Localization could be important too, for broader adoption - not just for currency display but (most importantly) the kinds of investments available and tax rates vary a lot. A minor thing is that the 'default' values for % return and inflation are also different in different places
Good point. In addition to customizable income tax brackets, another idea I've been mulling over is a custom investment type with more controls to model a wider variety of investment vehicles. Perhaps I could add more templates as well, and show/hide some based on the localization settings.
Yes custom investment types! Up in Canada I have access to a registered retirement fund (tax-deferred, like a 401k but not as closely tied to employer) and a tax-free savings account (for untaxed growth), and I couldn’t figure out how to model monthly contributions to both out of a single salary stream.
Being able to fund both (and then in retirement, set a max annual withdrawal from the tax-deferred account before withdrawing from the tax-free) is to me an important bit of modelling that I couldn’t figure out how to get sorted in 15-20 minutes.
