How Much Do I Need to Retire? The Complete 2026 Guide

The question "how much do I need to retire?" gets asked millions of times every year and answered with oversimplified rules of thumb that may or may not apply to your situation. The honest answer is: it depends. But the calculation is not as complicated as financial services companies make it seem - and knowing your actual number is one of the most motivating things you can do for your financial journey. Let's work through it.

The 4% Rule: A Starting Point, Not a Guarantee

The 4% rule, derived from the landmark Trinity Study, suggests that a retiree can withdraw 4% of their portfolio in year one and adjust for inflation annually, with a high probability of the portfolio lasting 30 years. This gives us a simple formula: your retirement number = annual expenses × 25. If you expect to spend $60,000 per year in retirement, you need $1,500,000.

Important caveats: the 4% rule was based on historical U.S. market returns and a specific bond/stock allocation. In a lower-return environment, some researchers now recommend a 3%–3.5% withdrawal rate for more conservative planning. If you're retiring early (before 60), your portfolio needs to last 40–50 years, which argues for an even more conservative withdrawal rate. And if you have significant guaranteed income (Social Security, pension), your portfolio needs to cover only the gap.

Factor in Social Security

Social Security is a significant asset that most retirement calculators undervalue. The average Social Security benefit in 2026 is approximately $1,900/month ($22,800/year). The maximum benefit for someone who earned at or above the wage base throughout their career and claims at age 70 is over $4,800/month. You can get your personalized benefit estimate by creating an account at SSA.gov and reviewing your Social Security Statement.

Claiming strategy matters enormously. Claiming at 62 (the earliest option) permanently reduces your benefit by 25%–30% compared to claiming at your Full Retirement Age (FRA). Delaying to age 70 increases your benefit by 8% per year beyond FRA. For most healthy retirees, delaying to 70 is the single highest-return "investment" available.

Build Your Personal Retirement Projection

Here's a step-by-step framework:

1. Estimate annual retirement expenses: Start with your current spending and adjust for expected changes - no mortgage if it'll be paid off, lower transportation costs, higher healthcare costs, more travel in early retirement.
2. Subtract guaranteed income: Social Security + any pension. The remainder is what your portfolio must cover.
3. Apply the 4% rule (or 3.5% for early retirees): Divide the portfolio-dependent amount by 0.04 to get your target number.
4. Adjust for inflation: If you're 25 years from retirement, the purchasing power of today's dollars will be significantly lower. Assume roughly 2.5%–3% annual inflation and use a future-value calculator to see what your current retirement number target needs to grow to.
5. Calculate your savings rate needed: Use a compound interest calculator to determine how much you need to save monthly to reach your target by your target retirement date.

Healthcare: The Biggest Wildcard

Healthcare is the most underestimated retirement expense. Fidelity's most recent estimate suggests an average retired couple will need approximately $315,000 in savings specifically to cover healthcare costs in retirement - and that's with Medicare coverage beginning at 65. If you retire before 65, you'll need to bridge the gap with marketplace insurance (potentially $1,500–$2,500/month in premiums for a couple in their early 60s). Long-term care - which Medicare largely doesn't cover - represents another major potential expense. A long-term care insurance policy purchased in your 50s is far cheaper than one purchased in your 60s, and worth serious consideration.

The Gap Between "Can Retire" and "Want to Retire"

Many people who can technically retire by the numbers choose not to - because their identity, social connections, or sense of purpose is deeply tied to their work. Others discover their actual retirement spending is higher than projected because they're suddenly traveling, pursuing hobbies, and enjoying the time freedom they worked for. Building a financial model is essential, but so is spending time thinking about what retirement will actually look like for you - and whether the number you're targeting actually supports that vision.
