Ye recently sat down with Nick Cannon for a segment on Nick's podcast, "Cannon's Class," and they started talking dollar figures, with Kanye boasting he's richer than Donald Trump.

Kanye says he burned through a ton of cash on his Sunday Service in 2019 ... with the $50 million being spread around for choir uniforms, flights, operas and all the other operating expenses that went with it.

At first glance, that number sounds way overblown.

However, remember ... Sunday Service traveled around the country last year, with stops at Coachella, Skid Row in Los Angeles, Houston, Howard University in D.C., the family home in Calabasas, his ranch in Wyoming, The Forum in Inglewood, Louisiana, Chicago, Ohio, Joel Olsteen's Lakewood Church and even Jamaica.

There were construction costs too ... for the Sunday Service on Easter at Coachella, bulldozers moved tons of earth to make a huge hill for the performance.

Ye says the cash was taken out of funds set aside for marketing his Yeezy shoes ... Kanye says he didn't need to spend all the marketing dough on the kicks -- Yeezy's sell themselves, he says -- so instead he used it to put on Sunday Service.

$50 million ... that's a lot of holy bread.
