3 Best Retirement Calculators To Achieve Your Dreams


Read any article about retirement planning and they will give you a number that you should use as your savings goal.

While on the surface this is great to have, the reality is that it has nothing to do with your personal situation.

What would be more beneficial to you is an easy retirement calculator that could help you determine exactly how much you need to save for a comfortable retirement.

After all, you probably ask some of these questions over and over:

  • How much money should I have for retirement?
  • How much is enough for retirement?
  • Do I have enough saved for retirement?

By finding an easy to use retirement calculator, you could answer these questions and more.

This can be difficult as you just don’t know which ones you can trust.

Luckily, I found the 3 best retirement calculators that are easy to use and take into account everything you can possibly throw at them.

As a result, they will give you a specific number that is accurate for you.

This means you can save with confidence knowing you will be able to afford your retirement and even more importantly, not run out of money in the process.

And best of all, all 3 are completely free to use!

So let’s get started looking at these online retirement calculators.

3 Best Retirement Calculators To Take Control Of Your Future

Why Use A Retirement Calculator?

A good retirement savings calculator will help you know if you are on track to retire based on your current savings.

It will also allow you to play around with the numbers if you are off.

For example, let’s say you want to achieve early retirement but are behind.

What will make the biggest positive impact on reaching your goal?

You can see if you need to increase your annual contribution to retirement accounts or if you need to change your asset allocation.

By changing the variables in your financial situation, you get a better idea of what will help you most.

Let’s look at another example of how using a retirement calculator will benefit you.

A a common savings goal number that you see in many personal finance magazines, $1,000,000.

Is this the amount you should save in your retirement nest egg?

It all depends.

I know a gentleman who is retired at 50 and has a $500,000 nest egg.

For him, this is more than enough money. He has his home paid off and lives in a state with low taxes.

He also lives a very simple life, where he enjoys reading books and woodworking.

He will easily outlive his savings. So having a $1,000,000 nest egg for him doesn’t make sense.

In fact, if he were to follow this advice, he would still be working, trying to amass that amount of retirement savings.

On the other hand, you have someone who lives just outside New York City and enjoys taking exotic vacations annually.

Even if they retire at 65, a $1,000,000 nest egg might not be enough for them.

These examples show that you cannot use a general number when it comes to planning your retirement.

You need to figure out your specific savings amount using a realistic retirement calculator.

Unfortunately, you can’t just use any of the retirement calculators you find online.

There are many things that you have to take into account.

For example, you need to consider:

  • Taxes
  • Retirement age
  • Social Security income
  • Retirement plans (traveling more, expensive hobbies, etc)
  • Paying for children’s higher education
  • One-time events (paying for a wedding, gifting money for child’s first home, etc)

Sadly, most basic retirement calculators you find from a quick online search aren’t going to allow you to enter in all of this information.

Worse, many have built in assumptions that can lead you astray.

For example, you could enter the same information into two calculators and end up with 2 drastically different results.

This is what happened to me when I used the AARP retirement calculator.

Talk about confusing!

And I won’t get into how annoying to was to wait for a new page to load after I entered each assumption either.

To take into account all of these events and get a number that you can trust, you need a calculator that is powerful.

But many powerful retirement calculators are too complicated for most people to use.

They require you to have a deep understanding of the calculator and the topic at hand.

When retirement planning, you want a quick answer that is detailed.

Not an answer that will take you days to figure out.

So here are the best calculators I found to be accurate and reliable.

#1. Personal Capital’s Retirement Planner

Hands down, this is the easiest retirement calculator that I have found.

When I first started using it, something felt familiar with it and then I realized why.

When I was working for a high net worth financial planner used a similar calculator to show our clients how much is enough for retirement.

Here is how the Personal Capital retirement calculator works.

You first create your free account with Personal Capital.

Personal Capital Button

You then link your investment accounts so Personal Capital can pull in your balances and begin to create your retirement plan.

All that is left for you is to enter your income events and spending goals.

Here is a run down of the income events you can input:

  • Annuity income
  • Inheritance
  • Pension income
  • Rental income
  • Sale of property
  • Work during retirement
  • Other retirement income

Here is a run down of the spending goals you can input:

  • Education
  • Healthcare
  • Charity/Gifts
  • Dependent support
  • Home purchase
  • Renovation
  • Vacation
  • Vehicle purchase
  • Wedding
  • Other expense

Personal Capital then runs a monte carlo simulation and shows you the likely outcome of your saving, investment growth and spending.

The thing I love about this tool is their analysis.

As you can see from the image below, my current retirement planning is in good shape, with a 95% chance of success.

Personal Capital then gives you some suggestions on how to improve your chances of hitting your retirement number.

For me, they offer 5 insights to help me save more money and help my portfolio grow, all for free.

Overall, I love this tool.

It’s simple to use, looks great, you can use this retirement calculator for couples, and you can save multiple plans.

This means it is always up to date when you log into your account.

#2. FIRECalc

FIRECalc is another free retirement planning calculator and arguably one the best tools out there.

 This one also has a ton of great features and bases its output on a monte carlo simulation as well.

The only major drawback to this calculator is how confusing it looks the first time your use it.

There is a lot of text to read and the boxes to enter in your information are easy to overlook.

You can see this in the image below.

firecalc example

What I love about this retirement calculator is how detailed you can get.

There are many more options here for inputting your portfolio because FIRECalc isn’t pulling your data like Personal Capital does.

