Return on investment (návratnost investice, ROI)

In Czech: Návratnost investice (ROI)

Return on investment (ROI, návratnost investice) shows the percentage profit made on the money put into a property. In Czech, návratnost can also mean the number of years it takes rent to pay back the investment.

Also called: ROI, return on investment, payback period, návratnost investice, doba návratnosti

What it means

Return on investment (ROI), in Czech návratnost investice, compares the total profit from an investment with the money the investor put in: ROI = (all income - all costs) / money invested × 100. For a property, income means net rent over the whole period plus any gain on sale, and costs include purchase costs, repairs, interest and taxes.

Czech uses the word návratnost in two ways. Sometimes it means ROI as a percentage, sometimes the payback period (doba návratnosti): the number of years it takes net annual rent to cover the price of the property. The payback period is roughly the inverse of net yield; at a net yield of 4 % it is about 25 years.

How it works in the Czech Republic

Unlike rental yield, ROI takes financing into account. If a mortgage covers part of the price, you invest less of your own money and ROI on your equity may come out higher, but interest adds to costs and a fall in rent or price turns into a loss more easily. From 1 April 2026 the Czech National Bank recommends a maximum LTV of 70 % for investment mortgages, which is worth factoring in when you plan your own deposit.

Purchase costs include the price, agent's commission, legal services and escrow (úschova), the CZK 2,000 administrative fee for filing the application for entry into the land register (návrh na vklad do katastru nemovitostí) and any furnishing. The real estate acquisition tax (daň z nabytí nemovitých věcí) was abolished as of 26 September 2020, so it is not paid on purchases today.

Always state ROI together with the period it covers: a 30 % profit over ten years is very different from 30 % over three. How any gain on sale is taxed depends among other things on how long you have owned the property; check the current rules with the Finanční správa or a tax adviser.

Practical example

For example, an investor buys a flat for CZK 4,000,000 and pays CZK 4,150,000 in total with costs, all from own funds. Over five years net rent after costs and taxes brings in, say, CZK 550,000, and the flat is then sold for an assumed CZK 4,400,000 after selling costs. Total profit is 4,400,000 + 550,000 - 4,150,000 = CZK 800,000, and ROI over five years is 800,000 / 4,150,000 × 100 ≈ 19 %.

The payback period from rent alone, at CZK 110,000 net a year, would be 4,150,000 / 110,000 ≈ 38 years. The sale price in this example is an assumption, not a forecast; all figures are illustrative.

What to watch out for

  • Clarify whether návratnost means a profit percentage or a number of years.
  • Do not count on price growth; also calculate a scenario where the price stays flat or falls.
  • With a mortgage, include interest and the risk of a rate change when the fixed period (fixace) ends.

Frequently asked questions

What is the difference between ROI and rental yield?

Rental yield looks only at annual rental income against the price. ROI covers the whole result of the investment over a period, including any gain or loss on sale and the effect of financing.

Is there a property transfer tax when buying in Czechia?

No, the real estate acquisition tax was abolished as of 26 September 2020. The administrative fee for filing the land register application is CZK 2,000.

  • Rental yield (výnos z pronájmu)Rental yield (výnos z pronájmu) shows what percentage of a property's price the rent returns each year. Gross yield uses the rent only; net yield first subtracts the owner's costs.
  • Net rental yield (čistý výnos)Net rental yield (čistý výnos) is the annual rent minus the owner's costs, divided by the total purchase cost including transaction costs. It shows a more realistic return than gross yield.
  • Buy-to-let flat (investiční byt)A buy-to-let flat (investiční byt) is a flat bought mainly to rent out or to preserve the value of money, not to live in. Its return depends on the price, rent, running costs, taxes and financing.
  • Mortgage (hypotéka)A mortgage (hypotéka) is a long-term housing loan secured by a lien on a property. The borrower repays it in regular monthly instalments, usually over many years.
  • Interest rate (úroková sazba)The interest rate (úroková sazba) is the price of borrowed money, stated as a yearly percentage. On a mortgage it sets how much of each payment goes to interest and is either fixed for a period or variable.
