Marc Anthony -- I'm Not as Rich as She Thinks ... But I'm Still Really Rich

Marc Anthony is SCOFFING at his ex-wife for daring to claim he made $60 million over the last 4 years. Marc says she's way off ... he only made a hair over $40 mil.

Marc filed new legal docs in his ongoing custody war with former Miss Universe Dayanara Torres, who claims she was forced to live in a crappy San Fernando Valley hovel with their 2 kids while he lives lavishly.

But Marc is putting things in perspective, laying out his finances in the docs -- obtained by TMZ. Marc says over the last 2 years he spends an average of $305K A MONTH.

It all adds up so fast. Marc says he's spent around $400,000 on domestic help over the last 2 years. We're guessing that doesn't include shelling out for JLo while she did "Maid in Manhattan."

And then there's $220k for auto leases, $1 million for a California home and another $700K for 2 New York residences.

Dayanara wants her monthly child support upped from $13K to $113K.
