The Malaysian government has spent 280 million ringgit ($A93 million) so far in the search for flight MH370, which disappeared more than two years ago, the Transport Ministry says.
The amount covered costs until the end of February, the ministry said in a written reply to a query from the parliament.
The underwater search for the missing flight has covered 86,752 square kilometres, it added.
The ministry did not say how much Australia and China have spent to locate the missing aircraft which disappeared on March 8, 2014, nearly an hour after it took off from Kuala Lumpur International Airport.
The aircraft, with 239 people on board, remains missing but was believed to have crashed in the southern Indian Ocean.
So far only a wing part, which was discovered on the French island of Reunion last year, has been confirmed to be part of the plane.
Two further pieces of debris found in Mozambique were "almost certainly" from the missing plane, the Australian government said last week.
