What Is GDP?

Gross Domestic Product (GDP) represents the total value of all final goods and services produced within a country during a specific time period (typically a quarter or year).

➡️ It reflects the size and health of a nation’s economy.
➡️ A rising signals growth; a declining signals slowdown or recession.

How Is GDP Calculated?

it can be measured through three major approaches:

1️⃣ Production Approach

GDP = Total Output – Intermediate Consumption
This method sums up the value added by all industries.

2️⃣ Income Approach

GDP = Wages + Profits + Rents + Interest + Taxes – Subsidies
This method looks at who earns from economic activity.

3️⃣ Expenditure Approach (most common)

GDP = C + I + G + (X − M)

Where:

• C = Consumer spending
• I = Business investment
• G = Government spending
• X = Exports
• M = Imports
