Game context, not financial advice. This article explains how things work inside
Quidsmith, a personal-finance simulation game. The numbers are illustrative and the model is simplified for play. It is not personal financial advice. For decisions about your own money, speak to a regulated adviser.
Personal finance is buried in initials. Quidsmith uses the real ones, because that is what you meet on a bank website or a pension statement, but nobody is born knowing them. This is the plain-English key to every acronym and bit of jargon in the game.
You don't have to memorise these
Inside the game, finance terms carry a faint dotted underline. Hover or tap one and a short definition pops up, so the meaning is always a second away without leaving the screen. These glossary hints are switched on by default in Easy and the Tutorial, and off in the tougher modes where you have likely found your feet. You can turn them on or off for good under Accessibility at any time.
Accounts and tax wrappers
A "wrapper" is not an investment itself. It is a shelter you put investments inside so the taxman leaves them alone.
| Term | Stands for | What it means |
|---|
| ISA | Individual Savings Account | A wrapper that shelters savings or investments from UK tax. You can pay in up to £20,000 a year across all your ISAs combined. |
| Cash ISA | — | An ISA holding cash savings. The interest is tax-free, but it tends to trail inflation. |
| S&S ISA | Stocks & Shares ISA | An ISA holding investments (a fund or individual shares). Growth and dividends inside it are tax-free. |
| LISA | Lifetime ISA | An ISA with a 25% government bonus, meant for a first home or age 60. Take the money out for anything else and a 25% charge claws the bonus back. |
| GIA | General Investment Account | A plain, taxable investment account with no deposit limit. Where you invest once the ISA allowance is used up. |
Investments
| Term | Stands for | What it means |
|---|
| ETF | Exchange-Traded Fund | A single fund that spreads your money across hundreds of companies at once, so no one firm can sink you. The game's Global ETF is its main growth engine. |
| Gilt | — | A bond issued by the UK government. It pays a fixed yearly coupon and hands your money back at maturity. Steadier than shares, and the ballast in a portfolio. |
| Coupon | — | The fixed yearly interest a bond or gilt pays, quoted as a percentage of its face value. |
| Dividend | — | A share of company profits paid out to shareholders. Tax-free in an ISA; taxed above a small allowance in a GIA. |
Tax
| Term | Stands for | What it means |
|---|
| CGT | Capital Gains Tax | Tax on the profit when you sell an investment or a second property held outside an ISA. A tax-free allowance applies first, then 18% or 24%. |
| SDLT | Stamp Duty Land Tax | A tax paid when you buy property. Second homes and buy-to-lets carry an extra surcharge on top. |
| Section 24 | — | The rule that limits landlords to a basic-rate tax credit on their mortgage interest, rather than deducting it in full. It bites hardest on higher-rate taxpayers. |
| Marginal rate | — | The tax rate on your next pound of income (20%, 40% or 45%). It sets how much pension tax relief is worth to you. |
Property
| Term | Stands for | What it means |
|---|
| BTL | Buy-to-let | A property bought to rent out for income and long-term price growth, usually with a special mortgage. |
| LTV | Loan to Value | How much of a property is mortgaged rather than yours. A lower LTV usually earns a cheaper interest rate. |
| HMO | House in Multiple Occupation | A rental let room by room to several unrelated tenants. Higher yield, but more rules and more managing. |
| ERC | Early Repayment Charge | A fee for overpaying a fixed-rate mortgage beyond its yearly penalty-free limit. |
| Void | — | A stretch when a rental sits empty and earns nothing while its costs roll on. The hidden drag on rental yield. |
Pensions and later life
| Term | Stands for | What it means |
|---|
| SIPP | Self-Invested Personal Pension | A private pension you control and choose the investments for. Contributions get tax relief; the pot is locked until 57. |
| Drawdown | — | Taking an income from your pension pot in retirement by selling a bit at a time, rather than buying a guaranteed income. |
| Annuity | — | A product bought with a lump sum that pays a guaranteed income for the rest of your life. Sits outside your net worth. |
The economy
| Term | Stands for | What it means |
|---|
| CPI | Consumer Prices Index | The standard measure of inflation, how fast prices rise. It quietly erodes the real value of any cash you hold. |
| Base rate | — | The Bank of England's interest rate. Savings rates and mortgage rates move up and down with it. |
| Nominal vs real | — | A nominal figure is the headline number; a real figure strips out inflation to show what it actually buys. A £2m house in 65 years is a much smaller sum in today's money. |
