How do investments earn you money?

How Do Investments Earn Money Personal Finance 15 Bitpanda Academy

There are many reasons why people want to invest their money and build wealth over the years: saving for a home, fulfilling a dream or for retirement provision. But what exactly does it mean to invest money? We clarify what options there are for investing money, compare the best investment types and explain whether it’s possible to invest money without risk.

  • Definition: An investment is a capital investment aimed at increasing your money over years through interest, returns, dividends or other earnings.

  • Investment types: Options for investing money include deposits in funds, ETFs, shares, property, bonds, cryptocurrencies, fixed‑term deposits or a current account.

  • Procedure: Create a budget, set financial goals, compare investment options and decide how and where you want to invest your money.

  • Risk diversification: Spread your capital across different asset classes, industries and regions to diversify your portfolio, offset losses and increase the stability of your investment.

What is an investment?

With an investment or capital investment you invest an amount for a certain period (usually several years) in order to increase it. This works through various investment types, for example via income in the form of interest, dividends or capital gains. Investments (for example shares, ETFs, other securities or fixed‑term deposits) differ depending on risk, return and liquidity. With some the invested money is tied up for several years, other investment types are more flexible.

How do you earn money through investments?

If you invest money with a well‑thought‑out strategy you can earn income. Because your invested capital yields returns over the years such as interest, return, dividends, capital gains or rental income. Through the compound interest effect you can build your wealth long‑term.

Depending on investment type, risk and term there are various income sources:

  • Interest: If you save your money in a fixed‑term or current deposit account you receive regular interest payments. The amount depends on term, the product and the current interest rate.

  • Return: If you invest for example in funds or ETFs you can benefit from price increases. If the value of your investment rises compared to the purchase price, a return is generated. It shows how much your invested capital has grown over time.

  • Dividends: Many companies distribute part of their profits as dividends to shareholders – usually once a year or quarterly. The profits however depend heavily on the market environment.

  • Capital gains: You receive a capital gain when selling assets. The prerequisite is that the sale price of the property or securities is above the original purchase price.

  • Rental income: Investors who invest their money in property can profit from rental income all year round.

Did you know? When you invest money there can be a compound interest effect. If you reinvest your earnings immediately your wealth grows not only linearly but exponentially through the effect. Especially with a long term the effect can significantly boost your return.

What are the best options for investing money?

Which is the best capital investment depends on various individual factors. Among the most popular options are:

  • Funds

  • ETFs

  • Shares

  • Property

  • Bonds

  • Current and fixed‑term deposits

  • Cryptocurrencies

Funds

Funds are an investment form in which you can invest in several securities at the same time. You acquire units in the fund and share in the performance proportionally. A fund manager takes on the selection, monitoring and adjustment of the contained securities. The aim is to utilise opportunities, minimise risks and achieve the most attractive return possible for you as an investor.

Opportunities:

  • Diversification: You invest your money across many investments which lowers risk.

  • Professional management: Experts handle the investment strategy.

  • Return potential: Through possible price gains you can achieve an attractive return.

Risks:

  • Costs: Actively managed funds usually charge higher fees than passive ETFs.

  • Market risks: Even a broadly diversified fund can lose value in economic fluctuations.

  • Dependence on management: The return depends strongly on the fund management’s performance.

ETFs

ETFs (exchange‑traded funds) work similarly to classic funds but are passively managed. In doing so an ETF follows the performance of an existing index – without a fund manager intervening. The composition of an ETF is always publicly accessible, because it follows a fixed index. That way your investments are also broadly spread.

Opportunities:

  • Broad spread: Even with small amounts you can invest in hundreds of stocks and lower your risk.

  • Low costs: ETFs generally have lower annual management fees than actively managed funds.

  • Long‑term return: Historically many indices achieve positive performance over several years. Note however that past performance is not an indicator of future performance.

Risks:

  • Fluctuations: ETFs also fluctuate, so short‑term losses cannot be excluded.

  • No guarantee: Since ETFs do not pay fixed interest your return depends on the index’s performance.

Shares

Shares are securities with which you acquire part ownership of a company. When you buy a share you become a co‑owner and can benefit from dividends. The value of a share is determined by supply and demand on the market and can change daily.

