Retirement Savings Calculator

What Your Retirement Nest Egg Really Is

A retirement nest egg is the total pool of savings and investments you will draw on once you stop working. The calculator above projects that pool by simulating your account year by year: it starts with what you have saved today, adds your annual contributions and any employer match, and lets the whole balance grow at an expected rate of return until the retirement age you choose. The result is a single, concrete number you can plan around.[10]

Why project at all? Because retirement is the largest financial goal most households will ever fund, and small decisions made decades early have outsized consequences. The U.S. Department of Labor notes that fewer than half of Americans have calculated how much they need to save for retirement. A projection turns a vague worry into an actionable target—and shows you, in dollars, how much a higher contribution rate or a few more working years can change the outcome.[11, 28]

How This Calculator Projects Your Nest Egg

Under the hood, the calculator runs a year-by-year simulation rather than a single closed-form formula. It begins with your current balance, then for each year it adds your contributions and any employer match, applies your expected rate of return, and carries the growing balance forward until you reach your target retirement age. Contributions are treated as invested at the start of each period, so they begin compounding immediately—the same annuity-due approach the SEC's Investor.gov compound interest calculator uses. The chart and the final balance update the moment you change any input.[14, 10]

Two assumptions deserve a closer look. First, the model applies a single, constant rate of return every year; real markets deliver that average only as a long-run trend, with sharp gains and losses along the way. Second, the projection is a pre-tax, pre-fee estimate of your invested accounts alone—it does not subtract income tax on future withdrawals, account or fund fees, or layer in Social Security. Treat the number as a disciplined estimate rather than a guarantee, and pressure-test it by running a conservative and an optimistic return side by side.[15, 16]

How Much Do You Actually Need to Save?

A widely cited rule of thumb is to save roughly 15% of your gross income each year for retirement, including any employer match. The exact figure depends on when you start, how long you expect to work, and how much of your current income you want to replace—planners often target replacing 70% to 85% of pre-retirement income once Social Security is factored in. The calculator lets you test your own contribution rate against your salary and see whether the resulting nest egg lands where you need it.[10, 17]

Be honest about the inputs. Use your real gross salary, the percentage you actually contribute (not what you wish you contributed), and a return assumption grounded in history rather than hope. Broadly diversified stock portfolios have returned roughly 7% per year after inflation over the very long run, but future returns are never guaranteed, and a portfolio shifts toward bonds as you near retirement, which lowers the expected return. When in doubt, run the calculator twice—once with an optimistic return and once with a conservative one—and plan around the gap.[15, 16]

Employer Match: The Closest Thing to Free Money

Many employers contribute to your 401(k) based on what you put in—a common formula is a 50% or 100% match on the first 6% of salary you contribute. If you earn $70,000 and your employer matches 50% up to 6%, contributing 6% ($4,200) earns you an extra $2,100 a year you would otherwise leave on the table. Failing to contribute enough to capture the full match is, quite literally, declining part of your compensation. The calculator models this with separate match-rate and match-limit inputs so you can see the employer dollars stacked on top of your own.[1, 11]

One caveat: employer contributions are often subject to a vesting schedule, meaning you must stay employed for a set number of years before the matched money is fully yours. Your own contributions are always 100% vested immediately. Check your plan documents so you understand what you would forfeit by leaving early—and weigh that against a job change.[1]

401(k), IRA, and Roth: Where to Hold Your Savings

The nest egg the calculator projects can live in several tax-advantaged accounts. A workplace 401(k) lets employees defer a generous amount each year—for 2026 the IRS raised the employee deferral limit to $24,500, up from $23,500—and it is the only account that comes with an employer match. An Individual Retirement Arrangement (IRA) carries a separate, lower limit of $7,500 for 2026 but offers a far wider menu of investments. Most savers can fund both in the same year, which is how they stack tax-advantaged space.[2, 3, 18]

The bigger choice is traditional versus Roth. Traditional 401(k) and IRA contributions are typically pre-tax: you get a deduction now and pay ordinary income tax when you withdraw in retirement. Roth contributions are made with after-tax dollars, but qualified withdrawals—including all the growth—come out completely tax-free. Younger savers in a low bracket often favor Roth; high earners expecting a lower retirement bracket may prefer traditional. The calculator projects the pre-tax balance; remember that a traditional account is worth less after the eventual tax bite, while a Roth balance is yours to keep.[5, 6]

