Economic Growth

Quarter Growth Index

<math>\Large QGI = e^{\left(\frac{\ln{\left(\frac{G_E}{G_S}\right)}}{n}\right)} </math>

• <math>G_S</math> is the GDP at the start of the time period
• <math>G_E</math> is the GDP at the end of the time period
• <math>n</math> is the number of quarters from start to end (4 quarters per year)

Annual Growth Index

<math>\Large AGI = QGI^4</math>

• 4 is the number of quarters in a year.

Annual Percent Growth

<math>\Large APG = (AGI-1)\times{}100</math>

Aggregate Formula

<math>APG = (e^{\left(\frac{\ln{\left(\frac{G_E}{G_S}\right)}}{n}\right)^4}-1)\times{}100</math>
