Calculating Average Annual Growth Rates

The Average Annual Growth Rate (AAGR) is often used to evaluate population growth or Christian growth rates. AAGRs are also useful to make projections about the number of years needed to reach a specific goal.

There are several ways to calculate Average Annual Growth Rates.

1. Tables found in the Church Growth Survey Handbook are useful to determine AAGRs (found in the Resource Download library, Training). However these tables have limits to precision. So you may wish to use a scientific calculator or a spread sheet to perform this calculation.
2. It is possible to use a scientific calculator or a spreadsheet to perform these calculations. The attached .pdf file explains how to configure a spreadsheet. The .xls file is a template that can be used. There are other similar spreadsheets in the Research Download library (tools).
