80% Retirement Rule (CH) – Explained
Why many retirees aim for around 80% of their prior income in Switzerland — and when that rule works (or fails). Use it to estimate your retirement budget and pension gap.
- 80% is a planning shortcut, not a guarantee — your real number depends on spending and taxes.
- Use it to set a target monthly retirement income, then compare with AHV + BVG.
- Adjust for Switzerland: housing, health insurance, and lifestyle costs can change the result.
The “80% rule” says you should plan to have about 80% of your pre-retirement income available in retirement. In Switzerland, people use this rule to estimate whether AHV (Pillar 1) and BVG (Pillar 2) will be enough — or whether they need Pillar 3 savings.
This guide explains where the 80% rule comes from, how to apply it, and what to do when it doesn’t fit your situation.
1. What is the 80% retirement rule?
The 80% rule is a rule of thumb: plan to replace roughly 80% of your income after you stop working. It’s meant to be a quick target for retirement planning — not an official pension promise.
If you earn CHF 6,000 net per month today, the 80% rule suggests a target of about CHF 4,800 net per month in retirement.
2. Why 80% can make sense (the logic)
The rule is based on the idea that many work-related expenses drop in retirement — while basic living costs remain. For some households, this leads to a slightly lower income need than during working years.
| Often lower in retirement | Often similar or higher in retirement |
|---|---|
| Commuting, lunches, work clothing | Health costs (premiums, out-of-pocket) |
| Saving for retirement (stops) | Leisure, travel, hobbies (time increases) |
| Mortgage payments may reduce over time | Housing (rent) may stay high in some areas |

3. When the 80% rule fails
The 80% rule breaks when your retirement spending isn’t “slightly lower” — for example:
- Low-income households: basic costs already consume most income, so you may need closer to 90–100%.
- High-income households: you may need far less than 80% if work income included heavy saving/investing.
- Expensive lifestyle plans: frequent travel, second home, or supporting family.
- Major housing change: moving to a higher-cost area or paying high rent long-term.
- Early retirement: you must finance more years before AHV/BVG start fully.
4. Switzerland-specific adjustments
In Switzerland, a few costs have outsized importance for retirement planning:
- Health insurance premiums: can remain significant even after retirement.
- Taxes: vary by canton and can change based on annuity vs lump sum.
- AHV + BVG structure: your “replacement rate” depends on contribution history and plan quality.
- Housing: rent vs mortgage, and what changes when work stops.

5. Simple calculator: your 80% target income
Use the rule in three steps. This is the “quick calculator” approach:
| Step | What to do | Example |
|---|---|---|
| 1 | Take your current net monthly income | CHF 6,000 |
| 2 | Multiply by 0.8 | CHF 4,800 |
| 3 | Adjust for your reality (housing, health, lifestyle) | e.g., CHF 5,100 if costs rise |

6. Compare target vs AHV + BVG (find your gap)
Once you have a target income (80% rule or your own budget), compare it to your expected pension income:
Pension gap = target monthly income − (AHV monthly + BVG monthly + other guaranteed income)

7. How to close a pension gap
If the 80% target is higher than your expected pension income, you have options. Common strategies include:
- Maximise Pillar 3a contributions (tax-advantaged).
- Invest via Pillar 3b for flexible growth.
- BVG buy-ins if you have a gap and it matches your withdrawal strategy.
- Work longer (late retirement) or adjust retirement age.
- Reduce expenses (especially fixed costs) to lower your target income.

8. FAQ: 80% rule Switzerland
Is 80% really enough to retire in Switzerland?
Sometimes yes, sometimes no. It depends on your fixed costs (housing, health insurance), taxes, and lifestyle plans. Use the 80% rule as a starting point, then verify with a retirement budget.
Should I use gross or net income for the 80% rule?
For personal planning, using net income is usually clearer because it reflects what you actually spend. If you use gross income, you must adjust carefully for taxes and deductions.
What if my AHV + BVG is far below 80%?
That’s a classic pension gap situation. Focus on Pillar 3a, consider BVG buy-ins (if suitable), invest via Pillar 3b, and review retirement age options. Start here: Pension Gap Switzerland.
