16 lessonsWhat is investing, really?
Investing is putting money to work so it can earn more money over time. Here is the plain-English version, with no jargon.
Read lesson →Stocks explained without the jargon
A stock is a tiny piece of ownership in a real company. Here is how that ownership actually makes you money — and how it can lose money too.
Read lesson →Bonds 101: the IOU you can buy
A bond is a loan you make to a government or company. They pay you interest, then give you your money back. Here is how that actually works.
Read lesson →ETFs vs. mutual funds: what is actually different
Both bundle many investments into one product. The differences are in how you trade them, how much they cost, and how taxes work.
Read lesson →Why index funds quietly won
An index fund owns the whole market — or a big slice of it — and charges almost nothing. Most professional stock-pickers cannot beat it. Here is why.
Read lesson →Risk and reward: the trade-off you cannot escape
Higher potential return always comes with higher potential loss. Anyone who tells you otherwise is selling you something.
Read lesson →Diversification: the only free lunch
Spreading money across many investments reduces risk without reducing expected return. It is one of the few things in finance that is genuinely free.
Read lesson →Compound growth: why early money is worth so much more
Compounding is interest earning interest on itself. Over decades, it is the single most powerful force in personal finance.
Read lesson →Dollar-cost averaging: the lazy way that often works
Investing the same amount every month removes the need to time the market. It also reduces regret, which matters more than people think.
Read lesson →Asset allocation: the one decision that matters most
Your mix between stocks, bonds, and cash explains the vast majority of your portfolio's behavior. Get this rough mix right, and the details barely matter.
Read lesson →What is a brokerage account?
The basic financial container that holds your investments. How it works, what makes a good one, and why it's not the same as a bank account.
Read lesson →Market orders vs. limit orders
When you buy or sell, you choose the order type. Pick the wrong one on a volatile stock and you can lose real money on the spread.
Read lesson →Expense ratios: the silent killer
A 1% fee sounds tiny. Compounded over 30 years, it can eat one-third of your final balance. Here's why fees matter so much.
Read lesson →Dividends: when companies pay you to own them
Some companies share their profits directly with shareholders. Here's how dividends actually work and why they're not free money.
Read lesson →Stock splits: making expensive shares accessible
When a stock gets too expensive, companies divide each share into multiple smaller shares. Mostly cosmetic, but worth understanding.
Read lesson →Good debt vs. bad debt
Not all debt is equal. Here's the simple framework for thinking about which debts to attack first and which can wait.
Read lesson →Banking & Savings
10 lessonsHigh-yield savings accounts (HYSAs)

Read lesson →Certificates of deposit (CDs): the predictable cousin
A CD is a savings account where you agree to lock the money up for a set time in exchange for a guaranteed rate. Useful in some situations, ignored in others.
Read lesson →Treasury bills (T-bills) for beginners
Short-term loans to the U.S. government, considered the safest dollar investment in the world. How they work and where to buy them.
Read lesson →Emergency fund: the unsexy thing that saves you
Cash set aside for surprises is what keeps a job loss or medical bill from becoming a financial catastrophe. Build it before you invest aggressively.
Read lesson →Checking vs. savings: the right setup
Most people use these wrong. Here's the simple structure that maximizes your interest while keeping your daily money easy to access.
Read lesson →Credit unions vs. banks: what's the difference?
Credit unions are nonprofits owned by their members. They often pay better rates and charge lower fees. Here's the trade-off.
Read lesson →I-Bonds: inflation-protected savings
A government savings bond whose interest rate adjusts with inflation. Useful for medium-term savings, with some annoying restrictions.
Read lesson →Money market accounts vs. money market funds
Same name, very different products. One is a bank account, one is an investment. Here's how to tell them apart.
Read lesson →How banks actually make money
Understanding the bank business model helps you understand why your savings rate is what it is, and why banks fight so hard for your checking account.
Read lesson →Mortgages 101: what you're actually signing up for
A mortgage is the largest financial commitment most people make. Here's how the loan actually works, what the payment really covers, and what to compare.
Read lesson →Retirement

An employer-sponsored retirement account with tax benefits and, often, free money from your company. The mechanics, in plain English.
Read lesson →Roth IRA vs. Traditional IRA
Two retirement accounts you open yourself, with the same contribution limits but very different tax treatment. The choice depends on your tax rate now versus later.

How the program works, when you can claim, and why claiming early is one of the most expensive financial decisions Americans regularly make.
Read lesson →Backdoor Roth IRA: when you earn too much

Read lesson →What to do with your 401(k) when you leave a job
Four options, very different consequences. Most people pick wrong by default and pay for it for decades.
Read lesson →Taxes
5 lessonsCapital gains: short-term vs. long-term
Selling an investment for more than you paid creates a capital gain. How long you held it determines how heavily it is taxed — sometimes by a huge margin.
Read lesson →Tax-advantaged accounts at a glance
Different account types in the U.S. get different tax treatment. Knowing the menu is half the battle in personal finance.
Read lesson →Marginal vs. effective tax rate
The difference everyone confuses. Knowing this is the difference between making smart tax decisions and making panicked ones.

A neutral, plain-English explanation of cryptocurrency — what it is, what makes it different, and what to think about before owning any.
Read lesson →Annuities: what they are and why most people don't need them
Insurance products that pay a stream of income. Sometimes useful, often oversold by commission-driven salespeople. Here's how to tell the difference.

Glamorous, mysterious, and mostly inaccessible. Here's what hedge funds actually do — and why their average performance might surprise you.

These markets exist, and some have real returns. They're also illiquid, opaque, and full of people trying to take advantage of you.
Read lesson →Behavior

Read lesson →Lifestyle creep: the silent wealth killer
Why people who get raises don't always get richer. The pattern most professionals fall into without noticing.
