Everyone thinks you need to make $500k/year to retire early. You don't. You need to understand one number: your savings rate.

Here's the math that changed how I think about money:

If you save 50% of your income, you can retire in ~17 years. Regardless of whether you make $40k or $400k.

Why? Because your savings rate determines two things at once:

• How much you're investing (building your nest egg)

• How much you actually need to live on (your real expenses)

The higher your savings rate, the smaller the gap you need to fill with investments.

The FIRE formula is dead simple:

• Annual expenses × 25 = your FIRE number

• That's the portfolio you need to live off 4% withdrawals forever

So if you spend $40k/year → you need $1M.

Spend $30k/year → you need $750k.

Cut $500/month in expenses → you just shaved 3+ years off your timeline.

Most people focus on earning more. That helps. But the fastest lever is spending less — because it attacks both sides of the equation.

I built a free FIRE calculator and community to help people run these numbers for themselves. No BS, no courses to sell — just the math and a group of people actually doing this.

If you've been thinking about financial independence but don't know where to start, this is the starting line.
