I wouldn’t worry about the cost of kids. Based off what you are doing now, you would be fine regardless. If you want to engage in a fun exercise, run the numbers on what you would be looking at from a retirement savings perspective if you were able to max out until age 55. Then do a second one where you are able to max out for the next couple years and then have to be only at your employer match for about 10 years (then back to maxing out). I think you’re going to find that the numbers look good regardless. The only difference is in the first scenario, you’re going to be giving hundreds of thousands or even millions of dollars to your nieces and nephews someday.
