Our Selection Criteria

There are many similar tools out there that say they are the best. But, we went through them with a fine-tooth comb to pick the best of the best. Our selection criteria included four main considerations:

Simplicity: Retirement planning is very complicated. The job of a best retirement calculator is to make the complicated simple.

Flexibility: Too many retirement calculators rely on assumptions for results. However, you are not average and you need to be able to change anything and everything that might impact your financial future. You also want to be able to change and update your information over time.

Comprehensive Answers: We chose tools that give accurate, and immersive answers.

Customized & Reliable Results: This is your retirement. You need your results to be custom and personalized.

1. New Retirement Retirement Planning Calculator

NewRetirement offers two powerful tools — the NewRetirement Planner, the best retirement planning tool available on the internet and a quick retirement calculator (fast general answers but not as comprehensive or personalized). The information you enter reflects you, your current situation, your goals for retirement. It shows you the many different ways you can achieve those goals.

This tool gives you power over all the variables that might impact your retirement and minimizes assumptions. NewRetirement is highly customizable.

You can set your own values for longevity, inflation rates and investment returns, and saving and income levels or tap home equity. The calculator gives you results that are more accurate for your situation.

NewRetirement is a great calculator if you have significant retirement savings. It’s even better if you are not as prepared as you would like to be.

What to Expect

The New Retirement calculator has an in-depth breakdown of what you have now, what you’re projected to have at retirement, how long it should last, and everything that you can think of.

It is easy and doesn’t take long to get started and access great information. However, this tool is designed to be used over time.

As such, you begin by creating an account and entering some basic information. Just an email and password.

You will next get customized charts about your current situation.

One of the original analyses they offer is a comparison of how you are doing and not against averages. See how your finances compare to those in your own zip code.

You’ll get a savings analysis that shows in simple language how long you can expect your savings to last into retirement.

You will also see how much you will likely need to maintain the standard of living that you’ve got. You’ll see your current net worth, retirement cash flow, and then it gets really interesting.

You can add more information or run different scenarios. You instantly see how the changes impact your finances now and into your future.

The calculator does more than tell you if there are shortcomings in your plan. It also gives you real-world options for fixing it.

You’ll also see how your situation could improve if you choose any of the suggestions. It shows how you compare to others in your area.

All your information is saved so you can maintain your retirement plan over time.

You’ll have options for entering the information you’d expect, such as your age and how much you’ve already saved and invested toward retirement.

And instead of expecting you to have all of this information at hand, there’s an optional worksheet that helps you calculate this.

This calculator will make you work hard. The results give you valuable information that can help you plan better. It doesn’t use simple language as some others, but it does what a retirement calculator should do.

What to Expect

After a lengthy account creation process (name, address, etc.. ), you’ll be asked detailed questions up front. Such as how much of your investments are allocated to stocks or bonds. Once you’ve made it through the initial pages, you’ll see a short video that breaks down your information.

The video offers a projection of how your savings and investments should carry you through retirement, and whether you’ve got a shortfall.

If you don’t like what you see in the summary, you can adjust your numbers without backtracking to the beginning.

You can change details, such as your monthly retirement savings contributions and when you want to retire. You get instant, updated results based on those changes.

You’ll see how much you will likely have at retirement, based on your current course, and how much T. Rowe Price thinks you will need. Then you’ll have a few options for correcting any shortfall, with more information on each to help you choose which is the right path for you.

The detailed analysis has 15 questions, and you’ll need about 15 minutes, maybe more, to go through it.

With the short version, you get the basics. This is a great jumping-off point if you’re not quite ready to go in-depth with a retirement calculator.

What to Expect
example of american funds' retirement calculator

Like other calculators, you’ll be asked your birth year, income, dollar value of all investments combined, and how much pension you might receive at retirement. With the in-depth version, expect more questions in greater detail.

On the Quick Analysis Results page, you’ll see a chart with the projected growth of your current savings and investments. The bar is set at the top end of the chart, which shows your projected goal.

If there’s a shortfall in your current plan, the analysis suggests how much you’ll need to save. The goal would be to meet 80 percent of your current income during retirement.

With the in-depth calculator, you’ll get results that are more tailored to you instead of ones generated based on assumptions.

Instead of guessing that you’ll need 80 percent of your current income at retirement, you can adjust for your own needs.

  • Can be as detailed or as short as you like


  • Nothing extremely in-depth

4. AARP Retirement Calculator

The AARP retirement calculator is another user-friendly calculator. It’s not overly technical, but still covers all the important bases. It’s not as intimidating as some others.

The results page is interactive, too, which makes it easier to try out different scenarios.

One thing that’s different about this one is a lifestyle question. You can set your lifestyle expectations up front instead of asking you to guess how much you’ll need

What to Expect
example of aarp's retirement calculator

You’ll be asked the typical questions, including how much you contribute to retirement savings each year. And you can lump contributions into one category, for simplicity’s sake, or add separate line items for your 401(k), IRA, and others.

And for some entries, you can enter dollar amounts, or let the calculator estimate for you. For example, if you already know what you’re projected to receive in Social Security benefits once you retire, you can enter that amount. Or the calculator will estimate it for you.

On your results page, there’s a graph that shows what you’ll need to retire compared to what you’ll likely have. But there’s also a plain-language explanation at the top of the chart that puts everything into perspective in short form.

You’re given the dollar amount you’ll need to retire, and below that is how much you will have saved if you stay on the same track.

On the final page, you’ll have the opportunity to play with numbers a bit. At the top, you’ll see whether your plan is “On Target” or “Over Budget,” meaning you’ll need to save more.

Using a slider, you can adjust your lifestyle to more modest or more extravagant. And you can also adjust your retirement age. The chart from the previous page appears, and automatically adjusts based on how you move the sliding scales.

When you select “View Report,” you’ll see a graph that shows the rate at which your savings could grow over time. Below that, you’ll have a breakdown of what all of those numbers mean.

This includes how much you can expect to receive monthly, to how much that’s equal to in today’s dollars.

Another interesting feature with this calculator is the tax estimate. You’ll learn how much, if any, of your retirement income, is likely to be subject to taxes.
