The interest professionals explain this using an example calculation: Anyone who took out construction financing of 400,000 euros at a debit interest rate of 0.89 percent and a 10-year debit interest rate in December 2020 could now make a special repayment of 50,000 euros two years later . The savings at the end of the fixed interest rate are around 3688 euros.
If consumers instead invest 50,000 euros in a fixed-term deposit account with the current effective interest rate of 2.70 percent per year for the five following years, there is a return of 7124 euros. If the customer uses the annual savings allowance of 801 euros, 4005 euros are tax-free – the remaining 3119 euros are subject to 25 percent capital gains tax. This results in a total return after taxes of 6344 euros and thus 2665 euros more than through the special repayment for construction financing. This simplified calculation leaves out solos and church taxes.
