Short answer

Most people earning $100k will not spend that much in retirement. Plan for closer to $70k of yearly spending, subtract steady income, then multiply the gap by 25.

If you earn $100,000 a year, you may have heard you should save 10 or even 12 times your salary before you retire. That sounds huge. The good news is you probably do not need that much.

Here is the short answer. People who earn $100k usually spend less than that after they stop working. A reasonable planning number for many of them is $70,000 to $75,000 a year of spending. Then you subtract money that arrives automatically, like Social Security in the US or CPP and OAS in Canada. Whatever gap is left, multiply by 25 to get the size of the pot you need. This is called the 4% rule, and it says you can take out about 4% of your savings the first year and adjust for inflation after that. Our 4% rule guide walks through why that math holds up.

Let's build your number step by step.

Step 1: Guess your yearly spending in retirement

Your paycheck includes some things that will shrink or vanish when you stop working:

That is why most people can live well on roughly 70% of their old take-home spending. On a $100k salary, many households find $70,000 a year covers it comfortably.

But the honest way to do this is simpler: look at what you actually spend today. Check your bank statements from the last few months. Add up rent or mortgage, food, insurance, travel, fun. Some costs go down (commuting, payroll taxes). One big cost can change depending on your age: health care. If you retire before 65 in the US, you will need to cover your own coverage until Medicare starts. You can read about coverage ages on medicare.gov.

For this article we will use $72,000 a year as our example spending number.

Step 2: Subtract the money that shows up on its own

This is the step people forget, and it saves you hundreds of thousands of dollars.

Social Security payments depend on your earnings history and the age you claim them. You can see your own estimate by logging in at ssa.gov. Most people can claim as early as 62. Your full retirement age is 67 if you were born in 1960 or later. Waiting from 67 to 70 makes each payment 24% bigger, because the benefit grows a little each month you wait.

In Canada, CPP can start as early as 60, though starting early means smaller monthly payments for life. OAS payments can be delayed up to age 70 for a larger amount. Your estimates live on canada.ca.

The exact amount varies a lot from person to person, so treat these figures as made-up placeholders:

For example: Suppose your combined household benefit is $28,000 a year starting at age 67. That might come from one higher earner's record or two people's records added together. Check your own estimate, because yours could be very different.

Our guide on when to take Social Security shows how much the claiming age changes your lifetime total.

Step 3: Turn the gap into a pot of savings

Now do three pieces of subtraction and multiplication.

Find the gap.

$72,000 spending − $28,000 benefits = $44,000 a year your savings must produce.

Multiply the gap by 25.

Under the 4% rule, the money you need is 25 times the gap:

$44,000 × 25 = $1,100,000

So in this example, a household earning $100k needs about $1.1 million invested plus a $28,000 annual benefit to support $72,000 of yearly spending from age 67 onward.

Notice something important. Ten to twelve times a $100k salary would be $1,000,000 to $1,200,000 on top of everything else in the simple version of that rule of thumb. Using spending and benefits instead gets you to the same neighborhood, but now you know exactly where each dollar goes, which makes the target feel less magical.

Three spending levels, side by side

Your answer moves with your lifestyle, not your salary. Here is the same math at three spending levels, all assuming the same $28,000 example benefit:

Yearly spending Benefit (example) Savings must cover Needed pot (gap × 25)
$65,000 $28,000 $37,000 $925,000
$72,000 $28,000 $44,000 $1,100,000
$80,000 $28,000 $52,000 $1,300,000

Spending $7,000 more per year in retirement takes $175,000 more in savings. Spending $7,000 less frees up that much. Every dollar of yearly difference equals $25 of pot, either way.

If your paid-off home means your retirement housing cost drops sharply, you might land closer to the first row than you think.

What if you want to retire earlier than 67?

Two things change when you retire before your full retirement age.

First, your benefits shrink. Claiming Social Security at 62 instead of your full retirement age cuts each monthly payment by about 30%. In our example, $28,000 at 67 becomes roughly $20,000 at 62. Second, there are years with no benefits at all. If you retire at 60 and claim at 62, you bridge two years entirely from savings.

The bridge years matter. They push your required pot higher, even though the long-run gap looks similar. We go deeper into this in retire early if benefits start later, and our piece on retiring at 62 works the whole thing out for that exact age.

Do not forget taxes

One more honest correction to the picture above: some of that spending comes to you pre-tax. Traditional retirement accounts, like a 401(k) in the US or an RRSP in Canada, are saved before income tax. Withdrawals from them get taxed as regular income later. So if part of your $72,000 must flow through taxed withdrawals, you technically need slightly more pulled out to end up with the same spendable cash. The reverse is true for Roth-type accounts, which come out tax free.

The direction and size of that adjustment depend on your mix of account types and the rules where you live. Our plain-language walkthrough of how taxes work in retirement shows the difference without needing a calculator.

If you got started late

Plenty of people earning six figures reach their 50s with far less than $1.1 million. It happens more often than you would guess. Job changes, kids, medical bills, and simply not knowing the rules eat decades of savings for lots of people. None of that makes you bad with money.

What actually helps is knowing two things precisely: your gap, and how close you are today. Once you know both, the choices become concrete instead of scary. Work longer by a couple years, trim planned spending, delay benefits to make them bigger, or catch up during high-earning years. Each knob has a real, calculable effect.

That is the whole job here. When Can I Retire works out the age you can actually retire and how ready you are today, showing every step of the math including your Social Security or CPP and OAS, any pension, taxes, inflation, and the benefit-free years before checks start. The check is free, and you can type your numbers or upload a statement. You can start at /signup.

The reason precision beats panic: a vague $1.5 million goal feels impossible. A precise gap of $44,000 a year, crossed off by a known benefit and a growing pot, feels like a plan.

Key points to remember

Common questions

Does my spouse's salary double the number I need?

Not really, because you share costs. Two people do not spend twice what one person spends on housing, utilities, or groceries. Combined household spending goes in the math once, and both people's benefits count toward covering it. Often two people retiring together need much less than two separate singles.

Should my house count toward my retirement savings?

It counts only if you plan to turn it into cash, either by selling or borrowing against it. If you plan to stay put, the house mainly helps by lowering your future housing bill. A lower housing cost means a smaller yearly spending number, which trims $25 from your pot for every $1 of yearly savings.

What about long-term care costs near the end of life?

Big medical or care expenses late in life are a real wildcard, and they vary enormously. Some people never face large ones. Many retirees keep a cushion beyond the base math, or hold back one investment account untouched as a backup layer. How much cushion fits you depends on your health, family history, and comfort level with uncertainty.

Is 25 times my gap safe if the market crashes early?

The 4% rule was built to survive rough sequences of bad years, and history backs it across many market patterns. Early retirement stretches the money over more years, so some early retirees prefer taking out closer to 3.5%, which means multiplying the gap by about 29 instead of 25. That tradeoff between safety and a bigger pot is worth thinking through honestly.
