@tbslee If you are under 50 and just want to max out the TSP evenly over the year, Table 1 shows you how much to contribute. Some people who are under BRS want to contribute a little more each month to get more money in the TSP earlier. The problem with that is if you contribute too much you can max out before the end of the year and lose out on matching contributions. Table 2 shows the maximum you can contribute and still ge the full match all year. Tables 3 and 4 have the same purposes as Tables 1 and 2, respectively, but they are for people who are 50 and older and can make catch-up contributions. Basically, here is who should use each table.
Under 50 and want to max out the TSP, contribute at least the amount in Table 1.
Under 50 and want to make sure you get the match all year, contribute no more than the amount in Table 2.
50 and older and want to max out the TSP, contribute at least the amount in Table 3.
50 and older and want to make sure you get the match all year, contribute no more than the amount in Table 4.
