How Much More Does Retiring Early Really Cost?
Retiring at 62 instead of 67 is not just "five fewer years of saving." Three costs stack on top of each other: a lower safe withdrawal rate because your money has to last longer, a permanently reduced Social Security check, and years of paying full price for health insurance before Medicare starts. This calculator breaks out all three so you can see exactly where the extra cost comes from โ not just one opaque final number.
1. The Withdrawal Rate Drops
The standard 4% rule assumes roughly a 30-year retirement, starting around 65. Retire earlier and your money needs to stretch further, so most planners recommend a lower starting withdrawal rate:
| Retirement Age | Horizon | Suggested Withdrawal Rate |
|---|---|---|
| 55โ59 | ~35โ40 years | 3.25% |
| 60โ64 | ~30โ35 years | 3.5% |
| 65โ69 | ~25โ30 years | 4.0% |
| 70+ | ~20โ25 years | 4.5% |
A lower withdrawal rate means the same annual spending requires a bigger portfolio โ this alone can add hundreds of thousands to your number.
2. Social Security Is Permanently Reduced
Claiming before your Full Retirement Age (67 for anyone born 1960 or later) locks in a smaller check for life:
| Claim Age | % of Full Benefit |
|---|---|
| 62 | 70% |
| 63 | 75% |
| 64 | 80% |
| 65 | 86.67% |
| 66 | 93.33% |
| 67 (FRA) | 100% |
| 70 | 124% |
A smaller guaranteed check means your portfolio has to cover a bigger share of your spending โ which raises your number again.
3. The Medicare Gap
Medicare eligibility starts at 65. Retire earlier and you're responsible for your own health coverage โ COBRA or a marketplace plan โ until then, often $10,000โ$15,000 a year for a couple. This calculator adds that as a separate lump-sum line so it doesn't quietly get lost inside your regular spending number.
