Robo-advisors have made passive investing accessible to everyone in Spain: for €50 a month, you can have a globally diversified portfolio managed automatically, with much lower fees than actively managed funds. By 2026, three platforms will dominate the Spanish market: Indexa Capital, Finizens, and MyInvestor.
This guide compares their portfolios, fees, and historical returns in detail so you can make an informed decision.
What is a robo-advisor?
A robo-advisor is an automated investment platform that builds and manages a portfolio of index funds based on your risk profile. Unlike a traditional mutual fund, there is no active human manager making decisions—the algorithm periodically rebalances to maintain the target asset allocation.
The advantages are clear: total fees of 0.40–0.70% per year (vs. 1.5–2.5% for active management), immediate global diversification, and a 100% online process that takes just 10 minutes.

Historical annualized returns since inception. Future performance is not guaranteed. Approximate data as of May 2026.
Indexa Capital — The Most Transparent
Indexa Capital was the first robo-advisor in Spain (2015) and remains the industry leader. Its most aggressive portfolio (10/10) has historically generated an annualized return of 7.20%, while the moderate portfolio (6/10) averages around 5.40%.
- Total fee: 0.40% (>€100,000) to 0.59% (<€10,000), plus fund costs ~0.10%
- Minimum: €3,000 (or €150/month on a monthly plan)
- Funds: Vanguard, iShares, Amundi — the world’s best index fund providers
- Fund Transfers: Accepts tax-free fund transfers (key tax advantage)
- Pension plan: Also manages index-based pension plans
Best for: Investors seeking maximum transparency and the lowest total cost. The €3,000 minimum is the only barrier to entry.
Finizens — No minimum investment
Finizens is the option for those starting with little capital. With as little as €1, you can invest in a diversified global portfolio. Its Portfolio 5 (the most aggressive) has historically yielded 6.80% annually, and the moderate Portfolio 3, 4.50%.
- Total fee: from 0.49% (>€100,000) to 0.62% (<€10,000)
- Minimum: €1 — the most accessible on the market
- Funds: Primarily Vanguard
- Savings plan: Automatic contribution program starting at €50/month
- Finizens Plus: Integrated index-linked pension plan
Best for: Investors starting with small amounts or wanting to try passive investing without committing a lot of capital.
MyInvestor — The bank behind it
MyInvestor is the robo-advisor of Andbank, a real bank supervised by the Bank of Spain. This adds a layer of psychological security that some investors value. Its moderate portfolio has historically yielded ~5.50% annualized.
- Total fee: 0.56% all-inclusive
- Minimum: €150
- Unique advantage: Access to Vanguard and BlackRock funds directly from the same platform where you have your checking account
- Interest-bearing account: MyInvestor also offers 2.10% APR on its interest-bearing account
- Mortgages: MyInvestor customers have access to competitive mortgages
Best for: Investors who want everything in one place: checking account, index investing, mortgage, and retirement plan.
How much money do I need to get started?
An example with €10,000 over 10 years (historical returns, no guarantee):
| Robo-advisor | Portfolio | Hist. Return | Estimated final capital | Estimated gain |
|---|---|---|---|---|
| Indexa Capital | 6/10 | 5.40% | ~€16,869 | ~€6,869 |
| Finizens | C3/5 | 4.50% | ~€15,530 | ~€5,530 |
| MyInvestor | 5/10 | 5.50% | ~€17,081 | ~€7,081 |
Simplified calculation. Past performance is not a guarantee of future results. Does not include the tax impact of redemptions.
Taxation of robo-advisors
Robo-advisors in Spain invest through UCITS investment funds, which triggers the tax-free transfer benefit: you can move your money between funds without paying taxes until the final redemption. You only pay taxes (19–28% on gains) when you withdraw the money.
This is a huge advantage over ETFs, which are taxed every time you sell, even for rebalancing.
Robo-advisor vs. direct index funds?
If you have experience and want to save up to 0.20% more in fees, you can buy Vanguard funds directly through MyInvestor or through brokers like MyInvestor. But for most investors, the robo-advisor provides discipline and automation that justify the cost.
Conclusion: Which one should you choose?
- Starting with a small amount (<€3,000): Finizens (no minimum) or MyInvestor (from €150)
- You want maximum transparency and lower costs: Indexa Capital
- Want everything in one place: MyInvestor
- Long-term goal (+10 years): Any of the three—consistency matters more than the choice
The most important thing isn’t choosing the perfect robo-advisor, but getting started. The cost of not investing (inflation ~2–3% annually) is greater than the difference between these platforms.
