How Much Does a Couple Need to Retire?

Couples do not need twice what a single person needs, because rent, heat, insurance, and many other bills cost the same whether one person lives there or two. But couples spend more than one person alone on food, travel, and care. The real answer comes from your own math: estimate what you will spend in a year, subtract the government checks you and your partner will each receive, and figure out how big your savings must be to fill the gap.

Let me walk you through it, step by step, with plain numbers.

Why Two People Is Not Twice the Cost

Some expenses almost double when two people live together. Others barely move. That difference is the whole reason a couple's number looks so different from a single person's number.

Expense	What happens for a couple
Rent or mortgage, property tax	Usually about the same
Heat, power, internet	Usually about the same
Food, toiletries, laundry	Goes up noticeably, but not double
Cars, gas, car insurance	Often one more vehicle or more driving
Dental care, glasses, prescriptions	Roughly doubles, one set each
Trips, hobbies, gifts	Grows with each extra person

For example, suppose a single person needs $45,000 a year to live on. A couple might need $60,000 to $75,000, not $90,000. The exact figure depends on the life you picture, so it pays to sketch your version out. Our guide to how much you need to retire builds that estimate line by line, and it works the same way for one person or two.

Start With Shared Yearly Spending

Sit down together and guess what a year of retired life looks like. Some couples list it by category. Others just copy today's budget and adjust. Either way works.

Here is an example we will carry through the rest of this post.

Example: Sam and Priya, both 58, think they will spend:

• Housing and utilities: $2,200 a month
• Food and household items: $900 a month
• Cars, gas, insurance: $700 a month
• Health costs not covered elsewhere: $500 a month
• Travel, fun, gifts: $700 a month

Total: $5,000 a month, or $60,000 a year.

Round numbers are fine here. A rough guess you actually make beats a precise number you never get around to.

Count Both Government Checks

Next, look at what each of you will get from government plans. In the United States, that is Social Security. You can start taking it as early as age 62, and your full retirement age, the age where you get your complete amount, is 67 for anyone born in 1960 or later. In Canada, it is the CPP (Canada Pension Plan, based on your working years) plus OAS (Old Age Security, which starts at 65 and grows if you delay it to 70).

Two important points for couples:

• Each partner earns their own check. Social Security and CPP benefits are based on each person's own work record, not on the marriage. Some spouses qualify for extra amounts based on a partner's record, but everyone's own check comes first.
• Waiting usually raises the check. Claiming Social Security before your full retirement age shrinks it permanently. Delaying OAS in Canada to age 70 raises it.

These amounts change every year, and they depend on your earnings history, so check them yourself. The US Social Security Administration posts current details at ssa.gov, and Service Canada does the same at canada.ca. Choosing when to claim is its own decision. We have a plain guide to when to take CPP and OAS if one of you has Canadian credits.

Back to Sam and Priya. For example, imagine their combined checks come to $38,400 a year ($3,200 a month) once both have reached full retirement age.

Fill the Gap With Savings

Subtract the checks from the spending. Whatever is left has to come out of your savings every year.

$$60,000 − $38,400 = $21,600$$

Now, how big a pile lets you pull $21,600 a year without running dry? A common starting point is the 4 percent rule. It suggests you can take out about 4 percent of your savings in the first year, then raise that amount a little each year for rising prices. Outcomes vary with the market and with how long you live, so treat it as a starting estimate, not a promise.

The quick shortcut: multiply your yearly gap by 25.

$$21,600 × 25 = $540,000$$

Check it the other way: 4 percent of $540,000 is indeed $21,600. Here is the whole example in one table.

Step	Amount
Spending, monthly	$5,000
Spending, yearly	$60,000
Combined government checks (example)	$38,400
Yearly gap to fill from savings	$21,600
Savings needed at a 4 percent withdrawal rate ($21,600 × 25)	$540,000

Notice the order of things. The savings number is the result of the plan, not the start of it. Cut $10,000 from yearly spending and the gap falls to $11,600, which needs only about $290,000. One changed assumption moves everything, which is why guessing a savings number without doing the spending part leads people astray. Our 4 percent rule guide explains where that math holds up and where it gets shaky.

What Moves a Couple's Number Around

Same couple, very different totals. These are the levers:

• Retirement age. Retiring earlier means more years to pay for and smaller checks, since claiming Social Security before full retirement age lowers it for good.
• Pensions. A defined benefit pension, a workplace plan that pays a set amount monthly, fills part of the gap on its own.
• Debt. A paid-off house lowers the spending side; a mortgage payment keeps it high.
• Taxes. Part of every withdrawal may go to income tax, and a couple's filing situation differs from a single person's. We break this down in plain terms in how taxes work in retirement.
• Health care before Medicare. Medicare starts at 65. If you retire sooner, you pay for coverage yourself until then.
• The bridge years. Benefits start later than paychecks stop. Savings often carry the load alone from 60ish to 67ish.

No two couples weigh these the same way, so the honest answer really is "it depends," followed by numbers you trust.

Work It Out Together, Today

Guessing "somewhere around a million dollars" is stressful because nobody knows if it is too much or too little. Doing the four steps above turns that fog into one clear number. If you would rather skip the spreadsheet work, When Can I Retire runs the same calculation for you: enter your situation (or upload statements), and it shows the age you can retire, how ready you are today, and every step of the math, including Social Security or CPP and OAS, pensions, taxes, inflation, and the bridge years between stopping work and benefits starting. The first check is free at /signup.

One last thing worth saying plainly. Many couples find their gap is smaller than they feared, especially with two checks arriving. Knowing your number early gives you years to adjust gently, not months to panic. Whenever you start, starting today is the step that matters.
