How Much Do You Need to Retire? Calculate Your Retirement Number

5 minute read

See how much you may need to retire. PensionBee's RetireBy calculator builds a retirement number from where you plan to live and what you have already saved.

Key Takeaways

  • A retirement number built on generalizations can miss by a meaningful margin once you factor in your location and accounts.
  • PensionBee's RetireBy Calculator builds a number tailored by your inputs by weighing your projected cost of living against your projected retirement income.
  • Projected expenses draw on regional cost-of-living data from the Bureau of Economic Analysis, covering housing, food, education, and medical costs.
  • Projected income combines your expected Social Security benefit from SSA data with the 401(k), brokerage, savings, and other income figures you enter yourself.
  • The output is a target number along with a clear read on whether your current savings pace is on track or off track.

‍

Americans say they need $1.46 million to retire comfortably in 2026, according to a recent survey. That’s a $200,000 jump from last year.

That number is an average of what people think they need. It is not built around your life. It is an average, not your answer.

PensionBee's RetireBy Calculator works differently. It combines what you know about your own finances, like your accounts, your location, and your goals, with government data, including BEA cost-of-living figures and SSA benefit estimates. The result is an estimate that's actually yours. That means:

  • A retirement estimate based on where you want to live, the lifestyle you want, and what you’ve already saved. 
  • A number you can refine any time your life changes, so it stays useful instead of stale.

‍

An off-track result isn't a verdict. It's a starting point that gives you a rough sense of how much more you'd need to save, invest, or adjust your timeline to close the gap. That's far more useful than a vague feeling that you should probably be saving more.

The 23% Problem

For a lot of savers, the problem isn't that they're not saving enough. It's that their retirement savings are scattered across multiple accounts and workplace plans. 

23% of Americans with retirement accounts still have multiple balances sitting in old or current workplace plans. That makes it hard to even total up a starting balance, let alone project it forward. If you've changed jobs a few times and left old 401(k)s behind, your real starting point is probably higher than whatever number is in your head right now.

What Goes Into Your RetireBy Estimate

We auto-populate some of the numbers behind your estimate using government data. What you provide is what turns a generic projection into one built around your actual finances:

  • Retirement accounts. Active and old 401(k) balances to help you see your full retirement picture.
  • Investment accounts. Any brokerage or IRA accounts you hold outside an employer plan.
  • Savings accounts. Your current savings balance and other funds you may use in retirement.
  • Other income sources. Rental property or similar income, factored into your overall estimate.

‍

You don't need exact figures. Round numbers and current balances are enough to get a useful estimate started. You can update them any time your accounts change.

How Your Number Actually Gets Built

Two outside data sources help shape your estimate: one for the cost of living where you want to live and one for your estimated Social Security benefits you're entitled to.

Cost of living where you want to retire

This pulls Bureau of Economic Analysis (BEA) data on housing, food, education, and medical costs to estimate the cost of living in different locations. Rent is often the biggest factor in how those costs vary from one state to another. Choosing a different location can therefore change how much you may need to save for retirement, so comparing your estimate across locations can help you see how much that cost difference could affect your number. 

Your expected Social Security benefit

This is modeled from Social Security Administration (SSA) data, based on your own earnings history rather than a generic figure. The SSA calculates your benefit from your highest 35 years of earnings and the age you start collecting. Social Security is one leg of retirement's classic three-legged stool, alongside employer plans and personal savings. On its own, it usually isn't enough to fully fund retirement. Seeing how much weight that leg is actually carrying shows you where the rest of your funding needs to come from.

Keep Your Number Accurate as Life Changes

Your “retirement number” isn’t fixed. Income, account balances, and cost-of-living data all change over time, so revisiting your number regularly, or any time you get a raise, change jobs, or consider relocating, can help keep it current.

The RetireBy Calculator estimates your number by combining real cost-of-living and Social Security data with the accounts you already have. If some of those accounts are still with old employers, rolling your old 401(k)s and IRAs into one PensionBee IRA can help you get a clearer picture of your total savings.

Many rollovers happen automatically once you start the process, and for the ones that need extra attention, our personal rollover managers, called BeeKeepers, are there to help.

Frequently Asked Questions (FAQs)

What is a “retirement number”?

A “retirement number” is an estimate of how much you may need to support the retirement you want. RetireBy creates this estimate using factors like where you plan to live, your lifestyle, current savings, and income sources such as Social Security. 

How do I calculate my personal retirement number?

The RetireBy calculator brings those factors together to estimate your number. Enter details about your location, lifestyle, savings, and expected income to see how your current financial picture compares with what you may need in retirement. 

Does Social Security count toward my “retirement number”?

Yes. Social Security is one leg of the three-legged stool of retirement income, alongside your 401(k) or other employer plan and your personal savings. RetireBy factors in your expected Social Security benefit when estimating your number, it estimates what you'll actually need to save to cover the gap.

How much does where I live affect how much I need to retire?

Where you live can meaningfully affect your retirement number, since housing prices, healthcare expenses, property taxes, food and utility costs, and state tax policies all vary widely by location. RetireBy factors in your planned location when estimating your number, adjusting your projected expenses to reflect the cost of living where you intend to retire.

What if I have old 401(k)s from previous jobs?

Old 401(k)s still count toward your retirement number, but only if you can find and total them accurately. Rolling them into one account can help make it easier to get a complete, up-to-date balance whenever you recalculate.

How often should I recalculate my “retirement number”?

Checking in regularly is a reasonable baseline, plus any time your income, account balances, or retirement location plans change.

What counts as "other income" in a “retirement number” calculation?

Other income generally refers to income sources beyond your account balances and Social Security. For example, rental income.
