What is the Overnight Deposit Calculator?
The overnight deposit calculator computes interest income on call money accounts. Funds remain available daily and interest is typically credited monthly or quarterly.
How does the Overnight Deposit Calculator work?
Enter the deposit amount, interest rate, term in days and how often interest is credited (monthly, quarterly or annually). The calculator accrues interest daily and compounds credited interest. Flat-rate tax and solidarity surcharge are calculated per investment year after the saver's allowance (1,000 EUR, 2,000 EUR for joint assessment).
Key Data and Facts
Deposit guarantee: 100,000 euros per customer and bank (EU-wide). Variable rates, no notice period. Flat-rate tax applies to income above the saver lump sum.
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: your bank's current overnight rate (ECB average for overnight deposits 08/2026: 0.5 % including current accounts; good overnight-money offers are clearly higher). 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 per year, 2,000 EUR for joint assessment) 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 with annual crediting: 25,000 x 0.03 = 750 EUR (with monthly crediting 760.40 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
25,000 EUR call money, 3.0% interest, 1 year. Gross interest: 750 EUR. With an exemption order (under the 1,000 EUR allowance): no tax. Net yield: 750 EUR.
