Figures revealed in EIA
Government promoted the TT and Festival of Motorcycling at a loss of almost £1 million last year.
The breakdown was revealed in the first part of a wide-ranging economic impact assessment by the Cabinet Office.
Commissioned in the wake of the Vision Nine debacle, the exercise should determine exactly how much motorsport generates - or loses - for the Manx economy.
Businesses and organisations from all sectors have been asked to submit evidence.
Now we know what the event costs government, based on different departments' expenditure at the 2017 TT and Festival of Motorcycling.
This covers items including helicopters and emergency medical care, prize and appearance fees, and upkeep of the roads.
Among the key figures are an additional half a million pounds spent on extra policing across the four weeks, and £60,000 profit turned over by the Villa Marina.
When all income and costs are taken into account, the two events were determined to have cost government just over £950,000 last year.
