The rule of 72 is a simple and helpful math trick to help you calculate the number of years it will take to double your invested money. All it requires is a basic division problem that you can probably do in your head.
The equation is:
Number of years = 72 / compound annual interest rate
Time out—what's the compound annual interest rate? It's the annual rate of return on your investment, applied to the original principal and to the accumulated interest from previous periods. Compound interest is the engine that will boost your investment to its goal.
Here's an example:
You want to double your investment in a mutual fund that you estimate will return 8% annually. Plug the interest rate (as "8") into the equation:
# of years = 72 / 8
The answer is 9. This means that your money will double in 9 years with an average return of 8%.
The equation works in the other direction, too. If you want to calculate the interest rate needed to double your money in 12 years, you plug 12 into the left side of the equation:
12 = 72 / x
Divide 72 by 12 and the answer is 6. You'll need an annual return of 6% to double your money in 12 years.
The rule of 72 provides an estimate that is extremely close to the exact answer for rates under about 11%. A few percentage points above that, it's better to use 73; a few above that, 74; and so on.
The key to the equation and your returns is annually compounding interest. It works because the interest gained in the previous year grows your investment, boosting the return for the following year. The cycle continues to grow your investment, increasing returns proportionally.
In the first example above, it takes you 9 years to double your investment at an 8% average annual return rate. If your investment is $1,000, you will have $2,000 after 9 years with compounding interest.
Let's say that your investment really did earn 8% every year (an average return rate doesn't necessarily mean that this will happen, but that the end result will be the same as if it did). After 1 year, your investment has earned 8%, or $80.
Now, your investment is $1,080. You earn 8% the next year, too, but this time you're earning 8% on $1,080, not $1,000. So your 8% return for the second year equals $86.40. Your investment has grown to $1,166.40 in two years. This is compound interest in action.
Its effect is drastic. If you'd decided to withdraw the return each year and spend it, instead of letting it compound, your returns would be much different. You still earn $80 after one year, but you take it home and spend it. Your investment stays at $1,000 for the second year, so you earn another $80 that you take home and spend.
You earn the same $80 every year for the nine years it should have taken you to double your money and what is your total return? $80 * 9 = $720. That's $280 dollars less than you would've made with compounding interest. If your investment was $10,000, you would have lost $2,800.
That's a significant difference. The rule of 72 uses the compound annual return rate to help you estimate length of time and rates of return for you to double your money. It's a valuable tool to help you set investing goals that you can achieve.
As anyone who has ever sold a house will tell you, you must prioritize curb appeal. Before a potential buyer even considers looking inside your house, they notice the outside first. Does it attract the right kind of attention? Does it take away from the feel you're going for? If you plan to sell sometime soon, you must think about these things. Here are some landscaping options to increase your home's curb appeal, so you can get the best price on your home.
Extensive Plants and Greenery
A barren front yard won't get you the price you want on your home. So, invest in at least a little bit of greenery to keep the surrounding area from looking too dead. Shrubs and bushes tie the house to the lawn that precedes it, and flower beds bring a pop of color to an otherwise drab structure. You can also strategically plant some trees to improve the overall feel of your home's exterior.
As we mentioned, your lawn is one of the most prominent features of your home's exterior. A patchy, dried-up lawn will quickly drive your home's price way down. Some of the best landscaping options for your home's curb appeal involve improving your lawn for the next inhabitant. Overall fertilization, ground aeration, underbrush removal, proper mowing—all of these lawn care tasks contribute to a greener and more lively area that invites people to see your house, rather than stay away from it.
There's nothing like a broken and disheveled pathway to make someone think twice about buying a property. Just as you want the entryway in your house to be welcoming, so too should the pathway leading up to the house be inviting. The pathway from the street to your front door provides plenty of real estate to get creative with. You don't have to settle for a boring concrete pathway. Consider something more eye catching, like a cobblestone path or intermittent brick patterns, as a way to better welcome potential buyers.
Usable Outdoor Furniture
Landscaping doesn't just involve the ground you walk on; also included are the items you use as extras to the overall look. Outdoor furniture is one such extra that you don't necessarily need but can look quite attractive if done correctly. Staging is important with outdoor furniture. Old, broken-down pieces will only look like more work to the potential buyer. A few comfortable chairs, a bench, or a table with an umbrella really go a long way to improving your outdoor aesthetics.
