The fastest way to stop being broke is to start measuring. You can't improve a number you don't know. Most people couldn't tell you their net worth within $10K. Most people don't know how long it'd take their savings to double. Most people guess. Operators measure.

These five tools cover the math that runs the wealth-building game. Nothing here is gated. Nothing is sent to a server. Your inputs and your history live in your phone's browser, nowhere else. Clear your browser data and it's gone.

🔒
Privacy by default. Every number you enter stays on your device using localStorage. Nothing is uploaded, sold, or shared. You can wipe everything from the controls at the bottom of each tool.
TOOL 01

The Net Worth Tracker

Add up everything you own. Subtract everything you owe. That's it. The number is uncomfortable for most people. That's the point. Track it every month. The arrow direction matters more than the absolute number.

Assets — what you own

TOOL 02

The Compound Calculator

Einstein supposedly called compound interest the eighth wonder of the world. He probably didn't say it. The math is wondrous anyway. See what consistent monthly investing does over 10, 20, 40 years. Watch where the line gets steep.

TOOL 03

Your FIRE number.

Financial Independence, Retire Early. The number that, if invested, throws off enough every year to cover your life — without you ever working again. The 4% safe withdrawal rate comes from the Trinity Study. It's the closest thing to a "freedom formula" finance has.

TOOL 04

Your Money Habits scorecard.

Twelve questions across four dimensions. Be ruthlessly honest. The score isn't to make you feel good or bad — it's to show you the one dimension where most of your improvement is sitting. Re-score in 90 days.

TOOL 05

The Inflation reality check.

Cash in a savings account isn't safe — it's slowly leaking value. Inflation is the silent tax. See what your nest egg actually buys in 10, 20, 30 years. This is why "I'll just keep it in cash" is a position, not a non-position.

Use one tool weekly. Track the change. The number that matters most is the one that's moving in the right direction every month. Bookmark this page — the tools are most useful when you can pull them up in the moment.
