I'm working on sort of an early-stage idea for a personal budgeting product. So far, its main feature is going to focus on answering a single question: how much runway do I have? I wrote something rudimentary like this years ago when I adopted my first child, and it helped me make it through the rough financial patch(es) that followed with my sanity in-tact.
The question is, then, is just answering the one question enough of a value proposition? I don't think it necessarily is, so I'm trying to build on the idea to get people to the point of wanting to commit the time to enter the data/credentials the engine will need to make accurate predictions.
YNAB has a little feature called 'Age of Money' which I guess is like a reverse way of thinking about a runway. Maybe worth looking at?
In terms of the question asked — what level of friction people will put up with in order to get that prediction is interesting. I put a lot into my personal budget in order to get a crystal clear picture, so something that can provide even a vague idea for lower effort is bound to have some appeal. Depends on how the data gets in I guess?
