Mortgage fixation in Czechia: choosing between 1, 3, 5 and 10 years

A Czech mortgage of 25 or 30 years is not one contract at one rate. It is a long loan cut into periods, each with a rate agreed in advance. The choice of period is the one place where the borrower can decide how much of the interest-rate risk to carry, and how much to hand to the bank. It is also the choice that produces the loudest regrets, in both directions.

This explainer sets out how fixations work, the questions that separate them and what happens when each ends. It does not recommend a period. The right one depends on your income, plans and tolerance for uncertainty, and a regulated adviser can talk through it with you.

What a fixation is

During a fixation (fixace), the interest rate in your contract does not change. The monthly payment is stable, and the split between interest and principal follows the schedule. At the end, the bank sends a proposal for the next period. If you do nothing, many contracts roll the loan into a new fixation at the rate proposed. Our explainer on Czech mortgage rates describes what feeds into the rate.

Banks usually offer a menu of periods, commonly one, three, five and ten years, and sometimes others. Each is priced separately. The prices on offer on a given day reflect the market for that horizon plus the bank's margin.

The trade-off

The choice is a trade between certainty and flexibility.

There is no permanent ranking of which is cheaper. Sometimes the market charges more for a long fixation than a short one, and sometimes less. A borrower choosing a period is therefore betting on two things at once: where rates will be, and where their own life will be.

Questions to ask about your own situation

These are prompts for thinking, not advice.

1. How stable is my income? Variable or uncertain earnings make a stable payment more valuable.
2. How much room is in the budget? A household with little slack is more exposed to a rate rise at the reset.
3. Do I expect to sell or move within the period? If so, what are the charges for repaying early?
4. How much do I pay in interest in a year, and how much would a change of a given size cost? Use a calculator to see the effect. The mortgage calculator on Hypoteky.com lets you vary the rate and the term yourself.
5. Can I make extra repayments? The law already allows one free partial repayment a year (see below), and some contracts are more generous. Check the terms.

What happens at the end

About six months before the end of the fixation, banks usually begin to contact borrowers. You then have four options.

• Accept the bank's offer. The loan continues at the new rate for a new period.
• Negotiate. Banks often improve an offer when a borrower shows a competing quote. Your bargaining position depends on your record, your LTV and the lender's appetite.
• Refinance. Move the loan to another bank, which repays the old one. Our explainer on refinancing covers the break-even logic, and the Hypoteky.com refinancing guide gives an overview.
• Repay. Part or all of the loan, from savings or a sale.

Under the consumer credit act (zákon č. 257/2016 Sb.) the bank may not charge anything for repayment at the end of a fixation (as of 2026; check ČNB). Put the date in your calendar now.

Changing during the fixation

Life does not always follow the fixation. The consumer credit act sets the frame for repaying mid-period (as of 2026; check ČNB and your contract):

• once a year, in the month before the anniversary of the contract, you may repay up to 25 per cent of the loan without charge;
• repayment is also free after the death, or a long illness or disability, of a borrower or co-borrower, where it cuts the ability to repay;
• for loans agreed or refixed from 1 September 2024, selling the flat at least two years after buying it, and settling joint property after a divorce, were added to the free cases;
• otherwise the bank may claim only its reasonably incurred costs, which for a housing loan cannot exceed 1 per cent of the amount repaid early.

One trap: some banks ask borrowers who book a new rate in advance to give up part of these rights in return. Read any such addendum before you sign. Our article on selling a flat with a mortgage describes the most common reason for early repayment.

Mixed strategies

Some borrowers split a loan into parts with different fixations, so that only a portion resets at any one time. The idea is to spread the reset risk. Whether a bank offers this, and on what terms, varies. It adds complexity and administration, so ask about the fees and the paperwork for each part.

Others choose a short fixation initially, planning to fix for longer when conditions suit them. That is a bet on timing, and the market does not announce when conditions have arrived.

Reading the news without being steered by it

Headlines about interest rates tend to pull borrowers towards the period that feels safest in the news cycle: long when rates are rising, short when they are falling. Fixation choices made on the headline of the week are often regretted at the next reset. A better test is to set the question against your own budget: if the rate at the next reset were different by a given amount, could you still pay comfortably? If yes, you can tolerate more flexibility. If no, certainty has value.

Frequently asked questions

Frequently asked questions

Can I change the fixation period during the term?

Sometimes, but it may count as an early change with charges, depending on the contract and the law. Ask the bank, and check the clause before you sign.

Is a ten-year fixation always the safest?

It gives the longest period of a fixed rate, but it also commits you for longer, and the rate on offer reflects the market on the day. Whether it suits you depends on your plans and budget.

What if I miss the end of my fixation?

Many contracts roll over to a new fixation at the rate the bank proposes. Read your contract and note the date, so that you can compare offers before it passes.

Do I pay a fee if I repay at the end of a fixation?

No. Repayment at the end of a fixation is free under zákon č. 257/2016 Sb. (as of 2026; check ČNB).

Two households, in words

Take two hypothetical households with no numbers attached. The first has a stable public-sector salary, a small child and a tight budget, so a rise in repayments at the reset would hurt. A longer fixation gives it a payment it can plan around for years. The second has a variable income from freelance work and expects to move abroad within a few years. If it sells the flat after two years of ownership, a newer loan can be repaid free, but if it wants to keep the flat and move the loan, a long fixation could carry a charge, and a shorter one may fit better. The two reach opposite answers from the same market, because the question is about their lives, not about the market.

Extra repayments

If you plan to make extra repayments from bonuses or savings, time them for the month before the contract's anniversary, when up to 25 per cent can go in free, and ask how the bank applies them: lower payments or a shorter term. Some contracts allow more, and that clause is worth comparing alongside the rate.

The date to diarise

Open your contract, find the end date of the current fixation and set two reminders: one six months before, to ask for offers, and one three months before, to decide. A decision made with time to spare is usually a better one.
