Hypothetically: ROI Tracker

What if $1,000 grew 10% a year for 20 years? Hypothetically answers before you finish typing. There's no calculate button — every digit you change redraws the whole curve live. DRAG THE CHART. Scrub across it to read your balance at any point in time. Every period you cross taps back, and milestones tap harder. You feel the timescale without looking away from the number. NUMBERS THAT ROLL. Values travel to their new total like an odometer instead of snapping. Same answer, better to watch. FOUR INPUTS, ONE SCREEN. A starting amount. A rate — percent or fixed dollars, positive or negative, so you can model a loss as easily as a gain. How often it compounds: trading day, day, week, month or year. And an optional recurring deposit on its own schedule. TRY TO BREAK IT. Put in 40% per trading day over twenty years. The number keeps up — cents, then millions, then billions, then scientific notation. Nothing overflows, nothing rounds to nonsense. 1W TO 20Y. Jump from one week to two decades with a tap. Same inputs, redrawn instantly. PRO. Terminal is free. The Pro purchase adds Vault (navy and gold), Ledger (paper and ink) and Arcade (pixel font, all caps), and removes ads for good. No subscription, ever. No account, no sign-up. The free version shows a short ad when you open the app, never while you're using it, and none at all for your first two days. Hypothetical — not a forecast. Nobody knows what markets will do. This shows you what the math does.
