Rent versus mortgage payment in Prague: a monthly comparison

Every Prague renter has done the sum on a napkin. The rent for a flat is X. The mortgage on the same flat would be about the same. So why keep paying a landlord? The napkin is right about one thing and wrong about several. The mortgage instalment and the rent are both monthly payments. They do not buy the same thing, and they do not cover the same costs.

This article walks through one hypothetical flat, paid for two ways, and shows how to build your own comparison. The prices, rates and rents below are invented to show the arithmetic. They are not market data, and you should substitute current figures from listings and from a bank.

The setup

Imagine, hypothetically, a flat that costs CZK 6,000,000 to buy. You hold CZK 1,200,000 of own funds, a deposit of 20%, and borrow CZK 4,800,000 over 30 years. Suppose the same flat could be rented for CZK 25,000 a month. Everything else is an assumption you can change.

At a hypothetical annual rate of 5%, the instalment on CZK 4,800,000 over 30 years is about CZK 25,767 a month. The arithmetic is the annuity formula we set out in how the monthly payment is worked out. At 4% it would be about CZK 22,916, and at 6% about CZK 28,778.

On those numbers the instalment is close to the rent, which is the napkin result. Now look inside the instalment.

Interest is the cost, principal is the saving

In the first month at 5%, the interest on CZK 4,800,000 is CZK 20,000. The remaining CZK 5,767 of the instalment repays principal. That portion is not lost. It reduces your debt and builds your share of the flat. So the cost of owning the loan is the interest, not the whole instalment, and the cost of renting is the whole rent, which builds nothing.

By that measure the hypothetical owner pays CZK 20,000 in interest against the renter's CZK 25,000 in rent. But the owner has more costs, and the renter has some the owner does not.

The costs owners carry

On the same hypothetical numbers, the owner's economic cost is higher than the rent. Interest of CZK 20,000, building charges of CZK 4,000, insurance, tax and upkeep of CZK 2,000 and CZK 3,000 of lost earnings on the deposit come to CZK 29,000. Rent is CZK 25,000. Ownership starts out CZK 4,000 a month dearer in this example, even though the cash instalment looks the same as the rent. The owner is paying with a promise of future gains: repaying principal and, if prices rise, a flat that is worth more.

Each of those lines is real. Building charges are paid to the owners' association or cooperative and cover the repair fund, services and insurance of the building; see our guide to service charges and building funds. Property tax is calculated by area and municipality, not by price, as explained in the annual property tax explainer. Repairs are the owner's, and a boiler or a bathroom does not wait for a convenient month. The deposit of CZK 1,200,000 could otherwise sit in a savings account or an investment.

Then there are the one-off costs of buying, which the monthly comparison hides: the cadastre fee, the lawyer, any agent's fee and the costs of moving in. Our breakdown of the real cost of buying a flat lists them. A borrower pays no acquisition tax on a purchase, because Czechia abolished it in 2020.

The costs renters carry

A renter pays a deposit of up to three months' rent, which the landlord must return at the end of the lease, with interest, less justified claims (as of 2026; check the Ministry for Regional Development). A renter pays for energy and any services outside the rent, and takes the risk that the rent rises when the lease is renewed. The statutory route for rent increases has limits, and the lease may set its own mechanism, so check the current rules before you rely on a number (check the Ministry for Regional Development).

A renter also keeps flexibility. A tenant on an open-ended lease can usually end it with three months' notice, and a landlord can end it only on legal grounds. An owner who must leave in two years has to sell, and the costs of buying and selling can outweigh the gains from a short stay. Our explainer on the tenure mix in Czechia puts the choice in a national context.

What changes the answer

Three variables move the result more than any others. The rate: the difference between 4% and 6% on this hypothetical loan is nearly CZK 6,000 a month in the instalment, and the rate applies only for the fixation period; the guide to fixation periods explains what happens at refixation. The holding period: the longer you stay, the more the one-off costs are spread and the more principal you repay. Price movement: if the flat gains in value, the owner profits; if it falls, the owner bears the loss. Nobody can forecast it, and this article does not.

To test combinations of price, deposit and holding period, you can use the buy or rent calculator on Hypoteky.com, which compares the long-run costs of owning and renting under assumptions you set, and the mortgage calculator on Hypoteky.com to model the instalment. Both are tools for orientation. A bank's offer will differ.

Can you get the loan at all? The central bank recommends a maximum loan-to-value of 80%, or 90% for applicants under 36, and the income limits are off (as of 2026; check ČNB). Each bank tests your income. See how much you can borrow.

Frequently asked questions

Frequently asked questions

Is a mortgage cheaper than renting in Prague?

It depends on price, rate, rent, deposit and how long you stay. The instalment can look similar to rent, but the owner also pays charges, upkeep and tax and gives up the earnings on the deposit.

Is the whole mortgage instalment a cost?

No. The interest is the cost. The principal repays the debt and builds your equity.

How much deposit do I need?

The central bank recommends a maximum loan-to-value of 80%, or 90% for applicants under 36, so a deposit of 10% to 20% plus costs is the usual range (as of 2026; check ČNB).

What if I might leave Prague within a few years?

Include the costs of buying and selling in your comparison. A short stay often favours renting.

A practical next step

Fill in the table above with a real flat and your own numbers. If the difference between the two columns is small, decide on risk and flexibility rather than on the monthly figure. If it is large, check your assumptions.