Nevertheless shares have been among the highest yielding investments for years, which also carry higher risk. Some expertise is therefore required. You should also be comfortable with short‑term price fluctuations.

Opportunities:

  • High earnings potential: Shares can bring above‑average returns via dividends over years.

  • Participation: As a shareholder you typically have voting rights and can attend general meetings.

Risks:

  • Price fluctuations: Stock markets react sensitively to economic, political or sector‑specific developments.

  • Total loss risk: If a company you invested in becomes insolvent you may lose your initial capital.

Property

Currently property is among the investment types considered relatively safe. With this investment form you can earn ongoing returns through rental income or benefit long‑term from capital gains if market value rises.

Compared with other investments property is regarded as low risk and inflation‑resistant. It therefore plays a role in long‑term wealth building and can be part of retirement provision.

Opportunities:

  • Regular income: Rental income can provide steady earnings over several years.

  • Value growth potential: In high‑demand locations high returns via price increases are possible.

  • Inflation protection: Tangible assets like property often retain value even in economically uncertain times.

Risks:

  • High initial capital: Acquisition usually requires a large equity share.

  • Liquidity risk: Property ties up capital that cannot be released quickly.

  • Management effort: Letting, maintenance and possible rental defaults can mean effort and extra costs.

Tip: If you want to benefit from the stability of property without buying a house or flat yourself, then property funds or property ETFs may be worth considering to diversify your portfolio.

Bonds

States and companies issue bonds (also known as debt securities) which are fixed‑interest securities with a defined term (often several years) and regular interest payments. Simply put: you lend your money, receive interest and get the capital back at the end of the term.

Bonds are among the more defensive investment types and interest investors who value predictable returns may consider them. You can use the investment to stabilise a portfolio and combine it with other investment types.

Opportunities:

  • Predictable returns: The regular interest payments offer a reliable income source.

  • Repayment at end of term: With reputable issuers repayment is regarded as likely.

  • Wide selection: Depending on risk appetite and investment goal various bonds are available.

Risks:

  • Issuer default: If the debtor becomes insolvent a loss looms.

  • Interest rate risk: If the general interest rate level rises the price of existing bonds falls.

Current accounts

If you want to invest your money with low risk, the current account with variable interest rates may be an option. You deposit money in a current account at your bank, where you regularly receive interest. Unlike fixed‑term deposits, you can access your funds at any time.

Due to its high flexibility, the current account at your bank is suitable as a short‑term parking spot for emergency savings or as a temporary solution before larger investments. Investors often refer to current accounts as the best risk‑free investment, since the capital is protected by statutory deposit insurance.

Opportunities:

  • Flexibility: Your money is always accessible in your current account and you remain liquid.

  • Planning certainty: You receive variable interest on your bank’s current account.

  • Deposit insurance: Balances are protected within the EU up to €100,000 per bank and per person.

Risks:

  • Low interest: Compared to other investments, the interest is usually low.

  • Interest rate fluctuations: The bank can adjust the interest rate at any time.

  • No inflation protection: If interest is lower than the inflation rate, your money loses purchasing power.

Fixed‑term deposits

If you choose fixed‑term deposits as an investment type, you deposit a certain amount with a bank for a fixed term at a fixed interest rate. During this time, however, you can’t access your money. In return, you receive predictable interest over the entire term, regardless of developments in the capital market.

A fixed‑term deposit account is therefore suitable for investors who won’t need their capital in the coming years and want to park it without market fluctuations.

Opportunities:

  • Fixed interest: You know from the beginning how much interest you’ll receive on your deposit.

  • Stability: Your capital is not affected by market fluctuations.

  • Deposit protection: Within the EU, the deposit insurance of €100,000 per person and per bank applies not only to current accounts but also to fixed‑term deposits.

Risks:

  • No flexibility: You cannot access your money during the term.

  • Inflation risk: If inflation rises, the real return on your investment decreases.

  • Limited earning potential: Compared to riskier investments, interest on fixed‑term deposits is often low.

