Scalable Capital vs flatex — which broker is better?

Pros

• Free savings-plan executions from EUR 1 with fractional amounts, across more than 2,700 ETFs, 4,500 shares and 3,800 funds - the deepest catalogue in Europe.
• PRIME+ at EUR 4.99 a month makes trading a fixed cost rather than a variable one; commission-free orders from EUR 250 on EIX break even at roughly five trades a month. Purchases of PRIME ETFs (Amundi, iShares, Vanguard, Xtrackers) from EUR 250 on EIX are free on the FREE Broker as well, so they do not count towards that.
• Holds its own full ECB banking licence since September 2025 and custodies client securities itself, with cash covered to EUR 100,000 and PRIME+ balances spread across partner banks for wider statutory coverage.
• 2.60% p.a. on the Scalable Overnight cash account, paid monthly - on unlimited cash, with or without PRIME+.
• More than 3,800 mutual funds tradable without the front-end load, which is unusual at a flat-fee broker and useful for anyone holding legacy fund positions.
• German residents get Abgeltungsteuer, solidarity surcharge and church tax withheld and remitted automatically, with annual tax certificates issued.
• Broker, cash account, robo-advisor (Scalable Wealth) and a securities-backed credit line all sit behind one login, which is a genuine consolidation argument.

Cons

• Since 1 September 2026 gettex orders cost up to EUR 1.99 on every plan, up from EUR 0.99, which wiped out the PRIME+ commission-free advantage that made the subscription compelling on that venue.
• Only three trading venues - EIX, gettex and Xetra - with no direct access to US or other foreign exchanges, so you buy foreign shares through a German quote rather than on their home market.
• On EIX, Scalable is the single market maker on the venue it routes you to by default, which is the same broker-as-counterparty conflict the post-PFOF industry inherited.
• Euro-only accounts with no multi-currency balances and no itemised FX charge, so the true cost of a foreign share purchase is not visible on the contract note.
• No telephone support: chat and email only, with slow replies and delayed tax documents the most common complaint in user reviews.
• Fractional trading works in savings plans but not in ordinary lump-sum orders, and there is no demo account.

Pros

• EUR 5.90 flat commission on German, US, Canadian and other foreign orders with no percentage component up to EUR 40,000 — a EUR 10,000 trade costs the same as a EUR 1,000 trade
• All ETF and fund savings plans execute at EUR 0.00 commission with over 5,000 plans available and no cap on the savings rate
• No custody fee, no account fee, no inactivity fee, and free incoming and outgoing depot transfers
• Genuine spot crypto in around 25 coins at 0.6%–0.7% all-in, held inside the regulated German bank rather than as an ETN wrapper
• Full German banking licence under BaFin and Bundesbank supervision, with an MDAX-listed parent (flatexDEGIRO SE, ticker FTK) publishing audited accounts and over EUR 100 billion in customer securities under custody
• Tax-simple in both markets it serves: automatic German Abgeltungsteuer withholding and automatic Austrian KESt settlement at 27.5% on flatex.at
• Free foreign-currency sub-accounts, so USD or CHF proceeds can be held rather than converted back at a spread every time
• Fast onboarding — flatex advertises a five-minute fully digital account opening, and no minimum deposit applies

Cons

• 0.00% p.a. credit interest on cash balances. Competitors pay 1%–1.75% on the settlement or call account, so an investor holding EUR 20,000 in cash gives up EUR 200–350 a year that never shows up in any fee table
• Currency conversion costs an absolute margin of USD 0.0040 per euro — roughly 0.35% — which is worse than Consorsbank's published USD 0.0030 and far worse than a multi-currency specialist
• No Eurex or US options and futures trading at all. Certificates, knock-outs and Société Générale CFDs are the only leveraged instruments on offer
• Real-time quotes are metered: 25 free per month plus 10 per executed order, then EUR 0.01 per query, and the professional flatex trader 2.0 platform costs EUR 15–39 a month on top
• The EUR 5.90 floor makes flatex expensive for small orders — a EUR 300 purchase pays about 2% in commission before venue costs, where a EUR 1 neobroker charges 0.3%
• Direct foreign market access is narrow: US, Canada, Euronext, Vienna, Zurich and Milan (sell only). There is no direct London, Tokyo, Hong Kong or Nordic access, and stock savings plans cost 1.00% of the rate
