In this article, you'll learn about the annualized return and how it's calculated in Composer.

**Where will you see an annualized return in Composer?**

In your library of symphonies

**What is the step-by-step calculation?**

Let's go through the calculation of the annualized return step-by-step for a symphony backtest. Here's how we do it:

- Compute the cumulative percent return of the symphony for the time between the first and last date in the backtest
- Add one to that value
- Raise that result to the (252/N) power, where N is the number of trading days in the backtest
- Subtract 1 from that result
