Money words, in plain English
15 August 2026
Most financial words are ordinary ideas wearing a suit.
That is not an accident. A lot of the industry has a quiet interest in you not quite following, because a person who does not fully understand what is being offered is easier to sell to, and less likely to ask the awkward question.
So here are the words you actually run into, in plain language. Not alphabetically, because nobody reads a glossary from A to Z. Grouped by where you meet them, so you can jump to the bit that confused you.
Words about money coming in
Gross pay. What you earned before anything is taken out. The big number on the offer letter.
Net pay. What actually lands in your account after tax and deductions. This is the only one of the two you can spend, and it is the number to plan with.
Pay cycle. The stretch between one payday and the next. Most money advice quietly assumes a calendar month, which is wrong for anyone paid weekly, fortnightly or irregularly. Your month starts when you get paid, not when the calendar says.
Income. Money coming in. A moment, not a state.
Cashflow. The movement of money in and out over time. Income is what arrives; cashflow is the pattern. Two people on identical salaries can have completely different cashflow, and it is the one that decides whether the last week of the month hurts. There is a longer piece on building one.
Surplus. What is left after everything that had to go out has gone out. The number that actually decides whether you are getting anywhere.
Words about what you have
Assets. Things you own that have value. Cash, savings, investments, a pension, property, money other people owe you.
Liabilities. What you owe. Loans, card balances, anything outstanding.
Net worth. Assets minus liabilities. One number for your whole financial position, and the one that actually measures progress, because unlike your bank balance it cannot be flattered by borrowing. How to work yours out.
Liquid. How quickly something turns into spendable money without losing value. Cash is perfectly liquid. A money market fund is close. Property is not liquid at all, which is why someone can own a lot and still be unable to pay for a car repair this week.
Capital. Money you have set aside to be put to work rather than spent. Your principal, before any growth.
Words about spending
Fixed costs. The ones that arrive whether or not you do anything. Rent, insurance, subscriptions, loan repayments.
Variable costs. The ones that move with your choices. Food, transport, going out.
Discretionary spending. The part you genuinely choose. Useful to name, because most people overestimate how much of their spending is discretionary and then blame themselves for a shortfall that was structural.
Lifestyle inflation. Your spending quietly rising to match a rising income, so a raise leaves you no better off. The most common reason a good income can still feel broke.
Subscription creep. Small recurring charges accumulating until they are a significant fixed cost nobody decided on. The audit that fixes it.
Safe to spend. What is genuinely yours to use today, after the bills still coming and the money you have set aside, divided across the days until you are paid again. Not a budget, and not a limit somebody imposed. Just what is actually left.
Words about saving
Emergency fund. Money set aside for the unknown. A job loss, a hospital visit, a car that dies. Its whole job is to stop an emergency turning into a debt. How much, and where to keep it.
Sinking fund. Money set aside for the known. A rent renewal, school fees, an annual insurance bill. Different from an emergency fund because you already know the date. Why the predictable bills are the ones that wreck people.
Pay yourself first. Moving money into savings when you are paid, rather than saving whatever survives the month. Sounds like a slogan. Is actually the whole difference, because what survives the month is usually nothing.
Savings rate. The share of your income you keep. More useful than the amount, because it still means something when your income changes.
Words about borrowing
Principal. The amount actually borrowed, before interest.
Interest. The cost of using someone else's money, or the payment for lending yours.
APR. Annual percentage rate. What a loan costs over a year including fees, which makes it the honest number for comparing two loans. A "small monthly fee" can be an enormous APR.
Flat rate versus reducing balance. Two ways to charge interest on the same loan. Flat rate charges on the original amount for the whole term even as you pay it down; reducing balance charges only on what is still owed. A flat rate quoted as ten percent can cost close to double what reducing balance at ten percent costs. If a lender will not tell you which one it is, that is your answer.
Collateral. Something the lender can take if you do not repay.
Default. Failing to keep up repayments, at which point the terms usually get worse.
Debt to income. Your monthly debt payments as a share of your income. Lenders use it to size you up, and it is worth knowing your own.
Buying on credit. Taking goods now and paying later. Ordinary and often sensible in business. It only becomes a problem when nobody is keeping a proper record of who owes what, which is the point at which a debtor quietly becomes a gift.
Words about investing
Return. What you get back beyond what you put in, usually as a percentage per year.
Compounding. Earning a return on your returns, so growth accelerates as long as you leave it alone. It also runs in reverse on debt, which is why an unpaid balance can grow frighteningly fast. The mechanic, explained properly.
Inflation. Money losing purchasing power over time. It is why cash sitting still is not actually standing still, it is slowly shrinking.
Real return. Your return after inflation. If an account pays eight percent and inflation is ten, your real return is negative, and the account is losing you money while appearing to pay you.
Risk. The chance of losing money, or of the outcome differing from what you expected. Not a dirty word. Every option has some, including keeping everything in cash.
Volatility. How much a value swings around. A volatile investment is not necessarily a bad one, but it is a bad one for money you will need soon.
Diversification. Not putting everything in one place, so a single bad outcome cannot take all of it.
Portfolio. Everything you hold, taken together. The point of the word is that individual holdings matter less than the whole.
Yield. The income something pays out, as a percentage. Distinct from growth in what it is worth.
Treasury bill. A short term loan to a government, repaid with interest on a fixed date. Usually the lowest risk option available in a given country. How they work, using Ghana as the example.
Money market fund. A pooled fund holding very short term, low risk debt. Often where people park money that needs to stay reachable but should not sit idle.
Mutual fund. A pooled fund where many people's money is invested together and managed for a fee.
Unit price. What one share of a fund costs. Your holding is your number of units times the unit price, which is why the value moves even when you have not added anything.
Capital gain. Profit from something rising in value, only realised when you actually sell.
Cost basis. What you originally paid. Your gain or loss is measured against it, so it is worth recording at the time rather than reconstructing later.
Words that sound like something they are not
These are the ones that cost people money.
"Guaranteed returns." Almost nothing is guaranteed except government debt in its own currency, and even that is guaranteed in name, not in purchasing power. Attached to a high percentage, the word guaranteed is a warning rather than a reassurance. The full list of tells.
"Passive income." Usually neither. Most of what gets sold under this name requires either significant money upfront or continuous work, and the phrase is doing a lot of quiet lifting.
"Interest free." Check where the cost went. It is often in the price, the fees or a penalty that starts the moment you are a day late.
"Up to." As in up to twenty percent returns. Up to includes zero.
"Risk free." No. Lower risk exists. Risk free does not, and anyone using the phrase is telling you something about themselves.
The habit that matters
You do not need to memorise any of this. What is worth building is a much smaller habit: stop nodding along.
The next time someone uses a word you do not fully follow, ask what it means, right there. Not later, not privately afterwards. Anyone offering you something legitimate will explain it happily and will not make you feel slow for asking. Anyone who gets impatient, or answers with more jargon, has just told you something far more useful than the definition would have.
That one question, asked out loud, will protect more of your money over a lifetime than any single thing on this list.
If you use Wealthpadi, a lot of these stop being abstract, because you are looking at your own numbers instead of examples. Your net worth is your assets minus what you owe. Your safe to spend is what is genuinely left today. Your holdings show what you actually own and what it is worth right now. The words are easier to hold onto when they have your own figures attached to them.
Put this into practice
Wealthpadi turns habits like these into something automatic. Track your money, set goals, and watch your net worth grow. Free to start.
