Net Worth Percentile at 30 to 34

Median net worth for 30 to 34 is $88,631, up from $31,470 five years earlier. That is close to a tripling in five years, the sharpest proportional jump of any bracket in the data.

The average for this group is $258,075, which is about 2.9 times the median. That is the narrowest average-to-median gap of any age band, and it makes the thirties the one decade where the average is almost usable.

Nothing else in the dataset moves like this. The median roughly triples between the late twenties and the early thirties, then takes another fifteen years to merely double again. Compounding is part of it, but most of it is simply that this is when incomes rise fastest while the assets that will later dominate, chiefly home equity and retirement accounts, start accumulating in earnest.

It also means the bracket you are compared against changes underneath you very quickly. Someone who was comfortably above median at 29 with $40,000 can be below median at 31 without having gone backwards at all. The bar moves faster than most people's balances at this age.
