Some tools online offer the ability to see how many dividends are likely to come your way. For example, extraETF provides a tool where you can see what the dividends might look like based on an assumed growth rate (CAGR), a certain number of years, and asset gains.
What I haven’t seen so far is a tool that, starting from a portfolio, calculates the dividend growth based on an assumed CAGR and dividend yield, while also factoring in taxes. That’s exactly the kind of tool I’ve created.
