There are benefits of interest rate variable and fixed. Currently variable interest rates indexed to Euribor are more advantageous taking into account the actual low interest of Euribor and little historical temporal variation of recent years and a certain precision on the  stability variation.

The Euribor (Euro Interbank Offered Rate) is variable. It is the interbank loan rate of the major banks operating in the euro zone. Euribor exists since 1999, the year when the euro was introduced.
