National accounts or national income accounts show economic flows among economic units at the macro level. These flows include production of goods and services which in turn leads to income payable to factors of that production, disposition of that income, saving and investment of economic institutions. This also includes economic activities dealing with the rest of the world, especially export and import of goods and services.
Moreover, the national accounts as the whole system will also include investment in financial and intangible assets and capital stocks including changes in stocks caused by various factors.
Quarterly Gross Domestic Product on the expenditure side (QGDE) is compiled by using the concept and methodology recommended in the United National System of National Accounts (UNSNA). Calculation on the expenditure side measures only the expenses on the final goods and services. Estimation Methods of QGDE at current prices include (1) Quarterly Private Consumption Expenditure, (2) Quarterly Government Consumption Expenditure, (3) Quarterly Gross Fixed Capital Formation, (4) Quarterly exports and imports are estimated by the direct method using quarterly data from the Bank of Thailand and (5) Calculation of Change in Inventories.
The formula is:
QGDE = C + I + G + (X-M) + D Stock
Where C = Private Consumption Expenditure
I = Gross Fixed Capital Formation
G = Government Consumption Expenditure
X-M = Net Export of Goods and Services when
X = Export of Goods and Services, M = Import of Goods and Services.
Quarterly Gross Domestic Product by the expenditure side has been estimated from the first quarter of 1993 to the second quarter of 1998 and will be carried out further to the current quarter. Previously, the classification of Quarterly Gross Domestic Product using fixed weighted volume measures by the expenditure side follows the Central Product Classification (CPC). After updating the compilation to Chain Volume Measures, the classification on the expenditure side is updated to Classification of Individual Consumption According to Purpose (COICOP). COICOP can be compared and linked to CPC and the CPC can be compared and linked to the International Standard Industrial Classification (ISIC) used in QGDP estimated by the production side and also to the Harmonized System used in imports and exports classification.

Estimation of QGDE in real terms
Thailand quarterly GDP comes in three stages:
GDP is also reported in seasonal adjustment figures which reflect the real changes in production and expenditure in each quarter as the seasonal effects are got rid of.
