Pension or lump sum? The most important decision when retiring
March 31, 2025

arvy's Teaser: At retirement you face a decision you make exactly once — and can never reverse: take your pension fund as a monthly pension, a lump sum, or a combination? We're talking hundreds of thousands of francs and decades of retirement. Banks recommend lump sum (they want to manage it). Insurance companies recommend pension (they benefit from longevity risk). Here's the honest comparison — with real numbers, the breakeven calculation, and a decision framework for your situation.
Irreversible
This decision is for life. Once made, no going back. Most pension funds require registration 1–3 years before retirement. Plan ahead.
41%
Choose lump sum (FSO) — the most common choice
5.30%
Average conversion rate 2025 (was 6.74% in 2010)
CHF 144k
Less pension over 20 years due to conversion rate decline
How Switzerland decides
Around 40% of retirees choose the pension, 41% the lump sum, and 19% a combination. There is no standard solution — and that's right, because the best choice depends entirely on your personal situation.
Pension vs. lump sum: The direct comparison
| Pension | Lump Sum | |
|---|---|---|
| Payment | Monthly, for life | Once, entire amount |
| Taxation | As income, every year | Once, reduced special rate |
| Longevity risk | Pension fund bears it | You bear it |
| Investment risk | None (fixed pension) | You bear risk + opportunity |
| Flexibility | None | Full freedom |
| Survivors | Surviving spouse pension (60%) | Remaining capital inheritable |
| Inflation protection | Not guaranteed | Possible (depends on investment) |
| Wealth tax | None | Yes (capital is taxable wealth) |
The breakeven calculation: When does the pension win?
Example: Marco, age 65, CHF 500,000 pension fund capital
Option A: Pension
Conversion rate: 5.3%
Annual pension: CHF 26,500
Spouse pension: CHF 15,900 (60%)
Tax: as income, ~15–20%
Option B: Lump sum
Payment: CHF 500,000
Capital withdrawal tax: ~CHF 35,000–55,000
Net after tax: ~CHF 445,000–465,000
At 3% return: CHF 13,500/year income
Breakeven (simplified)
Pension: CHF 26,500 × 20 years = CHF 530,000 total received
Lump sum: CHF 465,000 + 3% return over 20 years = ~CHF 585,000 (incl. withdrawals)
At 3% net return the lump sum wins after ~18–20 years. At 0% return, the pension wins after ~17 years. The lower your investment return, the faster the pension wins.
Why the conversion rate changes everything
The average conversion rate has fallen from 6.74% (2010) to 5.30% (2025). At CHF 500,000 that's CHF 7,200 less pension per year. Over 20 years: CHF 144,000 less. The trend is continuing downward — making the lump sum option increasingly attractive for many.
The pension in detail
🟢 Planning certainty: You know exactly what comes in every month. No investment decisions, no market risk, no stress.
🟢 Longevity protection: However old you get — the pension flows for life. The risk of running out of money is zero.
🟢 Spouse pension: Your spouse typically receives 60% of your retirement pension — also for life.
🔴 No inflation protection: The pension is nominally fixed. At 2% inflation/year, your pension loses ~33% of purchasing power after 20 years.
🔴 Capital is gone: If you die early, the remaining balance doesn't go to your heirs.
🔴 Falling conversion rates: The rate will likely continue to decline.
🔴 Taxed annually: The pension is taxed as income every year. The lump sum is taxed once at a reduced rate — generally more advantageous.
The lump sum in detail
🟢 Flexibility: You decide when and how much you need. Adapt to your life, not the other way around.
🟢 Inheritance: What's left belongs to your heirs.
🟢 Return potential: Well-invested capital can generate significantly more over 20–30 years of retirement.
🟢 Tax advantageous: One-time capital withdrawal tax (typically 5–15% by canton) vs. annual income tax on the pension.
🔴 You bear the risk: Market crashes or poor investment decisions can deplete your capital.
🔴 Discipline required: The capital must last decades. The temptation to spend too much too early is real.
🔴 No longevity protection: If you reach 95 and the capital is depleted, you have a serious problem.
