Pick a question, enter three numbers, and see two paths compared side-by-side over 50+ years — so you stop guessing and start deciding.
Choose the decision you're facing. We'll build the comparison for you.
Retiring early? Career change? Big purchase? Pick the decision you're facing and we'll set up two scenarios to compare.
Your dashboard shows two trajectories side-by-side over 50+ years. See exactly where the paths split and by how much.
Adjust any assumption, add life events, or create more scenarios. One-off expenses never permanently inflate your trajectory.
Every chart updates in real-time as you adjust assumptions.
Each scenario uses its own CAGR, expense growth, and retirement year while sharing a common configuration baseline. See how different decisions ripple across your entire financial timeline.
Overrides are non-compounding — a one-off expense spike won't permanently inflate your trajectory.

I spent years running my financial projections in a sprawling Excel workbook. Every time I wanted to answer a simple question — “What if I retire five years early?” or “What if the market returns less than I expect?” — I had to duplicate sheets, rewire formulas, and cross-check everything by hand. So I turned it into an app where you pick the question you're trying to answer, and the comparison builds itself.
