While Vladimir Putin's official salary is understood to be around $190,000, the Russian President's net worth remains a mystery, but some estimates have it in the billions.
The former KGB agent's official pay package is said to include a 148-square-metre apartment in the centre of Moscow, three official cars - two of them Soviet-era models - and his official residence.
However, there are significant discrepancies between what Putin draws as 'salary' and his actual net worth.
Putin is believed to be the covert owner of several oil and gas companies, private jets, a fleet of helicopters and luxury cars, expensive watches, and a yacht worth $135 million.
Putin's critics have often claimed he could well be the world's richest man with assets totalling up to US$200 billion ($271 billion).
Elon Musk's net worth of US$234 billion makes him officially the world's richest man, but there appears little doubt Putin enjoys a life of opulence way beyond the means of any state head in the world.
Here's a look at some of the most expensive things he owns.
Haute watch assortment
He has often been photographed sporting high-end luxury watches, including Rolex and Breguet Marine, with some worth more than his annual income.
His watch assortment includes a US$470,000 A Lange & Sohne Tourbograph with crocodile skin strap, a white gold Patek Philippe Perpetual Calendar worth US$61,000; and a US$11,000 Blancpain Leman Aqua Lung Grande Date.
Black Sea mansion worth $1.4 billion
He is rumoured to be the owner of a stunning 17,651-square-metre mansion situated atop a cliff that overlooks the Black Sea.
Known as 'Putin’s Country Cottage', it is the largest private residence in Russia.
'The Palace', as is it often referred to, is believed to have a marble swimming pool lined with statues of Greek gods, frescoed ceilings, a 2,508 square-metre guest house, spas with traditional hammams, an amphitheatre, ice hockey rink, casino, nightclub and much more.
The lavish interiors, complete with Louis-XIV-style sofas, US$500,000 worth of dining room furniture, and a US$54,000 bar table, have reportedly been decorated by an exclusive luxury Italian brand called Citterio Atena.
The mansion is maintained by a 40-member staff at an annual budget of US$2 million.
The Kremlin denies Putin’s ownership of the property and maintains it belongs to a wealthy businessman.
Incredible fleet of cars
Putin owns as many as 700 high-end cars, from a limousine to extreme off-roaders.
He has an Aurus Senat Limousine priced at US$1.2 million, a Mercedes ML 500 worth US$46,000, a Lada Vesta Sedan that costs US$11,000, a GAZelle Limousine specially made for him worth US$160,000, and a Lada Niva four-wheel drive worth US$25,000 among others.
His current presidential state car is the Aurus Senat limousine, equipped with many life-saving, offensive, and defensive measures, and is built to the Federal Protective Service's standards.
Private jets and choppers
Putin is said to have a collection of 58 aircraft and helicopters, including a US$716 million plane called 'The Flying Kremlin'.
The plane features a golden toilet, believed to be worth a whopping $75,000.
Given his preference for helicopters over cars, he owns an unspecified number of Russian-made Mi8s, which come at a basic cost of US$4 million each.
Impressive collection of yachts
Aside from a rumoured collection of four yachts, each costing a small fortune to maintain, Putin was gifted a US$35 million Yacht by oligarch Roman Abramovich, owner of English Premier League football club Chelsea.
A BBC documentary claims Putin charges the expenses of maintaining the 57-metre Olympia yacht to the state, despote it being his own personal property.
But that's not all. He has another yacht worth US$100 million. It has 13 cabins that can accommodate 12 guests and 14 crew members and it apparently has the largest pool ever installed on a yacht.
