Retirement Savings Plan (RSP)

Tax-advantaged retirement savings structure used to encourage long-term retirement accumulation through regular contributions and investment growth.

On this page

A retirement savings plan (RSP) is a tax-advantaged savings structure designed to help individuals accumulate assets for retirement over time.

The term is broader than any one country’s exact account label. What matters is the core function: contributions receive favorable tax treatment, the assets grow over time, and the structure is meant to support retirement income later.

Why It Matters

Retirement savings plans matter because they shape:

  • how much savers contribute

  • when taxes are paid

  • how long money can compound

  • how retirement withdrawals are treated

That means the plan design itself changes behavior, not just the investment return inside the account.

  • IRA: One specific retirement savings structure in the U.S.

  • 401(k) Plan: Employer-sponsored retirement savings structure.

  • Retirement Fund: Broader pool-level concept that retirement savings plans feed.

  • Nest Egg: Informal label for the accumulated savings outcome.
