About the Economic Impact Calculator
Economic impact analysis estimates the total economic activity generated by an investment or event.
It's the number every government and developer needs.
Formula
Total Impact = Direct × (1 + Indirect + Induced)
- TI
- — Total Economic Impact
- D
- — Direct Investment
- I
- — Indirect Impact (supply chain)
- In
- — Induced Impact (spending)
How to use this calculator
- 1
Enter direct investment
The initial investment or spending.
- 2
Enter indirect multiplier
Supply chain effects (e.g., 0.5).
- 3
Enter induced multiplier
Employee spending effects (e.g., 0.3).
Example calculations
Factory economic impact
A $100M factory investment with 0.5 indirect and 0.3 induced multipliers.
Total = $100M × (1 + 0.5 + 0.3) = $180M.
- Total economic impact:
- $180M
- Indirect impact:
- $50M
- Induced impact:
- $30M
The $100M factory creates $180M in total economic activity.
Interpreting your results
Economic impact multiplies the initial investment through supply chains and employee spending.
Multipliers vary by industry and region. Manufacturing multipliers are typically higher.
