Give the bank less risk and more business. A lower LTV, your salary and current account at the bank and possibly its insurance all help, but nothing works as well as a competing offer on paper. The price list is where talks start, not where they end.
In October 2026 banks advertise an average of 5.79 % according to Swiss Life Hypoindex (an index of advertised rates), yet the contracts actually signed in August averaged 5.00 % (ČBA Hypomonitor, the Czech Banking Association's mortgage statistics).
Each tenth of a percentage point has a price. On a CZK 4,000,000 mortgage over 25 years it is worth CZK 232 a month and roughly CZK 19,600 in interest over a five-year fixed-rate period (fixace). Half a point, which well-prepared negotiation can win, comes to around CZK 100,000 per fixed period.
Seven levers that really move the rate
| Lever | Why the bank listens | What it does to the rate |
|---|---|---|
| LTV below 80 %, ideally below 70 % | less risk and lower capital requirements for the loan | bank price lists have LTV bands; moving to a lower band is often one of the biggest discounts |
| A competing offer | the bank does not want to lose a client it could sell other products to | most often matching it or undercutting by tenths of a pp |
| An active account and income with the bank | it sees your cash flow, earns fees and deposits | a rate discount (bonifikace) conditional on account turnover; the rate rises if you do not meet it |
| Insurance with the bank | commission from the insurance and lower risk of default | a discount for life insurance or payment protection insurance |
| Length of the fixed period | the market price of money differs by term | in October 2026 a one-year fixation is the cheapest; banks have raised long fixations the most |
| Energy class A/B | the bank's green funding | usually 0.1–0.3 pp (green mortgage) |
| Timing | price lists change even within a month | in September 2026 Moneta cut rates on 10 Sept, while Česká spořitelna raised most fixations by 0.3 pp on 11 Sept |
How big each discount is varies from bank to bank and changes with the price list. So always ask for the final rate and the conditions attached to it, not for a list of individual discounts.
Does the insurance discount pay?
The most common “discount” that saves you nothing is a rate cut for insurance you would not otherwise buy. The test is simple: the discount in CZK a month has to be bigger than the extra premium.
- A 0.2 pp discount on CZK 4,000,000 over 25 years is worth CZK 464 a month.
- With a premium of, say, CZK 350 a month you are CZK 114 better off and insured as well. That is a good deal if you wanted the cover anyway.
- With a premium of CZK 600 a month you lose CZK 136 a month. Take the rate without the discount and buy your own insurance elsewhere, or none.
Ask too whether you can cancel the policy later and what happens to the rate if you do. The terms of mortgage-linked insurance are covered in Life insurance for a mortgage.
How do you get from a 5.39 % price list to 4.90 %?
Petr and Jana at the negotiating table
They are buying a flat for CZK 5,000,000 and need CZK 4,000,000 over 25 years with a five-year fixed period. Their bank's first offer is the price-list rate of 5.39 %, a payment of CZK 24,301.
- They show own funds of CZK 1,000,000 in their account, so the loan stays within LTV 80 % and drops into the cheaper band.
- Both salaries move to the bank, and they accept the active-account condition.
- They bring a written offer from another bank at 5.00 %.
- Their bank undercuts it and approves an individual rate of 4.90 %, a payment of CZK 23,151.
That is CZK 1,150 a month less, and ≈ CZK 96,000 less interest over the five-year fixed period (CZK 1,022,969 against CZK 926,597), for a few hours' work. The rates are illustrative; individual offers in October 2026 range between 4.7 and 5.8 %.
How the conversation goes
- Know your numbers: the price, the amount you need, the LTV, your net income and other repayments. You are treated differently when you know that 80 % LTV puts you in a cheaper band.
- Get 2–3 written offers that show the APRC (RPSN) and the conditions for each discount. A spoken “we can do that for you” carries no weight.
- At the bank you prefer, open with a question: “What is your best individual rate for 80 % LTV and a five-year fixation if I move my income to you?”
- Then put the competing offer on the table: “Bank X is offering me 5.00 % on the same terms, with an APRC of Y. Can you match it or beat it?”
- Give the bank time. Individual rates are often approved at head office, and that takes days.
- Ask for the offer in writing with a validity date. Price lists change, and the approved rate should hold until you sign.
The same approach works at the end of a fixed period, where a refinancing offer ready to go is the stronger card. See Refixing vs. refinancing.
When the bank will not budge
Your position weakens wherever the bank carries more risk or runs into regulation. Before you push on the rate, try to fix these weak spots.
An LTV above 80 % (for applicants over 36) is the biggest. Banks may grant such loans only within the exception of up to 5 % of volume per quarter, so they ration them and charge more. Adding even a few hundred thousand to your own funds often does more than any amount of negotiating.
Repayments close to the bank's internal threshold (usually 45 % of net income, 50 % under 36) leave you nothing to bargain with, because you are on the edge of approval. A longer term, a co-applicant or paying off a consumer loan will help.
A short employment history or a newly started business gets you a loan, but at the price-list rate. If you can, wait until the probation period ends or your next tax return is filed.
Adviser or branch?
A mortgage adviser (hypoteční poradce) compares several banks at once, knows which campaigns are running and which banks will accept your situation. Some banks also have offers just for the intermediary channel. At a branch, a long-standing client with income and savings at the bank can make the most of that relationship. The best results often come from using both: an adviser's offer as leverage at your own bank, or the other way round. For the pros and cons, see Mortgage adviser or bank.
What not to accept, even if the rate looks good
- A discount tied to products you do not need, such as an investment plan, a credit card with a fee or expensive insurance. Convert them to CZK a month.
- A penalty surcharge for missing conditions, with no clear mechanism. Find out by how much and from when the rate rises if, say, your account turnover dips for a month.
- A low rate with high fees for arranging or administering the loan. The APRC decides, not the rate.
- A short fixed period chosen only for the lowest rate, if your budget could not cope with a higher payment at refixing.
- A longer term sold as a “discount”. A lower payment from a longer term is not a lower rate, and you will pay more interest overall.
