The Importance of Retirement Planning: Start Early, Live Comfortably

Retirement planning matters because Social Security alone is designed to replace only part of your pre-retirement income. Starting early gives compound growth decades to work, so even modest, regular contributions — especially with an employer match — can grow substantially.

The power of starting early

Compound growth means your returns start earning their own returns. Here's a hypothetical illustration assuming a steady 6% annual return (real returns vary and are not guaranteed):

Start investing atMonthly contributionYears to age 65Approximate balance at 65
Age 25$30040about $597,000
Age 35$30030about $301,000
Age 45$30020about $139,000

The 25-year-old contributes $36,000 more than the 35-year-old but ends with roughly twice as much — that's compounding at work.

How much will you need?

A common rule of thumb is to plan for about 70–80% of your pre-retirement income each year, but your needs depend on housing, health and lifestyle. You can view your estimated Social Security benefits by creating an account at SSA.gov. Many people also use the "4% guideline" as a rough starting point for sustainable withdrawals, though it's a simplification, not a guarantee.

Steps to take now

  1. Enroll in your workplace plan and contribute at least enough to get the full match.
  2. Increase contributions by 1% each year or with every raise.
  3. Open an IRA if you don't have a workplace plan or want to save more.
  4. Choose diversified, low-cost investments — a target-date fund is a simple option.
  5. Check beneficiaries on every account.
  6. Avoid early withdrawals, which can trigger taxes and penalties.

It's never too late

If you're starting later, you still have options: higher contribution limits (catch-up contributions) are available from age 50, and working a few years longer or delaying Social Security can significantly improve your income.
