For many people in Switzerland, the pension fund represents their single largest financial asset. Occupational pension provision plays a central role in maintaining living standards in retirement. Yet not all pension funds are equal – the differences between institutions are considerable and carry significant financial consequences. For insured members, understanding the quality of their own scheme has never been more important.
Employers, too, have reason to pay close attention. "The pension fund is a component of total compensation and can serve as a long-term incentive for employees to remain with a company," says Erik Wirz of Wirz & Partners Executive Search. From an employer's perspective, occupational pension provision is not merely a statutory obligation. A modern solution signals care and foresight.
Many companies still have room to improve in this area. "Some SMEs end up with a pension solution almost by accident – many managing directors give it little thought," says Willi Thurnherr, occupational pension expert at Thurnherr Consulting. They are absorbed in running their business and tend to regard pension matters as a burden.
Significant differences also exist in the voluntary, above-mandatory components of pension provision. An unattractive benefits package can prove a serious disadvantage in recruiting senior executives, says headhunter Wirz. Candidates at the top of the market calculate carefully and factor pension arrangements into their decisions.
For employees more broadly, researching the terms of their own pension fund is worthwhile. It offers insight into how an employer treats its people and what retirement income can realistically be expected. The information becomes particularly relevant when considering a change of employer or making voluntary additional contributions.
Annual reports and fund websites are the primary sources. Wirz also recommends comparison platforms such as Pensionskassenvergleich.ch by Weibel Hess & Partner, as well as bank-run pension comparisons. He further points to the fee-based Swiss Pension Fund Rating at SPKR.ch.
The following metrics allow a fund to be assessed relative to its peers:
Funding ratio: The funding ratio indicates the extent to which a pension fund's liabilities are covered by its assets. A ratio of at least 100 percent is the baseline requirement – higher is preferable. After several strong years on financial markets, most Swiss funds are well positioned. According to the 2026 industry study published by Swisscanto, the investment arm of Zürcher Kantonalbank, the average funding ratio of private-law Swiss pension funds stood at 119.6 percent at the end of last year – the second-highest level since 2000.
Should a fund's ratio fall below 100 percent, remediation measures become necessary and insured members may be required to contribute to the recovery. The ratio is currently influenced by the technical interest rate, which each fund sets independently. Funds applying a lower rate take a more conservative approach; those using a higher rate appear better funded on paper. The metric therefore has limits as a standalone indicator.
If a pension fund pays high interest rates, it is very likely that it is also getting a lot right in terms of its investment strategy, says expert Willi Thurnherr.
Conversion rate: The conversion rate is the factor applied to accumulated retirement assets at the point of retirement to determine the annual pension. A balance of CHF 700,000 at a conversion rate of 5 percent yields an annual pension of CHF 35,000. The Swisscanto study puts the average conversion rate at retirement age 65 at 5.26 percent across surveyed funds.
A conversion rate set too high results in pension payments that exceed what the fund can sustainably finance, effectively redistributing wealth from active members to retirees. In response, many funds have reduced their rates in recent years – 17 percent did so this year, though that is markedly fewer than in 2019 and 2020, when nearly half of all funds made cuts.
Thurnherr urges context when interpreting this figure. A low conversion rate can be offset by strong crediting of retirement assets, he notes. Christian Heiniger, pension expert at Willis Towers Watson, adds that the conversion rate matters most for those approaching retirement. For a 45-year-old with two decades of working life ahead, it is a secondary concern – the rate may change multiple times before it becomes relevant, depending on longevity trends and the interest rate environment.
Employer contributions: The level of employer contributions is another indicator of a fund's quality. Under Swiss law, employers must cover at least half of the savings contributions towards occupational pension provision. Many go further, contributing up to two thirds.
Crediting of retirement assets over the past three to five years: The interest credited annually to retirement assets is among the most consequential metrics for assessing a pension fund. The decision rests with each fund's board of trustees and varies significantly across institutions. According to the current Swisscanto study, the average real interest rate credited to active members' retirement assets last year – after adjusting for inflation – was 4.6 percent, the highest in 25 years.
Thurnherr recommends assessing the crediting rate over a multi-year period rather than in isolation. Heiniger notes that the priority for insured members should be to accumulate as much retirement capital as possible. Since many will not retire with their current employer, the balance travels with them when they move.
Over a five-year period, the difference in returns between the best-performing and weaker pension funds amounted to as much as 26 percentage points, according to the study. Thurnherr recommends considering the returns on retirement assets over a longer time horizon.
It is equally important that a fund be able to pass on investment returns to its members. Collective and joint foundations operate under stricter regulatory constraints in this regard and may only distribute freely once their fluctuation reserves are fully funded. Last year, that condition was met in the majority of cases: funds passed on an average of 78 percent of returns achieved to their members, according to Swisscanto.
Investment strategy and performance: Investment performance and the crediting of retirement assets are closely linked. A fund that credits consistently high interest rates is, in all likelihood, doing something right in its investment approach, says Thurnherr. According to the Swisscanto study, 93 percent of funds tie their crediting rate to investment returns. The top decile over five years credited an average of 6.7 percent in 2025; the bottom decile, 3.4 percent.
"The importance of pension fund performance is frequently underestimated," says Heiniger. A fund can only distribute what it earns – and the level of savings contributions is a function of employer and employee decisions, not of the fund itself.
Some funds continue to carry a high allocation to bonds, which Thurnherr views critically given the current rate environment. The Swisscanto study concurs, describing fixed income as a drag on performance. The highest-performing funds held an average bond allocation of 18 percent; among the weakest, that figure was roughly double.
Ratio of active members to retirees: The proportion of retirees relative to active contributors is a further quality indicator. A high retiree share constrains the fund's investment flexibility, typically resulting in lower returns. "Where the ratio is unfavourable, lower crediting rates should be expected over the long term – guaranteed pension obligations to retirees tend to push investment strategy in a more conservative direction," says Thurnherr.
