How Much Do I Need to Retire? Your Complete Savings Guide

Most Americans don't know their retirement number. According to the Employee Benefit Research Institute, more than 40% of workers have never calculated how much they need to save for retirement. That uncertainty is expensive - because without a target, every dollar you save (or don't save) is arbitrary.

This guide gives you a clear number, a proven method to calculate it, and a step-by-step walkthrough of the Retirement Savings Calculator so you can see exactly where you stand today.

Two Methods to Find Your Retirement Number

Method 1: The 25x Rule (Simple and Powerful)

The most popular rule in retirement planning: multiply your expected annual retirement spending by 25. This is based on the 4% safe withdrawal rate - the idea that you can withdraw 4% of your portfolio each year without running out of money over a 30-year retirement.

Example:

• Annual retirement spending: $60,000
• Retirement target: $60,000 × 25 = $1,500,000

The 25x rule is a useful starting point, but it doesn't account for Social Security benefits or pension income. If you'll receive $1,500/month from Social Security, that's $18,000/year - reducing your portfolio need by $450,000 (18,000 × 25).

Method 2: The Replacement Rate Method

A more personalized approach: target replacing 70-90% of your pre-retirement income. Most financial planners use 80% as the default, since retirees typically spend less on commuting, work clothing, and payroll taxes - but more on healthcare.

If you earn $90,000/year, your replacement rate target is $72,000/year (80%). Subtract estimated Social Security and pension income, then apply the 25x rule to the remainder.

How to Use the Retirement Savings Calculator

The Retirement Savings Calculator does this math for you - including growth projections, inflation adjustment, and a gap analysis showing whether your current savings rate is enough.

Step 1: Enter your current age and planned retirement age. The longer your runway, the less you need to save each month. Starting at 30 vs. 45 makes a massive difference thanks to compound growth.

Step 2: Enter your current retirement savings balance. Include all retirement accounts: 401(k), IRA, Roth IRA, 403(b), and any pension. Don't include taxable brokerage accounts unless they're designated for retirement.

Step 3: Enter your monthly contribution. Include your personal contributions plus any employer match. If your employer matches 3% and you contribute 6% of a $80,000 salary, your combined monthly contribution is about $600. See how the math works out in our 401(k) Calculator.

Step 4: Set your expected annual return. The default of 6-7% (real, inflation-adjusted) is historically reasonable for a diversified stock-heavy portfolio. Conservative investors might use 5%; aggressive investors might model 8%. Don't assume past returns guarantee future performance.

Step 5: Review the gap analysis. The calculator shows your projected balance at retirement vs. your target. A positive gap means you're on track. A negative gap tells you exactly how much you need to adjust - either by saving more, retiring later, or planning to spend less.

Retirement Savings Benchmarks by Age

Fidelity's guidelines offer a practical age-based check:

If you earn $70,000 at age 40, the target is $210,000 in retirement savings. Behind this benchmark doesn't mean you've failed - it means you need to adjust your contribution rate now rather than later.

What to Do If You're Behind

Increase contributions immediately. Even a 1% increase in your savings rate today compounds significantly over decades. Many 401(k) plans allow automatic annual increases - set it and forget it.

Capture the full employer match. If you're not contributing enough to get your employer's full match, you're leaving guaranteed returns on the table. This is the highest-ROI move in personal finance.

Consider delaying retirement. Working two extra years does three things at once: more contributions go in, your portfolio has more time to grow, and you draw on it for fewer years. Our Retirement Withdrawal Calculator models how long your savings will last at different withdrawal rates.

Factor in Social Security strategically. Claiming at 62 vs. 70 changes your benefit by up to 77%. Read our Social Security Benefits Guide to understand how timing affects your lifetime payout - then subtract that expected income from your portfolio target.

Compare Roth vs. Traditional contributions. If you expect to be in a higher tax bracket in retirement, shifting to Roth contributions now locks in today's lower rate. Our Roth vs. Traditional IRA Calculator shows the after-tax difference side by side.

Key Factors That Affect Your Retirement Number

• Life expectancy: Plan for age 90 to avoid outliving your money
• Healthcare costs: Average retirement healthcare spending exceeds $300,000 for a couple
• Inflation: A 3% inflation rate halves your purchasing power in 24 years (Rule of 72)
• Sequence of returns risk: A market downturn in early retirement hurts far more than one mid-career
• Social Security timing: Each year you delay claiming (up to 70) increases your benefit by ~8%

Frequently Asked Questions

How much should I have saved for retirement by age?

Fidelity's benchmark: 1× salary by 30, 3× by 40, 6× by 50, 8× by 60, and 10× by the time you retire around 67. These are guidelines, not hard rules - your target depends on your expected spending in retirement.

What is the 25x rule for retirement?

The 25x rule says your retirement portfolio should be 25 times your expected annual spending. It's derived from the 4% safe withdrawal rate - the historically supported rate at which retirees can draw down a diversified portfolio for 30+ years without running out of money.

What rate of return should I assume for retirement planning?

For a diversified portfolio (stocks + bonds), a 6-7% real (inflation-adjusted) return is commonly used for long-term planning. Conservative portfolios (heavy bonds) might use 4-5%. Don't plan around the S&P 500's historical ~10% - that's nominal, not inflation-adjusted, and your portfolio will likely hold some bonds.

How does Social Security reduce my savings target?

Social Security replaces a portion of your pre-retirement income - typically 30-50% for middle-income earners. Multiply your expected annual Social Security benefit by 25 and subtract that from your portfolio target. If you'll receive $20,000/year, you need $500,000 less in savings.

What if I start saving for retirement late?

The math gets harder but not impossible. Starting at 45 instead of 25 means you need to save roughly 3-4× more per month to reach the same target. Focus on maximizing contributions (the 2026 401(k) limit is $23,500; catch-up contributions for 50+ are an additional $7,500), reducing planned retirement spending, and considering working a few extra years. See our 401(k) Contribution Guide for specific strategies.
