- You must have drawn the short straw here. Good luck.
- The first item you mentioned was investment growth rate. I would like to be able to associate a growth rate with every investment asset that I have. So, if I have three accounts and each account has two positions, I would like to have six different rates that I can use, one for each position. Of course there are practical limitations here. I might suggest six, and maybe no more than ten. I adopt a lazy portfolio so I do not have many positions. I just moved from three to four.
- The second item you mentioned was taxes. I know all about taxes, right? You guys need to make the call here. Taxes bring lots of complexity but honestly any worthy tool needs to address income taxes, and that means both federal and state.
- Someone mentioned RMD’s. You need to think about the presentation here. In my mind, RMD’s and other IRA transactions are only tax issues. Otherwise, they are no different than moving money from your savings account and your checking account. Obviously, you would not be calculating the RMD, only providing a space for the user to enter an amount.
- You are already providing the ability to enter Social Security. The big question for the user is what numbers to use. That is on the user, not Tiller.
- You need to consider withdrawal strategies. The three I see are based on spending needs, maximum spending, and fixed percentage withdrawals.
- Someone mentioned Portfolio Visualizer. Very sophisticated, all of which I love. They have lots of great tools there but I suspect most of it is beyond the scope of your project.
- What is the new projected rollout date?
- Finally, I save the best for last. I have mentioned NewRetirement.com many times on this community but have never received much traction. I am sure Tiller has been listening and has looked at their product. If not, go there right now. This is what your are trying to replicate. I like and use their product. No harm in looking at their tool for ideas, presentation, etc. (Enough said…this is where that little man on my shoulder tells me to shut up and I actually listen to him.)