A good tip for deciding on curb appeal items is to decide what you personally would want to see as a part of a welcoming home's exterior. You don't need to go overboard, but a little bit of forethought could net you quite a lot of extra cash in the sale.
Many people strive to support their community by donating their time or their money. When you find a meaningful cause, you might be quick to cut a donation check. Though it's admirable to be quick to act charitably, you should be wary of several common mistakes made when giving to charity. Being mindful of these mistakes and learning tips for making informed charitable choices can help you make the most out of your generous check.
Acting Quickly Out of Emotion
Mission statements are meant to be compelling. If you're an emotionally driven individual, it's natural to pull out your wallet at the sight of a sad puppy on TV or when informed about food insecurity over the phone. Unfortunately, not all charities are as effective or official as they may seem.
Take your passion for helping others one step further by making sure your chosen charity is legit. Speaking with a representative, reviewing their website and social media accounts, and looking at testaments online can give you a better idea of whether the organization is worth your donation.
Forgetting to Keep Record of the Donation
Don't forget that you can reap some financial perks from giving back! With the proper documentation of your donation, you can acquire a better tax deductible.
If you donate more than $12,400 as a single filer or $24,800 as one of two joint filers, you're eligible to deduct that amount from your taxes. So, when a charity asks if you'd like a receipt of donation, always answer yes.
Donating Unusable Materials
Most charities can utilize a monetary donation—it's the physical donations that usually cause some issues. Providing a local nonprofit with irrelevant materials or gifting them with unusable products are surprisingly common mistakes made when giving to charity.
Always check your intended charity's website for a list of things they do and do not accept. The majority of places will provide a guideline to donating or offer contact information to clarify any questions.
Strictly Giving at Year's End
As more and more people get into the holiday spirit at the end of the year, nonprofit organizations see an influx of donations. While it's great to spread holiday cheer via a monetary donation, it's important to keep that spirit going year-round.
With regular donations, charities can more effectively allocate their annual budget. Setting up an automatic monthly donation with the charity of your choosing can maximize your impact. You can account for a monthly donation by foregoing a costly coffee every once in a while.
Knowing how much you should spend on home maintenance each year is hard to figure out and may be preventing you from buying your first home. The types of costs you'll incur depend on the house you buy and its location. The one certainty is that you should start saving now. Read on to figure out how much to start setting aside based on the home you own.
The Age of Your House
Consider several factors when budgeting for home repairs. If you've purchased a new home, your house likely won't require as much maintenance for a few years. Homes built 20 or more years ago are likely to require more maintenance, including replacing and keeping your windows clean. Further, depending on your home's location, weather can cause additional strain over time, so you may need to budget for more repairs.
The One-Percent Rule
An easy way to budget for home repairs is to follow the one-percent rule. Set aside one percent of your home's purchase price each year to cover maintenance costs. For instance, if you paid $200,000 for your home, you would set aside $2,000 each year. This plan is not foolproof. If you bought your home for a good deal during a buyer's market, your home could require more repairs than you've budgeted for.
The Square-Foot Rule
Easy to calculate, you can also budget for home maintenance by saving one dollar for every square foot of your home. This pricing method is more consistent than pricing it by how much you paid because the rate relies on the objective size of your home. Unfortunately, it does not consider inflation for the area where you live, so make sure you also budget for increased taxes and labor costs if you live in or near a city.
The Mix and Match Method
Since there is no infallible rule for how much you should spend on home maintenance, you can combine both methods to get an idea for a budget. Average your results from the square-foot rule and the one-percent rule to arrive at a budget that works for you. You should also increase your savings by 10 percent for each risk factor that affects your home, such as weather and age.
Holding on to savings is easier in theory than practice. Once you know how much you should spend on home maintenance, you'll know what to aim for and be more prepared for an emergency. If you are having trouble securing funds for home repairs, consider taking out a home equity loan, borrowing money from friends or family, or applying for funds through a home repair program through your local government for low-income individuals.