The combination: Best of both worlds
Strategy: Secure basic costs, take the rest as lump sum
Take enough as pension that your fixed living costs are covered together with AHV. Take the rest as lump sum — for travel, flexibility, inheritance, and as a buffer.
Marco's example: Fixed costs CHF 4,500/month. AHV CHF 2,400/month. Gap: CHF 2,100/month = CHF 25,200/year. At 5.3% conversion rate he needs ~CHF 475,000 as pension. The remaining CHF 25,000 he takes as lump sum.
For couples: One partner takes the pension (secures the base), the other takes the lump sum (flexibility, inheritance) — using the tax advantages of both options.
The staggered withdrawal strategy
The biggest tax lever at retirement: staggered withdrawal across multiple years, because capital withdrawal tax is progressive:
| Strategy | Tax (approx., Zurich, single) | Saving |
|---|---|---|
| All at once (CHF 500,000) | CHF ~55,000 | — |
| Split over 2 years (CHF 250k each) | CHF ~42,000 | CHF ~13,000 |
| PF + 3a + vested benefits over 3 years | CHF ~32,000 | CHF ~23,000 |
Reference values. Exact amounts depend on canton, municipality, marital status, religion. Use ESTV tax calculator for precise calculation.
Optimal sequence:
1️⃣ Year 1 (e.g. age 63): Withdraw 3a accounts (staggered)
2️⃣ Year 2 (e.g. age 64): Vested benefits account + further 3a accounts
3️⃣ Year 3 (e.g. age 65): Withdraw pension fund capital
Decision framework: What's right for you?
Choose pension if:
✅ You don't want to manage investments in retirement
✅ You have good life expectancy (family lives long)
✅ Your fund's conversion rate is attractive (>5.5%)
✅ You have little other wealth and need security
✅ You have no spouse, or they have their own good pension
Choose lump sum if:
✅ You have investment experience or a wealth manager
✅ Inheritance for your heirs matters to you
✅ Your fund's conversion rate is low (<5%)
✅ You have other reliable income sources
✅ You want flexibility for travel, property, or unexpected costs
Choose combination if:
✅ You want basic costs secured AND flexibility retained
✅ You want to optimise taxes (pension + staggered lump sum)
✅ Couple: one partner takes pension, other takes lump sum
Your roadmap: 5 years before retirement
5 years before: Read pension fund regulations — what withdrawal options does your fund permit? What's the conversion rate?
3–4 years before: Final pension fund buy-ins (3-year lock-up!). Stagger 3a accounts if not already done (one account per withdrawal year).
2–3 years before: Tax simulation — compare pension, lump sum, and combination in your canton. Check if relocating to a tax-friendly canton makes sense.
1 year before: Register capital withdrawal with the pension fund (check deadline in fund regulations). Fix investment strategy for the capital. Register for AHV pension.
Frequently asked questions
When does the pension outperform the lump sum in Switzerland?
At a conversion rate of 5.3% and 0% investment return, the pension wins after ~17 years. At 3% return, the lump sum wins after ~18–20 years. The longer you live and the lower your investment return, the more the pension benefits you. The combination is optimal for many.
How much tax can I save with staggered withdrawal?
Capital withdrawal tax is progressive. By distributing withdrawals across 2–3 years (pension fund, 3a, vested benefits), you can typically save CHF 13,000–23,000 on CHF 500,000. For couples: make withdrawals in different years, as both partners' withdrawals are added together in most cantons.
Can I take part as a pension and part as a lump sum?
Yes. Most pension funds allow a mixed option — and it's often the smartest solution. Under the mandatory BVG portion you must be able to withdraw at least 25% as lump sum; many fund regulations allow up to 100%. The combination strategy — pension for fixed costs, lump sum for flexibility — is optimal for many retirees.
What happens to my lump sum if I die early?
The remaining capital is inherited by your heirs. With a pension, your spouse receives the surviving spouse pension (60% of your retirement pension), but other heirs typically receive nothing after both partners have died. This is one of the main reasons lump sum is preferred by those who want to pass on wealth.
