Retirement Budget Planning: How to Make Your Money Last in Retirement
A practical guide to building a retirement budget -- the 4% rule, essential vs. discretionary spending, healthcare cost planning, and strategies to stretch your retirement savings.
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.
