TAN
Published 8 November 2026, 22:51
TAN — taxa anual nominal (annual nominal rate)
The bare interest rate on a loan, excluding fees, insurance and taxes: for a variable-rate mortgage it is Euribor plus the spread as of today. It is the figure printed in adverts and quoted over the phone, but it doesn't show the full cost of the loan — that is what TAEG is for.
Where you come across it. A bank advert, a loan offer, the FINE sheet, a mortgage statement.
Two banks with the same TAN can easily differ by half a percentage point in TAEG: the difference lies in fees and insurance.
