01Costs

What is TER?

TER (Total Expense Ratio) is the yearly fee for managing an ETF. It is shown as a percentage and is taken from the fund's value automatically. You don't see it on your statement directly – it just reduces the daily price of the ETF unit.

Example: an S&P 500 ETF with a TER of 0.07%. If the index rises 10% in a year, the ETF will rise about 9.93% – the difference is the fee. TER applies to all ETFs, whether accumulating or distributing.

0,07%

Vanguard FTSE All-World (VWCE) – very low TER

0,20%

Typical sector ETF

0,50%+

Expensive ETFs or active funds

Even a small difference in TER makes a huge difference over the long term. With an investment of $100,000 over 30 years and an average annual return of 7%, the difference between a TER of 0.07% and 0.5% is about $30,000 less in the final amount.

Always check the TER before buying an ETF. For global indexes, a good TER is below 0.2%. The lower it is, the more stays in your pocket.

02Inflation

How inflation lowers the real value of money

Inflation is the increase in prices of goods and services over time. It means that the same amount of money buys you less in the future. If inflation is 3% per year, in 10 years $100,000 will have the buying power of about $74,000 (if you just keep it as cash).

For an investor, what matters is the real rate of return – that is, the nominal gain minus inflation. If your savings account pays 4% and inflation is 5%, you are actually losing 1% of purchasing power. Investing in stocks or ETFs makes sense because over long periods their nominal returns have been higher than inflation.

2–3%

Typical yearly inflation (central bank targets)

7–10%

Long‑term average stock market return

~5%

Real return from stocks (after inflation)

Keeping cash under the mattress guarantees a loss of value. Inflation is a silent killer of savings – to fight it, you must invest.

03Bonds

Inflation and bond yields

Bonds are debt instruments – you lend money to an issuer (government or company) in exchange for interest. The level of interest (the coupon) is closely tied to expected inflation. When inflation rises, newly issued bonds must offer higher yields to be attractive to investors.

That is why when inflation is high, the prices of existing fixed‑rate bonds fall – nobody wants to pay full price for a bond that pays lower interest than new issues. This is the basic interest rate risk of investing in fixed‑rate bonds.

There are also inflation‑linked bonds (e.g., TIPS in the US, or similar products in other countries). Their interest rate is made up of a fixed margin plus the inflation rate. That way, the real value of the capital is protected – if inflation rises, the interest rises too.

Inflation‑linked government bonds

Interest rate = inflation + fixed margin (e.g. 1%)

Protect the real value of capital

Good for periods of high inflation

Fixed‑rate bonds

Fixed coupon for the whole term

Lose value when inflation rises

Price falls before maturity

04Protection

How to protect against inflation

📈

Invest in stocks / ETFs

Companies can raise prices, so over the long term stock returns exceed inflation.

🏦

Choose inflation‑linked bonds

In many countries there are government bonds whose interest is tied to the inflation rate. They protect your capital from losing purchasing power.

🥇

Commodities and gold

In times of high inflation, gold and commodities often hold their value or increase in price.

🏠

Real estate

Rental prices and property values tend to rise with inflation.

The simplest strategy: a global stock ETF (e.g. MSCI World) plus a portion in inflation‑linked bonds. In the calculator you can add both components and see how they perform under different inflation scenarios.

05Together

TER + inflation – the double enemy of investors

Inflation reduces the real value of your money, and TER eats into your nominal returns. Together they can significantly reduce the power of compounding.

-2,5%

Inflation

~4,3%

Real net return

To achieve a real profit, the nominal return must exceed the sum of inflation and costs. By choosing ETFs with low TER and investing in assets that have historically handled inflation well (stocks, inflation‑linked bonds), you increase your chances of preserving your purchasing power.

Summary: control your costs (choose low TER) and don't leave cash idle – invest in assets that beat inflation over the long term. This is the foundation of effective wealth building.
