The average Swiss 3a fund charges 1.28% per year in total fees. The cheapest digital providers charge 0.39%. Over 30 years, that difference costs you more than CHF 75,000. Most people never look at the numbers.
What is TER and why does it matter for your 3a?
TER (Total Expense Ratio) is the annual percentage your fund charges for management, administration, custody, and trading. It's deducted directly from your fund's value every day, so you never see a bill. You just get lower returns.
Here's the problem: TER doesn't tell the full story. Many providers charge additional depot fees, transaction costs, and currency exchange margins on top of the TER. Comparing funds on TER alone is like comparing apartments by rent without checking the utility costs.
What TER typically includes:
- Fund management fees (the biggest chunk)
- Administrative and operational costs
- Custody fees within the fund
- Audit and regulatory costs
What TER does NOT include:
- Depot/custody fees charged by the provider
- Buy and sell transaction costs (courtage)
- Currency exchange margins on foreign investments
- Swiss federal stamp duty (0.075% per trade)
- Entry and exit commissions
The only number that matters is your all-in cost: TER plus every other fee combined. That's what actually reduces your returns.
How much do 3a fund fees actually cost across providers?
The fee gap between the cheapest and most expensive Swiss 3a providers is enormous. We're talking about a 4x difference that compounds against you for decades.
0.39-0.48% all-in. Finpension (0.39%), VIAC (0.41%), frankly (0.44%). Passive index funds, no hidden charges.
0.70-0.91% all-in. CSA Mixta Index (0.80%), UBS Passive (0.89%), Swisscanto Passive (0.72%). Lower TER but depot fees add up.
1.00-1.76% all-in. UBS Vitainvest (1.33-1.66%), Raiffeisen (1.05-1.25%), PostFinance (1.09-1.23%). Active management rarely justifies the cost.
Here's a breakdown of real all-in costs for comparable high-equity funds (75-100% stocks):
Digital providers (passive):
- Finpension Global 100: 0.39% all-in (cheapest on the market)
- VIAC Global 100: 0.41% all-in
- frankly Extreme 95 Index: 0.44% all-in
Bank passive funds:
- Swisscanto Vorsorge 95 Passiv: 0.40% TER + 0.30% depot = 0.70% all-in
- CSA Mixta-BVG Index 75: 0.80% all-in
- UBS Vitainvest Passive 100: 0.24% TER + 0.65% depot = 0.89% all-in
Bank active funds:
- UBS Vitainvest World 100: 1.62% TER
- Raiffeisen Pension Invest Futura Equity: 1.25% TER + 0.80% buy/sell
- PostFinance Pension 100: 1.23% TER
Notice the UBS trick: their passive funds show a tempting 0.24% TER, but then charge 0.65% in depot fees. The total? 0.89%. Still cheaper than active funds, but nowhere near the 0.24% headline. Always check the all-in cost.
How do fees compound over 30 years?
This is where things get brutal. Small fee differences don't stay small. They compound exponentially against you for decades.
- Assumptions: CHF 7,258 annual contribution, 6% gross return, 30 years
- At 0.39% all-in (Finpension): ~CHF 510,000 final value
- At 0.75% all-in (UBS key4): ~CHF 475,000 final value
- At 1.20% all-in (average bank fund): ~CHF 425,000 final value
- At 1.50% all-in (expensive active fund): ~CHF 400,000 final value
- Cheapest vs. most expensive: CHF 110,000 difference
That's not a rounding error. CHF 110,000 is the price of choosing the wrong provider. And you made that choice (or didn't make any choice at all) in about 15 minutes when you opened your 3a account.
The compounding effect accelerates over time. In the first 10 years, the fee difference on CHF 7,258 annual contributions is maybe CHF 5,000-8,000. Annoying, but manageable. In years 20-30, when your balance is large, the same percentage fee is eating CHF 3,000-5,000 per year in absolute terms. Every year. For doing nothing different.
What hidden fees should you watch for?
TER is the fee everyone looks at. But several other costs fly under the radar and can add 0.20-0.65% to your true annual expense.
Depot and custody fees
Some providers charge a separate annual custody fee on top of the fund's TER. This is common with passive funds from traditional banks, where the low TER looks attractive but the depot fee brings the total back up.
