Mr. Money Mustache has a lot of really good advice that I find a lot of value from. However, I think Mr. Money Mustache underestimates the ease and impact of opportunities to grow income relative to cutting spending - especially if you're in (or can be in) a high-earning field like tech. Doubling your income will put you on a much faster path than cutting your spending a further 5%.
PredictionBook is really great for lightweight, private predictions and does everything you're looking for. Metaculus is great for more fully-featured predicting and I believe also supports private questions, but may be a bit of overkill for your use case. A spreadsheet also seems more than sufficient, as others have mentioned.

This is a good answer.
Not really an answer, but a statement and a question - I imagine this is literally the least neglected issue in the world right now. How much does that affect the calculus? How much should we defer to people with more domain expertise?
