10 best retirement calculators

1. New Retirement

new retirement logo
NewRetirement’s retirement planning calculator is a personalized and extremely comprehensive system. The information you enter reflects you, your current situation, your goals for retirement and the many different ways you can achieve those goals.

This tool gives you power over all of the variables that might impact your retirement and minimizes assumptions. From setting your own values for longevity, inflation rates and investment returns to enabling you to vary your spending, saving and income levels or tap home equity, NewRetirement is highly customizable — giving you results that are more accurate for your situation.

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

What to Expect

What you get with the New Retirement calculator is an in-depth breakdown of what you have now, what you’re projected to have at retirement, how long it should last, and nearly everything that you can think of in between.

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 (just email and password) and entering some basic information.

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 just 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 and instantly see how the changes impact your finances now and into your future. And, instead of simply telling you that there’s a shortcoming in your existing plans, this calculator gives you real-world options for fixing it.

You’ll also see how your situation is projected to improve if you choose any of the suggestions, and how you compare to others in your area.

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


  • Personalized
  • Comprehensive
  • Easy to use
  • Comparison analysis
  • Gives suggestions for fixing issues


  • While it is easy to get started, it is best used over the long-term

2. T. Rowe Price

t rowe price logo
The T. Rowe Price calculator offers a straightforward but flexible retirement planning tool that works whether you’re early in the retirement savings mode, or already retired.

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 quickly without navigating off the page.

This calculator will make you work hard, but 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. And once you’ve made it through the initial pages, you’ll see a short video that breaks down your information with a projection of how your savings and investments should carry you through retirement, and whether you’ve got a shortfall.

One interesting thing about this calculator is that 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, and 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.


  • Offers flexibility based on the stage of retirement
  • Includes a worksheet to help you with calculations
  • Video-breakdown of results
  • Easy to edit


  • Can be complicated
  • Lengthy process

3. American Funds

The American Funds retirement calculator has two versions. There’s the short version, called Quick Analysis, and the full one, called the Detailed Version. The short version has 4 questions and takes about 5 minutes to complete.

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, which 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, which is an interesting feature. The bar is set at the top end of the chart, which shows your projected goal. And if there’s a shortfall in your current plan, the analysis suggests how much you’ll need to save to meet the projected goal of 80 percent of your current income during retirement.

When you’re ready for the in-depth calculator, you’ll get results that are more tailored to you instead of ones generated based on assumptions. For example, instead of guessing that you’ll need 80 percent of your current income at retirement, you can adjust for your own needs.


  • Two calculators based on your needs and availability
  • Can be as detailed or as short as you like


  • Nothing extremely in-depth


aarp logo
The AARP retirement calculator is another user-friendly calculator that’s not overly technical, but still covers all of 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. Instead of asking you to guess how much you’ll need, or assuming that you’ll need a certain percentage of your current income, you can set your lifestyle expectations up front.

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.


  • Simple and easy to understand
  • Easy to fill out and adjust
  • Graphical description of what you need


  • Can only be used if you have already retired
  • Big range on rate of returns options

5. Bankrate

grey and white bankrate logo
Bankrate has a bit more than just a retirement calculator. It’s both simple and complex because there isn’t just one — there are several, each with a particular focus. The comprehensive yet separate nature of this collection of calculators might be overwhelming for some people, but it might be just right for others.

You’ll see an extensive list of calculators that you can choose from. Examples include a calculator for 401(k) contributions, 401(k) with Roth IRA, 403(b), Retirement Planner, Social Security Benefits, Asset Allocation, and many more. For the purpose of this article, we’ve selected the Retirement Income Planner calculator.

What to Expect
example of bankrate's retirement calculator

Bankrate’s calculators are different because each one is focused on one issue. Instead of page after page of inputting your information, each calculator has a few fields to fill out, and the results happen on the same page with a chart.

You can adjust your information to see how it affects the outcome. And what you’ll get is an analyzation that tells you how much your current savings and investments will yield in retirement income once you need it. You can account for inflation, or not. It’s your choice.

When you select “View Report,” you’ll see a graph that shows the rate at which your savings is projected to grow over time. Below that, you’ll have a breakdown of what all of those numbers mean, from 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. If you’ve put most of your savings into tax-deferred options, such as a 401(k) or IRA, you’ll earn interest tax-free and only be taxed on what you withdraw.


  • Multiple calculators that focus on one thing
  • Easy to adjust information
  • Graphical report
  • Offers tax estimation


  • Multiple calculators on one page can be overwhelming

6. Personal Capital

personal capital logo
Personal Capital is a financial planning site that offers many tools for budgeting and controlling your finances. Part of their financial dashboard tool is their Retirement Planning Calculator. It uses real-world data to provide you with the information you need to invest in your retirement.

