Looking for best savings option to invest 15,750 euros for 3 years. I have 15,000 euros invested in a Savings Certificate since 2018 which is due to mature shortly with 750 euros interest I need the money in 3 years. Looked at the option of 3 year savings bond for 3 years with total interest at 4 percent after 3 years assuming DIRT free. Looked at prize bonds also. What rate of interest would I need to get from banks that would be better than 4 percent allowing for DIRT deduction. Many thanks
