What is the Savings Calculator?
The savings calculator shows how regular contributions grow into wealth over time. It is suitable for savings goals and financial planning.
How does the Savings Calculator work?
Enter the monthly contribution, interest rate and savings period. The calculator determines the final capital including compound interest with monthly compounding, with contributions at the end or at the start of each month. The contribution or saving period needed for a given target is calculated by the target savings calculator.
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's allowance: 1,000 euros per person and calendar year (2,000 euros for joint assessment).
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): ECB average 08/2026 0.5 % (including current accounts; good offers are clearly higher). Fixed-term deposit (Festgeld): new business about 2.3 % (up to 1 year) to 2.7 % (over 2 years). 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. For a fixed target capital: determine the required contribution or saving period with the target savings calculator. 6. Account for taxes: interest income is subject to the flat-rate withholding tax incl. solidarity surcharge (26.375 %). The saver's lump-sum allowance (1,000 EUR, 2,000 EUR for joint assessment) applies per calendar year. 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 = 41,922 EUR. Gross interest income: 5,922 EUR. Annual interest only exceeds the allowance in year 9 (1,039 EUR) and year 10 (1,180 EUR); without other investment income only about 58 EUR of tax is due (26.375 % of 218 EUR). Net return: about 5,865 EUR, net final capital: about 41,865 EUR. With contributions at the start of each month (in advance): 42,027 EUR. If you invested the same sum all at once: 36,000 x 1.0025^120 = 48,577 EUR (since interest acts on the full amount from the first month).
Calculation Example
300 EUR/month, 3% interest, 10 years. Paid in: 36,000 EUR. Gross final capital: 41,922 EUR. Interest yield: 5,922 EUR. Tax with a 1,000 EUR allowance per year: approx. 58 EUR (only years 9 and 10 exceed it). Net: approx. 41,865 EUR.
