# My returns are wrong

The returns for your portfolio are always calculated using a time-weighted rate of return. This is to avoid distorting performance due to deposits or withdrawals.

Essentially to calculate the return for your portfolio, we calculate the return for each sub-period and then multiply these returns.

Please note: deposits affect the calculation of your returns! **For deep understanding check out** [**this article**](https://www.investopedia.com/terms/t/time-weightedror.asp#:~:text=The%20time%2Dweighted%20rate%20of,inflows%20and%20outflows%20of%20money)**.**

> *Example:*
>
> *Alice put in $1000 during the first month and gains 10%. She then decides to put in another $2000 and gains 5% during the second month. Her ending balance is $3255.*
>
> *Bob also put in $1000 at the same time and gained 10%. He then decided to take the profit and withdrew $100. During the second month, he gained 5%. His ending balance is $1050.*
>
> *Their end results are different***,** *yet the performance is the same. The returns should reflect that.*
>
> *So to calculate time-weighted rate of return, we just multiply (1 + 0.1) \* (1 + 0.05) - 1 = 0.155 or 15.5%*

If you still find that your returns are wrong, please send a message into the in-app chat describing your situation, we will check and correct everything.