The biggest difference between this calculator and others is that it uses your real investments, income, and savings to calculate what you need to retire. It will also run a Monte Carlo Analysis. The analysis runs 5000 different scenarios to test what could happen to your investments should certain events occur.

Taking the probability of these events occurring, it applies that probability to your retirement to tell you the outcome of your finances, whether good or bad.

What to Expect
example of personal capital's retirement calculator

Personal Capital’s calculator allows for major customization and personalization. If you already have their Financial Dashboard, the calculator automatically pulls your investment information from the other accounts. You can control how much money you save per year. You can add income events, spending goals as well.

The calculator will show you a cash flow table with all of your spending and savings. Based on the data it receives, the calculator will give you a graph of what assets to invest in your retirement savings. It also gives you an overall snapshot of your financial future.

You can also save your profile to view it later or change values around.


  • Utilizes real data instead of assumptions
  • Easy to use and read
  • Graphical results
  • Easy to manipulate


  • Must already have a Financial Dashboard tool with Personal Capital

7. Vanguard

vanguard logo with ship
The Vanguard Retirement Nest Egg Calculator is another easy to use calculator that gives you a quick snapshot of your retirement savings and investment. The inputs are all based on sliders and you are not required to submit personal information such as your name, age, etc.

While simple in design, it offers a lot of useful information based on an analysis of the probabilities of multiple investment scenarios. It is easy to change your inputs and test other options.

What to Expect
example of vanguard's nest egg retirement calculator

The calculator is only one page and only requires six data entries: how long your investment should last, your current savings, your current spending, and how your savings are allocated based on cash, bonds, and stocks. These data entries can be changed quickly and allow you to run multiple scenarios.

There are two graph options you can view: “How long will your savings last?” and “Projected savings balance”. The first graph shows you if and when your savings will start dropping off. It also tells you the probability of your investment lasting for however long you chose it to.

The second graph shows how your balance might change over your years of retirement. The graph has three different colors to represent the range of probability where your investment may fall.

This is because the analysis runs 100,000 different scenarios and ranks them from best to worst. You can see where your investment may fall and the chances of it being better or worse.


  • Quick and efficient
  • Easy to change your inputs and run multiple scenarios
  • Information presented in a concise manner


  • No in-depth analysis
  • Data based on assumptions and chance

8. Financial Mentor

grey and white financial mentor logo
Financial Mentor’s Ultimate Retirement Calculator is based on real-world experience from its creator, Todd Tresidder. Each input area brings up a brief explanation of what it is and what to enter.

The calculator requires a good amount of information on your part but it is not as extensive as the other calculators. The analysis portion is only based off of a simple average-return calculation and does not take outside investment factors into consideration.

What to Expect
example of financial mentor retirement calculator

As stated, you will need to input a lot of data but the form walks you through it with comprehendible explanations. You won’t be bogged down by all the information you need to put in. The interface is easy to scroll through and adjust data as needed.

You will need to know (or at least guess) any one-time, and monthly incomes as well as post-retirement income.

Your results will not only show you what you need to save, but it will tell you your savings at retirement as well as any surplus you might have. Then it breaks down your investments and savings by year into a spreadsheet.


  • Lets you input a variety of information
  • Breaks down your results in an efficient format
  • Based on real experience


  • Does not show the probability of failure
  • Retirement age must be higher than current age

9. Market Watch

The main use of the MarketWatch Retirement Calculator is to determine what age you can afford to retire at. It only requires three inputs via slider to give you a graphical result. However, you can utilize their advanced settings to make more detailed changes.

The results come in three different graphs showing your held assets, future income, and retirement spending. The graphs are easy to read and jump between. Adjustments are fairly easy to make both on the sliders and manual input sections.

What To Expect
example of market watch's retirement calculator

You only really need to know the age you wish to retire at, your current age, current salary, and annual savings. You can also go through advanced settings to adjust general assumptions, tax rates, and inflation assumptions.

The calculator does not require another click for running other scenarios. Simply make your adjustments and the graphs update.

You can get a good estimate of what your assets will be at retirement age, your total income, and retirement spending. The retirement spending graph in particular shows when you will have an active, less active, and more active lifestyle.

You can either enter your first-year expenses or let the calculator estimate it for you. The calculator also lets you include a spouse.


  • Very easy to use and update
  • Concise information with good explanations
  • Suggestions for improving your savings


  • The sliders can be tricky to adjust
  • While good for a quick analysis, it doesn’t provide many details


10. Chase

The results show you the probability of success and how long your money will last.

You can also adjust for optimizing by either retirement years, living expenses, or extra savings. These change your result based on the data you previously inputted. Once you submit your results, you are given a summary that is easy to read and comprehend.

Chase gives you some suggestions to improve your investments. They also offer additional resources.

What to Expect
