Long-term wealth is decided by a handful of mechanics: how much you save, the return you earn, the interest you stop paying, and the tax wrappers you use. This hub gives each mechanic a proper model — retirement accounts with contribution limits and tax treatment, debt payoff simulated month by month under both major strategies, and savings tools that show inflation quietly taxing idle cash.
If debt comes first, run the avalanche vs snowball comparison and the credit card and student loan payoff tools to get a debt-free date. Then build the base: an emergency fund sized to your life, and a net worth statement you can re-measure quarterly. Investors can project compound growth, test a Roth conversion, compare Fat and Lean FIRE targets, and find the Coast FIRE point where contributions can stop and compounding finishes the job.
All projections are estimates based on the returns and rates you enter — markets do not move in straight lines. The tools show their formulas and scenario tables precisely so you can test pessimistic assumptions, not just hopeful ones. Nothing here is personal financial advice; use the numbers to plan and to have better conversations with a qualified adviser.
