How much you need to save for retirement is one of the most consequential numbers in personal finance, and it is also one of the most misunderstood. There is no single magic figure. The right amount depends on your income, your expected spending, your health, your time horizon, and how much of your retirement income will come from Social Security. What follows is a practical framework for estimating your target, checking your progress, and adjusting course at any age.
Start With Your Replacement Rate, Not a Random Number
Financial planners commonly suggest that retirees need roughly 70% to 80% of their pre-retirement income to maintain their standard of living. That range comes from the fact that some expenses fall in retirement — commuting costs, work clothing, and retirement contributions — while others rise, notably health care.
A higher earner may need less than 70% because Social Security replaces a smaller share of a large income, while a lower earner may need more because Social Security replaces a larger share. Use the replacement rate as a starting point, then refine it with your actual budget.
Multiply your current gross income by your chosen rate. If you earn $90,000 and target 75%, you would aim for about $67,500 of annual retirement income in today's dollars.
Subtract What Social Security Will Provide
Social Security is the foundation of most American retirement plans. According to the Social Security Administration, the program replaced about 40% of pre-retirement earnings for a typical medium earner, though the exact percentage varies by income level. You can get a personalized estimate by creating a my Social Security account at ssa.gov and reviewing your benefit statement.
Suppose your projected benefit at full retirement age is $2,400 per month, or $28,800 per year. Subtract that from your $67,500 target, and you need about $38,700 per year from your own savings.
One important lever: claiming age. Benefits rise about 8% per year for each year you delay past full retirement age up to age 70, so waiting can meaningfully reduce the portfolio you need to build.
Turn the Income Gap Into a Savings Target
To convert an annual income need into a lump sum, use a withdrawal rate. The widely cited 4% rule suggests you can withdraw 4% of a diversified portfolio in the first year and adjust for inflation thereafter, though many planners now use 3.5% to 4.5% depending on market conditions and longevity.
Divide your income gap by your chosen rate. At 4%, $38,700 divided by 0.04 equals roughly $967,500. That is your target nest egg in today's dollars.
This is an estimate, not a guarantee. It ignores taxes, investment fees, and the sequence of returns, so treat it as a planning anchor rather than a precise finish line.
Benchmarks by Age
Fidelity Investments publishes widely referenced savings benchmarks as multiples of salary. They are a useful gut check, not a rule:
- Age 30: 1x your salary
- Age 40: 3x your salary
- Age 50: 6x your salary
- Age 60: 8x your salary
- Age 67: 10x your salary
If you are behind, do not panic. The most powerful variable is your savings rate, not your starting point. Saving 15% of gross income, including any employer match, is a common target for a worker starting in their 20s. If you start later, you may need to save 20% or more.
Where to Put the Money
Use tax-advantaged accounts first, in this general order:
- 401(k) or 403(b) up to the employer match. An employer match is an immediate return on your contribution. In 2025, employees can contribute up to $23,500, with a $7,500 catch-up for those 50 and older.
- Health savings account (HSA), if you have a high-deductible health plan. HSAs offer a triple tax advantage and can be used for medical costs in retirement.
- Roth or traditional IRA. The 2025 contribution limit is $7,000, with a $1,000 catch-up at 50 and older.
- Back to the 401(k) for additional contributions, then a taxable brokerage account.
Diversify across stocks and bonds, keep costs low, and revisit your allocation as you approach retirement. A target-date fund can automate much of this.
Adjust as Life Changes
Revisit your plan annually or after major events — a raise, a job change, a marriage, a child, or a health diagnosis. Small, consistent increases in your savings rate compound dramatically. Increasing your contribution by 1% of salary each year is a low-pain way to close a gap.
Also consider working a few years longer. Each additional year of work adds savings, shortens the retirement you must fund, and may increase your Social Security benefit — a triple benefit that often outweighs aggressive investment bets.
What to Remember
There is no universal retirement number, but there is a reliable process. Estimate your replacement rate, subtract Social Security, divide the gap by a sustainable withdrawal rate, and compare the result to age-based benchmarks. Then automate contributions to tax-advantaged accounts and review the plan yearly. The earlier you start, the less you need to save each month — and the more flexibility you will have later.
