Retirement Calculator

Retirement savings is money you set aside during your working years to fund your lifestyle once you stop earning a paycheck. Unlike emergency savings — which you might need to tap in 3 to 12 months — retirement savings is designed to last 20 to 40 years after you stop working. That long time horizon changes everything about how the money should be invested: in your 20s and 30s you can take more risk because you have time to recover from market downturns; in your 50s and 60s the mix gradually shifts toward bonds and cash to protect what you have built. Most retirement savings lives inside tax-advantaged accounts like 401(k)s, IRAs, or local equivalents, which means part of your 'return' comes from upfront tax deductions or tax-free growth rather than purely from market gains. Understanding the rules of these accounts — contribution limits, employer matches, withdrawal ages, required minimum distributions — is just as important as picking the right investments, because a single misstep can cost tens of thousands of dollars in unnecessary taxes or penalties. The social and psychological dimensions matter too: retirees who plan ahead report higher life satisfaction than those who don't, because financial anxiety is one of the strongest predictors of poor sleep, strained relationships, and delayed medical care. Treat retirement savings as a long-term project with three phases — accumulation (ages 20–50), pre-retirement transition (ages 50–65), and decumulation (ages 65+) — and revisit your plan at each phase boundary. The most common failure mode is treating retirement savings as an afterthought until your late 40s, then trying to 'catch up' with aggressive contributions that are unsustainable. The second-most-common failure mode is the opposite: aggressively saving 25% of income in your 20s and 30s, then burning out and cutting back to 5% in your 40s right when compound growth would have done the most work. A steady 10–15% contribution rate sustained across a full career outperforms boom-and-bust saving almost every time. Successful retirement savers treat the contribution as a non-negotiable monthly bill, just like rent or a car payment — once it is automated, willpower stops being part of the equation.

The most widely cited benchmark for retirement income is the 4% rule: you can withdraw 4% of your portfolio in year one of retirement, then adjust that dollar amount for inflation each year, and your portfolio has historically lasted at least 30 years in nearly every market scenario tested. Work backwards from your expected annual spending: if you want $50,000 per year in retirement, you need a portfolio of roughly $1.25 million ($50,000 / 0.04). For $80,000 per year you need about $2 million. Most financial planners suggest replacing 70% to 85% of your pre-retirement income, since commuting, work clothes, and payroll taxes disappear — though healthcare and travel often rise. The 4% rule is conservative; many retirees spend less in their 70s and 80s than in their 60s, so 4.5% or even 5% can be sustainable in many cases. The single biggest variable is your time horizon: retiring at 60 versus 65 changes the math dramatically because the portfolio has to last longer. Use the calculator above to model your own situation. For a more conservative plan, some planners use a 3.5% initial withdrawal rate, which provides extra cushion against sequence-of-returns risk — the danger that a market downturn hits just as you start withdrawing. Geographic arbitrage also helps: many retirees maintain a lower cost of living by relocating to states with no income tax (Florida, Tennessee, Texas) or to lower-cost-of-living countries. Healthcare is the wild card: a 65-year-old couple today has a 50% chance that one of them will live past 90, and long-term care costs in the US average $70,000 to $100,000 per year for a nursing home. Plan for it explicitly rather than assuming Medicare or basic insurance will cover it. Inflation is the silent killer of long-term retirement plans. At 3% annual inflation, the purchasing power of a dollar halves roughly every 24 years, which means a portfolio designed to last 30 years needs to grow about 1.8x in nominal terms just to maintain its real value. The 4% rule already accounts for this by adjusting withdrawals upward each year, but it assumes inflation stays near the long-term US average of 3%. If you face a decade of 5% inflation, your required initial withdrawal rate drops to about 3.2% to maintain the same standard of living. The only robust hedge against inflation is a portfolio that includes equities and real assets like TIPS (Treasury Inflation-Protected Securities) or REITs, which historically pass through inflation better than nominal bonds or cash.

