Retirement Health Cost Calculator - Estimate Your Lifetime Medical Expenses
Healthcare is the most underestimated expense in retirement planning. Fidelity's 2024 estimate: $315,000 lifetime healthcare cost for a 65-year-old couple. The formula: Lifetime Health Cost = Annual Cost x (1+medical inflation)^years, summed over the retirement horizon.
The Formula Explained
Healthcare Cost in Year t = Base Annual Cost x (1 + Medical Inflation Rate)^t. Base annual cost at age 65 (single): Medicare Part B $2,220 + Part D $600 + Medigap Plan G $1,680 + Dental $1,200 + Vision $450 + Hearing $350 + OOP $2,800 = approximately $9,300/year.
At 5.5 percent medical inflation: Age 70: $12,155. Age 75: $15,885. Age 85: $27,135. Age 90: $35,464. Present value of 25-year total (at 6 percent discount rate): approximately $285,000.
| Age | Annual Cost (single) | Annual Cost (couple) | Key Cost Drivers |
|---|---|---|---|
| 65-69 | $9,300 | $18,600 | Medicare enrollment, Medigap, prescriptions |
| 75-79 | $15,885 | $31,770 | Chronic disease management begins |
| 85-89 | $27,135 | $54,270 | LTC needs begin, dental and hearing escalate |

3 Real-World Examples
Example 1: Barbara, 64, Planning Medicare Enrollment
Baseline: $8,280/year. Lifetime PV at 5.5 percent inflation through age 90: approximately $258,000. She designates $258,000 of her $780,000 portfolio as a dedicated healthcare reserve - 33 percent of her portfolio.
Example 2: Richard and Marilyn, Comparing Medicare Plans
Traditional Medicare plus Plan G: $5,100/year in known premiums with minimal OOP. Medicare Advantage: zero premium but $7,000 annual OOP maximum. Over 25 years with 4 bad health years: $285,000 PV vs $265,000 for Advantage. $20,000 difference favors Advantage, but Plan G's predictability wins for Richard.
Example 3: George, 70, Adding Long-Term Care to His Plan
Baseline PV: $215,000 (20 years). Adding 40 percent probability of 3-year home health care: +$46,600. Plus 15 percent probability nursing facility: +$50,000. Total healthcare reserve need: $305,000-$325,000. He purchases a hybrid life insurance policy with LTC benefits.
Common Mistakes to Avoid
- Using general CPI inflation to project healthcare costs.
- Excluding dental, vision, and hearing from healthcare cost estimates.
- Not accounting for Medicare Part B and D premium increases over time.
- Forgetting the IRMAA Medicare surcharges for higher-income retirees.
- Treating long-term care as a separate problem rather than a healthcare cost.
- Assuming Medicare Advantage plan availability and network stability over 25 years.
- Not building a dedicated healthcare reserve fund.
