What These Tools Do

Most people max out their 401(k) and stop there. But there's a tax-efficient order to fill retirement accounts: employer match first, then HSA, then IRA, then remaining 401(k), then brokerage. The Investment Optimizer does that math for you in seconds. When your portfolio drifts from its target, the Rebalancer tells you exactly what to buy and sell. And the Net Worth Tracker turns your annual financial checkup into a 5-minute exercise with year-over-year charts.

These tools are for anyone managing retirement accounts, investments, or a household budget — whether you're just starting out or decades into your career. No financial jargon required.

Everything is free, with no signup and no ads. Your data never leaves your browser — all calculations run locally, and your inputs are saved to your device so they're there when you come back.
