Forecast your cash, retirement, and investments — and see exactly when you might run out.
This isn't a budgeting app, a wealth manager, or a tax advisor. It's a straightforward forecasting tool that takes your real numbers and shows you where you're headed — clearly and honestly.
A forward-looking forecasting tool for real financial decisions — not generic advice, not expensive subscriptions.
See your daily balances months or years into the future. Know before you overdraft.
Know when your savings may run out — based on your numbers, not industry averages.
Model investment growth, withdrawals, and returns with your own customizable assumptions.
Clear tables and projections — no spreadsheets, no jargon, no financial expertise required.
Unlike tools that rely on generic rules of thumb like the "4% withdrawal rule" or industry averages, Know Your Money builds projections entirely from the numbers you enter — your actual savings, your actual spending, your actual timeline. The result is a forecast that reflects your life, not a statistical average.
