Healthcare Cost CAGR Calculator: Annualized Health Spending Growth
Work out the annualized growth rate of healthcare costs between two years — the figure that exposes how much faster medical spending grows than general inflation, and how aggressively to plan for it in retirement.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Annual healthcare cost growth | Total cost growth |
|---|---|---|
| $5k to $8k over 10yr | 4.81% | 60.00% |
| $3k to $6k over 8yr | 9.05% | 100.00% |
| $10k to $20k over 15yr | 4.73% | 100.00% |
| $2k to $2.5k over 5yr | 4.56% | 25.00% |
How This Calculator Works
Enter the starting and ending annual healthcare cost and the years between them. The calculator finds the compound annual growth rate that connects the two figures. Use the same scope on both sides (premiums only, or total spend including out-of-pocket) for a meaningful trend.
The Formula
Compound Annual Growth Rate
Start is the beginning value, End is the ending value, n is the number of years
Worked Example
Healthcare costs rising from $5,000 to $8,000 over 10 years is a 4.8% annual growth rate — total growth 60%. That's well above general inflation (typically 2% to 3% annual), which is why projecting current health spending forward at general inflation systematically understates the true cost in retirement.
Key Insight
Healthcare cost inflation has historically outpaced general inflation by 2 to 4 percentage points annually in the US. Projecting current spending at general inflation systematically underprojects future healthcare costs — Fidelity's widely cited retirement healthcare estimate (around $315,000 per couple in 2024) reflects this gap. Building a retirement plan against general-inflation healthcare projections is the most common medical-cost planning error.
Why healthcare inflation runs above general CPI
U.S. healthcare CPI 2014-2024 (BLS). ~40% cumulative increase. ~3.5% CAGR. General CPI ~32% cumulative, ~2.8% CAGR. Substantial 0.7% spread.
Premium employer coverage (KFF Employer Survey). Family coverage 2014: $16,834. 2024: $25,572. ~52% increase, ~4.3% CAGR. Substantially outpacing wages.
Drivers. (1) AGING POPULATION. Boomers substantially aging into Medicare. Substantial cost.
(2) NEW TECHNOLOGIES. GLP-1 drugs (Ozempic, Wegovy) $10K+/year. Gene therapies $1M+/treatment. Substantial mix shift.
(3) ADMINISTRATIVE COSTS. U.S. ~30% healthcare spending administrative (vs ~15% other OECD). Substantial overhead.
(4) PRESCRIPTION DRUGS. Substantial price increases brand drugs. IRA 2022 Medicare negotiation phase-in.
(5) HOSPITAL CONSOLIDATION. Substantial market power, higher negotiated rates.
(6) WAGES. Healthcare labor substantial shortage post-pandemic. Substantial wage increases.
Strategic implications for individuals. Plan substantial cost growth. If $25K family premium 2024, project $35-40K 2034 base rate. Substantial retirement planning factor.
Out-of-pocket cost trends and HSA strategy
OUT-OF-POCKET MAXIMUMS (ACA). 2024 individual $9,450, family $18,900. Substantial increase from 2014 limits ($6,350, $12,700). ~50% growth ~4% CAGR.
DEDUCTIBLES. Employer plan avg 2024 (KFF): $1,787 individual. 2014: $1,217. ~47% growth.
HIGH-DEDUCTIBLE HEALTH PLANS. Substantial adoption 2014-2024. Now ~30% employer enrollees. HSA-eligible.
HSA. 2024 limits $4,150 individual, $8,300 family + $1,000 age 55+ catchup. Triple-tax-advantaged. (1) Deductible contributions. (2) Tax-free growth. (3) Tax-free qualified medical withdrawals.
Strategy. (1) HSA SUBSTANTIAL retirement vehicle. After age 65 withdrawals for any purpose taxed as IRA. Medical withdrawals always tax-free.
(2) MAX FUND HSA. Don't spend currently. Pay current expenses out-of-pocket, invest HSA for 30-40 years compounding.
(3) DOCUMENT MEDICAL EXPENSES. Reimburse decades later tax-free.
(4) MEDICARE TIMING. Cannot contribute HSA after Medicare enrollment age 65. Plan accordingly.
(5) HEALTHCARE COSTS RETIREMENT. Fidelity 2024 estimate: $165K per person 65+ lifetime. Substantial.
U.S. healthcare cost CAGR benchmarks 2014-2024
Reference CAGRs for healthcare components.
| Component | 10-year CAGR |
|---|---|
| Medical care services CPI | 3.5-4% |
| Hospital services | 4-5% |
| Physician services | 2.5-3% |
| Prescription drugs | 2.5-3% |
| Employer family premium | 4-5% |
| Out-of-pocket max (ACA) | ~4% |
| General U.S. CPI | ~2.8% |
| Medicare per beneficiary | 3-4% |
Substantial outpacing of CPI reflects aging population, new technologies (GLP-1s, gene therapies), administrative complexity, labor shortages. Retirement healthcare ~$165K/person lifetime (Fidelity 2024).
Frequently Asked Questions
How is healthcare cost CAGR calculated?
Same formula as any compound annual growth rate. (ending / starting) ^ (1/years) − 1. From $5,000 to $8,000 over 10 years works out to about 4.8% per year.
How fast do US healthcare costs grow?
Long-run averages: 4% to 7% per year for total US healthcare spending, well above general inflation (2% to 3%). Premiums often grow faster than out-of-pocket; deductibles have grown fastest in recent years as plans shift more cost to consumers.
What scope should I use?
Total annual healthcare spend (premiums + out-of-pocket including deductibles, copays, and uncovered care) gives the truest picture. Premiums only often understates because out-of-pocket has grown faster than premiums in the deductible-shifting era.
Does this apply to Medicare?
Medicare premiums and out-of-pocket costs also grow faster than general inflation. Plan retirement healthcare against healthcare-cost growth, not general inflation. Fidelity, Schwab, and similar retirement calculators use a healthcare-specific inflation rate.
Can I lower the growth rate?
Mostly no on the macro level. At the personal level: switching plans annually, using HSAs aggressively (triple tax advantage), reviewing prescription costs annually, and choosing high-deductible plans paired with HSAs can reduce the growth rate of your specific spend.
When is this calculator unreliable?
Less reliable when insurance plan changed (different deductibles/copays), when HSA/FSA flows masked, when drug formularies/generics substituted, or when negotiated rates differ across payers. For retirement healthcare planning use $165K/person lifetime baseline (Fidelity 2024) and project from there.

Methodology & Review
Healthcare cost CAGR = (ending/beginning)^(1/years) − 1. Calculator returns compounded annual growth rate. U.S. healthcare CPI 2014-2024 ~3-4% nominal CAGR. Medical care services slightly higher than goods. National Health Expenditure ~17% of GDP 2023 (CMS). RELIABILITY: Reliable for documented prices same scope (same procedure, same provider/insurer, comparable network). Less reliable when (a) insurance plan changed (different deductibles, copays); (b) HSA/FSA flows masked; (c) drug formularies/generics substituted; (d) negotiated rates differ across payers.
