Step-by-Step Guide
How to calculate the interest on your overnight money (Tagesgeld) step by step: 1. Enter the investment amount: the amount in your overnight money account. 2. Specify the interest rate: the current overnight rate (2026: about 2.5-3.5%). New-customer offers often provide higher rates for a limited time. 3. Set the investment period: since the interest rate is variable, you can simulate different periods. 4. Interest calculation: interest = investment amount x interest rate x days / 365. With monthly or quarterly crediting, a slight compound interest effect arises. 5. Deduct taxes: earnings above the saver's lump-sum allowance (1,000 EUR) are subject to 26.375% withholding tax. Set up an exemption order with the bank. Example: 25,000 EUR overnight money, 3.0% interest rate, 1 year. Gross annual interest: 25,000 x 0.03 = 750 EUR. As this is below the saver's lump-sum allowance (1,000 EUR): no tax with an exemption order. Net return: 750 EUR. At 50,000 EUR: interest 1,500 EUR, taxable 500 EUR, tax about 132 EUR, net: 1,368 EUR.
Calculation Example
