Why investing birthday money early matters
Most birthday cash disappears within weeks — absorbed into snacks, small toys, or forgotten in a drawer. The same money, set aside in a long-term investment account, quietly compounds in the background for the next 18 years. The earlier it starts, the more time it has to grow into something your child can actually use: a college fund, a first car, a down payment, or seed money for a first business.
How compound growth works for kids
Compounding is growth on top of growth. A $100 gift at age 1 earns returns. Next year, both the original $100 and last year's growth earn returns. Over 18+ years, this stacking effect quietly does most of the work — often turning total contributions into 2–4× their original value, depending on rate and time.
That's why the timing of a gift matters as much as the size. A modest amount given at birth can outperform a much larger gift given at 15.
