I've had individual access to Right Capital for 3-4 years now. You have to go through a Financial Planner that subscribes in order to have an account set up. I paid a one time fee of $100 and that was my only business with that planner. He no longer offers just software access alone but my access is supposed to continue for as long as he subscribes.
Is it better software than available for free on the 'net ? Yes, IMO. The ability to forecast taxes makes Roth conversion modelling a breeze, so it's easily worth what I paid for just that feature. It also allows modelling SS claiming, pension claiming, etc. that updates the entire report for each individual tweak. How much is it worth ? I dunno if I'd pay more than $200-$300 for access and I'm not a potential client for any other Financial Planner services. Usually it is used by the planner and reports are generated by them for clients as part of the service package. Be aware that a lot of planners aren't going to give you access to run your own scenarios, they will just provide reports they've set up. I don't know how highly I'd value reports generated by a CFP verses having access to use the software myself,.
Be aware that Right Capital software is customizable by the individual subscribing CFP and the front page of the software used by a lot of planners is just a custom entry page for their individual business. A lot of Financial Planning businesses will use Right Capital software but with the software name changed to make it look like the Planner has a proprietary product. The modeling engine behind the scenes is all Right Capital regardless.
Also be aware that the planner you gain access through will input their own forward guesses for market performance and inflation and your individual results with the software will reflect their projections while using their client access.
