Pension basics, explained without the jargon

A pension is a tax wrapper, not an investment

This is the single most useful thing to understand. A pension is a box with tax advantages. What sits inside the box — funds, shares, bonds, cash — is a separate decision.

That is why "my pension is doing badly" is usually a statement about the investments chosen inside it, not the pension itself.

Why the box is worth using

Money going in normally gets tax relief, growth inside is sheltered, and many employers add money on top. The trade is access: you cannot usually touch it until a set age.

• Contributions get tax relief at your rate, so a contribution costs less than its face value.
• Employer matching is an immediate uplift no savings account can match.
• Growth inside the wrapper is not taxed year to year.
• The trade-off is that the money is locked up until the scheme's minimum age.

The two kinds you will meet

Defined contribution schemes give you a pot; the outcome depends on contributions, growth and charges. Defined benefit schemes promise an income based on salary and service, and are usually worth keeping rather than transferring.

Where charges quietly matter

Charges are taken from the pot every year, so they compound against you exactly as growth compounds for you. Knowing your annual charge, and comparing it with a low-cost alternative, is a five-minute job with a decades-long payoff.
