The bank sends a letter saying your interest rate has changed, and the monthly payment jumps. Here is where that number comes from, when it actually reaches you, and what one percentage point costs in euros.
Euribor is the rate at which euro area banks lend to each other short term. It is calculated and published by EMMI every business day for separate tenors: one week, one, three, six and twelve months. Estonian home loans are overwhelmingly tied to the six-month Euribor, so that is the one this article follows.
Six-month Euribor stands at 2.80% today (quote of 9 September 2026). In historical terms that is a middling level: the highest reading on record is 5.41% (October 2008), the lowest −0.54% (December 2021).
Figures come from the Bank of Finland, which publishes the rates calculated by EMMI — suomenpankki.fi. Quotes appear with a one-day lag, so today's figure is the previous banking day's.
A loan contract has two parts, and it pays to keep them apart:
Together that makes 4.80% today. The margin is negotiable only by amending the contract; Euribor is not negotiable at all. That is exactly why it is worth knowing what a move in Euribor does to your budget.
Take a typical home loan: €150,000 over 30 years, annuity schedule, margin 2.00%. At today's Euribor the rate is 4.80% and the monthly payment €787.
If Euribor rises by one percentage point, the payment goes to €880.13. That is €93.13 a month, or €1,117.58 a year. A two-point rise takes the payment to €977.89 — €190.89 a month more than today.
The effect scales with the outstanding balance: twice the loan, twice the impact. A shorter term softens the blow, because interest makes up a smaller share of each payment.

Euribor moves every day; your payment does not. The contract names a reset date, and the value fixed then applies until the next reset — half a year with six-month Euribor. So today's market move can take up to six months to reach your payment, and the reverse also happens: your payment can rise in a month when the news is all about rates falling.
On an annuity schedule the payment stays flat until the next reset, but its composition shifts month by month: the interest part shrinks and the principal part grows. When the rate rises, interest takes a bigger bite and the balance comes down more slowly.
Between 2015 and 2022 Euribor was negative, bottoming at −0.54% (December 2021). Many Estonian loan contracts state that a negative Euribor is treated as zero, meaning the rate never falls below the margin. Whether your contract has that clause is worth checking: it decides how much of any decline actually reaches you.
In our example a Euribor of zero would mean a payment of €554.43, with the margin 2.00% as the entire interest rate.
This is a general explanation, not financial advice. The terms that matter — reset date, floor, margin — are in your own loan contract.
On a loan of €150,000 over 30 years the monthly payment goes from €787 to €880.13 — €93.13 a month, €1,117.58 a year. The effect is proportional to the balance: twice the loan, twice the increase.
2.80%, quote of 9 September 2026. The rate is calculated by EMMI and published by the Bank of Finland with a one-day lag. The historical high is 5.41% (October 2008).
On the reset date written into your contract. With six-month Euribor the rate is re-read twice a year, so today's market move may take up to six months to show up.
It depends on the contract. Many include a zero floor, meaning the rate never drops below the margin of 2.00%. The lowest reading on record was −0.54% (December 2021).
The margin is a contractual term and can only be changed by amending the contract, usually for a bank fee. The Euribor part is not negotiable — it comes from the market.
