It involves estimating future expenses, understanding various retirement accounts, and developing a savings strategy that accounts for inflation, taxes, and investment growth.

Replacement Ratio: Percentage of pre-retirement income needed
Safe Withdrawal Rate: Annual withdrawal percentage (typically 3.5-4%)
Time Horizon: Years until retirement

Common Retirement Planning Mistakes
Starting Too Late
The power of compound interest means starting early has exponential benefits. Even small contributions in your 20s can outperform larger contributions started in your 40s.
Underestimating Expenses
Many retirees find their expenses don't decrease as much as expected. Healthcare costs, travel, and hobbies can maintain or increase spending levels.
Ignoring Inflation
What costs $50,000 today will cost about $90,000 in 20 years with 3% inflation. Plan for purchasing power, not just dollar amounts.
Not Maximizing Employer Match
Employer 401(k) matching is free money. Always contribute enough to get the full match before investing elsewhere.
