What is a Retirement Calculator?

A Retirement Calculator is a valuable tool for anyone who has ever wondered “How much money do I need to retire comfortably?”

Its main purpose is to help people better plan their finances so they can hit their retirement goals and not have to worry about their monthly expenses once they leave the workforce.

A Retirement Calculator requires some basic information such as:

  • An individual’s current age
  • Pre-tax income
  • How much of their income goes to retirement savings
  • How much they currently have in their retirement fund
  • When they plan to retire

Using these personal details, it can quickly estimate how much an individual’s retirement savings will be once they reach their desired retirement age.

Different types of Retirement Calculators can also answer lots of other important questions about retirement and financial planning such as:

  • How much should I save for retirement?
  • How long will my retirement savings last?
  • What is my monthly budget when I retire?
  • Am I on the right track to a comfortable retirement?
  • How much do I need to retire early?
  • When can I retire?

The answers to these retirement questions largely depend on how a Retirement Calculator is designed and what equations it uses.

How Does a Retirement Calculator Work?

Retirement Calculators do much more than simply add up the money that’s set aside for retirement over several years.

A properly managed retirement portfolio should grow exponentially over the years through the power of compound interest. But this is also offset by the negative effects that inflation will put on a retirement fund’s purchasing power as the years go by.

For example, NerdWallet’s Retirement Calculator makes the following assumptions:

  • A 5% rate of return once you hit retirement
  • An average inflation rate of 3%
  • A 2% annual salary increase

These figures are based on historical averages and do an adequate job of projecting the growth of a retirement fund.

A 5% rate of return is pretty conservative. If we factor in the average inflation rate of 3%, we end up with a Real Rate of Return of roughly 2%.

It’s important to keep in mind that this 5% rate of return is realized during the retirement period. By this time, there should be enough money in the retirement account to sustain one’s lifestyle for a couple of decades, and growth rates aren’t really as important.

Most financial experts estimate that a retiree will need around 70% to 80% of his or her pre-retirement income to maintain the same standard of living they enjoyed during their working years.

There’s also the “4% Rule” which states that if you withdraw 4% from your retirement savings during the first year, then withdraw the same amount with an additional adjustment for inflation after each subsequent year, you can make your savings last up to 30 years.

To calculate how much a retirement account will be worth in the future, we’ll need two equations.

First, we need to calculate how much the Future Value (FV) of the initial savings amount will be after factoring in compound interest:

Afterward, we need to calculate the Future Value (FV) of the additional money that’s set aside for retirement (assuming a series of regular payments):

Where:

  • P = Principal
  • i = Interest rate
  • n = Number of compounding periods per year
  • C = Cash flow per period

Adding up the resulting numbers will give us the total Future Value of the retirement account:

Most people invest more aggressively and target higher returns during the earning and saving phase in preparation for retirement. There’s also a good chance that an individual’s income will continue to increase as they get older and move up in their career. This means they’ll have more money to put toward their retirement savings — assuming that they continue to allow the same percentage of their income towards their retirement fund.

Why Should I Use a Retirement Calculator?

Retirement can mean different things to different people. Some may want to save aggressively early on to quickly build up their nest egg so they can retire early and live off their savings and investments. While others prefer a more balanced approach and put aside just enough so they won’t have to worry about money once they hit their golden years and leave the workforce.
