GDP Calculator
Calculate Gross Domestic Product using the expenditure, income or production method.
Tip: Nominal GDP doesn't account for inflation — use real GDP (at constant prices) for year-on-year comparisons. INSTAT publishes both.

About this digital tool
The GDP calculator works out Gross Domestic Product with the expenditure method: consumption, investment, government spending and net exports. Enter the values in billions, and see total GDP, net exports and the weight of each component as a percentage.
The formula is GDP = C + I + G + (X − M), where C is household consumption, I investment, G government spending, X exports and M imports. The tool also shows what percentage of GDP each component makes up, so you understand the structure of the economy. It is useful for economics students, for assignments and exams and for understanding macroeconomic reports.
How to use
- Choose the method (expenditure, income, production)
- Enter the components (C, I, G, X, M)
- Or enter the sector values
- See the total GDP
- Compare with previous years or other countries
Frequently asked questions
What does GDP measure?
GDP measures the total economic output within a country's borders in a period (usually a quarter or year). It includes consumption, investment, government spending, and net exports.
What is the difference between nominal and real GDP?
Nominal: at current prices (includes inflation). Real: at constant prices (removes the effect of inflation). E.g., if GDP rises 8% nominally and inflation is 3%, real growth is ~5%.
Does GDP measure well-being?
Not fully. GDP doesn't include: unpaid work (household), the informal economy (large in Albania, ~30%), environmental degradation, inequality, or quality of life.
What is the formula for GDP by the expenditure method?
GDP = C + I + G + (X − M). Add consumption, investment, government spending and net exports (exports minus imports).
