3 Numbers Jo Har Investor Ko Pehle Jaanna Chahiye | Paisa Lagao, Loss Mat!

The 3 numbers every person must know before they invest a single rupee

Most people open a brokerage account before they understand three basic numbers. That mistake costs them more than bad stock picks ever will.

The three numbers are: your monthly burn rate, your emergency fund runway in months, and your actual investment time horizon.

Without knowing your burn rate, you cannot size positions. Without runway, one bad month forces you to sell at the worst time. Without a clear time horizon, every market dip feels like a crisis instead of an opportunity.

I learned this the hard way. I was excited to invest before I had answered these three questions. The market taught me that excitement without foundation is just expensive impatience.

Start here before you start anywhere else.

What number did you figure out last — burn rate, runway, or time horizon?
