The TAN is your loan's rate (Euribor + spread). By law the early-repayment fee is capped at 0.5% of the capital repaid on variable-rate loans and 2% on fixed-rate ones, and it may be temporarily waived. Check the current figure on your loan's information sheet.

Educational estimate, not financial advice. It assumes the TAN stays constant to the end of the term (on a variable rate the payment moves with Euribor) and a single early repayment. Confirm the fee and the figures on your loan's information sheet.
