Adjustable assumptions—not market forecasts.
Converts effective annual return to a monthly rate; assumes end-of-month contributions. Fixed returns are for understanding compounding only—real investments fluctuate; results exclude fees, taxes, and inflation.
Different return assumptions change results sharply. Also test zero and negative returns—not only optimistic cases.
Put cash flow, net worth, and FIRE goals in one system.

Hello, I’m Yi Hang.
This site turns common questions about investing, options, and retirement cash flow into lessons you can follow step by step. Rather than only asking “how much can I earn?”, ask: what risk am I taking? What was this money for?
Our principles are simple: state assumptions clearly, separate income from total return, and put what you could lose on the same page.
