Figuring out if you can retire securely can sometimes feel like the most complicated math problem ever.  Just figuring out which retirement number to worry about can be perplexing.  And then there is the further complication of knowing how they all fit together.

Here is your guide to the 16 retirement metrics that are most important.

Retirement Number 1: Your Financial Independence Number

Financial independence (FI) is achieved when you have enough savings or passive income to cover your expenses for as long as you will live.

Most FI proponents suggest that you can achieve FI when you have amassed enough savings to cover 25 times one year’s worth of living expenses. So, if you spend $100 thousand every year, then you need $2.5 million to achieve FI. (Don’t worry if you intend to live much longer than another 25 years, the calculation assumes that returns on your savings will enable you to withdraw adequate funds forever.)

This FI standard may or may not apply to you depending on who you are now and what your future holds. For example, if you have a pension or you intend to downsize your home in the future, you may need less in savings to achieve Financial Independence now.

The best way to figure out when you can declare financial independence is by creating and maintaining a detailed financial plan. Recommended by ChooseFIJD RothCanIRetireYetEarlyRetirementNow and the Retirement Manifesto, the NewRetirement Retirement Planner is the best tool for tracking FI.

Retirement Number 2: Financial Independence or FI Ratio

Your Financial Independence or FI ratio will tell you how close you are to achieving FI.

You calculate your FI ratio by dividing your net worth by your FI number. The resulting percentage will mark your progress toward FI.

So, if you need $1 million to achieve FI and your net worth is currently $500 thousand, then you are 50% of the way to FI.

NOTE: Your FI Ratio is a good way to measure your retirement readiness. Discover your FI in the NewRetirement Planner.

Retirement Number 3: Your Social Security Start Age

You probably know that the later you start Social Security, the higher your monthly benefit will be.  Even so, a lot of people start getting checks as early as possible because they think they will get more money from the additional years of collecting benefits than they will from a bigger benefit later on.

Use the NewRetirement Retirement Planner to assess different Social Security start ages on your overall finances. Try out different start ages and look to see how your out of money age, lifetime debt, cash flow, estate value and lifetime taxes are impacted.

Did you know? Did you know that the lumpsum value (the amount you could get if you were to receive all of your Social Security in one lump sum today) of your Social Security is likely to be greater than the total of all of your savings?

In 2014 the average lump sum Social Security benefit was around $300,000. The maximum benefit was around $575,000 for males and around $680,000 for females. Compare these numbers to the average amount of savings held by a 66 year old — $67,000 — and you’ll appreciate just how valuable Social Security can be.


Retirement Number 4: How Long You Will Live

Another important retirement number is knowing how long you will live.  Estimating your longevity will impact your decisions about how much savings you need — the longer you live, the more life you need to pay for.

Of course, no one can really predict how long they will live. However, there are some good longevity calculators that can help you make a relatively good prediction — you may just want to add 5 or 10 years to any estimate just in case!

Retirement Number 5: How Much Monthly Guaranteed Lifetime Income You Have

Guaranteed lifetime income — money that you will receive every month (no matter what) for the rest of your life (no matter how long you live)  — is the real secret of financial security.

In fact, retirees who report having guaranteed income that exceeds their spending report less stress and an overall happier retirement.

Common sources of guaranteed lifetime income include: Social Security, some pensions, and lifetime annuities — add them all up to get this important retirement number.

Many retirees who have adequate savings buy a lifetime annuity to insure their retirement income.  You can estimate how much income your savings could buy or how much desired income would cost with an annuity calculator. You can also model an annuity purchase in the NewRetirement Planner as part of your overall plan.

Retirement Number 6: Inflation Outlook

Inflation is an economic concept that describes the increase in prices.  If inflation is rising at 3% annually, then something that costs $100 today will cost $103 a year from now, $106.09 in two years and it keeps accumulating.

Inflation can be less noticeable when you are working because your salary generally keeps pace with the increases in costs.  However, inflation in retirement – when you are living off a fixed set of assets – is a whole other matter. You have a fixed amount of money that can buy less every year.

Here are some funny quotes that describe the dangers of inflation:

  • “Inflation is when you pay fifteen dollars for a ten-dollar haircut you used to get for five dollars when you had hair.” -Sam Ewing
  • “Inflation is as violent as a mugger, as frightening as an armed robber and as deadly as a hit man.” -Ronald Reagan
  • “Inflation is the crabgrass in your savings.” -Robert Orben

Predicting inflation is an important component of preparing for retirement.  According to this chart, inflation in the United States was 2.28% in 2019.  That’s much lower than the highest rate of 13.29% in 1979. The average rate of inflation in the U.S. in the 21st century is 2.4%, though since the Great Recession of 2008 the average is only 1.7%.

The NewRetirement retirement planning calculator enables you to make your own predictions about inflation and easily change them to see the impact on your finances now and well into your future.  You can even put one number for general inflation, another for housing inflation and yet another for medical costs which have been rising much faster than other services.  This can greatly increase the accuracy of your retirement plans.

