Open the Retirement Savings Calculator →Retiring at 55 is a legitimate goal — but it requires significantly more savings than retiring at 65, because your money needs to last 30–40 years rather than 20–25. Here is what early retirement actually requires.
The 4% rule was designed for a 30-year retirement starting at 65. If you retire at 55, your savings need to last 40 or more years. Research suggests a 3.5% withdrawal rate is more appropriate for a 40-year retirement — meaning you need more capital for the same income.
| Desired Annual Income | Target at 65 (4% rule) | Target at 55 (3.5% rule) |
|---|---|---|
| $40,000/year | $1,000,000 | $1,143,000 |
| $60,000/year | $1,500,000 | $1,714,000 |
| $80,000/year | $2,000,000 | $2,286,000 |
| $100,000/year | $2,500,000 | $2,857,000 |
A critical challenge in early retirement is bridging the gap between when you retire and when you can access retirement accounts:
This means early retirees need a separate “bridge” portfolio in taxable accounts (ISAs, general investment accounts, or ETFs) to cover expenses until retirement accounts become accessible.
In the USA, early retirees face a critical problem: Medicare eligibility begins at 65. From 55 to 65, you need private health insurance. ACA marketplace plans for a 55-year-old typically cost $800–$1,500/month. This alone requires an additional $200,000–$300,000 in savings, or must be factored into your annual spending budget.
In the UK and South Africa, state healthcare (NHS and public hospitals) provides a safety net, but many early retirees budget for private medical cover for quality and speed of access.
The FIRE (Financial Independence, Retire Early) movement has developed practical frameworks for early retirement. Key variants:
Adjust the return rate to 3.5% and set your retirement age to 55 to see exactly what you need saved — and your monthly saving target to get there.
