GDP consider the current value for measurement of GDP called current market value. GDP used by every country to measure their economy, currently USA is the largest economy having GDP of 13.13 trillion dollars. GDP often measure in monetary terms rather then quantity, aircraft produce by USA and aircraft produce by china are not counted as same in GDP because their monetary value differ. Aircraft of USA might cost $80000 and china aircraft $40000 in this scenario GDP of USA is higher than china.

GDP Formula

GDP = consumption + gross investment + government spending + (exports − imports)

OR
GDP = C + I + G + (X-M).

Gross word is used because depreciation is not subtracted form the final value of all goods and services produce by the country. Less the amount depreciation form GDP is called net domestic product. Double counting problem may increase the value of commodities which reflect the GDP. For example, two companies are involve in car production, one company only supply tires for the car and second company manufacture the car , if the value of tires is already included in GDP then it should be subtracted from the car total cost.
