Retirement Budget Planning: How to Make Your Money Last in Retirement

Retirement planning used to mean saving enough to last 15-20 years. Today, with life expectancies extending into the 80s and 90s, your retirement savings may need to last 25-30 years or more.

Here's how to build a budget that goes the distance.

Start With Your Income Sources

Before building a budget, list every income source you'll have in retirement:

  • Social Security: Your monthly benefit (check your statement at ssa.gov)
  • Pension: Monthly benefit if you have one
  • 401(k)/IRA withdrawals: Planned annual withdrawals
  • Investment income: Dividends, interest, rental income
  • Part-time work: If applicable

For most retirees, Social Security provides 40-60% of retirement income. The rest comes from savings and investments.

The 4% Rule

The 4% rule is a widely used guideline: withdraw no more than 4% of your portfolio in the first year of retirement, then adjust for inflation each year. This approach has historically sustained a 30-year retirement with a diversified portfolio.

Example: $500,000 portfolio → $20,000/year in withdrawals ($1,667/month)

The 4% rule is a starting point, not a guarantee. Low interest rates and longer life expectancies have led some financial planners to suggest 3-3.5% as a more conservative withdrawal rate.

Essential vs. Discretionary Spending

Divide your expenses into two categories:

Essential (non-negotiable):

  • Housing (mortgage/rent, property taxes, insurance, maintenance)
  • Healthcare (Medicare premiums, supplemental insurance, out-of-pocket costs)
  • Food and groceries
  • Utilities
  • Transportation
  • Medications

Discretionary (adjustable):

  • Travel and entertainment
  • Dining out
  • Hobbies
  • Gifts and charitable giving
  • Home improvements

Your essential expenses should be covered by guaranteed income (Social Security + pension). Discretionary spending comes from savings.

Healthcare: The Biggest Budget Wildcard

Healthcare is the largest and most unpredictable expense in retirement. A 65-year-old couple retiring today will spend an estimated $285,000 on healthcare costs over their lifetime (Fidelity, 2016 estimate) -- not including long-term care.

Budget for:

  • Medicare Part B premium: $121.80/month (2016)
  • Medigap or Medicare Advantage premium: $0-$200/month
  • Part D drug plan: $15-$60/month
  • Dental, vision, hearing: $1,000-$3,000/year out of pocket
  • Long-term care: Consider long-term care insurance or a dedicated savings fund

The Housing Decision

Housing is typically the largest expense in retirement. Key decisions:

Pay off the mortgage before retiring if possible -- eliminating a mortgage payment dramatically reduces your monthly income needs.

Downsizing can free up equity and reduce maintenance costs. Many Florida retirees find that downsizing from a family home to a smaller home or condo reduces housing costs by $500-$1,000/month.

Reverse mortgage: For homeowners 62+, a reverse mortgage can provide tax-free income while allowing you to stay in your home. It's not right for everyone, but worth understanding.

Inflation: The Silent Retirement Risk

Inflation erodes purchasing power over time. At 3% annual inflation, your cost of living doubles every 24 years. A retiree who spends $4,000/month at 65 will need $7,200/month at 89 to maintain the same lifestyle.

Inflation protection strategies:

  • Delay Social Security to maximize your inflation-adjusted benefit
  • Maintain some stock market exposure for growth
  • Consider I-bonds or TIPS for inflation-protected fixed income

The Bottom Line

A successful retirement budget requires honest accounting of income, realistic expense projections, and a plan for healthcare costs. Review your budget annually and adjust as circumstances change.
