With 16,000 km a year, always charging at home costs about €1,092 on a 24-hour tariff and €612 at the night rate: you save 480 € a year. Note: on a night rate the day rate is usually a little higher than the 24-hour rate, so it pays off most if you can also move other usage to the night. An EV tariff (such as Night Boost) is cheaper still in its short window.
