Find out exactly how much you'll have at retirement, whether you're on track, and how much you need to save each month to hit your goal. Includes inflation adjustment and savings benchmarks.
The most widely used rule of thumb is the 25x Rule — also known as the retirement number formula. Multiply your desired annual retirement income by 25 to get your target retirement savings:
The 25x Rule comes from the 4% Safe Withdrawal Rate, a guideline derived from extensive research (the "Trinity Study") showing that withdrawing 4% of a diversified portfolio annually has historically lasted 30+ years in nearly all market scenarios.
Fidelity Investments publishes widely-referenced retirement savings benchmarks based on your salary. These are targets to keep you on pace for a comfortable retirement at age 67:
So if you earn $70,000/year and are 40 years old, you should have approximately $210,000 saved for retirement.
The 401(k) is the cornerstone of most American retirement plans. In 2026, the contribution limit is $23,500 ($31,000 if age 50+). Crucially, most employers offer a matching contribution — typically 3–6% of salary. This is free money and should always be maximized before any other investment.
Individual Retirement Accounts allow up to $7,000/year ($8,000 if 50+) in tax-deductible contributions (income limits apply). Taxes are paid on withdrawal in retirement, ideally when you're in a lower tax bracket.
Same contribution limits as Traditional IRA, but contributions are made after-tax and all withdrawals in retirement are tax-free. This is particularly powerful for younger people who expect to be in a higher tax bracket later. Roth is generally the better choice if you're early in your career.
1. 401(k) up to employer match (free money) → 2. Pay off high-interest debt → 3. Max out Roth IRA → 4. Max out remaining 401(k) → 5. Taxable investment accounts.
Two people both want to retire at 65 with $1.5 million, assuming 7% annual returns:
Every decade of delay roughly triples the monthly savings required. There is no financial decision more impactful than starting early.
