Rule Of 25 Vs 4 Percent Rule
Another retirement planning rule that can make it easy to decide how much you need to retire is the Rule of 25.
The 4% rule recommends the maximum amount you should spend in relation to your current retirement savings balance.
With the Rule of 25, you multiply your estimated annual expenses to determine how big your nest egg should be.
Annual expenses x 25 = Total retirement portfolio value necessary
So, if your annual spending is $40,000, you need $1 million.
$40,000 x 25 = $1,000,000
Either financial rule can help you create your savings goals and indicate when you can afford retirement.
The Origin Of The 4% Rule
The rule originated with a 1994 article by William Bengen. The title of the paper was Determining Safe Withdrawal Rates Using Historical Data. Mr. Bengen used historical market data for 30-year rolling periods. He wanted to focus on how the severe market downturns of the 1930s and early 1970s impacted portfolio withdrawals. The study determined that the 4% withdrawal rate was a sustainable withdrawal percentage to maintain the income level over a 30 year period without depleting the portfolio.
A study by three professors from Trinity University in San Antonio, TX, updated the Bengen study in 1998. For the most part, the Trinity Study affirmed Mr. Bergen’s previous work. Researchers often call the study the 4% rule.
Both studies assume the percentage that’s withdrawn each year adjusts for inflation. Both studies show the strategy offers the best chance for an individual not to outlive their money.
Initially, the assumption was for an investment allocation of 50% in the S & P 500 and 50% in intermediate-term government bonds. He also tests stock allocations of 25%, 50%, 75%, and 100%. As you would expect, the larger stock allocations offer better longevity. The results come from the historical past market returns from 1925 to 1994.
The Trinity study recently got updated. You can read about it in this article by Wade Pfau, one of the premier experts on retirement planning.
Beginning In Year 2 Of Retirement Adjust The Prior Years Spending By The Rate Of Inflation
Its the second year that trips some folks up. The way you calculate all the years in retirement after year one is different. Beginning in year two, you do not use 4%. Instead, you take the amount of money you were able to spend the prior year and adjust it for inflation.
So in our hypothetical we spent $40,000 in year one of retirement. Lets assume inflation is 2%. In year two, we could spend $40,800. To calculate this number, we simply add 2% to the amount we were able to spend in the previous year. Two percent of $40,000 is $800. Added to our first year spending brings us to $40,800. The following year well increase $40,800 by the rate of inflation .

Advantages And Disadvantages Of The Four Percent Rule
While following the Four Percent Rule can make it more likely that your retirement savings will last the remainder of your life, it doesnt guarantee it. The rule is based on the past performance of the markets, so it doesn’t necessarily predict the future. What was considered a safe investment strategy in the past may not be a safe investment strategy in the future if market conditions change.
There are several scenarios in which the Four Percent Rule might not work for a retiree. A severe or protracted market downturn can erode the value of a high-risk investment vehicle much faster than it can a typical retirement portfolio.
Furthermore, the Four Percent Rule does not work unless a retiree remains loyal to it year in and year out. Violating the rule one year to splurge on a major purchase can have severe consequences down the road, as this reduces the principal, which directly impacts the compound interest that the retiree depends on for sustainability.
However, there are obvious benefits to the Four Percent Rule. It is simple to follow and provides for predictable, steady income. And, if it is successful, the Four Percent Rule will protect you from running short of funds in retirement.

Retirement Withdrawal Calculator Insights
There are two sides to the retirement planning equation saving and spending.
The asset accumulation phase leads up to your retirement date followed by the decumulation phase where you spend down those assets to support living expenses in retirement.
The truth is retirement income planning is one of the most complex and controversial aspects in financial planning. There are so many different models with each being dependent on assumptions chosen, portfolio assets, and risk tolerance.
- For example, dividend growth stocks have the potential to provide inflation adjusting income and capital growth, but they will also deliver increased volatility and risk of permanent loss in the wrong market conditions.
- A bond portfolio will provide stable, reliable income, but the income and assets will erode in purchasing power over time due to inflation.
- Traditional fixed annuities can provide a floor of reliable income that you can never outlive and a potentially higher safe withdrawal rate than bonds or stocks alone can provide, but the downside is loss of liquidity and a potentially smaller estate for your heirs.
In short, there is no sure-fire solution to retirement income planning that solves all problems. Each strategy results in tradeoffs between risk and required income goals. No single retirement withdrawal calculator can model all spending alternatives effectively.

Should You Use The 4% Rule
The 4% rule is a good guideline to help you as you plan your retirement savings. It might not be the best system, though, to follow once you retire.
Your plan should be based on many factors, such as:
- All of your other expected sources of income
- What types of investments you have
- How long you can expect to live
- What your tax rate might be after you retire
Your needs will also change from year to year once you stop working. Some years, you may need to withdraw more due to travel or unexpected medical bills. Other years, you might need less.
The 4% rule also becomes useless once you reach age 72, which is when you have to start taking withdrawals from your IRAs, known as “required minimum distributions,” or RMDs. These RMDs are based on a formula, which will require you to take more than 4% of your remaining account value as you get older. Each year as you get older, you must take out a higher amount. Granted, you dont have to spend the money, but you do have to withdraw it from the IRA, which means paying taxes on it.

