Euribor mortgage calculator: your payment at the next reset
12-month Euribor: 3.262 % (22 October 2026)
Your payment at the next Euribor reset
The forecast covers resets up to 12 months ahead.
Forecast: the rate today's Euribor curve implies for your tenor on the reset date. Both payments use the same balance and term, so the difference is the rate alone. An illustration, not an offer: your lender applies the fixing or average your contract names.

Forward rates implied by the Euribor curve of 22 October 2026. Payment: €150,000 over 20 years with a margin of 1.00 pp on the 12-month Euribor.
A variable-rate loan is repriced on its reset date: the lender takes the Euribor tenor named in the contract, adds your fixed margin and recalculates the payment for the balance and term left. Until then the payment does not move, whatever Euribor does. Enter what is left on your loan, your margin, the tenor and the date of your next reset to see both numbers side by side.
The forecast is the forward rate implied by the curve of 22 October 2026, so it already contains what money markets expect from the ECB's next decisions. It is not a prediction: forward rates have missed in both directions, and the curve moves every business day. Past 12 months the curve is extended at its 6-to-12-month forward rate.

Euribor is the rate at which euro-area banks lend to each other for a fixed term, published every business day by the European Money Markets Institute. This site republishes the official fixings with a 24-hour delay, which is why the newest date is usually yesterday's.
Variable-rate mortgages across Europe are priced as this fixing plus a fixed spread. When the fixing moves, the payment moves at the next revision date written in the loan contract, and the direction that matters to a borrower is simple: up.
Every number on this page is an official published fixing, not an estimate: daily values are the Euribor fixings as published in the ECB / Eurosystem's official statistics, monthly averages are the arithmetic mean of those fixings and are cross-checked against the ECB Data Portal, and the tables are refreshed every business day after the previous day's fixing appears. Tenors use the ACT/360 convention. Where a monthly average differs from the ECB figure by more than a hundredth of a point the methodology page lists the case.
Most variable mortgages in the euro area are revised on the monthly average, not the daily value. A loan that resets in October on the 12-month Euribor plus 1 pp would pay 4.25 % for the coming period.
What the calculator does
The calculator answers one question: given the outstanding balance, the remaining term, the Euribor reference and the spread, what is the monthly instalment? It performs the same three steps a bank performs at a revision. It adds the spread to the reference to get the annual rate. It divides that rate by twelve to get a monthly rate. It then applies the annuity formula, which finds the constant monthly payment that repays the balance exactly over the remaining number of months at that monthly rate.
The reference is the newest fixing in the database, from 22 October 2026, for the maturity of the page: the 12-month rate on the main calculator page, and each of the five maturities on its own maturity page, which the links below the calculator lead to. The reference itself is not an input; the three fields you can change are the outstanding balance, the spread and the remaining term. If your contract uses a monthly average rather than a daily fixing, the month pages on this site give that figure; in ordinary months it lies close to the fixing. A table on the page also shows the instalment for a standard loan at several spreads across all five maturities. Everything runs in your browser; nothing you enter is sent anywhere.
Index plus spread
The rate the calculator applies is the reference plus the spread, nothing more. On the main calculator page, with the 12-month fixing of 22 October 2026 and a spread of one percentage point, the rate used is 3.262 % plus 1.00 point. The spread is the fixed part of your rate and is written in your contract; the reference is the variable part. Entering a spread of zero shows the effect of the reference alone.
Remaining term
The term to enter is the number of years still to run on the loan, not the original term. A shorter remaining term makes the instalment less sensitive to the rate, because a larger share of each payment is capital repayment; a longer remaining term makes it more sensitive. This is why the same change in Euribor costs a borrower in the first years of a thirty-year loan considerably more per month than a borrower with five years left.
What it does not model
The calculator is deliberately simple, and the simplifications matter:
- Rounding. Banks may round the reference, the total rate or the instalment to a set number of decimals, sometimes upwards. The calculator rounds only the displayed result.
- Floors and caps. A contract may treat a negative reference as zero, or limit how far the rate can rise. The calculator applies neither; enter the floored or capped rate yourself if one applies.
- Fees and insurance. Account fees, compulsory insurance and other charges added to the monthly debit are not included. The figure shown is principal and interest only.
- Partial repayments. If you have made or intend to make extra repayments, the balance and possibly the term change; enter the balance after the repayment.
- Conventions. Banks may compute interest on an ACT/360 or other day-count basis, or with a different compounding rule. The calculator uses a plain monthly rate of one twelfth of the annual rate.
The result is therefore an estimate of the interest effect, accurate to within a few euros of a bank's figure in ordinary cases, not a reproduction of your statement.
Reading the previous revision comparison
Beside the main result the calculator shows what the same loan would pay with the previous month's monthly average of the same maturity in place of the newest fixing, with that average shown in the label, and the difference between the two instalments per month. This isolates the effect of the change in Euribor from everything else: the balance, the term and the spread are held equal in both calculations. A positive difference means the reference has risen since the previous month's average and the instalment at the current fixing is higher; a negative difference means it has fallen. The monthly average is used for the comparison because it is the figure most revisions are based on, so the previous-month instalment is close to what a loan revised on that average would have paid, while the current instalment shows where the daily fixing has moved since.
Frequently asked questions
How does the Euribor mortgage calculator work?
It adds your spread to the Euribor reference shown, which is the newest fixing of 22 October 2026 for the maturity of the page, and applies the resulting annual rate to the outstanding balance over the remaining term with the standard annuity formula. The result is the constant monthly instalment that repays the loan in full over that term at that rate.
Why does the calculator's figure differ from my bank's?
The calculator uses a simplified model. Banks may round the reference or the rate, apply a floor or a cap, use a different day-count or compounding convention, and add fees or insurance to the instalment. Small differences of a few euros are normal; a large difference usually means a different reference, spread or term was used.
What does the previous revision comparison show?
It recalculates the same loan with the previous month's monthly average of the same maturity in place of the current fixing, and shows the difference between the two instalments. Balance, spread and term are identical in both, so the difference isolates the effect of the change in the reference between the previous month's average and the newest fixing.
