What Is Retirement?

Retirement is the stage of life when you stop working and live off your accumulated savings, investments, and other income sources. For most people, retirement planning is one of the most important financial endeavors they will ever undertake. The goal is to accumulate enough wealth during your working years to support yourself for potentially 20 to 30 years or more without a regular paycheck.

One of the most important factors that affect a person's decision to retire is whether it is even financially possible in the first place. While it is somewhat possible to retire with nothing in savings and to rely solely on Social Security, it is generally a bad idea for most due to the sheer difference between a working income and Social Security benefits. The average Social Security retirement benefit replaces only about 40% of pre-retirement income, while most financial experts recommend aiming for 70% to 80% replacement.

This Retirement Calculator helps you answer four critical questions: How much do you need to retire? How can you save enough? How much can you withdraw after retirement? And how long will your money last? Each tab above addresses one of these questions, giving you a comprehensive retirement planning toolkit. Use the calculators together to build a complete retirement plan tailored to your financial situation.

How Much to Save for Retirement

The amount you need to save for retirement depends on several factors including your current age, desired retirement age, life expectancy, desired retirement lifestyle, expected investment returns, and inflation. The "How Much Do You Need?" calculator tab above provides a personalized estimate based on your specific circumstances. However, several well-known guidelines can help you set benchmarks along the way.

Financial services company Fidelity recommends having a certain multiple of your salary saved at key ages: 1x your salary by age 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67. These benchmarks provide useful checkpoints to see if you are on track. If you are behind, you may need to increase your savings rate, extend your working years, or adjust your retirement expectations. Use the Retirement Calculator above to see where you currently stand and what adjustments might be needed.

Key Retirement Rules of Thumb

The 10% to 15% Savings Rule

Most financial experts recommend saving 10% to 15% of your pre-tax income each year during your working years. If you start saving in your 20s, 10% may be sufficient. If you start later, you may need to save 15% or more to catch up. This rule assumes you will work until full retirement age and maintain a similar standard of living in retirement.

The 70% to 80% Income Replacement Rule

A widely accepted guideline suggests that you will need 70% to 80% of your pre-retirement income to maintain your standard of living after you stop working. Your expenses may decrease because you are no longer saving for retirement or paying payroll taxes, but healthcare and leisure costs often increase.

The 4% Withdrawal Rule

The 4% rule is one of the most famous retirement planning guidelines. It states that you can withdraw 4% of your retirement savings in your first year of retirement, then adjust that dollar amount for inflation each year, and have a high probability of your money lasting 30 years. For example, if you have $1 million saved, you could withdraw $40,000 in your first year. This rule was developed from historical market data and is a useful starting point, but you should adjust based on your specific situation, asset allocation, and market conditions.

These rules work together. If you need $50,000 per year in retirement and follow the 4% rule, you would need $1.25 million saved. The "How Much Do You Need?" calculator tab above factors in your specific numbers for a more precise target.

Retirement Savings Vehicles

Choosing the right accounts for your retirement savings can have a massive impact on your after-tax wealth. Each type of account offers different tax advantages, contribution limits, and rules. Understanding these differences helps you maximize your savings.

401(k) Plans

A 401(k) is an employer-sponsored retirement account that allows you to contribute pre-tax dollars directly from your paycheck. The 2026 contribution limit is $23,500, with an additional $7,500 catch-up contribution allowed for those aged 50 and older. Many employers offer matching contributions, which is essentially free money. Always contribute enough to get the full employer match before considering other retirement accounts. The tax deferral means you pay taxes on withdrawals in retirement, potentially at a lower rate.

Traditional IRA

A Traditional IRA allows you to contribute up to $7,000 per year in 2026 ($8,000 if age 50+), with tax-deductible contributions if your income falls below certain thresholds. Earnings grow tax-deferred, and withdrawals in retirement are taxed as ordinary income. Traditional IRAs offer a wider range of investment options than most 401(k) plans.

Roth IRA

A Roth IRA uses after-tax contributions, meaning you do not get a tax deduction now, but qualified withdrawals in retirement are completely tax-free. This can be extremely valuable if you expect to be in a higher tax bracket in retirement. Contributions can be withdrawn at any time without penalty. Income limits apply for direct contributions, but a backdoor Roth IRA strategy is available for high earners.

Health Savings Account (HSA)

An HSA is often considered the ultimate retirement account because contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. If you have a high-deductible health plan, maxing out your HSA each year and paying medical expenses out of pocket while letting the HSA grow can create a substantial tax-free retirement healthcare fund.

For most people, the optimal ordering is: contribute enough to your 401(k) to get the full employer match, then max out a Roth IRA or Traditional IRA, then return to your 401(k) to maximize contributions. The Investment Calculator can help you project the growth of your retirement accounts over time.

Asset Allocation Strategies

Asset allocation is how you divide your retirement savings among different investment categories like stocks, bonds, and cash. Your allocation is the single most important determinant of your long-term investment returns and the level of risk you take. A well-diversified portfolio helps you capture market growth while managing downside risk.

A common rule of thumb is to subtract your age from 110 or 120 to determine the percentage of your portfolio that should be in stocks. For example, a 30-year-old would hold 80% to 90% stocks, shifting toward bonds as retirement approaches. At age 65, the stock allocation might be 45% to 55%. This gradual shift reduces portfolio volatility as you near retirement, protecting the savings you have accumulated.

