Put last month's bills beside an estimate of what would come in after your last paycheck. If you were born between 1965 and 1980, that simple exercise may tell you more about retirement than a headline about Gen X. Start with rent or a mortgage, groceries, health care and anyone who relies on your income. Then see how much your expected income would cover.
Put a survey number in context
Two households with the same pay can have very different retirement costs. One may own a home outright while the other still pays rent. A survey can tell you what people think they'll need. For a savings target that fits your household, start with the bills you'll have to pay and the income you expect to have.
What the $40,000 figure measured
A 2023 National Institute on Retirement Security report used Census survey data for 2020 and found median Gen X household retirement savings of $40,000. The median is the middle of the distribution. Keep both the date and the household measure in view when reading that figure. A current account statement answers a different question.
Give the worry a name
A survey about retirement worries captures how people felt when they answered. If the worry sounds familiar, give it a name. Are you concerned about keeping up with rent, finding health coverage or helping a parent? Getting specific tells you which bill, benefit estimate or family conversation to start with.
Choose a range of dates
Write down a few years when leaving work might be realistic. For each end of that range, sketch the bills you expect to have, including housing, insurance, food and any debt payments. Put a question mark beside expenses you can only guess at. You can return to those lines when you have better figures.
Keep emergency cash separate
Money set aside for a broken furnace or a gap between jobs already has a job. List emergency reserves separately when you add up the savings you expect to spend in retirement. That keeps the same dollars from showing up twice and gives you a clearer idea of what is available for an unexpected bill today.
Work out the monthly gap
Suppose you expect to spend $3,800 a month and have $2,900 in regular income after taxes. That leaves $900 a month, or $10,800 a year, to cover from other resources. Those numbers are an example. Use your own after-tax figures so the gap reflects what you would actually have available to spend.
Count caregiving on both sides
Helping a parent or another relative can mean paying for groceries, driving to appointments or cutting back paid hours. Put those costs and any change in pay on separate lines. If other family members have agreed to help, write down what they will cover. Keep any help that is still uncertain out of your starting estimate.
Check for a pension
Some employers still offer defined-benefit pensions. The plan generally uses a formula, often based on pay and years of service. Ask for an estimate for the dates you're considering, including any pension from a previous job. The plan can tell you how the start date and payment choice affect the amount and any survivor benefit.
Read your 401(k) balance
Your 401(k) balance reflects contributions, investment gains or losses, fees and any withdrawals. Look at the latest statement, then check what a projection assumes about future deposits and returns. If your pay or work schedule changes, those assumptions may need updating before you use the projection in a retirement budget.
Find your match and vesting terms
If your employer offers a match, the plan documents say what you need to contribute to receive it. They also explain vesting, which determines how much of the employer money you keep if you leave. Your own contributions are fully vested. Check both rules if you're considering a job change or an earlier last day.
Track down old accounts
A few job changes can leave retirement money in several places. Make a list of each account's provider, type, current balance and fees. Add any pension statements, too. You can do this while leaving the money where it is. The list shows what you already have and which records still need a closer look.
Know your Social Security ages
The Social Security Administration lists a full retirement age of 67 for people born in 1960 or later. Eligible workers can claim their own retirement benefits as early as 62. Put your last expected paycheck and possible benefit start dates on the same calendar. They may fall months or years apart.
Compare monthly benefits
If your full retirement age is 67, claiming your own retirement benefit at 62 generally pays about 70% of the full monthly amount. After full retirement age, delayed credits add 8% per year of delay and stop accruing at 70. Compare those monthly amounts with your health, income and household expenses before deciding when to claim.
Check the 2026 contribution limits
In 2026, the IRS sets the standard 401(k) employee contribution limit at $24,500. If the plan permits catch-ups, eligible workers age 50 or older can generally add up to $8,000. Workers turning 60, 61, 62 or 63 in 2026 have a higher $11,250 catch-up limit instead. Ask your plan administrator whether the Roth catch-up rules apply to you.
Allow for gaps in earnings
A projection may assume you keep earning and contributing at the same pace. A layoff, an illness or a switch to part-time work can change that quickly. Look at the assumptions in your current estimate and try one version with a break in pay. That shows what a few uneven years could mean for your own budget.
Use the bills you actually pay
Pull recent housing, grocery, utility and insurance bills to get a starting figure for your household. Then ask which lines would change after you leave work. Commuting may cost less. Even if the mortgage is paid off, property taxes, insurance and repairs still need a place in the budget.
Put Medicare on the calendar
Medicare eligibility generally begins at 65, on a separate schedule from Social Security retirement benefits. If you expect job-based coverage to end before then, check what interim coverage would cost. If you keep working past 65, ask how your employer plan coordinates with Medicare and confirm your enrollment window so you can plan for a change in coverage.
Look back at irregular expenses
A car repair, dental work or an annual insurance bill can get lost in a budget built from one month's spending. Look through a full year of statements and write down the larger expenses that arrived only once or twice. Use those figures to estimate a monthly amount for the less predictable bills.
Try an earlier exit date
Run the budget for continuing to work and for leaving earlier than planned. Health, family needs and layoffs can change the decision. If the earlier date leaves a much bigger gap, look at which expenses or income estimates account for the difference. Then you know what the backup plan needs to cover.
Review investment risk and fees
A shortfall can make a fast-return pitch sound tempting. Before changing your investments, check what you already own, how much it costs and what a loss would mean for the rest of your plan. Ask the provider to explain a fee or investment you can't identify on the statement.
Give savings time to grow
Starting earlier gives savings more time to grow and gives a household more years to contribute. The amount still depends on what goes in and how investments perform. If you're starting later, use the time and income you have now to build an estimate. Keep any assumed investment gains visible in the calculation.
Write out two versions
Write out one budget for your preferred retirement date and another for an earlier exit. Use the same assumptions about prices, then note which income or spending figures would actually change in each version. Compare the monthly gaps. If a pension start date or a health premium drives the difference, that is the figure to verify first.
Start with one page
Bring together a recent month of bills, your latest retirement account statements and a Social Security estimate. On one page, put expected monthly spending on the left and recurring income on the right. Leave a blank beside anything you still need to check. You can update that page as the numbers get clearer.