But here are a couple things I don’t like about this calculator.

The first is the layout as I mentioned above.

It can be busy and tough to work your way through all the options when you are first using it.

Another downside is saving your plan.

You have to copy the link and then enter that link back into your browser when you want to view, update, or edit your plan.

Finally, there are 5 set suggestions you can make to see the impact on your planning.

I like how Personal Capital gives you specific, actionable suggestions to make.

FIRECalc on the other hand has you make the edits and then you have to see if they have a positive or negative effect on your retirement planning.

This results in a lot of time wasted playing around with numbers instead of knowing exactly what you should do to improve your retirement readiness.

#3. Flexible Retirement Planner

The Flexible Retirement Planner calculator is the ultimate retirement calculator when planning for your retirement.

It mimics the other two I highlighted with one big difference.

Instead of accessing a retirement calculator online, the Flexible Retirement Planner is accessed locally on your Mac or PC after you download the file.

This is great for those who mainly do their planning while at home, but could be a deterrent for those who travel a lot or want access to their retirement calculator on any device they use.

And as with the others, this calculator allows you to enter a wealth of information to tailor the plan specifically to your life and plans.

The layout is clean too, as seen in the image below. Using it is very straightforward.

However, this calculator does require some personal finance knowledge in order enter in every assumption correctly.

I see it as a fit for those who enjoy using spreadsheets the most.

Also, since you download the program, you have to be aware of changes in tax law.

I tried to find out if you can download updates so that tax changes are incorporated, but didn’t see any documentation.

This is something to keep in mind as taxes can have a major impact on you having a secure retirement.

The feature I like most about this retirement tool is the Sensitivity Analysis.

It is a heat map that shows you how vulnerable your retirement plan is to changes in your spending, portfolio rate of return, or estimated investment return.

Which Is The Best Retirement Calculator?

Now that we have covered 3 great calculators, which one is the best retirement calculator?

Unfortunately, only you can make the final decision.

All 3 offer detailed analysis and are realistic retirement calculators in that they give you information that you can trust.

With that said, I will suggest that most users try out Personal Capital first.

This is because the layout is clean and very simple to use.

If you have never run the numbers for your retirement, Personal Capital makes it easy.

For example, my wife is not a tech person and can easily update and follow along with Personal Capital.

Before we used this tool, we were using FIRECalc and it was too much for her.

And since we aren’t near my computer when we discuss our finances, having access to Personal Capital on my tablet is great.

Finally, I think Personal Capital is the perfect retirement calculator for couples.

My wife can follow along and update it, without feeling overwhelmed.

Plus she can see the current balances in all of our accounts, like our Roth IRA and tradtional IRAs in a clean layout.

My second retirement calculator choice would be the Flexible Retirement Planner.

The tool is great, it updates easily with a click of a button on the main screen, and you can save it locally.

But it takes a little more understanding to create a plan since you can edit just about every input possible.

And for some, having the ability to only access it on the computer you download it to can be a hassle.

Lastly, FIRECalc is great and it was the tool I was using before Personal Capital came along.

I will admit though, it did take me a couple of times using it before I felt comfortable with the answer.

There is just so much text and places to input numbers that you can easily overlook one.

And this could have a major impact on the results you see.

But it is very customizable to different scenarios and once you get a hang of it, it is very powerful.

Frequently Asked Questions

frequently asked questions

There are a lot of questions about retirement calculators I get asked.

Here are the most common ones.

What should I look for in a retirement calculator?

When it comes to online retirement calculators, you need to find one that allows you to input as many variables as possible.

While this will make it more time consuming to get your answer, the reality is this will offer better actual results.

Here are a few basic inputs you need a calculator to have:

  • Current age
  • Life expectancy
  • Current Retirement savings balance
  • Retirement expenses
  • Social Security retirement benefits
  • Pension plans balance

In addition to these inputs, you want to focus on online calculators that offer monte-carlo simulations.

This allows for many random scenarios to get a much higher accuracy of the tool.

Should I input Social Security benefits?

Yes you should enter in all Social Security benefits and pension benefits.

This is important income that will effect how much money you need to save for retirement and the rates of return you need to earn.

For example, if you have a monthly income of $5,000 from these sources and need $70,000 annual income to live comfortably, you will need to save a lot less money than if you didn’t have this income.

What if I can’t reach my retirement goal?

If after entering all the information you find you cannot reach your goal, don’t give up hope.

You don’t have to forget about enjoying your golden years and work for the rest of your life.

Can you delay Social Security to full retirement age?

Maybe scale back your plans a little bit?

Doing either of these could make it possible to still retirement.

The last thing you want to do is ignore your risk tolerance and put your savings at risk.

It is much smarter and safer to dial things back than it is to go all in.

Final Thoughts

So there are 3 of the best retirement calculators out there.

I recommend all 3 but think that the one from Personal Capital stands out among the group.

This is because of its clean look, ease of use by everyone regardless of financial planning knowledge, and its ability to be accessed on any device.

If you have any interest in planning for and saving for your retirement, you have to know how much money you will need.

You cannot just wing this.

If you do, you could end up working a lot longer than you need to or want to.

By having a customized number specific to your individual circumstances, goals and plans, you can save and be relaxed knowing you are going to reach your saving goal on your terms.

So be sure to take the time to plan for your retirement using any of these retirement calculators.

They will give you a much better idea of where you stand than any basic calculator most sites offer.