Annual withdrawal = Portfolio × 4%

Retirement accounts come in two flavors: tax-deferred (you get a tax break now, pay taxes later) and tax-free (you pay taxes now, withdraw tax-free later). In the United States, the four most common accounts cover most workers. A 401(k) is employer-sponsored, allows contributions up to $23,000 in 2024 (with a $7,500 catch-up if you are 50+), and often includes an employer match — typically 50 cents to a dollar on the first 6% of salary. The Traditional IRA is opened individually and lets you deduct contributions from current income, but withdrawals are taxed as ordinary income. The Roth IRA is funded with after-tax dollars but grows tax-free and is withdrawn tax-free in retirement, which is ideal if you expect to be in a higher tax bracket later in life. The SEP IRA and SIMPLE IRA are designed for self-employed people and small businesses. Outside the US, equivalents include the UK SIPP, Canadian RRSP/TFSA, Australian Super, and Japanese iDeCo. Choose based on your tax bracket now versus expected in retirement, and always capture the full employer match first — it is an instant 50% to 100% return on your contribution. The Roth versus Traditional choice deserves more nuance than most guides provide. If you are in the 22% federal bracket today and expect to be in the 12% bracket in retirement (a common trajectory after you stop working), Traditional wins. If you expect to be in a higher bracket in retirement (rare but possible if you plan to live on a large taxable portfolio), Roth wins. For most middle-income workers, a 50/50 split across both account types hedges against future tax uncertainty. Self-employed individuals have additional options: a Solo 401(k) lets you contribute up to $69,000 per year in 2024 (combined employee + employer portions), and a SEP IRA is simpler to administer with the same high limits. The order of operations matters: always contribute enough to your employer plan to capture the full match first (it is an instant 50–100% return), then max out a Roth IRA ($7,000 in 2024, or $8,000 if 50+), then return to your 401(k) for any additional savings.

There are common benchmarks for how much you should have saved at each age, derived from studies by Fidelity, T. Rowe Price, and the Stanford Center on Longevity. The multiples below assume you retire at 65 with about 10x your final salary. If your household income is $100,000, aim for $30,000 by age 25, $100,000 by 35, $250,000 by 45, $500,000 by 55, and $1,000,000 by 65. These are rough targets, not hard rules — workers who start saving later can compensate by saving a higher percentage of income — but they provide a useful gut-check. The benchmarks assume a consistent contribution rate of 10% to 15% of gross income and a portfolio mix that gradually becomes more conservative with age. If you are behind, the most powerful lever is usually increasing your savings rate by 1% to 2% per year, not chasing higher investment returns. These benchmarks also assume you have access to employer-sponsored retirement plans and reasonable investment options. Lower-income workers who qualify for the Saver's Credit can get a federal tax credit worth up to $1,000 per year for retirement contributions — a substantial boost that many eligible households fail to claim. The benchmarks also assume 'full retirement age' around 65, which is no longer realistic for many workers: a 2024 Gallup poll found that the average expected retirement age in the US is now 66, and one in five workers expect to retire after 70 due to insufficient savings. Starting at 25 versus 35 typically doubles your final nest egg at the same contribution rate, because the early money has time to compound through two more market cycles. The same logic applies to mid-career catch-up efforts: workers who start at 40 and save 20% of income can still reach a comfortable retirement, but the comfort requires a much higher savings rate than workers who started at 25. The biggest risk to the milestone approach is treating it as binary — either you hit 1x by 30 or you have 'failed'. In reality, every additional dollar saved at any age compounds for the rest of your life, so a worker who starts at 35 with $0 saved can still build a $1 million portfolio by 65 with a disciplined 18% savings rate. Use the milestones as motivational reference points, not pass-fail tests. The most common psychological trap is what researchers call 'future discounting' — undervaluing future benefits relative to present consumption. Counter it by framing retirement savings as paying your future self first, not as deprivation. The behavioral research is unambiguous: workers who treat retirement saving as a non-negotiable line item, like rent, accumulate 3–4x more wealth than workers who treat it as discretionary.

Targets assume a household income of $100,000 and consistent saving of 10–15% of income. Your actual targets scale with your income.

