From what age to contribute to Pillar 3a?
Starting Pillar 3a early gains years of compound interest. Compando calculates the head start of starting at 25 versus 45, shows the tax advantage and how small amounts work long-term.
1. When can I contribute to Pillar 3a?
What matters is not the age, but an OASI-liable income from work with residence in Switzerland. As soon as someone earns income and pays OASI contributions, contributions to Pillar 3a are possible. This is already the case from the age of 18, for example:
- after vocational training
- with the first full-time job
- with a part-time job during studies or training
- in self-employment
Many Swiss working people only start with Pillar 3a between 30 and 40, although starting is possible much earlier.
Is an early start worth it?
Yes. The earlier the first contribution, the longer compound interest works and the more tax years add up. Those who start at 25 instead of 45 build up significantly more pension capital with the same contribution.
2. How much wealth do I build up with an early start?
Three people start at different ages and contribute the same total over the term into a balanced securities solution with 40 to 60 percent equity share. The calculation assumes a return of 3.5 percent per year after fees.
Person | Contribution per year | Term until 65 | Total contributed | Possible final assets |
|---|---|---|---|---|
Fabienne, 25 | CHF 2'400 | 40 years | CHF 96'000 | around CHF 203'000 |
Marc, 35 | CHF 3'200 | 30 years | CHF 96'000 | around CHF 165'000 |
Paula, 45 | CHF 4'800 | 20 years | CHF 96'000 | around CHF 136'000 |
All three contribute the same total, namely CHF 96'000. Nevertheless, Fabienne has around CHF 67'000 more pension capital at the end than Paula and CHF 38'000 more than Marc. The difference comes down to time alone: for Fabienne the compound interest effect works twenty years longer.
Regular small contributions over many years therefore bring more than late high contributions. With the Pillar 3a calculator from Compando you calculate what pension capital can build up over the years.
3. What advantages does Pillar 3a have in young years?
The time factor works in Pillar 3a in three ways at once: on taxes, on wealth building and on later home ownership.
Save taxes from the first year: Every contribution to Pillar 3a directly reduces taxable income. This annual tax saving adds up over the career years and starts with the first year of employment.
Wealth grows tax-free: During the term, no wealth tax or income tax on earnings apply in Pillar 3a. With longer investment duration, the compound interest effect works more strongly, especially with a securities solution with a higher equity share.
Home ownership possible early: Many young working people later use Pillar 3a for home ownership. Those who start early have already built up pension capital when buying a property, usable as equity or for pledging.
The most common error in thinking
«I'll start later when I earn more.» Many only start at 40 or 45, although especially the first ten to fifteen years make the biggest long-term difference for the final capital.
4. How much should I contribute as a young saver?
As much as your budget carries in the long term. Many believe that one must immediately contribute the entire maximum contribution. That is not so: there is no minimum contribution and no obligation to contribute, and how much you contribute you decide anew each year.
Even CHF 50 per month starts building wealth. With CHF 100 per month you use the compound interest effect regularly. From CHF 200 per month, substantial wealth builds up over the years. At the start of a career the marginal tax rate is low anyway, so the tax deduction gives back little. What counts in these years is the term.
More important than the perfect amount is to start at all and stay the course. A monthly standing order with small contributions that can be increased with rising income builds solid provision over the years, without financial pressure. With multiple 3a accounts, staggered withdrawal can also be used at retirement and the capital withdrawal tax lowered.
5. Who is Pillar 3a (not yet) suitable for?
Pillar 3a is worthwhile long-term, but not every life phase fits the start.
Life phase | Why caution can be advisable |
|---|---|
Students without OASI income | no 3a access possible |
First career years without emergency fund | liquidity reserve has priority |
Retirement in less than 5 years | short investment horizon |
High consumer debts at career start | debt reduction has priority |
Planned capital need in 1–3 years | restricted access |
With financial pressure, building up a liquidity reserve takes priority first. Tax optimisation brings little if the money is urgently needed.
Despite the restricted capital, Pillar 3a is not completely rigid: early withdrawals are possible for home ownership, self-employment or emigration. For home ownership, Pillar 3a can be pledged without dissolving the pension capital.
6. Conclusion: when should I contribute to Pillar 3a?
For the early start, three things count: time, an investment strategy with a securities share and consistent small contributions. Starting at 25 instead of 45, with the same contribution, around CHF 67'000 more pension capital arises. Time is the only one of the three you cannot make up later.
