Exponential Growth Calculator

EXPONENTIAL GROWTH CALCULATOR

A calculator for performing various calculations relating to exponential growth.

Select the calculation from the options below.

1. What will a value grow to after a given period of time at a certain percentage growth rate?

2. What percentage growth rate did a value grow at (or what rate is required) to reach a certain value in a given period of time?

3. How long will a value take to double at a particular percentage growth rate?

4. What will a value grow to if it has doubled a given number of times?

5. How many times will a value double to reach a certain value?

6. How long will a value take to grow to a given multiple at a given exponential growth rate? Or: How long will it be before a renewable resource such as solar energy is fully exploited if consumption is growing at a constant percentage growth rate?

7. How long will a non-renewable resource last if it is being consumed at rate which is growing at a constant percentage?

8. What will the total cumulative consumption be over a given period of time if consumption is growing at a constant percentage growth rate?

A compact version of the calculator presents all options on a single page.

MORE OR LESS

The strategies for addressing global environmental issues are clear: Efficiencies must be improved, personal consumption reduced and renewable energy embraced. But have environmental advocates really got it right. Or are we being led up the garden path.

More or Less explores the fundamentals of consumption and uncovers some basic truths that are... well... rather inconvenient.
