taxa variável

A rate that moves with the market. It is made up of the indexante — usually 3-, 6- or 12-month Euribor — and the spread, the bank's fixed margin. There is also the taxa fixa, where the interest stays the same for the whole term, and the taxa mista, which starts with a fixed period followed by a variable one. In Portugal most mortgages are on a variable rate: according to Banco de Portugal data for July 2026, 39.87% of these loans are linked to six-month Euribor, 31.26% to twelve-month and 24.40% to three-month.
