The comedian reunited with John Cleese, Michael Palin, Terry Gilliam and Eric Idle for ten sold-out reunion shows at London's 02 Arena in July (14) but Jones insists he barely saw any of his $1.3 million (£800,000) salary after tax was deducted and his ex-wife Alison Tefler took half, $640,000 (£400,000), in accordance with their divorce agreement.
Jones is now unsure if he can pay off the mortgage on his $4 million (£2.5 million) mansion in the capital's Hampstead neighbourhood, telling Britain's The Times newspaper, "I'm not sure. Maybe I can pay it off, maybe not."
He adds, "We each got £800,000 for the shows, but when I got divorced I agreed with my ex-wife that everything I'd done up to then (including anything related to Monty Python), up to the separation, we would split 50-50... so my share got halved to £400,000 and paying tax on it it's more like £200,000."
Jones and Tefler had two children. He is now married to Anna Soderstrom and they have a five-year-old daughter Siri.
