First job, first 401k, first real paycheck. The decisions you make in the next 12 months have more impact on your long-term wealth than almost any decision you'll make later. Not because the amounts are large. Because time is compounding right now.

This page covers personal finance fundamentals that apply regardless of your view on Bitcoin or fiat currency.

This page covers US-specific accounts and tax law. Outside the US? The priority order is the same; the account names differ (ISA in the UK, TFSA/RRSP in Canada, Super in Australia, etc.).

THE SHORT VERSION

You have income now. Maybe a first real job, maybe a raise that made things feel different. Open a Roth IRA. Contribute to your 401k up to the match. Build a 3-month emergency fund in a high-yield savings account. Save 15% of take-home minimum. Everything else is detail. The compounding window is open and it doesn't reopen if you skip it.

Start here

Three pages, in order. Read them before opening any account.

1 · THE FRAMEWORK

The order of operations

Before picking investments, know the sequence: emergency fund, employer match, high-interest debt, IRA, full 401k, taxable.

2 · THE EARLIEST ACCOUNT

Open a Roth IRA at Fidelity, step by step

The single best financial move under 30 if you qualify. Tax-free growth for the next 40+ years.

3 · THE FOUNDATION

How to actually budget, fixed-first

Not a spreadsheet. A system that works on irregular income, with one automatic transfer doing 90% of the work.

Your most important tools

401k Match Optimizer

Are you leaving free money behind? Most under-contributors lose more in match than they save in cash flow.

Compound Interest Calculator

See what starting at 25 vs 35 actually costs across the same retirement number.

Savings Rate to FI

How your savings rate today determines when you have options, not when the calendar says you can retire.

Common questions

Do I pay off student loans or invest first?

If your loan rate is under 6%: invest up to your 401k match, then tackle the loans. Above 6%: aggressive payoff first. Always capture the match. Debt-type breakdown →

Should I open a Roth IRA or Traditional IRA?

Almost certainly Roth. You're likely in the lowest tax bracket you'll ever be in, so paying taxes now means tax-free withdrawals later. Open a Roth IRA →

How much of my paycheck should I save?

Minimum 15% of take-home. More if you want options before traditional retirement age. Savings rate → FI calculator →

What should I invest in?

FZROX in your Roth IRA to start. Total US market at zero expense ratio. Add international and bonds later as the balance grows. Index fund explainer →

When should I buy Bitcoin?

After you have an emergency fund, no high-interest debt, and are contributing to your 401k up to the match. Then: small, consistent DCA. Bitcoin is a long-term position, not your first move. Bitcoin for beginners →
