Is Working One More Year Worth It? How to Compare Two Retirement Dates

You have a retirement date in mind. You have built up savings. The plan looks plausible.

Then the question arrives:

Would we be better off if I worked just one more year?

Another year of income can improve your finances. But that alone does not settle the decision. You are also giving up a year you could spend traveling, being with family, or doing something you have postponed.

The useful question is: What would another year of work buy us—and is that improvement worth the time?

Start with what you want the extra year to accomplish

“More money” is an easy answer, but it is too vague to guide a retirement decision.

You might want another year of work to:

• Support a higher retirement spending budget.
• Build more room for a weak market.
• Pay off a mortgage before your paycheck stops.
• Cover a major expense without stretching the plan.
• Make it easier to wait before claiming Social Security.

Those goals need different tests. Paying off a mortgage does not establish that your spending plan is affordable. Adding savings may change little if the plan already comfortably supports your needs.

Before comparing retirement dates, finish this sentence:

I would work another year if it allowed us to ______.

That gives you something concrete to test.

What changes when you work another year?

The benefit extends beyond what you save from your paycheck.

If earnings cover your expenses, your portfolio can avoid a year of withdrawals. You may also make additional contributions, including an employer match.

With the same planning end age, that means one fewer year funded by your portfolio. The avoided withdrawal already captures that benefit; do not count it twice.

Investment returns affect the result too. Your balance could rise or fall during that year, so a comparison should not depend on getting a favorable market.

Keep your retirement date separate from your Social Security claiming date. You can stop working and claim benefits later.

Another working year may increase your benefit by replacing a lower earnings year. Claiming age has its own effect. SSA explains both factors.

To understand the value of working longer, first compare two retirement dates using the same Social Security claiming age. Then test whether changing the claiming age improves either plan.

Keep the comparison fair

Use the same investment approach, inflation assumptions, and planning end age. Keep the same spending goals, adjusting costs and income affected by the retirement date.

Include changes to health coverage, commuting costs, taxes, and household earnings. Near age 65, estimate coverage costs before and after Medicare eligibility rather than assuming they stay the same.

Compare balances at a common age. Comparing each plan only on its retirement date can hide the withdrawals made by the person who retired sooner.

A simple example: retire at 64 or 65?

Imagine a hypothetical household with:

• $1.5 million invested.
• One spouse planning to retire at 64.
• A $90,000 portfolio withdrawal budget for the year from 64 to 65, including living costs, health coverage, and estimated taxes.
• Social Security planned to begin at 67.
• If the spouse keeps working, household income covers all expenses and taxes, with $30,000 added to investments, including any employer match.

Compare both choices at the same point: when that spouse reaches 65.

To isolate the effect of working, assume no investment growth or losses, no inflation, and no other changes during the year.

Under these assumptions, working another year leaves the household with $120,000 more at age 65.

Only $30,000 comes from additional saving. The other $90,000 comes from avoiding withdrawals.

This illustrates the balance difference, not whether either plan can fund retirement. Actual results depend on returns, cash-flow timing, taxes, healthcare costs, and spending.

Suppose their rule is: We would work another year if it lets us preserve essential spending after a bad market, with no more than two years of reduced travel.

Project both plans through the same end age, including Social Security from 67 and changing healthcare costs. Test the same downturn and record the spending cuts each plan requires.

If only the later date meets their rule, the $120,000 buys an improvement to weigh against a year of freedom. If both meet it, their goal provides less reason to delay. If neither does, another year alone is not enough.

Compare the plans under pressure

A larger projected balance is useful information. It does not tell you how either retirement would feel during a difficult stretch.

Run both retirement dates through the same unfavorable assumptions:

• A market decline in the same calendar year for both plans.
• Higher living costs than expected.
• A major home repair or medical expense.
• A longer retirement than originally planned.

Keep market returns aligned by calendar year to isolate the retirement-date effect. Separately, test a decline just after each retirement date to explore bad timing.

Record how much spending must fall, for how long, and whether essentials are affected. A larger balance matters when it changes an outcome you care about.

Your existing spending flexibility belongs in this comparison. A household willing to postpone a large discretionary purchase has different options from one whose withdrawal budget mostly covers fixed expenses.

Put the value of your time into the decision

A financial projection can estimate the effect of another working year. It cannot decide what that year is worth to you.

Consider what you would actually do if you retired sooner.

Perhaps you would travel with a spouse while you are both healthy. Perhaps you would help an aging parent, spend more time with grandchildren, or leave a job that has become exhausting.

You might also enjoy your work and prefer a gradual transition. In that case, another year may offer income, structure, and social connection at a relatively small personal cost.

Be specific on both sides:

Working another year would give us ______. Retiring sooner would give us ______.

You do not have to assign a dollar value to every personal priority. You do need to acknowledge what you are exchanging.

Set a stopping rule

“One more year” can become a moving target.

Before deciding to stay, define what would make the additional year enough. That could be paying off a specific debt, reaching a savings target, or making a downside scenario manageable without cutting essential spending.

Set review and retirement dates. Decide what you will reconsider if markets leave you short: spending, the retirement date, or a gradual transition. A missed target should trigger a decision, not an automatic extra year.

If the plan meets your needs but leaving still feels difficult, identify the uncertainty. Healthcare worries need a cost estimate; market worries need a downside comparison. A bigger balance may not answer the underlying question.

Make the comparison with your own numbers

Working another year is worth considering when it produces an improvement you value enough to exchange a year of your time.

Start with two versions of your plan: retire as intended, or retire one year later. Compare spending capacity, downside outcomes, and the adjustments each choice might require.

Pathwyze can help you explore those scenarios with your own savings, spending, and income assumptions.

Start your plan, then identify exactly what the extra year would buy you.
