EuriborHow 12-month Euribor affects a loan
Guide · 12-month Euribor · Euribor.site
A floating euro loan does not copy this morning’s headline into the standing order. It waits for a review date, reads the 12-month average named in the deed, adds a contractual spread, and only then rebuilds the payment.
All-in coupon ≈ monthly 12-month Euribor of the reference month + spread (± floor or rounding). That coupon feeds a French amortization formula for the remaining term.
Annual review: you live with last year’s coupon until the anniversary. Semiannual review: two windows a year. A 0.40-point drop in March does nothing in April if the next review is November.
Work the euros, not the adjectives. Open payment delta for +0.25 and +0.50 points, or loan impact for a custom rate. Max loan turns a monthly budget into a principal at the current fixing plus spread.
Two loans with the same Euribor print can pay different amounts: different spreads, remaining years, floors, or insurance packed into the installment. Compare letters, not only indexes.
Dollar mortgages do not reprice off this table. If the search came from a U.S. box, read Euribor vs SOFR first so the wrong index does not enter the cell.
When a letter arrives: copy tenor, month and spread from the clause; take the closed average from history or the home cards; add the spread; run the tool; then argue if a real gap remains.
Also: which number is “current”, how the average is built, +1% / +2% stress.
