Types of Retirement Accounts in the U.S.

Finding the right retirement plan is the first step to a comfortable retirement. There are three main types of retirement plans in the U.S., each offering unique tax or growth advantages:

• Employer-sponsored plans
• Individual retirement accounts
• Government programs

Did you know you can open multiple retirement accounts at once? For example, someone might contribute to a 401(k) through their employer, open a Roth IRA for additional tax advantages, and rely on Social Security as a baseline income source. Here’s a quick overview of popular retirement savings accounts.

401(k)

A tax-favored retirement savings plan offered to U.S. employees under the Internal Revenue Code. Employees contribute a percentage of their income to their retirement account, and the employer may match some of what is contributed, depending on the plan.

Solo 401(k)

A special type of 401(k) plan for self-employed individuals or freelancers. It allows you to make contributions to your account both as the employee and the employer, which can significantly increase the total amount saved each year.

Traditional IRA

In a Traditional IRA account, you get a tax deduction upfront on contributions, but withdrawals are taxed after retirement. If you earn $80,000 and you get a $6,000 deduction, you are taxed as if you earned $74,000.

Roth IRA

In a Roth IRA, you pay tax on the money you contribute, so you do not owe any taxes when you withdraw it. In return, the account grows tax-free, and qualified withdrawals in retirement are also tax-free, subject to certain account requirements. Because each account type has different tax rules, contribution limits, and withdrawal conditions, retirement planning often involves choosing the right combination of accounts to match a person’s income, employment situation, and long-term financial goals.

Choosing the Right Retirement Planning Tool

There is no one-size-fits-all solution when it comes to retirement planning. The account type you choose, the age you retire, and the kind of tax benefits you get depend on your specific retirement accounts, as well as local or federal tax rules. Before locking in a retirement plan, make sure to study the impact of each of the following factors on your net returns and account balance:

• Market conditions
• Tax rules
• Individual account or plan rules
• Your specific spending needs & habits

Retirement Withdrawal Calculators

Saving for retirement is only half the challenge. You also need a plan for how your savings will be used once you stop working. A typical withdrawal plan works like this:

• Start with a rough estimate of your account balance when you retire. This is the starting point of your payout schedule and must guide your choices before and during retirement.
• From period 0 onward, your account starts earning a constant annual return. Interest compounds based on the withdrawal frequency you choose.
• You also begin the lifelong journey of withdrawing a planned amount each period on a monthly or yearly basis.
• If needed, you may directly factor in extra withdrawals in specific periods. Keep in mind that, in practice, withdrawals are subject to specific account rules or tax laws.

Our collection includes several tools designed to help model retirement income. We model our calculators based on common payout strategies used in the U.S. Basic Retirement Withdrawal Calculator Use this calculator to find out if your retirement plan is sustainable and tax-efficient. Plug in a few basics, and the sheet then instantly tells you how long your money will last using a simple input panel, a quick results table, and a year-by-year payout schedule. Retirement Withdrawal Calculator (4%) This retirement planning tool is designed to withdraw only 4% of your account balance in year 1 and then automatically adjust that amount for inflation every year after that, until the date of the last payout. The goal is to make savings last. Retirement Withdrawal Calculator (Bucket Strategy) This calculator uses the bucket strategy to fund retirement income over time and test income stability under different return assumptions. The sheet models withdrawals from each bucket and tracks sustainability year by year.

Typical inputs include:

• Starting savings balance
• Contribution amounts
• Interest or return rates
• Retirement age
• Withdrawal amounts
• Inflation assumptions

Using the Calculator: Instructions and Tips

Each calculator comes with a clean user guide to help you map out key user inputs, calculations, and data outcomes. To make the best use of these calculators, consider the following: Do Your Homework: Use of these calculators must align with your specific retirement account rules and current IRS regulations. Before making any big financial decisions based on this sheet, consider your full financial situation and consult a qualified professional such as a Certified Financial Planner, CPA, or licensed financial advisor. Run Multiple Scenarios for Better Retirement Planning: For example, you can duplicate a sheet to see how different return rate assumptions affect your account totals. Many people run a Conservative, Baseline, and Optimistic scenario to study the best and worst possible retirement scenarios. This is good for exploring what could happen, but it is not a true market simulation.
