but they dont match all of your money, after you hit that matching amount the % of their match goes down.
my company contributes 1% no matter what, the first 3% 1:1 and the last 2% 1:2 (so if you put in 5% they put in 5%, but if you put in 4% they put in 3.5%) but once you get beyond that the % contributed thats 'free' goes down (at 5% you double your money, at 10 your 1.5x example is valid, at 15% its 1.33, this works up to the 19500 limit)
if you are already seeing that full match patricks math is giving you an example of ADDITIONAL benefit to uping your contribution, not the benefit of your TOTAL contribution