Retirement Number 7: Rate of Return on Investments

If you have retirement savings, knowing how much that money will earn for you is important.

Ideally, you are earning a rate of return that is better than average.  What is average you ask?  The answer is, “it depends.”

According to Ycharts, average returns over the last few years look like this:

  • For the last 5 years, the average return for the S&P 500 has been 75.15% while the average return for mutual fund investors has been 8.9%.
  • Over the last 10 years, the average return for the S&P 500 has been 16.85% and 7.12% for the mutual fund investor.
  • Over the last 15 years, the average return for the S&P 500 has been 11.26% and a mere 6.02% for the mutual fund investor.

As you can see, the rate of return varies greatly depending on the time period you are looking at as well as the type of investment.  And, this is just a simple comparison of two investment options.  However, depending on how much retirement savings you have, predicting a rate of return can be critical to your financial security.

The NewRetirement retirement planning calculator lets you enter a rate of return for each individual account — you can even put in an optimistic and a pessimistic prediction — and it is easy to change and immediately see the impact any change would have on your financial well being.

Retirement Number 8: Out of Pocket Healthcare Costs

This number is easy — if you want to go with averages and the opinions of various experts in the field.

According to Fidelity’s Retiree Health Care Cost Estimate,

a 65-year old couple retiring in 2019 can expect to spend $285,0001 in health care and medical expenses throughout retirement compared with $280,000 in 2018.

And, this does not include any money that may need to be spent on a long term care need.

However, if you want a more personalized estimate, use the NewRetirement retirement planner. You can calculate current medical costs, see what early retirement medical might cost you and get a detailed estimate of your out of pocket Medicare expenses. The system will also help you figure out how to cover long term care.

Retirement Number 9: Estimated Monthly Retirement Spending

Knowing how much you will spend is another critically important retirement number.  The more you will spend, the more savings and income you will need.

There are various ways to predict your spending.  Different experts have different suggestions for figuring out your spending, some say that you will spend:

  • 85% of what you spent while working.
  • The same as you spent while working.
  • More when you first retire, then less as you grow older.
  • Much less in retirement, because you dramatically cut costs to make ends meet.

The NewRetirement Planner enables you to plan for any of these spending possibilities. You can even create a detailed projected budget in over 75 different categories, varying your spending (as well as tax treatment) by year. You can even set necessary and optional spending levels.

For a very basic view of your average retirement expenses, use the simple retirement calculator.

Retirement Number 10: How Much is Your Home Worth

Many 50, 60 and 70 year olds today have put more effort into buying a home and paying their mortgage than they did on saving for retirement.  As such, your home is an important source of retirement wealth.

More and more retirees are downsizing or getting a reverse mortgage as a way to use their hard earned home equity to fund retirement.  You can use the NewRetirement planner to see the impact of tapping into your home’s value.

Retirement Number 11: How Much You Have Saved

This should be easy.  How much do you have saved for retirement?

The trickier part is knowing how much those savings will be valued in the future. When will you make withdrawals and for how much?  What kind of rate of return will you get?  Will you add anything to your savings?

Retirement Number 12: Your Retirement Age

Retirement age used to be 65 for most everyone.  These days we aren’t even sure exactly what “retirement” means anymore.  Many more people are quitting their job only to get another career or part-time gig.  Other people are phasing out of work by reducing their workload before they fully retire.  And retirees are more active now than ever before.

You might be able to define your retirement age as when you stop earning income from work, but then we get into the definition of work. Many people these days have side hustles and passive income sources.

So maybe the new idea of a retirement age is the age at which you need to start really relying on withdrawals from savings to make ends meet.

Retirement Number 13: How Much Savings You Need for Retirement

This is THE retirement number — the question that everyone wants answered.

Of course, the answer to this question depends entirely on your answers to all the other questions. And the best way to get a reliable answer from this jumble is to use a good retirement calculator — one that is detailed and that can be completely personalized.

Retirement Number 14: Your Net Worth

Net worth is all of your assets (savings, home equity and more) minus all of your debts.

Net worth is considered the most accurate measure of wealth. It is a precise number that is an accurate gauge of your financial health and it can be easily tracked.

Want to know your net worth? Use the NewRetirement Planner to track your number and discover ways to improve upon where you are right now.

Retirement Number 15: Projected Estate Value

It is useful to know your net worth now, it can also be useful to know your net worth at your projected life expectancy. This is the projected value of your estate.

Knowing your projected estate value is useful for planning to minimize taxes and for making plans for your heirs.

Retirement Number 16: Value of Your Emergency Funds

If 2020 has taught us anything, it is that we definitely need emergency funds.

A cash account may be the best source for a finite amount of money, but there are other ways to cover unexpected costs. Consider this guide to the best and worst sources of emergency funding.
