He banked an £18.75m dividend from his company DB Ventures last year – up from £10.2m in 2016.
But he's unlikely to be helping his wife out much, given that he's about to realise his long-held dream of owning his own football club. His Major League Soccer club – nicknamed Beckham United – is due to be launched in Miami tomorrow.
The prices of about 200 lines have been slashed on the website of Victoria's fashion label.
A black floor-length corset dress, originally priced £3,250, is now just £975. A £2,250 cashmere coat is now £675 and a £1,595 fitted curve cami dress is £479. Many outfits are still available in all sizes, showing they have not been as popular as hoped.
That is despite the firm getting a boost from Meghan Markle, who wore a Victoria Beckham cashmere sweater in the official photoshoot to celebrate her engagement to Prince Harry. The £690 garment sold out.
But Victoria herself no longer has the same ability to drive sales.
A two-piece she wore in New York last October is among the reductions, slashed from £1,800 to £541.
Fashion industry analyst Eric Musgrave said: "Nobody wants to discount by this amount. It damages the brand credibility and upsets people who have paid full price.
"All companies need to clear out their unsold stock. But this shows Victoria Beckham has clearly over-ordered – or that she is producing designs that haven't proved popular. The question remains how long are her backers willing to sustain that."
The company was founded in 2008 and employs 180 people. Last year it attracted a £30m boost from outside investors.
An insider at Victoria Beckham Ltd insisted the clear-out was a normal end-of-season sale, adding that the company "is in a strong financial position, with long-term backing".
