Straightforward explanations for those at the start of their financial journey.
You do not need to learn everything at once. Start with the basics, then use the calculators to test the numbers that matter to you.
A sensible starting point is to understand the difference between short-term cash needs and longer-term investing. Money you may need soon is usually treated differently from money you can leave alone for years.
Once that makes sense, the calculator becomes more useful. You can test a monthly amount, change the growth assumption, and see how much difference time makes.
Different investment types behave differently. The right mix depends on goals, timeframe, risk tolerance and personal circumstances.
Cash is usually the most stable and accessible option. It can be useful for emergency funds and short-term goals, but over long periods inflation may reduce its buying power.
A share represents partial ownership of a company. Shares can grow in value and may pay income, but their prices can move sharply up or down.
Bonds are loans made to governments or companies. They may pay interest and return capital at maturity, but they are not risk-free.
A fund pools money from many investors and invests across a collection of assets. Funds can be actively managed or designed to follow a particular market or asset class.
An exchange-traded fund is a type of fund that trades on an exchange. It can give exposure to a broad market, sector, region or asset class.
Property can mean owning physical property directly or investing in property-related assets. It may provide income and potential growth, but it can be less liquid and may involve higher costs.
Commodities include things like energy, agricultural products and precious metals. Prices can be driven by supply, demand, inflation, currency moves and global events.
Alternative assets can include private investments, digital assets, hedge-fund-style strategies and other specialist areas. These can be complex, higher risk and harder to value.
These are the ideas most new investors should understand before comparing projections.
Compound growth happens when growth is earned on both the original money and any previous growth. Over long periods, this can make time one of the most powerful parts of an investment plan.
If an investment grows from 1,000 to 1,070 in year one, future growth may apply to 1,070 rather than just the original 1,000.
An annual percentage return is the growth or loss over a year, shown as a percentage. A 6% annual return on 10,000 would be 600 before considering fees, tax, inflation or market movement timing.
A projected annual return is only an assumption. Real returns vary and can be negative.
Volatility means prices move up and down. A long-term investment can still have difficult months or years. Volatility is normal, but it can be uncomfortable.
Diversification means spreading money across different investments, regions, sectors or asset types so that your outcome is not dependent on one single holding.
Asset allocation is how your money is split across investment types, such as shares, bonds, cash and other assets. This mix can strongly affect risk and potential return.
Your time horizon is how long you expect to invest before needing the money. Longer timeframes may allow more time to recover from market falls, but they do not remove risk.
Adding money regularly can help build the habit and reduce the pressure of trying to invest at the perfect time. The amount, consistency and timeframe all matter.
Inflation means prices rise over time. A portfolio may grow in nominal value while its real buying power grows by less after inflation.
Fees reduce returns. Even small percentage differences can matter over long periods, especially when money is invested for decades.
Liquidity means how quickly and easily something can be turned into cash. Some investments are easier to sell than others.
Some investments focus on paying income. Others focus on long-term growth. Some do both. The right balance depends on your goal.
Risk tolerance is how comfortable you are with the possibility of losses or large swings in value. It is personal and can change over time.
The annual return assumption has a big effect over long timeframes. This is why projections should be treated as examples, not promises.
| Concept | What it means | Why it matters |
|---|---|---|
| 3% annual growth | A cautious example | May be useful for conservative modelling |
| 6% annual growth | A moderate example | Often used as a middle projection assumption |
| 9% annual growth | A higher-growth example | May involve more volatility and uncertainty |
| Custom growth rate | Your own assumption | Useful for testing different scenarios |
The calculator allows custom annual growth assumptions, but no assumption should be treated as guaranteed.
A simple checklist to consider before investing. This is not personal advice, but it can help structure your thinking.
I understand that investments can fall as well as rise.
I have considered whether I need an emergency fund first.
I know my rough timeframe and why I am investing.
I understand the difference between cash, shares, bonds and funds.
I understand that fees, inflation and tax can affect real results.
I know the calculator is only modelling assumptions, not predicting the future.
