Online Calculator or Software Advice - Portfolio Profit

[Guy Davis]

I know there are calculators for evaluating the initial rental purchase but I'm looking for advice on a calc or software that allows me to understand the profit/loss after the purchase and expenses to ensure I'm still on track and the investment is good.

Along with this, it would be nice if I could put my entire portfolio in a tool and it tell me my overall net worth or profit on the portfolio. Does anyone know an online calc or software that helps w this? Thanks in advance for your help!
