Financial & Math Calculators
- Option Pricing Calculators
Calculators for option pricing, which includes currency, equity and futures options. Features the usual Black-Scholes model, as well as several other models for option pricing.
- Dividend Discount Model
This provides the Dividend Discount Model used to value publicly traded stocks. The model works by "the present value of the future dividends that a company is expected to pay its shareholders".
- Stock Market Valuation
Applies a stock market valuation model to determine a fair value of the S&P 500, using a traditional corporate earnings discount model adjusted to account for the equity risk premium.
- Taylor Rule Calculator
The Taylor Rule - a rule for calculating an optimal central bank interest rate - is calculated here for the two parameters of the natural rate of unemployment and an inflation target.
- Differential Equations Calculator
This applet solves differential equations using one of several numerical methods; including, inter alia, Euler, 4th order Runge-Kutta & Adaptive Runge-Kutta. A friendlier alternative is available here.
- Calculus Calculator
Integrates or differentiates functions, with range limitations and a graphing option. The MathServ Calculus Toolkit performs many of the same functions, plus a couple more using other methods (such as Newton's).
- Tools for Integration
A list of operational tools for integration, from the basic Rieman sums and antiderivatives, to solids of revolutions and ordinary differential equations. A quicker integration tool is The Integrator.
- Matrix Algebra Solver
This solver performs basic operations for matrices. It also calculates determinants. The Gaussian Eliminator Tool solves linear equations in a quick, fuss-free way.
- Bayes' Theorem Calculator
Has an introduction to the theorem plus a calculator for up to 5 hypotheses. A simpler, hypothesis-datum Bayesian Calculator is also useful.
- Multivariable Linear Regression
Multivariable linear regression, on a limit of 4 dependent variables. Another alternative, the Statistical Regression site is more difficult to use, but provides transformations.
