Building-Savings vs. ETF Plan in 2026: Is Bausparen Still Worth It?

The Bausparvertrag is one of the most German financial products of all: 28 million contracts are active in Germany, the market share of Schwaebisch Hall, BHW and LBS has been stable for decades, and an ad brochure hangs in every second family living room. At the same time the ETF monthly plan has exploded in the last ten years: more than 8 million plans on the MSCI World or All-World, often starting at 25 euros per month. Both promise long-term wealth building, but they work completely differently. This article breaks down how a Bausparvertrag really calculates, which hidden costs hide between the advertising and the small print, how state subsidies actually work — and when the ETF plan wins on the math.

How a Bausparvertrag mechanically works

A Bausparvertrag is not a single product but a combined contract: a savings plan plus a pre-approved annuity loan. You set a so-called Bausparsumme, for example 50,000 euros. This sum is the target you will both save and later borrow — typically 40 to 50 percent saved equity, the rest as the Bauspar loan. The whole mechanic runs through three clearly separated phases, and each one has its own rules.

Important to understand: in advertising the Bausparvertrag is sold as a savings product (safe, state-subsidised), but in the contract it is primarily a credit product preceded by a savings discipline. The low credit interest on your savings is the price the Bausparkasse pays for being able to later allocate you a cheap, guaranteed loan.

• Savings phase (Ansparphase): You pay in monthly, typically 3 to 5 per mille of the Bausparsumme (so 150 to 250 euros per month for a 50,000 euro contract). The balance earns a very low credit interest, often 0.1 to 1.0 percent. Depending on the tariff this phase lasts 6 to 10 years.
• Allocation maturity (Zuteilungsreife): The contract becomes allocation-ready once three conditions are met — a minimum saved balance (often 40 to 50 percent of the Bausparsumme), a minimum duration, and a sufficient rating number. Only then are you entitled to the Bauspar loan. If you don't want the loan, you can simply withdraw the balance.
• Loan phase (Darlehensphase): The remaining Bausparsumme is paid out as an annuity loan with an interest rate already locked in at contract signing, typically 2.0 to 3.0 percent (as of 2026). Repayment runs 7 to 12 years with high monthly instalments (often 6 to 8 per mille of the Bausparsumme), because the loan must be paid off quickly.

The two interest rates — the actual secret

Every Bauspar tariff has two fixed rates: the credit interest on your savings and the loan interest in the loan phase. Both are agreed at contract signing and stay unchanged until the end of the contract. That's the actual trick: the credit interest is extremely low at 0.1 to 1.0 percent (well below daily-money accounts), but in exchange the loan rate of 2.0 to 3.0 percent is guaranteed for 10 to 20 years — regardless of what the market does. In a high-rate cycle (such as 2023 and 2024) that suddenly became a real advantage again.

In other words: signing a Bausparvertrag is essentially buying interest-rate insurance on the future. If mortgage rates are at 6 percent in 8 years and your guaranteed loan rate is 2.5 percent, you have won. But if they're at 2 percent, foregoing credit interest during the savings phase did not pay off — and you would have been better off with a classic mortgage.

The hidden costs

Looking only at the interest rate misses the most expensive items of a Bausparvertrag. Three fees materially shape the real return:

• Abschlussgebuehr (acquisition fee): 1.0 to 1.6 percent of the Bausparsumme, due at the start. For a 50,000 euro contract that's 500 to 800 euros instantly deducted from your balance. This fee never earns interest — it is lost even if the contract is later cancelled.
• Kontofuehrungsgebuehr (account-keeping fee): typically 12 to 24 euros per year over the entire contract. Sounds small but adds up to 200 to 500 euros over 20 years.
• Loan fee / Agio: some tariffs charge another 2 percent of the loan amount as a processing fee at payout. This is effectively a hidden interest surcharge on top of the loan rate.

Once the Abschlussgebuehr is folded into the savings-phase yield, the typical effective return is minus 0.2 to plus 0.3 percent per year — in real terms a loss against inflation. By comparison: a broadly diversified MSCI World ETF has delivered a long-term (1980 to 2025) average real return of around 6 to 7 percent per year after inflation.

State subsidies — the three levers

The strongest argument made by the Bausparkassen is state subsidy. It is real, but tied to income limits that many middle-class households exceed:

• Wohnungsbaupraemie: 10 percent on your own savings of up to 700 euros per year (single) or 1,400 euros (couple). Maximum therefore 70 or 140 euros per year. Condition: taxable income under 35,000 euros (single) or 70,000 euros (couple). Anyone earning more gets nothing.
• Arbeitnehmer-Sparzulage (employee savings bonus): 9 percent on capital-forming payments (VL) up to 470 euros per year, so a maximum of around 43 euros. Condition: taxable income under 17,900 euros (single) or 35,800 euros (couple) — limits that are unrealistic for most employed adults.
• Wohn-Riester (home pension): Riester subsidy applied to Bausparvertraege, with allowances and tax breaks during the savings phase. In exchange, the later self-use is taxed retroactively. Worth it only with very clear home-ownership intent and a matching family situation — rarely useful for childless singles.

