Calculate your capital gains tax bill

Capital assets include investments from stocks to fine jewelry

Capital assets can be classified as property owned and used for personal or investment reasons. If a capital asset grows in value and the holder decides to sell it, their “capital gains” would be roughly the difference between the original purchase price and the amount of money they sold the asset for.

Some policymakers take issue with long-term capital gains being taxed at a preferential rate compared to income from paid work

The concept of taxing unrealized capital gains—when an asset’s value increases but has yet to be sold—has been increasingly debated. Other policymakers in recent years have supported lowering the highest long-term capital gains tax rate and are generally opposed to levying taxes on unrealized capital gains.

How to calculate your net worth

Watch how the S&P 500 is actually calculated

After accounting for each company's float-adjusted market capitalization (a metric that combines the price of a company's stock, the total number of shares, and the stock's float, which means how many shares are actually available), the S&P 500 formula uses a divisor to create the index number. However, what the divisor is and what it represents are secrets.

Investors need a 'margin account' to short sell stock

Margin accounts are leveraged accounts through brokerage firms that allow investors to make trades without the full amount of capital on hand. Similar to a secured loan, margin accounts often require some form of collateral and typically have a cap on how much investors can borrow. However, trading with a margin account is much riskier than a traditional investment account. Fees and charged interest are due on margin accounts, regardless of trade performance, meaning it's possible for investors to lose more money than just their initial investment.

Compounding, explained

During conversations about personal finance, the term "compounding" gets thrown around—but not everyone understands how compound interest and compound returns work. Broadly speaking, compounding is what happens when you not only earn returns or interest on your original investment, but also on the accumulated returns or interest you receive over time. This article explains how both of these processes function, and what compounding could mean for your wallet.

Contract prices on prediction markets are generally interpreted as implied probabilities

For example, if a contract trading is at $0.65, that could be read as the market assigning a 65% probability to that event occurring. The most common format for prediction markets is winner-take-all: The contract settles at $1 if the event occurs, or $0 if it doesn't.

The price of crude oil accounts for roughly half of the price displayed at the gas pump

While the price of crude oil has the largest impact on the price of gas, the cost of refinement, taxes, and distribution jointly make up nearly half of how gas is priced. Because of the many factors that influence the price of gas, eliminating taxes during expensive periods might not effectively lower prices.

Brand valuations give companies an idea of how valuable assets, like logos, are to the company and can help determine how much money branding departments should receive. Typically, brand valuations are a compilation of brand awareness metrics, like a consumer's willingness to pay, the value of a trademark, and the company's market position.
