Is there an existing metric that computes the Total Return including dividends and net of costs?

Hi,

I am looking forward to understand how a pool of actively managed mutual funds yields benchmarked to three ETFs using LSEG Refinitiv's workspace. I want to download and personally go through the analysis, but I need to find the right metric to download first. I have three different questions: 1. The NAV is net of every type of expense that the investor occurs? 2. For distributing ETFs, where can i find prices that account for dividends distributed? 3. For actively managed and accumulating mutual funds, does the NAV already include fees and costs associated with the fund?

In other words, what data (the NAV?) should I download to compute a total return for Distributing, Accumulating ETFs and Actively managed accumulating funds?

Thanks in advance!
