Money words, in plain language

Early payments go mostly to interest, later payments mostly to principal — even though the payment amount never changes.

Why it matters: It explains why year one of a loan barely moves the balance.

A yearly rate that folds in interest plus certain required fees, so two loans can be compared on closer to equal footing.

Why it matters: The advertised monthly payment hides the cost. The APR shows it.

An asset can be sold, rented, or can produce income: index funds, shares, property, a business. Value can go down too — an asset is not a guarantee.

Why it matters: Growing the asset side of your life is the whole point of owning more.

A regular investment account with no special tax treatment and no withdrawal age. You add money, then choose what to own.

Why it matters: It's usually the first door between deciding to own and actually owning.

Your monthly income against your monthly obligations and spending. Positive cash flow is the raw material for owning anything.

Why it matters: No cash flow, no decisions — only reactions.

When what you own grows, that growth starts growing too. $1,000 that gains 7% becomes $1,070 — and next year the 7% works on the larger number.

Why it matters: It is the only reason a paused $350 purchase can matter thirty years later.

Balance divided by limit. Using $2,000 of a $10,000 limit is 20% utilization.

Why it matters: It's one of the fastest-moving inputs to a credit score.

Cars, electronics, gear. You may genuinely need it — just don't file it mentally next to the things that grow.

Why it matters: Most 'investments' people defend are actually this.

Spreading what you own across many companies, sectors, and regions so a single bad outcome doesn't decide your result.

Why it matters: It lowers the odds that a single mistake becomes the whole story.

You buy the same dollar amount at regular intervals regardless of price — more units when prices are low, fewer when high.

Why it matters: It removes timing from the decision, which is where most people stall.

Money kept accessible and boring — usually a few months of essential expenses — so a surprise doesn't become new debt.

Why it matters: It's what keeps one bad week from undoing a year of good decisions.

Many workplace plans add a percentage of what you put in, up to a limit — a dollar-for-dollar match doubles your own contribution.

Why it matters: It's the rare case where ownership starts with money that isn't yours yet.

A basket of investments you can buy or sell during market hours at a live price, often tracking an index.

Why it matters: It's the most common wrapper people actually use to start owning.

A percentage of your balance taken each year to run the fund. 0.03% is about $3 per $10,000; 1.00% is about $100.

Why it matters: Fees compound too — just not for you.

Instead of picking companies, you buy a fund that tracks a broad list of them. Fees are typically low and you own a slice of everything in it.

Why it matters: Ownership doesn't require stock picking. This is the unglamorous default.

Expressed as a percentage of what you owe. A 24% card rate means the balance grows by roughly a quarter of itself each year if untouched.

Why it matters: High-rate debt compounds against you faster than most investments compound for you.

A balance you're obligated to pay: a card balance, car loan, student loan, mortgage. It has a size and a cost (the interest rate).

Why it matters: Owing less is half the sentence. Liabilities are what you're shrinking.

A raise arrives and expenses expand to match it, so the extra income never reaches ownership.

Why it matters: It's the most common reason earning more doesn't feel like progress.

It covers interest and a sliver of principal. Paying only the minimum can stretch a balance across years.

Why it matters: Minimums are designed for the lender's timeline, not yours.

Add up your assets, subtract your liabilities. The number can be negative early on — that's a starting point, not a verdict.

Why it matters: It's the one scoreboard that moves when you own more and owe less.

The real price of a purchase isn't only the sticker. It's the sticker plus everything that money can no longer do.

Why it matters: The ownership calculator exists to make opportunity cost visible before you decide.

A named account that receives the money from purchases you decided against, so a pause turns into a deposit instead of vanishing.

Why it matters: A skipped purchase only becomes ownership if the money physically moves.

Ownership is having a claim on something productive — a share of a business, a fund, equity in a home. Unlike a purchase, it can still be worth something years from now.

Why it matters: Every decision on this site is a swap: consumption you use once, or ownership you keep.

On a loan, principal is the balance before interest. On an investment, it's the money you contributed.

Why it matters: Paying interest feels like progress. Only principal shrinks the debt.

Part math, part temperament: how far your investments could fall before you'd sell at the worst possible moment.

Why it matters: The best plan you'll abandon is worse than the decent plan you'll keep.

You contribute money you've already paid tax on; qualified withdrawals later are tax-free. Contributions are capped and rules apply.

Why it matters: Same ownership, better long-run tax math for many people early in a career.

What you've already paid is gone regardless of what you do next. The only useful question is what the next dollar should do.

Why it matters: It keeps people paying for things they stopped wanting years ago.

A pause is a set delay — an hour, a day, a week — added on purpose before a discretionary purchase, so the decision is made by you rather than by momentum.

Why it matters: It is the single step that turns consumption into a decision.

Employer contributions or equity grants often become yours over time. Leave before you vest and you forfeit the unvested part.

Why it matters: Ownership on paper and ownership in fact are not always the same date.

The size of the ups and downs over time. High volatility means bigger swings in both directions, not a guaranteed loss.

Why it matters: Ownership is uncomfortable sometimes. Knowing that in advance is the point.
