Pensions and retirement accounts (the concept)

A pension or retirement account is a long-term pot designed to fund your later years. Governments encourage them with tax advantages, making them one of the most powerful wealth-building tools available. (For your country's specific accounts, see the country sections.)

Common building blocks worldwide

• Tax relief or tax-free growth: contributions may reduce your tax bill now, or grow and be withdrawn tax-free later — sometimes both.
• Employer contributions: many workplace schemes add money on top of yours — effectively free money.
• Access age: funds are usually locked until a set retirement age, which enforces long-term discipline.

Two broad types

• Defined contribution: you (and often your employer) pay in; the final pot depends on contributions and investment growth. The risk and reward are yours.
• Defined benefit: promises a set income based on salary and years of service. Increasingly rare, mostly older/public-sector schemes.

Why start early

Decades of tax-advantaged compounding mean early contributions do the heavy lifting. Capturing any employer match should usually come before other investing.

Key takeaway

Retirement accounts combine tax breaks, employer money, and long horizons — a rare trio. For most people they're the single most effective place to invest for the long term.
