Key Data and Facts
The savings plan formula accounts for contributions made at the beginning or end of each period. Flat-rate tax: 26.375%. Saver lump sum: 1,000 euros/person.
Step-by-Step Guide
How to calculate your savings goal step by step: 1. Set the savings rate: determine the monthly amount you can save regularly. Rule of thumb: 10-20 % of net income. 2. Enter the interest rate or return: overnight money (Tagesgeld): about 2.5-3.5 % (2026). Fixed-term deposit (Festgeld): about 3.0-4.0 %. Mixed portfolio: about 4-6 %. 3. Choose the savings period: how many years do you want to save? 4. Calculate the final capital: savings plan formula (in arrears): final capital = savings rate x ((1 + monthly interest)^months - 1) / monthly interest. With payment in advance, an additional month of interest is calculated. 5. Alternatively: specify a target capital and calculate the required savings rate. 6. Account for taxes: interest income is subject to the flat-rate withholding tax (26.375 %). The saver's lump-sum allowance (1,000 EUR) reduces the tax burden. Example: 300 EUR monthly savings rate, 3 % interest, 10-year savings period. Paid in: 300 x 120 = 36,000 EUR. Final capital: 300 x ((1.0025)^120 - 1) / 0.0025 = 41,927 EUR. Gross interest income: 5,927 EUR. After deducting the saver's lump-sum allowance (1,000 EUR) and the flat-rate withholding tax: about 4,629 EUR net return. Net final capital: about 40,629 EUR. If you invested the same sum all at once: 36,000 x 1.03^10 = 48,382 EUR (since compound interest acts on the full amount from day 1).
Calculation Example
300 EUR/month, 3% interest, 10 years. Paid in: 36,000 EUR. Gross final capital: 41,927 EUR. Interest yield: 5,927 EUR. After tax (less the allowance): approx. 40,629 EUR net.
