Early retirement: how much capital you really need

Many "living off your investments" calculations treat the state pension as if it didn't exist. That's fine as a safety assumption, but it produces discouraging numbers: if you spend €30,000 a year, the 4% rule says you need €750,000, and a more prudent 3.5% says over €850,000.

But if you've worked and paid contributions for twenty years or more, INPS will start paying you at some point. The problem isn't covering your spending forever: it's covering it until the first pension payment, and then topping up whatever the pension doesn't cover.

The two-pot method

1. The bridge

This pays for all your spending from the day you stop working to the day your pension starts. It has a clear, relatively short horizon, so it can be invested more cautiously and is spent down completely.

Basic formula, in today's euros: annual spending × years of bridge.

2. The top-up

From pension age onwards, this covers the difference between your spending and your net pension. It has a long horizon, potentially thirty years or more, and is sized using a safe withdrawal rate.

Basic formula: (annual spending − annual net pension) ÷ withdrawal rate.

A complete example

Marco is 45 and wants to stop working at 55. He spends €2,500 a month, or €30,000 a year. Using the INPS simulator, recalculated on the assumption that he stops contributing at 55, he estimates a net pension of about €1,600 a month over 13 payments, or €20,800 a year, starting at 67.

Accounting for the pension cuts the target by more than €230,000. And it's still a cautious estimate: the bridge assumes zero real return, and the top-up has twelve years to grow before it's needed.

The most common mistakes

• Using the "full" INPS estimate. The simulator assumes you work until pension age. If you stop at 55, twelve fewer years of contributions reduce the pension: always recalculate with your real exit date.
• Mixing up gross and net. Both the pension and your portfolio withdrawals should be compared after tax.
• Forgetting that the goalposts move. Pension age is linked to life expectancy and tends to rise. A bridge sized for 67 may need to cover an extra year or two: keep a margin.
• Investing the bridge like long-term money. If a big market fall hits in the first years and you're forced to sell to live, the damage is permanent. Money you need in the next few years deserves more stable instruments.
• Ignoring healthcare and surprises. They grow with age. An emergency fund kept separate from the plan means you don't have to touch the portfolio at the wrong moment.

Levers that reduce the capital you need

• Bridge income: even €800–1,000 a month from part-time work in the early years cuts the bridge by tens of thousands of euros.
• Voluntary contributions: in some cases INPS lets you keep paying contributions voluntarily after you stop working. They cost money, but can raise your pension or help you meet requirements you'd otherwise miss. It needs a case-by-case assessment.
• Supplementary pension: a pension fund can be drawn under its own rules and benefits from reduced tax on payouts. It can become part of the bridge or the top-up.

Every situation fits age, contributions, savings and tax together differently. Working out the combination that works for you takes your own numbers: you can start from the guide when can I retire or book a free call.
