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.
Afghan women
Over the past month, both Haiti and Afghanistan have been pummeled by tragic disasters that left devastation in their wake.
In Haiti, a 7.2 magnitude earthquake erupted, leading over to 2,189 deaths and counting. A few hours later, in Afghanistan, Kabul fell to the Taliban just after U.S. troops had pulled out after 20 years of war.
In many ways, these disasters are both chillingly connected to US interference. The United States invaded Haiti in 1915, ostensibly promising to restore order after a presidential assassination but really intending to preserve the route to the Panama Canal and to defend US creditors, among other reasons.
But the US forces soon realized that they were not able to control the country alone, and so formed an army of Haitian enlistees, powered by US air power and intended to quell Haitian insurrection against US controls. Then, in 1934, the US pulled out on its own, disappointed with how slow progress was going. Haiti's institutions were never really able to rebuild themselves, leaving them immensely vulnerable to natural disasters.
Something similar happened in Afghanistan, where the US sent troops and supported an insurgent Afghan army – only to pull out, abandoning the country they left in ruins, with many Afghans supporting the Taliban.
In both cases, defense contractors benefited by far the most from the conflict, making billions in profits while civilians faced fallout and devastation. While the conflicts and circumstances are extremely different and while the US is obviously not solely to blame for either crisis, it's hard not to see the US-based roots of these disasters.
Today, in Haiti and Afghanistan, civilians are facing unimaginable tragedy.
Here are charities offering support in Afghanistan:
1. The International Rescue Committee is looking to raise $10 million to deliver aid directly to Afghanistan
2. CARE is matching donations for an Afghanistan relief fund. They are providing food, shelter, and water to families in need; a donation of $89.50 covers 1 family's emergency needs for a month.
3. Women for Women International is matching donations up to 500,000 for Afghan women, who will be facing unimaginable horrors under Taliban control.
4. AfghanAid offers support for people living in remote regions of Afghanistan.
5. VitalVoices supports female leaders and changemakers and survivors of gender-based violence around the world.
Here are charities offering support in Haiti:
1. Partners in Health has been working with Haiti for a long time, and they work with the Department of Health rather than around them, which is extremely important in a charity.
2. Health Equity International helps run Saint Boniface Hospital, a hospital in Haiti close to the earthquake's epicenter.
3. SOIL is an organization based Haiti, "a local organization with a track record of supporting after natural disasters." They are distributing hygiene kits and provisions on the ground to hospitals and to victims of the earthquake.
4. Hope for Haiti has been working in emergency response in Haiti for three decades, and their team is comprised of people who live and work in Haiti. They focus on supporting children and people in need across Haiti.
When the new Tiffany's campaign was unveiled, reactions were mixed.
Tiffany's, the iconic jewelry brand which does not (despite what some might be misled to believe) in fact serve breakfast, featured Jay Z, Beyoncé, and a rare Basquiat painting in their recent campaign.
The aesthetics were undeniably luxe and historic. The campaign showcased the rarely-seen Basquiat painting Equals Pi (1982), which the brand acquired for the background's proximity to its distinctive Tiffany blue. Also notably historic is that Beyoncé was the first Black woman to wear the 128.54 carat Tiffany Diamond.
Before Beyoncé, the only other stars to wear the yellow diamond were Mary Whitehouse, wife of American diplomat Edwin Sheldon Whitehouse, Hollywood icon Audrey Hepburn, and singer Lady Gaga.
"Beyoncé and Jay-Z are the epitome of the modern love story …. Love is the diamond that the jewelry and art decorate," said the press release accompanying the campaign.
The campaign, titled "About Love," is stunning and has both classic and contemporary references. The image of the couple posing in front of high art recalled the iconic stills from their "APESHIT" music video, for which they famously rented out the Louvre and posed in front of the Mona Lisa.

