Simple and compound calculation
Content also available for tax entities or on our global site.Sharesight gives you the option to see your portfolio (and holdings) return either in Simple or Compound return calculation.
You can find this option under Performance calculation method in the Settings tab. This applies to both individual portfolio and consolidated view.
Simple vs compound return
This example illustrates the difference between these two calculations. Assume a portfolio has:
Year 1: $100,000
Year 10: $200,000
Time period: 10 years
The return look as below.
The simple return is straightforward. The portfolio value doubled in 10 years, therefore the total return is 100% with annual return of 10%.
The compound return, or compound annual growth rate (CAGR), uses the exponentiation symbol (^) to calculate how investment returns accumulate over time, accounting for the compounding effect of growth on prior gains.
Which one should you use
There is no right or wrong answer. In saying that, compound return is the industry standard. When a fund manager publishes the fund’s performance since inception, over a specific period, or benchmark against an index, they are all calculated in CAGR.
Same return for both calculation if measurement period is less than a year
If you calculate return over a 1-year period, simple return and CAGR will be the same because there’s no time for compounding to occur.
Consider the above example again. If the time period is 1 year instead of 10 years, both simple and compound calculation will show the same result of 100%.
For simple, it is [(200,000-100,000) / $100,000] * 100 / 1 = 100%
For compound, it is (200,000/100,000)^(1/1)-1 = 100%
