  2. Rate equation - Wikipedia

    en.wikipedia.org/wiki/Rate_equation

    The tentative rate equation determined by the method of initial rates is therefore normally verified by comparing the concentrations measured over a longer time (several half-lives) with the integrated form of the rate equation; this assumes that the reaction goes to completion. For example, the integrated rate law for a first-order reaction is

  3. Internal rate of return - Wikipedia

    en.wikipedia.org/wiki/Internal_rate_of_return

    Internal rate of return (IRR) is a method of calculating an investment's rate of return.The term internal refers to the fact that the calculation excludes external factors, such as the risk-free rate, inflation, the cost of capital, or financial risk.

  4. Rate of return - Wikipedia

    en.wikipedia.org/wiki/Rate_of_return

    (The initial value is treated as an inflow, and the final value as an outflow.) When the internal rate of return is greater than the cost of capital, (which is also referred to as the required rate of return), the investment adds value, i.e. the net present value of cash flows, discounted at the cost of capital, is greater than zero. Otherwise ...

  5. Enzyme kinetics - Wikipedia

    en.wikipedia.org/wiki/Enzyme_kinetics

    If the initial rate of the reaction is measured over a range of substrate concentrations (denoted as [S]), the initial reaction rate increases as [S] increases, as shown on the right. However, as [S] gets higher, the enzyme becomes saturated with substrate and the initial rate reaches V max, the enzyme's maximum rate.

  6. Return on investment - Wikipedia

    en.wikipedia.org/wiki/Return_on_investment

    Internal rate of return; Marketing plan; Price–earnings ratio; Rate of profit; Rate of return (RoR), also known as 'rate of profit' or sometimes just 'return', is the ratio of money gained or lost (whether realized or unrealized) on an investment relative to the amount of money invested; Return on assets (RoA) Return on brand (ROB)

    An adjustable-rate mortgage, or ARM, is a home loan that has an initial, low fixed-rate period of several years. After that, for the remainder of the loan term, the interest rate resets at regular ...

  8. Compound interest - Wikipedia

    en.wikipedia.org/wiki/Compound_interest

    The effective annual rate is the total accumulated interest that would be payable up to the end of one year, divided by the principal sum. These rates are usually the annualised compound interest rate alongside charges other than interest, such as taxes and other fees.

    With a fixed-rate product, such as a personal loan or savings account, the interest rate you sign up for is the interest rate you’ll either pay or earn for the life of the product.
