College, student loans, and your first paycheck.

The money skills nobody teaches before you need them

North-star rule of thumb

$5/week from age 20 → $40,000+ by 65

Starting at 20 vs starting at 30 is the difference between a six-figure outcome and a five-figure one. Time, not amount, is the cheat code.

The overview

Money decisions between 18 and 25 compound for the rest of your life. The Roth IRA you open at 22 has 43 years to compound by the time you're 65 — almost 7 doublings. A 5-year delay costs almost half of that. So the goal here isn't to optimize every dollar; it's to not miss the moves that matter most.

We cover the moves that matter most: how to read your first paystub, what a W-4 actually does, the order to attack student loans, when income-driven repayment beats standard, when a Roth IRA beats a 401(k) for someone in a low tax bracket, and the case for an emergency fund before any 'real' investing starts.

Below: the cluster articles, the Student Loan Reality Check widget, the $5 Time Machine for the under-25 audience, and the parents-and-teachers guides for anyone teaching this to a teenager. The Education section has the full lesson tracks for ages 10-17 and 18-24.

What we don't do: pretend college is or isn't worth it across the board. It depends on the major, the cost, the alternative, and the loans. The cluster articles below walk through that math without pushing a side.