Target-date funds are an increasingly popular option that automatically adjusts your asset allocation based on your target retirement year. These funds provide a hands-off approach to asset allocation, rebalancing automatically and becoming more conservative over time. If you prefer a do-it-yourself approach, consider a three-fund portfolio consisting of a total US stock market index fund, a total international stock index fund, and a total bond market index fund. This simple strategy provides broad diversification at very low cost. Use the Retirement Calculator withdrawal tab to test how different return assumptions affect how long your money will last.

Social Security Timing Strategies

When to start collecting Social Security is one of the most important decisions you will make in retirement planning. Your monthly benefit amount depends on your claiming age, and the difference between claiming early versus late can be hundreds of thousands of dollars over your lifetime.

Your full retirement age (FRA) is between 66 and 67, depending on your birth year. Claiming at FRA gives you your full benefit amount. Claiming as early as age 62 permanently reduces your monthly benefit by up to 30%. Delaying benefits past FRA increases your benefit by about 8% per year until age 70, after which there is no further increase. Someone who delays from 62 to 70 can receive more than double the monthly benefit.

The optimal claiming strategy depends on your health, life expectancy, marital status, and other retirement income sources. If you expect to live past average life expectancy, delaying benefits maximizes your lifetime income. If you have health concerns or need the income earlier, claiming sooner may be the right choice. Married couples have additional strategies available, such as spousal benefits and survivor benefits, which can coordinate claiming to maximize total household benefits. Factor your expected Social Security income into the "other income" field of the retirement calculators for accurate projections.

Healthcare Costs in Retirement

Healthcare is one of the largest and most unpredictable expenses in retirement. According to Fidelity, a 65-year-old couple retiring in 2026 can expect to spend approximately $315,000 on healthcare throughout retirement, not including long-term care. This estimate includes Medicare premiums, supplemental insurance (Medigap), Medicare Part D prescription drug coverage, and out-of-pocket costs.

Medicare covers a significant portion of healthcare costs but does not cover everything. Original Medicare (Parts A and B) covers hospital stays and doctor visits but has deductibles, copayments, and does not cover dental, vision, hearing aids, or long-term care. Many retirees purchase Medigap supplemental insurance and Medicare Part D prescription drug coverage to fill these gaps. Medicare Advantage plans (Part C) offer an all-in-one alternative but have restricted provider networks.

Long-term care is a particularly important consideration. About 70% of people aged 65 or older will need some form of long-term care services in their lifetime. The cost of a nursing home can exceed $100,000 per year. Long-term care insurance can help cover these costs, but premiums are expensive and increase with age. Planning for healthcare costs is essential for a comprehensive retirement strategy, and the withdrawal calculators above can help you budget for these recurring expenses.

Tax-Efficient Retirement Strategies

Minimizing taxes in retirement can significantly extend how long your savings last. Most retirees end up in a lower tax bracket than during their working years, but poor tax planning can still cost you tens of thousands of dollars. A tax-efficient withdrawal strategy is essential for maximizing your after-tax retirement income.

The traditional approach to retirement tax planning is to have a mix of taxable, tax-deferred (Traditional 401(k)/IRA), and tax-free (Roth) accounts. This gives you flexibility to control your taxable income each year by choosing which accounts to withdraw from. In years when your income is lower, you might withdraw more from tax-deferred accounts. In higher-income years, you might draw from Roth accounts to avoid pushing yourself into a higher tax bracket.

Roth conversions are another powerful strategy. Converting some of your Traditional IRA or 401(k) to a Roth IRA during low-income years before retirement can reduce your future required minimum distributions (RMDs) and tax burden. RMDs begin at age 73 and can push you into higher tax brackets if you have accumulated significant tax-deferred savings. Strategic Roth conversions can help manage this. The retirement calculators above can help you model different scenarios to find the most tax-efficient approach for your situation.

Common Retirement Planning Mistakes

Starting too late. The most expensive retirement mistake is waiting too long to start saving. The power of compound interest means that saving in your 20s is exponentially more effective than saving in your 40s or 50s. Someone who saves $5,000 per year from age 25 to 35 and then stops will likely have more at retirement than someone who starts saving $5,000 per year at age 35 and continues until 65.

Underestimating healthcare costs. Many retirement plans fail to account for the true cost of healthcare in retirement. As discussed above, healthcare is likely to be one of your largest retirement expenses. Plan for it explicitly rather than hoping general savings will cover the gap.

Taking Social Security too early. Claiming Social Security at 62 instead of waiting until full retirement age or later permanently reduces your monthly benefit. For a couple, a coordinated claiming strategy can mean the difference between hundreds of thousands of dollars in lifetime benefits.

Ignoring inflation. A 3% inflation rate cuts purchasing power in half about every 24 years. When planning for a retirement that may last 30 years, inflation is one of the biggest risks you face. The retirement calculators above include inflation assumptions to help you plan realistically.

Being too conservative or too aggressive with investments. Being too conservative early in your career means missing out on growth. Being too aggressive near retirement risks a market crash wiping out your savings. A gradual shift from stocks to bonds as you age is the standard approach.
