Absolute Breadth Index (ABI) Calculator
This calculator will compute the absolute breadth index (ABI) for a stock market, given the number of advancing stocks in the market and the number of declining stocks in the market.
  • The absolute breadth index is a measure of the amount of activity or change in a stock market. Larger ABI values indicate that the stock market is undergoing substantial change, while smaller values indicate that the stock market is relatively stable.
Alpha Value Calculator
This calculator will compute the alpha value (also known as the Average Differential Return) for a market security, given the security's beta value and market return rate, and the risk-free rate of return.
  • Alpha values greater than zero indicate that an investment has produced larger returns than expected for its risk level, while values less than zero indicate that the investment has earned smaller returns than expected for its risk level.
Arbitrage Profit Calculator for Currency Exchanges
This calculator will compute the profit associated with an arbitrage transaction for a currency exchange, given the amount borrowed of currency A, the borrowing rate for currency A, the lending rate for currency B, the duration of the transaction in days, and the exchange rate between currencies A and B.
  • Arbitragers take advantage of interest rate differences between two currencies in order to generate profits from borrowed funds.
Arbitrage Profit Calculator for Stocks or Commodities
This calculator will compute the profit associated with an arbitrage transaction for a stock or commodity, given the higher price of the stock or commodity on one exchange, the lower price of the stock or commodity on another exchange, and the number of shares or units involved in the transaction.
  • Arbitragers take advantage of inter-market inefficiencies by simultaneously buying and selling a stock or commodity on different exchanges in order to produce risk-free profits.
Beta Value Calculator
This calculator will compute the beta value for an investment, given the covariance between the investment's returns and those of the market, and the variance of the market returns.
  • An investment's beta value describes the relationship between the investment's returns and those of the market. Positive beta values indicate that an investment's returns tend to move in concert with the market, while negative values indicate that an investment's returns tend to move in an opposite direction from the market.
Black-Scholes Calculator for the Price of a Put Option
This calculator uses the Black-Scholes formula to compute the price of a put option, given the option's time to maturity and strike price, the volatility and spot price of the underlying stock, and the risk-free rate of return.
  • The Black-Scholes option-pricing model can be used to compute the price of a put option in light of current market conditions.
Black-Scholes Calculator for the Value of a Call Option
This calculator uses the Black-Scholes formula to compute the value of a call option, given the option's time to maturity and strike price, the volatility and spot price of the underlying stock, and the risk-free rate of return.
  • The Black-Scholes option-pricing model is useful for computing the present value of a stock option in light of current market conditions.
Bond Valuation Calculator
This calculator will compute the present value of a bond, given the bond's annual interest payment, value at maturity, and years to maturity, and the investor's required rate of return.
  • The present value of a bond can be compared to the bond's current market price in order to help an investor decide whether the bond should be purchased.
Bond Yield to Maturity (YTM) Calculator
This calculator will compute the yield to maturity (YTM) for a bond, given the bond's annual interest payment, current market price, value at maturity, and years to maturity.
  • The yield to maturity for a bond is the internal rate of return that the bond holder will earn if a bond is bought at the current market price and is held to maturity.
Book Value Per Share Calculator for Common Stock
This calculator will compute the book value per share for a company's common stock, given the total shareholders' equity, the liquidation value of any preferred stock, the amount of preferred dividends in arrears, and the number of shares of common stock outstanding.
  • The book value per share of common stock represents the right that each share of common stock has to a company's net assets.
Book Value Per Share Calculator for Preferred Stock
This calculator will compute the book value per share for a company's preferred stock, given the liquidation value of the preferred stock, the amount of preferred dividends in arrears, and the number of shares of preferred stock outstanding.
  • The book value per share of preferred stock represents the amount of shareholders' equity that is clearly assignable to preferred stock on a per share basis.
Capitalization Rate Calculator
This calculator will compute the capitalization rate for a real estate investment, given the property's net operating income and its purchase price.
  • The capitalization rate (also known as the income yield) is a measure of the annual rate of return for a real estate investment property.
Current Yield of a Bond (Simple Yield) Calculator
This calculator will compute the current yield of a bond (i.e., the simple yield of a bond), given the current market price of the bond and the bond's annual coupon interest payment.
  • The current yield of a bond will vary over time in conjunction with changes in the bond's market price.
Expected Stock Performance Calculator
This calculator uses the capital asset pricing model (CAPM) to compute the expected rate of return for a stock, given the stock's beta value, the market rate of return, and the risk-free rate of return.
  • The expected rate of return for a stock is based on the stock's level of risk in light of current market conditions.
Gross Income Multiplier (GIM) Calculator
This calculator will compute the gross income multiplier (GIM) for a real estate investment property, given the annual amount of gross rental income produced by the property and the property's asking price.
  • The gross income multiplier (also known as the gross rent multiplier) is a method of evaluating the value or potential value of an income-producing property. In general, properties with smaller GIM values are better investments than those with larger GIM values.
Present Value Interest Factor (PVIF) Calculator
This calculator will compute a present value interest factor (PVIF), given the periodic interest rate and the number of periods.
  • The PVIF is commonly used to simplify the process of calculating present values.
Present Value Interest Factor of an Annuity (PVIFA) Calculator
This calculator will compute the present value interest factor of an annuity (PVIFA), given the periodic interest rate and the number of periods.
  • The PVIFA is commonly used to calculate the present value of a series of annuities.
Stock Risk Premium Calculator
This calculator uses the capital asset pricing model (CAPM) to compute the risk premium for a stock, given the stock's beta value, the market rate of return, and the risk-free rate of return.
  • The risk premium for a stock is the additional rate of return over and above the risk-free rate that an investor can expect to receive in exchange for assuming a higher level of risk.
Yield on a Perpetual Bond Calculator
This calculator will compute the yield on a perpetual bond, given the bond's current market price and the annual interest payment for the bond.
  • Perpetual bonds have no date of maturity. Therefore the face value of a perpetual bond will ostensibly never be repaid.