Calculate What Your Savings Will Cover When You’re Retired
Understanding what you expect retirement to look like will help determine how much you’ll need in order to fund that lifestyle. If you plan to travel the world in luxury, your budget will be a bit different than someone who just wants to birdwatch from the backyard each morning.
In retirement, your savings will cover many of the same expenses that you had prior to retirement. These include, to name a few:
- Food
- Insurance
- Travel
If you don’t plan for any of these categories to change much from pre- to post-retirement, then you should have a good idea of your budget. However, if you have big plans for your retirement years, it’ll be important to determine how much your new standard of living will cost.
Quick tip: More and more seniors are going into retirement with lingering home mortgage expenses. If your home will not be paid off by retirement, be sure to account for this monthly expense in your savings.
Also be sure to account for unexpected expenses that could come up, such as medical care for you and your spouse, or even helping a child or grandchild financially.
Next, consider where you plan to live. You may want to downsize, or you might plan to buy your dream retirement home. Either way, be sure to factor in all those costs.
Note: The average age of retirement has risen steadily in recent years, from 62 to 64 for men and from 60 to 62 for women.
The Assumed Rate Of Return
The assumed rate of return is where things get tricky. Performances in the study may not reflect the returns in the future.
One major factor is that bond yields have been substantially lower in recent years than in the past. The current ten-year Treasury rate on July 28, 2020, was 0.59%. The rate is unlikely to go back to the levels of the late 1970s and 1980s. Some of you remember those days. Interest rates and inflation were in double digits for much of the decade. That skews the return number considerably.
Back then, people retiring could live off the bonds and fixed income investments like CDs. When you could take out double-digit incomes, it made retirement planning more manageable.
The bigger problem in those years was that inflation was just as high. So, the buying power of the money diminished due to much higher inflation.
Since the financial crisis of 2007- early 2009, interest rates have been near zero. That means replicating the kinds of returns needed you’d have to have more money invested in stocks. Many people want to reduce the amount in equities at retirement to reduce the risk of their investments. However, to maintain buying power and generate the returns necessary to make their money last, many retirees have more money in stocks than they want.
Dividend yields on the S & P 500 are around2% or so. That’s well below the 4 percent SWR. The days of living off the interest are gone and likely not coming back any time soon.

How Much Money Do I Need To Retire
In days gone past, the three-legged stool for retirement meant counting on pensions, Social Security and savings. Those who depend on that stool nowadays will fall hard, because the pension leg is either gone or going away. The Federal Reserve reports that only 22% have pensions to rely on in retirement. Thats less than one-fourth of the population.
The maximum Social Security benefit in 2020 at full retirement age is $3,011. But, the average Social Security benefit in January of 2020 was just $1,503. Thats $18,036 per year. Its not hard to see that wont go far.

Break Down How Much You Should Be Saving Each Year

Now that you have an idea of how much you’ll need, you can begin calculating how much you should be setting aside annually.
One simple way to determine your savings goals is to aim for a multiple of your current annual earnings. While the actual amount varies according to your projected retirement costs and even the specific investments you choose for your retirement portfolio, these serve as a rough target and give you a better sense of where you stand.
According to Fidelity, here’s how much you should have saved up each decade in order to meet your retirement goals:
10+ times |
To reach these targets, many financial experts suggest a dedicated savings rate of 15% to 20% per year. However, you may need to save even more, depending on what retirement will look like for you, what sort of financial obligations you expect to have in retirement, and your current assets.
The sooner you start saving, the easier it will be to compound your savings and reach your goals by the time retirement arrives.

Retirement Withdrawal Strategies: How To Withdraw Money From A Retirement Account
Since Social Security benefits are not always sufficient to keep up the living standard you are used to during your post-income-earning stage of life, you may decide to obtain a retirement account to provide additional income supplements. If you happen to put aside such savings or consider opening an investment account devoted to your retirement, it is essential to ensure that your money will last long enough. A smartly chosen early retirement withdrawal strategy can support you in such a situation. Let’s explore what are the retirement plan withdrawal possibilities.
- The 4 percent rule
The 4 percent rule withdrawal strategy suggests that you should withdraw 4 percent of your investment account balance in your first year of retirement. And from then on you should increase the amount to keep pace withinflation.
For example, if you have 300,000 dollars in your account, you would withdraw 12,000 dollars in your first year of retirement. If there is 2 percent of inflation , you will withdraw 12,240 dollars in the following year.
The advantage of the 4 percent rule is that it’s a simple approach, and your buying power keeps up with inflation.
- Fixed-dollar withdrawals
Fixed-dollar withdrawals involve taking the same amount of money out of your retirement account every year for a set period. For example, you may decide to withdraw 1,000 dollars every month for the first five years of retirement and then re-evaluating.
- Fixed-percentage withdrawals
- Systematic withdrawals
