The retired sportsman took home the hefty sum after his new company Seven Global LLP managed to make £8.6 million of profit in only seven months.
A source told The Sun newspaper: "There is no stopping Brand Beckham. Even though he has long retired from football David's empire keeps on growing. He is a savvy businessman and surrounds himself with like-minded people. The latest figures are staggering but it's no real surprise."
The figures come from the £3.8 million, which was paid to Beckham's DB Ventures and lifestyle company Global Brands Group Holding Limited, with the money thought to come from his successful collaboration with brands including clothing retailer H&M.
Elsewhere, David also managed to secure another £11.4 million in profit at his Footwork Productions company, which rakes money in for the use of David's name and his image.
It comes after the 41-year-old star admitted he isn't into lavish gifts and wants socks for Christmas.
He said: "Socks is always a good one. You know, I'm an Englishman so we - us Brits we love nice socks, so I've asked for socks this year. Victoria's list - nice pajamas. She loves some nice PJ's, comfy and cozy."
And despite his wealthy status, David much prefers to wear casual clothes like jeans, t-shirts and trainers rather than suits.
He added: "[I am a] very casual dresser. I love to wear smart suits and I like to feel smart when I go out for dinner but I also much prefer to wear jeans, T-shirts, trainers, boots, vintage boots and that's kind of how I dress every single day."
