Different trendline types and which one you should use

There are different types of trendlines in Google Sheets, and each gives a different perspective of how your chart moved over a period of time and of how it will move over the next period of time.

Linear trendline

A linear trendline literally means a straight line of your trendline. It gives the simplest perspective of how the data moves over time and the easiest trendline most people can comprehend.

Although this might be the simplest, it might not cover a better understanding if you want to deeply analyze your data or when the rate of changes fluctuate, change too quickly, increases exponentially, and other complicated conditions.

Exponential trendline

An exponential trendline is the best type of trendline you can use for data when the value increases or decreases at a higher rate over time. It is usually useful to see the growth of a population or anything else that increases rapidly like the pandemic.

Polynomial trendline

A polynomial trendline is best used for data that fluctuates. If you want to see a short-term gain or loss between periods of time or track your expenses and see when you spend the most money, this is the trendline type you want to use.

Logarithmic trendline

A logarithmic trendline is usually used to show whether the growth rate of the data increases constantly or not. If it isn’t, it will show a rapid rate change at first but then equalizes. When used to show pandemic growth, it points out when the cases rise rapidly and when they slow.

Power series trendline

A power trendline is used to see measurements at the same rate. It is similar to the exponential trendline but is used differently, for example, the acceleration of a car.

Moving average trendline

A moving average trendline is used to smoothen the curve on a chart to show the trend pattern more clearly and to forecast long-term trends. In finance, it’s usually used in technical analyses for stock indicators, smoothening out prices by showing average prices that are always updated.


Trendlines when showed visually are easy to understand, but the functions behind them might be more difficult to grasp. Google Sheets has the feature to make that easier, with more options to visualize them.
