How Long Will My Money Last in Retirement?

On February 16, 2025 By newsroom Topic: Saving And Investing Money

To estimate how long your retirement savings will last, consider your total savings, annual expenses, and expected investment returns. Here’s how to calculate it and strategies to stretch your savings.


Quick Estimate

  • Savings Longevity Formula:
  • Total Savings ÷ Annual Expenses = Estimated Years.
  • Adjust for investment returns and inflation for accuracy.

  • Retirement Calculator: Tools like NerdWallet’s retirement calculator provide personalized estimates based on inputs like savings, expenses, and growth rates.


Common Retirement Withdrawal Strategies

  • The 4% Rule:
  • Withdraw 4% of your savings in the first year and adjust for inflation annually.
  • Example: $1 million savings $40,000/year.
  • Works best with a portfolio split 50% stocks and 50% bonds.
  • Note: Volatile markets may reduce its effectiveness.

  • Dynamic Withdrawals:

  • Adjust withdrawal amounts based on market performance.
  • Spend more in good years, less in down years.
  • Ideal for those comfortable with flexible spending.
  • Tip: Consult a financial advisor to set this up.

  • Income Floor Strategy:

  • Cover essential expenses (e.g., housing, food) with guaranteed income sources like Social Security, annuities, or bond ladders.
  • Use savings for discretionary spending to avoid selling investments in down markets.

Ways to Stretch Retirement Savings

  • Delay Social Security:
  • Benefits increase the longer you wait, up to age 70.

  • Optimize Investments:

  • Maintain a diversified portfolio of stocks and bonds.
  • Reduce fees by choosing low-cost funds.

  • Reduce Expenses:

  • Downsize your home or relocate to areas with a lower cost of living.
  • Cut discretionary spending.

  • Consider Part-Time Work:

  • Extend your savings by supplementing income.

  • Annuities:

  • Purchase an annuity to guarantee lifetime income for basic expenses.
  • Be cautious of fees and terms.

Key Considerations for Longevity Planning

  • Inflation:
  • Adjust withdrawal strategies to account for rising costs over time.

  • Healthcare Costs:

  • Factor in potential medical expenses, which can increase significantly with age.

  • Life Expectancy:

  • Plan conservatively for a longer-than-expected retirement.

Helpful Tools and Resources

  • Retirement Calculators: Gauge how savings rates, investment returns, and expenses impact savings longevity.
  • Financial Advisors: Help design personalized withdrawal strategies.

Pro Tip: Start early and revisit your plan periodically to adjust for market conditions and lifestyle changes.