Examples of hidden depot fees:
- UBS passive funds: 0.65% depot fee (on top of 0.24% TER)
- Swisscanto passive funds: 0.30% depot fee
- SZKB index funds: 0.40% depot fee
- GKB funds: 0.40% depot fee
- LUKB Expert funds: 0.25% depot fee
Digital providers like Finpension, VIAC, and frankly don't charge separate depot fees. Their all-in price is the all-in price. Period.
Currency exchange margins
When your fund buys foreign stocks (and most do, since Switzerland is only 3% of the global market), someone converts your CHF into USD, EUR, and other currencies. Some providers charge a margin on this.
VIAC, through WIR Bank, charges a currency exchange margin of up to 0.75% on foreign currency transactions (though netting reduces the effective cost). Finpension and frankly don't charge currency exchange fees. This cost doesn't show up in the TER and is nearly invisible.
Entry and exit commissions
Traditional bank funds can charge commissions when you buy or sell shares. UBS Vitainvest funds have a maximum entry commission of 2.50%. Migros Bank funds can charge up to 5% entry and 3% exit. Raiffeisen charges 3% maximum entry.
In practice, many banks waive these commissions for their own 3a clients. But "maximum" means they can charge it. Read the fine print.
Federal stamp duty
Switzerland charges a federal stamp duty of 0.075% on each fund transaction. This applies to everyone, but it matters more for actively managed funds that trade frequently. A passive index fund with annual rebalancing pays this once or twice. An active fund trading weekly pays it dozens of times.
Why do bank funds cost so much more?
Three reasons, and none of them are about delivering better returns.
Active management costs. Bank funds employ portfolio managers, research analysts, and trading desks. These people need salaries. The average active 3a fund charges 1.10-1.40% TER, while passive equivalents cost 0.25-0.48%. For a data-driven comparison of index vs active approaches, see our passive vs active fund analysis.
Distribution margins. Banks earn commissions (retrocessions) from fund companies for selling their products. Some funds have entry commissions of up to 5%, part of which goes to the selling bank. This creates an incentive to sell expensive products, not the best ones.
Legacy infrastructure. Traditional banks run 3a products through old systems designed decades ago. Digital providers built from scratch with modern technology, which means lower operational costs and lower fees for customers.
The uncomfortable truth: over 10-15 years, 80-90% of actively managed funds underperform passive index funds after fees. You're paying premium prices for below-average results in most cases.
How to compare 3a fund fees properly
Most comparison sites show TER only. That's misleading. Here's what you should actually compare.
Add the fund's TER to any depot or custody fees. This gives you the true recurring annual cost. For Finpension, it's 0.39%. For UBS Passive, it's 0.24% TER + 0.65% depot = 0.89%. Big difference from the headline TER.
Look at buy and sell costs (courtage). Some providers charge 0.40-0.80% per transaction. With monthly contributions, these costs add up. Digital providers generally charge nothing.
If your fund invests globally (it should), ask how currency conversion is handled and at what cost. Providers that use netting or don't charge FX margins save you 0.10-0.50% on the international portion.
These are often waived but can technically be charged. Check the fund's prospectus for the maximum allowed commission. If it says 5% entry, that's a red flag about the fund's overall cost philosophy.
Use a compound interest calculator with your expected contributions and returns. A 0.50% annual fee difference on CHF 7,258 contributions over 30 years at 6% gross return costs roughly CHF 35,000-45,000.

Which provider has the lowest all-in fees?
Based on current data for high-equity passive strategies (the optimal choice for most long-term investors):
Finpension
The cheapest. 0.39% flat management fee covers everything. No depot fees, no currency exchange charges, no transaction costs. Uses Swisscanto and UBS index funds underneath. Weekly rebalancing. Custom strategy options from 0-99% equity.
One price, no surprises. If pure cost optimization is your priority, Finpension wins.
VIAC
Close second. 0.00-0.44% depending on strategy. No depot fees. However, WIR Bank charges a margin on foreign currency transactions (up to 0.75%, reduced by netting). True all-in cost is slightly higher than the advertised rate for globally diversified portfolios.
