How to Use This Calculator

  1. Enter consumer spending (C).
  2. Enter private gross business investment (I).
  3. Enter government expenditures (G).
  4. Enter exports and imports to compute net trade balance (X - M).

The Mathematical Formula & Variables

GDP = Consumption + Investment + Government Spending + (Exports - Imports)

Step-by-Step Worked Example

Scenario: C = $19.5T, I = $4.8T, G = $4.9T, Exports = $3.1T, Imports = $4.05T.

  1. Net Exports = $3.1T - $4.05T = -$0.95T (Trade Deficit).
  2. GDP = 19.5 + 4.8 + 4.9 - 0.95 = $28.25 Trillion.

Result: $28.25 Trillion GDP