The ETF alternative

An ETF monthly plan on the MSCI World or FTSE All-World invests automatically in 1,500 to 4,000 stocks globally each month. There is no interest guarantee, no state-supported savings book, no allocation. In return there are real return prospects, daily liquidity and total costs of typically 0.12 to 0.22 percent per year (TER). Volatility is high — minus 30 percent in a crash year is normal — but the long-term expectation after inflation and fees is 5 to 7 percent real.

Unlike a Bausparvertrag, an ETF plan is completely flexible: the savings rate can be changed at any time, payouts are possible at any time, and there is no requirement to use the money for real estate. What you don't get is a guaranteed cheap loan. Anyone planning a concrete building project within the next 3 to 5 years also runs a real sequence risk in the ETF: a crash shortly before the house purchase can cut the planned equity in half.

Worked example: 200 euros per month, 7 years

Take a typical comparison: 25 years old, single, saving 200 euros per month, 7-year horizon (end of a classic Bauspar savings phase). Our Bausparvertrag-vs-Sparplan tool lets you recalculate this with your own numbers — the order of magnitude is:

• Bausparvertrag: 16,800 euros paid in, 0.5 percent credit interest, minus 600 euros Abschlussgebuehr and 7x 18 euros account fee = around 16,700 euros final balance. Including Wohnungsbaupraemie (if eligible) add about 490 euros. Effective pre-tax return: around 0.1 to 0.8 percent per year.
• ETF plan: 16,800 euros paid in, 7 percent nominal return, TER 0.2 percent — final value around 21,500 to 22,500 euros (depending on the exact market path). Effective pre-tax return: around 6.8 percent per year, real after inflation about 4.5 to 5 percent.

The comparison is not entirely fair: an ETF plan can also end in a bad phase — anyone selling in mid-2022 would have had significantly less. But across rolling 7-year windows of the last 50 years, the MSCI World beat every Bauspar tariff in roughly 90 percent of cases.

When a Bausparvertrag actually makes sense

Despite the weak savings return, there are three constellations where Bausparen wins mathematically:

• A concrete construction or purchase plan in 3 to 8 years, low equity, strong desire for planning security: the guaranteed loan rate is real insurance against rising rates.
• Eligibility for Wohnungsbaupraemie (income below the limits) or a full VL employer contribution: every state subsidy lifts the return massively and can over-compensate the Abschlussgebuehr.
• Modernisation or renovation financing: smaller Bausparsummen (10,000 to 30,000 euros) are often cheaper and faster to access as a modernisation loan than classic bank loans.

When the ETF plan clearly wins

Mirrored, there are three constellations where the Bausparvertrag is hard to justify mathematically:

• Long horizon (15+ years) without a concrete real estate plan: every reasonable return estimate clearly favours the ETF — and over 15 years the sequence risk also shrinks substantially.
• Income above the subsidy limits (35,000 euros single, 70,000 euros couple): without the Wohnungsbaupraemie and VL subsidy the Bauspar advantage melts away very quickly.
• Need for daily liquidity: ETF shares can be sold on every trading day. A Bausparvertrag is effectively frozen during the savings phase, and early termination typically costs 1 percent of the Bausparsumme.

Frequently asked questions

Is a Bausparvertrag worth it as a savings vehicle for my child?

Rarely. If the savings goal is later education or a car (not real estate), the only real advantage — the guaranteed low-rate loan — disappears. The 1.0 to 1.6 percent Abschlussgebuehr eats almost all of the first 1 to 2 years' low credit interest. A simple MSCI World ETF plan at 25 euros per month is usually the clearly better choice for building a child's wealth, even if the brochure suggests otherwise.

What happens to my Bausparvertrag if I never buy a house?

You can simply let the allocation lapse and have the balance paid out — you don't have to take the loan. The money is freely usable without re-taxation. But you lose the Abschlussgebuehr and only earned the very low credit interest during the savings phase. In hindsight that's an expensive, low-yield savings account. Anyone who received the Wohnungsbaupraemie may have to repay it if the money isn't used for housing — this applies mainly to younger savers.

Are Schwaebisch Hall, BHW and LBS equally good?

All three are established, BaFin-supervised Bausparkassen and fall under the Bausparkassengesetz (BauSpG) and deposit insurance. But tariff details differ a lot: Schwaebisch Hall is the market leader with a broad portfolio, BHW (a Deutsche Bank subsidiary) markets special repayment options more aggressively, and the LBS group is organised regionally and often paired with state credit programmes. More important than the brand is always the specific tariff — compare credit interest, guaranteed loan rate, Abschlussgebuehr and account-keeping fee.
