Most variable mortgages in the euro area are revised on the monthly average, not the daily value. A loan that resets in August on the 6-month Euribor plus 1 pp would pay 0.47 % for the coming period.
Every number on this page is a published fixing, not an estimate: daily values come from the Bank of Finland's copy of the Euribor series, monthly averages are the arithmetic mean of those fixings and are cross-checked against the ECB Data Portal, and the tables are rebuilt each 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.