Longest track record among digital providers (since 2017). Custom strategies available.
frankly
Third place, solid choice. 0.44-0.48% all-in using Swisscanto funds. No hidden costs. Backed by Zurcher Kantonalbank, which provides institutional backing and stability.
Maximum equity capped at 95% (vs. 99% at Finpension/VIAC). No custom strategies. The simplest option if you don't want to make choices.
UBS key4
Premium price for passive. 0.25% fund cost + 0.50% management fee = 0.75% total. Nearly double the cost of Finpension for a similar passive strategy.
UBS brand trust and in-branch support if that matters to you. But over 30 years, that 0.36% premium costs roughly CHF 30,000 on standard contributions.

Common mistakes with 3a fund fees
TER is just one piece of the puzzle. UBS's passive funds show 0.24% TER but charge 0.65% in depot fees on top. Always ask for the all-in annual cost, including depot fees, transaction costs, and currency exchange margins.
Over 10-15 years, 80-90% of active funds underperform passive equivalents after fees. The rare outperformers are nearly impossible to identify in advance. You're paying a premium for a coin flip with bad odds.
Transferring your 3a takes 2-4 weeks and costs nothing. You fill out a form, the new provider handles the rest. Every month you delay, you're paying 0.50-1.00% more than necessary. On a CHF 50,000 balance, that's CHF 250-500 per year.
"It's only CHF 7,258 per year, fees don't matter much." Wrong. Your balance grows over time, and fees compound against that growing balance. The last 10 years of your 3a career are when high fees do the most damage, because the balance is largest.
A beautiful app is nice. But a 0.40% fee difference matters infinitely more than dark mode or smooth animations. Choose based on costs first, features second, aesthetics last.
My take on 3a fund fees
After analyzing over 90 Swiss 3a funds and their fee structures, here's my blunt advice: fees are the single biggest lever you control in retirement investing. You can't control market returns. You can't predict which fund will outperform. But you can choose to pay 0.39% instead of 1.25%. That choice alone is worth CHF 75,000+ over a career.
My own approach: Finpension at 0.39% with maximum equity. I didn't overthink it. Lowest cost, passive index strategy, done. I review it once a year and spend the rest of my time on things I can actually influence.
If you're currently with a bank fund paying over 1%, switching is the highest-return financial decision you can make today. It takes 15 minutes.

Frequently Asked Questions
What is TER on a pillar 3a fund?
TER (Total Expense Ratio) is the annual percentage fee charged by a fund for management and operations. It's deducted from the fund's value daily. Swiss 3a fund TERs range from 0.24% (UBS passive) to 1.76% (EFG active). However, TER doesn't include depot fees, transaction costs, or currency exchange margins, so it understates the true cost of many funds.
Which 3a provider has the lowest fees in Switzerland?
Finpension currently offers the lowest all-in fees at 0.39% per year, which includes everything: management, custody, and transactions. VIAC follows at 0.41% and frankly at 0.44%. These digital providers cost 60-75% less than the average traditional bank fund (1.28% all-in).
How much do 3a fund fees cost over 30 years?
On CHF 7,258 annual contributions with 6% gross returns, paying 1.20% in fees (typical bank fund) instead of 0.39% (Finpension) costs roughly CHF 85,000 over 30 years. That's money subtracted from your retirement balance, compounding against you every year. Even a 0.36% difference (like UBS key4 at 0.75% vs. Finpension at 0.39%) costs about CHF 30,000.
Are low-cost 3a funds safe?
Yes. Finpension, VIAC, and frankly are all regulated by FINMA and use established custodian banks (UBS, Zurcher Kantonalbank, WIR Bank). Your assets are held separately from the provider's balance sheet, meaning they're protected even if the provider goes bankrupt. Low fees don't mean low safety. They mean low overhead.
Should I switch my 3a from a bank to a digital provider?
Almost certainly yes, if you're paying over 0.50% all-in. Transferring your 3a is free, takes 2-4 weeks, and doesn't trigger any tax events. The new provider handles the paperwork. On a CHF 50,000 balance, switching from 1.20% to 0.39% saves you CHF 405 per year, and that savings compounds.
