Flatex vs Scalable Capital — traditional depot bank vs hybrid neo-bank

Flatex (founded 1999, Kulmbach) and Scalable Capital (founded 2014, Munich) are both BaFin-regulated DACH-focused brokers — but they sit at opposite ends of the spectrum. Flatex is a traditional full-service Direktbank: 12+ German exchanges, Wien direct access, real Stop-Limit/OCO orders, Eurex options, telephone support. Scalable is a hybrid neo-bank: app + web, gettex/Xetra, two-tier subscription model (Free at €0.99 per order; PRIME+ at €4.99/month with €0 commission).

The honest framing: Flatex is built for users who place a few large orders per year and value execution depth. Scalable is built for users who place many small-to-medium orders per month and value cost predictability via the flatrate. The choice depends on monthly trading frequency.

When Flatex is the better pick

You trade Austrian stocks (Wien) regularly. Flatex offers direct Wiener Börse access. Scalable does not — Wien-listed stocks must be traded via gettex's secondary listing where spreads are 0.10–0.30 % wider. For OMV, Verbund, Erste at €5 000+ orders, the spread savings on Flatex are €5–€15 per trade.

You handle large orders (€10 000+) on illiquid mid-caps. Flatex's smart-routing across Tradegate, Quotrix, Xetra, regional venues finds the best price; Scalable routes to gettex/Xetra only. On a €25 000 mid-cap order, the price-improvement on Flatex's smart-routing can save €30–€80 versus a single-venue execution.

You need real order types — Stop-Limit, OCO, Trailing-Stop on multiple legs. Flatex supports complex order structures including bracket orders. Scalable's order types are basic (Market, Limit, Stop-Loss).

You trade Eurex options regularly. Flatex offers full Eurex retail access — DAX/Bund options and futures. Scalable does not offer options.

You value telephone support and a long-tenured German Direktbank brand. Flatex has 25+ years of Direktbank experience and offers full telephone customer service. Scalable's support is chat-first.

When Scalable Capital is the better pick

You trade more than 6 orders per month. Scalable PRIME+ at €4.99/month gives you €0 commission on every order on gettex and Xetra — break-even at 6 orders versus the €0.99 pay-per-trade Free tier. Flatex stays at €5.90 + venue fees per order regardless of frequency. For active investors, the math heavily favors Scalable PRIME+ above 6 orders/month.

You want fee-free ETF savings plans on hundreds of ETFs. Scalable offers €0 savings plans on >2 000 ETFs from €1 minimum. Flatex's savings plans cost €1.50 per execution outside the partner-program ETFs (a smaller catalog). For a 3-fund Bogleheads setup, Scalable saves ~€450/year over Flatex.

You want web + app + desktop unified. Scalable's interface stack is modern, fast, and identical across web/app. Flatex's WebFiliale is functional but feels generationally older — the order ticket and chart interactions are less polished.

You hold idle cash and want a yield. Scalable PRIME+ pays approximately 2.6 % p.a. on idle EUR cash (rate variable). Flatex pays 0 % on the trading account; their separate Tagesgeld product has its own terms and currently lower rate.

You want crypto + fractional shares in one BaFin-regulated account. Scalable supports both. Flatex does not offer spot crypto and has limited fractional-share support.

Taxes — DACH specifics

Germany — both steuereinfach. Flatex and Scalable both withhold 25 % KESt + 5.5 % Soli + optional Kirchensteuer at source. Both apply Sparerpauschbetrag automatically. Loss carry-forward is per-broker.

Austria — Flatex Austria is austriakonform; Scalable is not. Flatex Österreich (operated via flatexDEGIRO Bank AG, Austrian branch) automatically withholds the Austrian 27.5 % KESt at source — no FinanzOnline reporting for ordinary stock trades. Scalable in Austria is a non-austriakonformer Broker: every transaction must be self-reported via Anlage E1kv. Vorabpauschale, dividend tax credits, US W-8BEN withholding all need manual treatment.

Vorabpauschale 2026: Both apply Vorabpauschale automatically on January 2 by debiting the cash account. Both expect ~0.5–1 % of accumulating ETF position value in cash at year-end.

Quellensteuer on US dividends: Both file W-8BEN; the standard 15 % US withholding is creditable against German KESt automatically. For Austrian Flatex clients, the credit is also automatic.

Eurex-options tax handling: Flatex supports Eurex options; Eurex options gains/losses are subject to the controversial €20 000 Verlustverrechnungstopf cap. Scalable does not offer options, so this consideration does not apply.

Cost example — €15 000 active investor over 10 years

Profile: 1 monthly ETF savings plan at €100, 8 manual one-off purchases per month at €500 each, average €5 000 idle cash buffer.

ItemFlatexScalable PRIME+
120× savings-plan execution€180 (€1.50 each)€0
960× manual orders €500€5 664 (€5.90 each)€0
Venue fees€960 (40× €1 venue)€0
PRIME+ subscription (10 yrs × 12 mo)€0€598
Cash interest (€5 k × 10 y × rate)€0+€1 300 (2.6 %)
Net 10-year cost€6 804−€702

The €7 506 difference is enormous — almost half the original €15 000 capital — and entirely explained by the per-order commission gap at this trading frequency. For an 8-orders-per-month trader, Scalable PRIME+ is structurally the right answer.

The Flatex case becomes competitive only at low trading frequency (1–2 orders/month) where the PRIME+ subscription cost outweighs the savings, OR at large illiquid mid-cap orders where Flatex's smart-routing saves more in spread than the commission gap. For occasional Wien-stock trading, Flatex Austria's austriakonformer status alone justifies the choice for AT residents.

Verdict by investor profile

Beginner with monthly savings plan only

Pick: Scalable Free. The €0.99 commissions for occasional manual buys plus €0 savings plans are good enough; PRIME+ is overkill at this scale. Flatex's €5.90 commissions are punitive for small contributions.

Active investor 8+ manual orders/month

Pick: Scalable PRIME+. The flatrate breaks even at 6 orders and saves real money for anyone running monthly rebalances or satellite buys. Flatex is structurally too expensive at this frequency unless you trade illiquid mid-caps where execution quality dominates commission.

Austrian resident with €100 k+ portfolio

Pick: Flatex Austria. The austriakonformer status alone justifies the choice — manual FinanzOnline reporting on every trade quickly becomes more expensive than the commission difference vs Scalable. Pair with Scalable Free if you want fee-free EU savings plans on the side.

Eurex options trader

Pick: Flatex (or upgrade to IBKR). Scalable does not offer options. Flatex supports retail Eurex access; for occasional options strategies it is the right answer.

Wien-stock investor

Pick: Flatex. Direct Wien access for OMV/Verbund/Erste with proper limit-order support beats Scalable's gettex routing for these specific instruments.