Roth IRAs add one more wrinkle: the ability to contribute phases out at higher incomes. For 2026 that range runs from $153,000 to $168,000 of modified adjusted gross income for single filers and from $242,000 to $252,000 for married couples filing jointly—above the top, a direct Roth IRA contribution is off the table. Traditional IRA deductions phase out as well once you or a spouse are covered by a workplace plan. A Roth 401(k) at work, by contrast, has no income limit, which is why higher earners often lean on it for tax-free growth.[5, 18]

Saving for Retirement When You Are Self-Employed

No employer plan does not mean no tax-advantaged saving. Freelancers, contractors, and small-business owners have their own toolkit. A SEP-IRA is the simplest: for 2026 you can contribute up to 25% of net self-employment earnings, capped at $72,000. A Solo 401(k)—a one-participant 401(k) for an owner with no employees—lets you contribute both as the "employee" (up to the $24,500 deferral limit, or $32,500 with the age-50 catch-up) and as the "employer," often allowing a larger total. A SIMPLE IRA suits very small payrolls with a lower limit and mandatory employer contributions.[23, 24, 25]

These accounts compound exactly the way the calculator models, so you can plug a self-employed contribution into the annual savings field and project just as a salaried worker would. The trade-off is that you shoulder both halves of the contribution yourself, with no employer match to lean on—one more reason to automate deposits and revisit the amount each year as your income changes. Publication 560 walks through the contribution math, which is slightly more involved for the self-employed because the deductible contribution itself reduces the earnings the limit is based on.[23]

The Power of Compounding Over a Career

The single most powerful lever in retirement saving is not how much you invest—it is how long you let it compound. Money invested in your twenties has 40 years to grow, and because returns earn returns, the final decades do the heaviest lifting. A 25-year-old who saves $300 a month at a 7% return reaches roughly $720,000 by age 65. A saver who waits until 35 to start the same $300 monthly habit ends with about $340,000—less than half—despite contributing only ten fewer years.[14, 15]

This is why financial educators urge people to start contributing as early as possible, even at a modest rate, and to raise that rate over time—many plans let you schedule automatic annual increases. Watch how the growth bar in the chart above starts almost flat and then bends sharply upward in your final working decade. That steepening curve is compounding doing its work, and it is the reason a percentage point of return or a few extra years of saving moves the final number so dramatically.[17]

Inflation and Your Real Nest Egg

A $2 million nest egg sounds enormous today, but if it is 35 years away, inflation will erode much of its purchasing power. Consumer prices—the cost of living the Bureau of Labor Statistics tracks through the Consumer Price Index—have historically risen around 3% a year on average, enough to roughly double prices every 24 years. The groceries, rent, and health care your future dollars must cover will cost far more than they do now. Toggle the inflation setting in the calculator to see your projected balance restated in today's dollars—the "real" value—which is the figure that actually tells you how comfortably you could live.[17, 26]

Inflation is also why holding too much cash for too long is risky for long-horizon savers. Money parked in a low-yield account can lose real value year after year, while a diversified portfolio that includes stocks has historically outpaced inflation over multi-decade periods. The trade-off is volatility along the way—something you smooth out by keeping a long time horizon and not selling during downturns.[15, 16]

Behind on Savings? Catch-Up Contributions After 50

If you started late or paused saving to raise a family, the tax code gives you a way to accelerate. Once you reach age 50, the IRS allows additional "catch-up" contributions above the standard limit—for 2026 that is an extra $8,000 in a 401(k), which lifts your own deferral to $32,500, plus an extra $1,100 in an IRA. Under the SECURE 2.0 Act, savers aged 60 to 63 get an even larger "super" catch-up of $11,250, pushing the 401(k) employee total to $35,750. These higher limits let older workers shovel more into tax-advantaged accounts during their peak earning years.[4, 18]

Catching up is not only about contribution limits. Raising your savings rate by even a few percentage points, working two or three extra years, and delaying Social Security all meaningfully increase the income you can draw later. Use the calculator to test a later retirement age—the combination of more contributions and more compounding years is often more powerful than people expect.[13]

The 2026 Roth Catch-Up Rule for Higher Earners

A SECURE 2.0 provision finally takes effect in 2026, and it reshapes how higher earners make catch-up contributions. If your wages from the employer sponsoring your plan exceeded $150,000 in the prior year, any catch-up you make must now be a Roth (after-tax) contribution rather than a traditional pre-tax one. The IRS confirmed the $150,000 figure—indexed up from the law's original $145,000—in Notice 2025-67, and the threshold is based on the FICA (Social Security) wages reported in Box 3 of your W-2.[19, 20]