Consider Maria, a 35-year-old software engineer earning $110,000 per year. She has $45,000 in her 401(k) today, contributes 10% of her salary ($11,000 per year), and her employer matches 4% ($4,400). Her portfolio is currently 80% stocks and 20% bonds, with an expected long-term return of 6% per year. If she continues at this pace until age 65, her portfolio will grow to roughly $1.42 million — exceeding the $1.1 million benchmark for her income. The composition at retirement will look something like: $980,000 from her contributions ($45,000 today + $369,000 over 30 years) and $440,000 from investment growth. Applying the 4% rule, she can sustainably withdraw about $57,000 per year, more than her current take-home pay. If she bumps her contribution to 15% instead, the same model produces roughly $1.85 million — an extra $430,000 from a single decision to save 5% more of her salary. This is why retirement planning responds so dramatically to small changes in contribution rate. Now stress-test the same scenario: what if her investments return only 4% per year instead of 6%? Her final balance drops to about $1.05 million — still above the $1.1 million benchmark for her income if she raises her contribution rate by 1% in response. What if she takes a 3-year career break at age 40 to care for a parent? Her portfolio drops by about $80,000 in contributions and forgone growth, ending at roughly $1.34 million — still functional, but with less margin. What if a market crash hits in her first year of retirement, dropping her portfolio 30% just as she begins withdrawals? This is sequence-of-returns risk: withdrawing from a depleted portfolio prevents recovery. Maria's mitigation strategy is to hold 2 years of expenses in cash or short-term bonds at the moment of retirement, so she does not have to sell stocks at the bottom. Always run multiple scenarios, not just the baseline.

The most expensive retirement planning mistakes fall into three buckets. First, behavioral mistakes: panic-selling during a market crash (like 2008 or 2020) locks in losses and forfeits the recovery. Studies consistently show that the average investor earns about half the return of the funds they invest in, purely because of emotional buy-and-sell decisions timed around news headlines. Second, structural mistakes: not capturing the full employer match (leaving free money on the table), taking a 401(k) loan that comes due when you change jobs, or mixing up Roth and Traditional accounts when you move jobs. About 1 in 4 workers who leave a job cash out their 401(k) rather than rolling it over — an average forfeit of $20,000 in taxes and penalties, plus all future growth on that money. Third, planning mistakes: underestimating healthcare costs in retirement (Medicare does not cover most dental, vision, or long-term care), underestimating life expectancy (a 65-year-old couple today has a 50% chance that one of them lives past 90), and ignoring inflation. A reasonable rule of thumb is to assume healthcare costs of $300,000 to $500,000 per person above age 65, on top of normal living expenses. Other frequent errors include: claiming Social Security at 62 without modeling the lifetime reduction, treating your home equity as a retirement asset without a plan to access it, and assuming your spending will drop dramatically in retirement (it usually drops by only 10–20%, not 50%). A particularly common trap is 'lifestyle inflation' — every time you get a raise, you also raise your cost of living, leaving your savings rate unchanged despite earning more. The fix is mechanical: every time your salary goes up, immediately raise your retirement contribution by 1% to 2% of the increase. Over a 30-year career, that single habit can add 30–50% to your final nest egg without changing your day-to-day spending. Review your plan at least once a year, increase contributions by 1% of salary with every raise, and never voluntarily cash out a 401(k) when changing jobs — roll it over to an IRA instead.

Enter your current age, the age you plan to retire, your current retirement savings, the amount you contribute each year, and your expected annual return on investment (5% to 7% is realistic for a diversified portfolio). The calculator will project your balance at retirement, estimate your sustainable annual withdrawal using the 4% rule, and show how your balance evolves over time. Adjust the inputs to model different scenarios: what if you work 5 more years? What if you save 5% more of your salary? What if your investments return 6% instead of 7% What if inflation runs at 4% instead of 2%? Use the results to identify the single lever that has the biggest impact on your retirement — for most people that lever is contribution rate, not investment selection. The calculator also produces a year-by-year balance chart, which helps you visualize how compounding accelerates in the final 10–15 years before retirement. That hockey-stick shape is the reward for staying the course during the slower accumulation decades. If your projection falls short of the $1 million mark (or 10x your final salary), the calculator can show you exactly how much extra you need to save each month, or how many additional working years are required to close the gap. Most users should run at least three scenarios: a baseline (your current plan), an optimistic (working 3 more years with 7% returns), and a pessimistic (retiring 2 years early with 4% returns and 4% inflation). The gap between optimistic and pessimistic often exceeds $500,000, which is why scenario planning — not single-point forecasting — is the foundation of good retirement planning. Talk the inputs through with a partner or trusted advisor; numbers you have said out loud tend to stick better than numbers you have only read.
