2 of the Best Retirement Calculators (2024)

As American workers began to shoulder more of the responsibility for funding their retirement years, retirement calculators became a popular tool to help people achieve their goals. A Google search for “online retirement calculator” garners tens of thousands of hits.

In this article, we look at two popular retirement calculators available online. They do the best overall job we've seen of translating sophisticated retirement income planning methods into an understandable and easy-to-use layperson’s planning tool.

How Retirement Calculators Work

If you're going to use a calculator, there are some key facts you'll need to have at your disposal. These include:

• Projected age of retirement
• Annual income
• Any income you expect to have when you retire
• Current retirement savings
• Whether you plan to work during retirement
• Where you plan to retire
• Investment style
• Estimated living expenses
  

Once you plug in this information, the calculator you use should give you an idea of whether you're on track to meet your goals or which direction you need to take to achieve them.

The most effective and useful calculators let you model various retirement scenarios, taking into account the variables that can affect how long your money will last so that you can save and invest accordingly.

T. Rowe Price Retirement Income Calculator

TheT. Rowe Price Retirement Income Calculator is widely lauded for its strong emphasis on income planning. It enables you to project your monthly retirement income based on various planning scenarios. It projects your monthly shortfall for each scenario, if any, and shows the likelihood of your savings lasting throughout your retirement. It then offers options for making up for potential shortfalls.

You can compare scenarios side by side while changing the variables and assumptions to see their effect. It also has a built-in Monte Carlo simulation tool to help you see how your retirement savings will fare in various market conditions.

The major drawback is that it calculates only one retirement age at a time. If you and a spouse plan to retire at different points, you would need to run two separate calculations.

The presentation is straightforward for the level of sophistication that the tool employs. The interview process is somewhat involved, but there is plenty of pop-up support along the way.

You can expect to spend up to 20 minutes inputting data if you have all of your financial information at hand.

MaxiFi Planner (formerly ESPlanner)

Many retirement calculators do not allow for the varying tax consequences of different sources of income, which can have a significant impact on projecting your retirement income. The MaxiFi Planner accounts for variable taxation, which can help you achieve greater tax efficiency using Monte Carlo simulations or other financial models.

It also allows spouses to plan for two different retirement dates, a notable flaw in the T. Rowe Price calculator.

The first thing you may notice is the detail of the input screens. The added detail allows for greater flexibility in entering planning assumptions.

The MaxiFi Planner requires some upfront reading to understand the process. You can choose from several different planning modes, such as Conventional or Economics. It offers two other modes, Upside Investing and Monte Carlo, which you need to purchase.

A self-help guide can be accessed by clicking on any underlined word.

MaxiFi has the following noteworthy features:

• It provides separate inputs for the assets of each spouse.
• It assigns a different tax status to each asset, such as after-tax, pre-tax, and no-tax.
• It calculates income taxes automatically based on your data inputs.
• It allows for variable inputs of expenses and income to account for temporary situations or anticipated changes in the future, such as downsizing, the sale of a business, an inheritance, or paying for college.

Once all the assumptions and variables are finalized, the program works with a simple click.

You may find the detailed output a little difficult to understand at first, but it provides several pages of numbers and graphs that are easily clarified. The only real negative is that you have to assume age 100 for life expectancy, and you cannot specify the payout type for a pension, such as single or joint life.

And if you don't want to spend a lot of time reading and combing through financial details, MaxiFi may not be for you.

How to Save for Retirement

One of the biggest hurdles that most people experience when it comes to saving for retirement is starting the process. But there are certain things you can do that can take the guesswork out of saving.

You can accomplish this by enrolling in programs that allow you to save using automatic deductions. For instance:

• Enroll in an employer-sponsored plan, such as a 401(k) or 403(b). You choose how much you want to stash into your retirement account. Your employer deducts this amount from every pay on a pre-tax basis. This not only takes the onus off you, but it also reduces your annual income and lowers your tax liability for that year. And if your employer provides a matching contribution, you get extra money for your retirement fund.
• Open an emergency fund. You can choose from a range of options, including savings accounts. Like the employer-sponsored account, you can choose to have the money transferred from your checking account automatically each time you get paid. Once you have a high balance, you can earn more by investing in an account that pays higher interest.

And don't forget, there are other options available, including individual retirement accounts (IRAs) and other non-traditional savings vehicles like certificates of deposit (CDs) and brokerage accounts that you can use to invest for your retirement.

If your age is preventing you from saving for retirement, just remember that it's never too late to start. Keep in mind that you'll probably need to save more the later you start.

Consider speaking with a financial professional to help guide you in the right direction. They can assist in choosing the right investment mix to help you meet your goals and stay on track.

The Bottom Line

Online retirement calculators are good tools for estimating how much you need to save to provide sustainable income for your lifetime. The T. Rowe Price Retirement Income Calculator and MaxiFi Planner are two of the best tools.

It is important to keep in mind that retirement calculators rely on accurate information and realistic assumptions.

In other words, if you put garbage in, you get garbage out. Before using any planning calculator, plan to have all of your relevant financial and benefits information on hand and spend some time thinking about your goals for retirement.
