According media sources his management had also negotiated a share of the eventual profits of the film. With The Karate Kid film taking more than $150m (£100m) at the box office, the young actor received another $2m(£1.3m) bonus.
The media estimate that other perks signed into Jaden's contract would have resulted in a payday of over $3m (£2m). As well as starring in the film he also sang the theme song 'Never Say Never' alongside teen superstar Justin Bieber.
Jaden's seven figure salary makes him by far the highest paid of any of the young actors currently in Hollywood. Although the film was released in 2010 when Jaden was 12 he had begun filming at the age of 10.
The young actor began his career with a small part in his father's 2006 film The Pursuit Of Happyness. With his youger sister Zillow they have forged out careers with the blessing of their parents Will and Jada Pinket Smith.
As well as acting Jaden has forged a career as a rap artist and his 10 year old sister had a No 2 hit in the UK with Whip My Hair. Like her older brother she has appeared in several films, most notably I am Legend, alongside her father.
