The corporation's register of external events has been released for the first quarter of 2022, revealing TV presenters' extra earnings made from their work outside the BBC.
Walker - who competed in Strictly Come Dancing last year - hosted two private events on a single day in February, each paying between £5,000 and £10,000.
Walker recently told BBC Breakfast viewers his decision to leave the show were not motivated by money.
The father-of-three said: "I've never ever been motivated by money in any job that I've ever taken, and even though I've loved working at BBC Breakfast and everybody who works on the show, this is a fantastic opportunity to work with a brilliant team at Channel 5."
Other presenters to have made money from hosting corporate events include newsreader Huw Edwards.
The 60-year-old presenter made over £25,000 hosting four separate events in March, on top of his salary of £425,000-£429,999.
Walker's fellow BBC Breakfast presenter Naga Munchetty, 47, made between £5,000 and £10,000 hosting an awards ceremony for the British and International Golf Greenkeepers Association this year.
Other BBC presenters to charge £5k-£10k per appearance include Newsnight's Kirsty Wark, 67, and BBC Radio 4 presenter Nick Robinson, 58.
The BBC began publishing a list of its stars earning £150,000 or more in 2017, at the request of the government. In 2021 it began publishing an additional register of staff earnings from external events.
Gary Lineker is currently the highest-paid star at the BBC, despite taking a pay cut. He topped the list for third year in a row in 2021 with a salary of £1,360,000-£1,364,999.
His last day hosting the morning show will be Tuesday 17 May before he moves to Channel 5.
The TV presenter competed in the 19th series of Strictly last year and finally left the BBC dance competition with professional partner Nadiya Bychkova in the quarter final after weeks of evading the dance-off thanks to votes from viewers.
Despite getting so far in the contest he chose not to take part in the live tour.
Before he joined the BBC Breakfast team Walker presented Football Focus on BBC from 2009 to 2021.
