):

1200- 6 months 

1400- 1 year

1600 - 1.5 year

1800- 2.5 years

Note: This is the average, if you work very hard you can reach much faster obviously!

Rest I dont know coz I havent reached there yet

Here a 1800 = 1700 Elo and i do not think the average joe playing a few games per week will get to 1700 Elo in 2.5 years here.....maybe 4-5 if he is very talented of course!

1600 in 18 months? hehe i know many that have 1 year here  and are not even 1400 elo....

usually it take 1 year to get 100 points;of course some may get 300 in one year but they have a coach or they are really talented!

look at how many have a rating of 1600 here? not even 5%.

at 1440 here in rapid you are in the top 7.5%

even in the USCF only 35% are 1600 or above! and for 1700 it's 30% 

How is your USCF 2999?!

It took me about 10 years to reach 2200+, doing it mostly on my own.

(Though I did receive in-person coaching from an NM, for about 3 months, when I was a Class B player.)

You did very well!

That's simply not true.

For me I made 1600 after something like 1.5 years, and made 2200 (chess.com, my national rating is only 2130 peaked at 2170) in 5.5 years. 

You are way above the average! you are very talented and you worked very hard?

The average adult tournament player in the USCF is rated around 1400.12 janv. 2020

I have been playing chess competitively for 3 years and have a elo of around 1000-1100 I learned chess 5 years ago so I strongly disagree with this. This also applies to one of my friends. They have been playing for 2.5 years and is about 900

Play me and i will rate you?

I looked at one of your last game and you need to learn one opening with white! 

all depends how hard you work and how motivated u are.I learned the rules of chess 6 months ago and im 2000.Someone will never reach that while someone can do it in less time.All depends on u

I really don’t know sorry - I learnt how to play about two months ago - I am just over 1300 on chess.com all I know is I always lose against my step brother. 

i have 900 on chess.com, 1200 on first rating on lichess, 1300 on other username on lichess., 1230 on chesstempo. i think that chess.com is the hardest..i started in 7th month of 2020

prove it isnt because computers have proved it

Incorrect.

I assume your reasoning is along the liens of "computers beat humans because humans miss tactics, therefore tactics win" which is flawed for, off the top of my head, 3 reasons.

I think anything you want to "master" takes 7 years w/ some talent, interest and work. But even then, the more you know, the more you know how little you know...

it depends on the person, nothing else, but the person themselves

speedrun from 1100 to 2300 in two years on chess.com
