ETF depot or unit-linked insurance wrapper?
Neither is universally better. As a rule of thumb: under ~20 years, the lower-cost ETF depot tends to win. Over ~20 years, the tax-deferred wrapper often catches up and overtakes it, because rebalancing and fund switches inside a wrapper happen without tax leakage.
Side-by-side: the dimensions that actually move the outcome
| Dimension | ETF Depot (Broker) | Unit-Linked Insurance Wrapper |
|---|---|---|
| Typical TER + wrapper cost | 0.1 – 0.3% p.a. (TER only) | 0.3 – 2.0% p.a. (TER + wrapper) |
| Acquisition/setup cost | 0, ~25 € (broker bonus / fees) | Typically 2.5 – 4% of premium total, amortised over 5 years |
| Rebalancing inside the contract | Each rebalance is a taxable sale (Vorabpauschale + 25% KESt on realised gains) | Tax-free inside the wrapper, effectively +0.3 to +0.5% p.a. of compounding advantage over long horizons |
| Switching funds / changing strategy | Sell + rebuy = taxable event; loses ~25% of accumulated gains to tax each time | Free fund switches inside the wrapper; no tax, usually no cost |
| Flexibility (pause / reduce / stop) | Complete, pause or stop any time, no penalty | Pause/reduce possible; full surrender in early years usually punitive |
| Lock-in | None | Typical tax case requires 12 years + age 62 holding |
| Tax treatment of gains (DE resident) | Vorabpauschale annually; 25% capital gains + Solz on realisation; 30% Teilfreistellung on equity funds | Tax-deferred during accumulation; on payout: half of gain taxable at personal rate if 12y + age 62, else like depot |
| Portability if you leave Germany | Strong, moves with you; broker may close but assets stay yours | Mixed, wrapper-specific. Some products lose tax benefit; some stay; some restrict contributions for non-residents |
| Transparency of cost layers | Full. TER and broker fees public | Variable, requires reading the contract carefully |
| Inheritance / beneficiaries | Depot, passes via inheritance law, fully taxable | Wrapper, can name beneficiaries directly; specific tax treatment |
Why time horizon decides, short term vs. long term
Same monthly contribution, same market return assumption, same German tax residency throughout. The only thing that changes is the holding period, and whether you rebalance or switch funds along the way.
| Horizon | ETF Depot, net outcome | Low-cost wrapper (~1.0% p.a.), net outcome | Who tends to win |
|---|---|---|---|
| ≤ 10 years | Wins clearly, lower running cost, no setup amortisation drag | Behind, acquisition costs not yet recovered | ETF depot |
| 10 – 20 years | Still typically ahead, but the gap shrinks the more you rebalance or switch | Closing the gap fast thanks to tax-deferred rebalancing and free fund switches | Close, usually depot, sometimes wrapper |
| ≥ 20 years | Tax drag on rebalancing + Vorabpauschale compound against you year after year | Tax deferral + free switches + half-rate tax at payout (12y + age 62) start to dominate | Wrapper, often by a meaningful margin |
Illustrative pattern, not a guarantee. Real outcomes depend on actual wrapper cost (it only works if total cost stays ≤ ~1.0% p.a.), rebalancing frequency, fund switches, market path and personal tax. The longer the horizon and the more active the strategy, the more the wrapper's tax shield compounds.
Honest verdict, neither is better in absolute terms
ETF depot wins when… (short term)
- Your saving horizon is under ~20 years.
- You may leave Germany within 10–15 years.
- You want maximum flexibility (pause, reduce, redeploy, cash out).
- You prefer full cost transparency and direct control.
- Your contribution capacity may fluctuate significantly.
A wrapper wins when… (long term)
- Your saving horizon is 20+ years and you intend to actually hold.
- You're highly likely to stay in Germany for the full term.
- Total wrapper cost is genuinely low (≤ ~1.0% p.a. all-in).
- You will rebalance or switch funds, the wrapper does this tax-free.
- The 12y + age 62 half-rate tax case will apply at payout.
- You want beneficiary nomination and inheritance optimisation.
Rule of thumb: under ~20 years, the depot's lower running costs win. Over ~20 years, the wrapper's tax-free rebalancing and tax-deferred compounding usually win, provided the wrapper is genuinely low-cost. If the wrapper's all-in annual cost cannot be calculated from the contract, that already answers the question.
