Tax drag is the difference between the final portfolio value without and with the annual Vorabpauschale. It shows how much wealth is lost due to ongoing taxation during the accumulation phase.
For a 20-year ETF savings plan with 7 % annual returns, tax drag amounts to roughly 2-4 % of the final portfolio value. The exact figure depends on the Basiszins (base rate) and the Teilfreistellung (partial exemption).
Yes, for tax purposes each monthly purchase is treated as a separate lot with its own acquisition cost. When selling, the FIFO (first in, first out) principle applies.
Yes. Even a 2 % annual increase can boost the final portfolio value by 15-20 % over 20 years. The additional contributions benefit from the compound-interest effect.
The MSCI World has historically delivered about 7-8 % before inflation. A more conservative estimate is 5-6 % after inflation. Past returns do not guarantee future results.

Calculate now →An ETF-Sparplan (savings plan) invests a fixed amount each month into one or more ETFs. Thanks to the cost-averaging effect (Cost-Average-Effekt), you buy more shares when prices are low and fewer when prices are high. Over long periods, this smooths out the average purchase price.
Most German brokers offer ETF savings plans starting from EUR 25 per month, many of them without execution fees. The key levers are the monthly contribution (Sparrate), the investment period, and the expected return.
Most savings plan calculators only show the final wealth before taxes. In reality, German investors pay the Vorabpauschale (advance lump sum) on accumulating ETFs every year. This annual tax reduces the capital available for compounding — the so-called tax drag (Steuerbremse).
Over a 20-year savings plan with a 7% return, the tax drag can amount to 2-4% of the final wealth. That may sound small, but on EUR 200,000 in final wealth it means a difference of EUR 4,000-8,000.