Their "APESHIT" photo made a giant cultural impact for its juxtaposition of Western beauty and Blackness. Tiffany's campaign seemed to have similar goals — showcasing Beyoncé and Jay Z as the peak of luxury, this time juxtaposing the Basquiat and the Tiffany diamond.
As a Black couple, their appearance in such a luxury campaign was a big move for representation, but in a post 2020 landscape, there was an outcry of criticism.
Despite the aesthetic beauty of the image, the high capitalist undertones didn't sit right with some on the internet — largely younger demographics. Though this campaign was an effort by Tiffany's to appeal to younger audiences and make the brand feel more relevant, Twitter's verdict was clear: a blood diamond wasn't the way to go.
The diamond, which was mined in South Africa in 1877, comes from origins laden in the implications of colonialism. The practice of mining in South Africa at the time was exploitative and destructive, eschewing the livelihoods and safety of African miners and their communities for... what? Money? So Tiffany could try to sell us some dream of affluence using Black celebrities as to "Blackwash" the history behind their treasured piece?
The Washington Post also had some choice words, saying: "Its campaign does not celebrate Black liberation — it elevates a painful symbol of colonialism. It presents an ostentatious display of wealth as a sign of progress in an age when Black Americans possess just 4 percent of the United States's total household wealth. If Black success is defined by being paid to wear White people's large colonial diamonds, then we are truly still in the sunken place."
Alongside the campaign, Tiffany & Co have promised to donate $2 million to HBCUs to fund scholarships and internships. But this measly amount (considering the multi-billion dollar net worth behind LVMH) is not enough to cover up that, despite their performative efforts to promote "diversity," Tiffany's is entrenched in a colonial history that neither beauty nor Beyonce can make us ignore.
While Black representation has been increasing over the past few years, the question of how we are represented is starting to be considered with more nuance. And as we examine the structures of wealth and hierarchical values, many people are starting to ask whether these should be the standards we aspire to anymore.
Jay Z and Beyoncé have come under fire before for their promotion of Black Capitalist values — which the kids don't seem to want. Jay Z especially seems invested in the trappings of traditional (read: white) success and wealth. His cannabis line recently unveiled a campaign based on the work Slim Aarons — which was famously focused on "attractive people doing attractive things in attractive places" — and its unashamed opulence raised some eyebrows.
Images like this aren't as revolutionary as they once might have been since they reinforce the status quo and tell marginalized people to reach for the same luxuries and lifestyles deemed aspirational by the people who have oppressed them.
Anti-capitalist theory has been around as long as capitalism has, but younger generations are more likely to question the status quo — even when it comes packed with Basquiat and Beyoncé.
The conversation about the Tiffany campaign is indicative of how Gen Z thinks differently about money and what it means to them. They are less likely to be seduced by the luster of the aspirational, and more receptive to relatability.
This is why apps like Cleo have been on the rise. Cleo is a budgeting and personal finance app which makes money feel less inaccessible and makes engaging in personal finance relatable and easy.
No more does financial literacy seem restricted to the pretentious or the elite — we get it, finance bros; you love capitalism. With Cleo, understanding your money is something that can align users with their values.
And those values don't look like blood diamonds or corporate pandering.

Road trips can be a lot of fun — but they can also drain your wallet quickly if you aren't careful.
From high gas costs and park admission fares to lodging and the price of eating out every night, the expenses can add up quickly. But at the same time, it's very possible to do road trips cheaply and efficiently. Without the headache of worrying about how much money you're leaking, you can enjoy the open road a whole lot more. Here's how to save money on a road trip.
1. Prepare Your Budget, Route, and Packing List in Advance
If you want to save money on a road trip, be sure you're ready to go. Try to count up all your expenses before you hit the road and create a budget. It's also a good idea to plan your route in advance so you don't end up taking unnecessary, gas-guzzling detours. And finally, be sure to pack in advance so you don't find yourself having to buy tons of things you forgot along the way.
2. Book Cheap Accommodations — Or Try Camping
All those motel rooms can add up surprisingly quick, but camping is often cheap or free, and it's a great way to get intimate with the place you're visiting. You can check the Bureau of Land Management's website for free campsites. Freecampsite.com also provides great information on If you don't have a tent or don't want to camp every night, try booking cheap Airbnbs or booking hotels in advance, making sure to compare prices.

If you're planning on sleeping in your car, a few tips: WalMart allows all-night parking, as do many 24-hour gyms. (Buying a membership to Planet Fitness or something like it also gives you a great place to stop, shower, and recharge while on the road).
3. Bring Food From Home
Don't go on a road trip expecting to subsist on fast food alone. You'll wind up feeling like shit, and it'll drain your pocketbook stunningly quickly. Instead, be sure to bring food from home. Consider buying a gas stove and a coffee pot for easy on-the-go meals, and make sure you bring substantial snacks to satiate midday or late night cravings so you can avoid getting those late night Mickey D's expeditions.
Try bringing your own cooler, filling it with easy stuff for breakfast and lunch — some bread and peanut butter and jelly will go a long way. Bring your own utensils, plates, and napkins, and avoid buying bottled water by packing some big water jugs and a reusable water bottle. Alternatively, try staying at hotels or Airbnbs with kitchens so you can cook there.
4. Avoid Tolls
Apps like Google Maps and Waze point out toll locations, so be sure to avoid those to save those pennies. (If it takes you too far off route, you might have to bite the bullet and drive across that expensive bridge).
You can also save on parking fees by using sites like Parkopedia.

5. Save on Gas
Gas can get pricy incredibly fast, so be sure that you're stopping at cheap gas stations. Free apps like GasBuddy help you find the most affordable gas prices in the area. Also, try going the speed limit on the highways — anything faster will burn through your tank. Be sure that you don't wait till you arrive at touristy locations or big cities to fill up.
6. Get a National Park Pass
All those parks can get really expensive really fast. If you're planning on visiting three or more parks, it's a great idea to get an America the Beautiful National Parks Pass. For $80 you can get into every National Park for one year.