Crypto

Cryptocurrencies are decentralised virtual currencies, including Bitcoin and Ethereum. Coins and tokens are based on a blockchain and use cryptographic methods to secure transactions, generate new units and ensure the integrity of the network. They exist purely digitally and are independent of the banking system and traditional currencies (fiat money). Investors who choose cryptocurrencies are opting for a modern investment form with high growth potential but also greater risk, since coins and tokens are volatile.

Opportunities:

  • High return potential: Early investments in established coins and tokens have delivered remarkable profits in the past (Note: Past performance is not an indicator of future results).

  • Independence: Crypto assets are decentralised and freely tradable.

  • Innovation: New applications are constantly emerging with technologies like smart contracts, DeFi or NFTs.

Risks:

  • Price fluctuations: The market is very volatile, and short‑term crashes are common.

  • Regulatory uncertainty: Legal frameworks can change quickly, affecting trading or custody.

  • Value protection: Unlike traditional currencies, the value is not backed by government institutions.

Did you know? Cryptocurrencies can be an exciting part of an investment strategy and contribute specifically to diversifying your portfolio. For retirement planning or secure wealth building, you should base your strategy on multiple pillars and combine it with other investment forms.

At Bitpanda, you can start investing in Bitcoin, Ethereum and many other digital assets with small amounts. This allows you to smartly integrate crypto into your overall portfolio.

How much money should I invest?

How much money you should invest depends on your income, your life situation, your goals and your risk tolerance. There’s no universal answer – but there are useful guidelines like the 50-30-20 rule.

The 50-30-20 rule states:

  • 50% of your net income goes to fixed costs like rent, insurance and groceries.

  • 30% can be used for personal wants, leisure or hobbies.

  • 20% should be saved and invested, meaning allocated to building your wealth.

How you divide that 20% across different investment forms depends on your investment strategy and whether you want to invest safely or take on a bit more risk. A mix of investment forms can combine advantages and disadvantages.

Example: If your monthly net income is €2,000, you can invest €400 according to the 50-30-20 rule to build wealth. For instance, you could invest €200 in ETFs, place €100 in a current account and invest €100 in cryptocurrencies.

With an income of €3,500, you could invest €700 in financial assets. Spread various amounts across securities, combine investments for retirement planning and reduce the risk of your investments.

What should I consider when investing money?

When it comes to investing money, it’s not just about where and how investors put their money – it’s especially about being well-informed and well-prepared. A sound strategy is important for building wealth – from the initial budget planning to the ongoing optimisation of your portfolio. That’s why there are certain aspects to consider both before and after investing.

Before investing:

  1. Check your financial situation: Work out how much money you can set aside each month or year, and how much of that you genuinely want to invest. It’s worth setting a budget and analysing which expenses are fixed and where you can save. Also, set aside an emergency fund and pay off consumer debt before you start investing.

  2. Define investment goals and strategies: Do your research, familiarise yourself with the various investment types, and define your goals. Consider whether you want to invest mid- or long-term, how many years your money should work for you, and whether security or potentially higher returns with greater risk are more important to you.

  3. Select suitable products: Once your budget is set and your goals are defined, the next step is choosing from the available options. Which securities and investment types are best suited to help you reach your goals? Diversify your portfolio to cushion potential losses, and take advantage of the cost-average effect by, for example, incorporating an ETF savings plan into your strategy.

After investing:

  1. Adjust your portfolio regularly: Monitor how your investment is developing and adjust it if necessary. For instance, reallocate profits from sharply rising securities, or adapt your portfolio to your risk tolerance.

  2. Monitor the market: Political events, technological trends and economic developments all impact your investment. Keep an eye on fluctuations, but don’t act hastily – stay focused on your long-term goals. A market crash can be evened out over several years.

Conclusion: Build capital through investments

Investing money means taking responsibility for your financial independence. Retirement, buying a home, that dream holiday, or the desire for financial freedom? You don’t need a large starting capital or deep financial knowledge to begin. Even small amounts can help you build wealth year after year through various investment types.

What matters is solid preparation, a mix of investments (e.g. fixed-term deposits at your bank, cryptos and shares) that match your investment goals, and regular adjustments to your strategy. You should also understand the risks of investing to avoid unpleasant surprises. As you can see, investing money is easier than most people think.