In practice this changes the tax timing, not your ability to save: you lose the upfront deduction on the catch-up portion, but that money and its growth later come out tax-free. Two caveats matter. If your plan does not offer a Roth option, affected workers may not be able to make catch-up contributions at all until the plan adds one, so it is worth confirming with your administrator. And because the rule keys off prior-year wages from that specific employer, changing jobs mid-career can change whether it applies. The Treasury and IRS issued final regulations in September 2025, with a short good-faith transition period as plans update their systems.[19]

The Saver's Credit: A Bonus for Lower- and Middle-Income Savers

Beyond the tax deferral every retirement account offers, lower- and middle-income savers can claim an extra reward: the Saver's Credit, formally the Retirement Savings Contributions Credit. It returns 10%, 20%, or 50% of up to $2,000 in contributions ($4,000 for couples) directly off your tax bill. For 2026 the credit phases out above $40,250 of adjusted gross income for single filers, $60,375 for heads of household, and $80,500 for married couples filing jointly. You claim it on Form 8880.[21, 18]

A few rules narrow who benefits. The credit is non-refundable, so it can erase a tax bill but will not generate a refund on its own, and full-time students and anyone claimed as a dependent are not eligible. Even so, for a worker in the right income band it is one of the highest-return moves in the tax code—effectively a second match stacked on top of any employer contribution. If your income qualifies, contributing even a few hundred dollars to an IRA or 401(k) can unlock it.[21]

Common Retirement Saving Mistakes to Avoid

The most expensive mistake is cashing out a 401(k) when changing jobs. Beyond the income tax due, the IRS generally imposes a 10% additional tax on early withdrawals taken before age 59½, and you permanently lose all the future compounding that money would have produced. Rolling the balance into a new employer plan or an IRA keeps it invested and tax-deferred—and a direct, trustee-to-trustee rollover sidesteps the mandatory withholding and 60-day deadline that trip up indirect transfers. A close second is failing to contribute enough to capture the full employer match—leaving guaranteed money behind every single paycheck.[7, 1, 22]

Other frequent missteps include letting lifestyle creep absorb every raise instead of bumping your contribution rate, holding a portfolio too conservatively in your thirties (sacrificing decades of growth out of fear), and ignoring fees—an extra one percentage point in annual expenses can quietly consume a large share of your lifetime returns. Reviewing your plan once a year and increasing your savings rate alongside raises keeps small leaks from sinking the projection.[15]

From Saving to Spending: Withdrawals and RMDs

Building the nest egg is only half the job; the other half is turning it into income that lasts. A long-standing planning benchmark suggests withdrawing around 4% of the balance in the first year of retirement and adjusting for inflation thereafter, though the right rate depends on your time horizon, portfolio, and flexibility. Social Security will cover part of your spending—the maximum benefit for someone retiring at full retirement age is $4,152 a month in 2026, after benefits rose 2.8% with that year's cost-of-living adjustment. You can estimate your own benefit at the SSA website; claiming at 62 permanently reduces it, while delaying past full retirement age (67 for anyone born in 1960 or later) adds roughly 8% for each year you wait, up to age 70, where the benefit tops out at 124% of the full amount.[12, 13, 27]

Tax-deferred accounts eventually come with required minimum distributions (RMDs). Under current law you must begin taking RMDs from traditional 401(k)s and IRAs at age 73, an age that rises to 75 in 2033 under SECURE 2.0. Roth IRAs are not subject to RMDs during the original owner's lifetime, and as of 2024 neither are Roth 401(k)s. Miss one and the penalty is steep—a 25% excise tax on the shortfall, though that drops to 10% if you correct it within two years. The IRS publishes the distribution tables, so it pays to plan withdrawals before they become mandatory.[8, 9]

Frequently Asked Questions

Key Takeaways

Projecting your retirement nest egg turns an abstract goal into a concrete number you can act on. Start early to harness decades of compounding, contribute at least enough to capture your full employer match, aim for a savings rate around 15% of income, and revisit your plan as your salary grows—for 2026 the limits reach $24,500 in a 401(k) and $7,500 in an IRA, with catch-ups for those 50 and older. Adjust for inflation to understand your real purchasing power, use catch-up contributions if you are behind, and remember that working a few extra years is one of the most powerful levers available. The calculator above lets you test each of these decisions—change one input at a time and watch how the nest egg responds.[10, 18]
