Most people saving for retirement have never worked out what they are saving toward.
The Department of Labor puts it plainly in its own guidance: the vast majority of people never take this step, and it is very difficult to save adequately without at least a rough idea of the number.
It is not a difficult calculation. It takes about twenty minutes. And the answer changes how you think about the contribution percentage on your payslip.
This walks through the Department of Labor’s own method, with a worked example.
Start With What You Will Spend
The common rule of thumb: you will need roughly 80 percent of your pre-retirement income to maintain your standard of living.
On a $50,000 salary, that suggests around $40,000 a year in retirement.
The logic is that some costs disappear — commuting, work clothes, and the retirement contributions themselves. Taxes are often lower. But not everything falls, and some things rise.
Where 80 percent is too low: you still have a mortgage or other debt, you face significant medical costs, or you plan an active retirement with travel.
Where it is too high: your home is paid off, you plan a quiet retirement, or you will move somewhere cheaper.
Treat it as a starting point to adjust, not an answer.
Social Security Covers Part of It
This is the part that makes the number less frightening.
According to the Social Security Administration, benefits replace roughly 40 percent of a median wage earner’s income. The proportion varies with your earnings history and the age you claim.
So if you need to replace 80 percent, and Social Security handles about 40, your own savings need to produce the remaining 40 percent.
That is the figure to plan around.
You can get a personalized estimate from the Social Security Administration’s website based on your actual earnings record — considerably better than a rule of thumb, and worth doing before you rely on any calculation.
The Two Things People Underestimate
How long retirement lasts
Current estimates suggest a man retiring at 67 can expect roughly 18 years in retirement, a woman around 20.
Those are averages, which means half of people live longer. And life expectancy has been rising.
The Department of Labor’s guidance is to plan well into your nineties. Running out of money at 88 is a worse error than saving slightly more than you needed.
For couples, plan for the longer life. One spouse is likely to outlive the other, sometimes by many years.
What inflation does over decades
Inflation has averaged around 3 percent annually over the last century, though it varies enormously — 13.5 percent in 1980, 1.6 percent in 1998.
Over a thirty-year retirement, that compounds substantially. The $40,000 that covers your first year will not cover your fifteenth.
Social Security is adjusted for inflation. Your savings are not, unless you plan for it. When estimating, assume a higher rate rather than a lower one — being wrong in that direction is survivable.
The Calculation
Four steps. The example follows someone aged 30, earning $50,000, planning to retire at 65 — so 35 years of saving and, planning conservatively, 30 years of retirement.
The Department of Labor’s worksheet assumes a 7 percent annual return and 3 percent inflation. Reasonable long-run assumptions, not guarantees.
Step 1: Your income goal for year one
Your salary will grow with inflation before you retire, so start there.
Over 35 years at 3 percent inflation, a salary multiplies by roughly 2.81.
$50,000 × 2.81 = $140,695 at retirement
Then take 40 percent — the portion your own savings must cover.
$140,695 × 0.40 = $56,278
That is the income your savings need to produce in your first year of retirement, in the dollars of that year.
Step 2: The total you need saved
Now account for the whole retirement, with your investments still growing and costs still rising.
For a 30-year retirement, the Department of Labor’s factor is about 18.22.
$56,278 × 18.22 = $1,025,408
Roughly a million dollars.
Take a moment with that. Someone earning $50,000 today needs approximately $1 million saved to retire comfortably at 65.
Steps 3 and 4: What you already have, and the gap
Project your existing savings forward to retirement, subtract that from the total, and the remainder is what you still need to accumulate.
The worksheet converts that gap into a target saving rate — the percentage of your current salary to save each year.
That percentage is the actual output. Not the million-dollar figure, which is intimidating and abstract, but a number you can compare against what you are contributing now.
Importantly, the target rate includes your employer’s contributions. If you contribute 4 percent and your employer matches 4 percent, your saving rate is 8 percent — another reason to capture the full match, as covered in which retirement accounts to fill first.
The complete worksheet with all the factors is in the Department of Labor’s free guide, Savings Fitness, available on their website.
On That Million-Dollar Number
Two honest reactions, and both are reasonable.
It is daunting. A million dollars sounds impossible on a $50,000 salary.
It is also less impossible than it looks. That figure is in 2060 dollars, not today’s. And most of it will not come from your contributions — it comes from compounding across 35 years, as we worked through in how much you should save each month.
The relevant question is not whether you can save a million dollars. It is whether you can save the target percentage of your salary, starting now, with an employer match included.
That is a considerably more manageable question.
If the Number Is Out of Reach
For plenty of people it will be, at least at first. The response is not to abandon the exercise.
Save what you can and raise it later. Starting at 5 percent and increasing with each raise beats waiting until you can afford the target. Directing half of every increase to savings is the mechanism that works, for reasons covered in why a raise never feels like enough.
Working longer changes the arithmetic twice. More years of contributions and compounding, fewer years to fund. Retiring at 67 rather than 65 shifts the number more than most people expect.
Delaying Social Security increases the benefit. Claiming later produces a larger monthly payment for life, which reduces what your savings must cover.
Consider what retirement actually looks like. A lower-cost location, a paid-off home, or part-time work in early retirement all reduce the target substantially.
And increase income. The target is a percentage of salary — a higher salary makes the same percentage produce more. That is the case made in how to ask for more money.
Do It Again
This is an estimate built on assumptions about inflation, returns, salary growth, and lifespan. Every one of them will be wrong to some degree.
That is fine. A rough number you revisit beats no number at all.
Redo it every year or two. Your salary changes, your plans change, and your picture of retirement sharpens as it gets closer. What looked abstract at 30 becomes concrete at 45.
The Bottom Line
Assume you need about 80 percent of pre-retirement income. Social Security covers roughly 40 percent for a median earner, so plan for your savings to provide the other 40.
Plan for a long retirement — into your nineties — and account for inflation across all of it.
Run the calculation, get your target saving rate, and compare it against what you are actually contributing including any employer match.
Then close the gap gradually rather than perfectly. The people who end up comfortable are rarely the ones who calculated most precisely. They are the ones who started.
