How your pension is built
Two factors: average yearly income over your career and completeness of contribution years (missing years cut the pension by roughly 1/44 each). Employed people contribute automatically; the non-working spouse can be covered via the working partner above a threshold – but check, gaps here are common.
What internationals should do
Order your individual account statement (Kontoauszug) every few years – free, and errors are fixable. Leaving Switzerland? Depending on nationality and treaties, AHV may be paid abroad or (for some non-treaty states) refunded – clarify BEFORE departure.
Plan with real numbers
Your AHV statement plus pension fund certificate beat every generic estimate.

How the AHV pension is calculated
Two things determine your pension: the number of contribution years and your average annual income across them. A full contribution record means paying in every year from age 21 (20 for the year of the 21st birthday under current rules) until retirement age. Anything less reduces the pension proportionally – roughly one forty-fourth per missing year for men and women with a full career expectation.
The pension is capped: even very high earners receive no more than the maximum single pension, and a married couple together receives no more than 150 % of the maximum single pension. This ceiling is why higher earners rely far more on the second and third pillars.
Contributions are owed on all earned income without an upper limit, which means high earners pay considerably more than their eventual pension reflects. The AHV is explicitly redistributive by design – knowing this prevents the common assumption that a high salary automatically produces a high state pension.
Gaps: how they arise and what can still be fixed
The most common causes are years spent abroad before arriving in Switzerland, studies without contributions after age 21, and periods of non-employment without registering as a non-working person. Non-working residents – including accompanying spouses without a job – are liable for minimum contributions, and missing them creates gaps that look invisible until retirement.
Order the individual account statement (Individuelles Konto) from your compensation office. It is free, arrives within weeks and lists every recorded year. Gaps within the last five years can usually still be paid retroactively; older ones generally cannot.
For married couples there is one partial safeguard: contributions of a working spouse can cover a non-working spouse if the working spouse pays at least twice the minimum contribution. This does not apply to unmarried couples, which is one of the concrete financial asymmetries of cohabitation.
Early or deferred retirement – the arithmetic
Drawing the AHV early permanently reduces the pension for life, and the reduction is not recovered later. Deferring it increases the pension, also permanently. Both adjustments are actuarial, meaning the system is roughly neutral over an average lifespan – which shifts the question from arithmetic to personal circumstances.
Deferring makes sense when other income covers the gap and life expectancy is good; drawing early makes sense when the money is needed or health is uncertain. Neither is universally better, and advice presenting one as obviously correct should be treated with caution.
One practical detail: early withdrawal also means AHV contributions may still be owed until ordinary retirement age if you continue working. Checking this before deciding avoids an unpleasant discovery in the first year.
