A financial calculator or business calculator is an electronic calculator that performs financial functions commonly needed in business and commerce communities [1] (simple interest, compound interest, cash flow, amortization, conversion, cost/sell/margin, depreciation etc.).
That is an extreme case; in general the formula will understate the total cost of a basket of goods (or of any subset of that basket) unless their prices all change at the same rate. Also, as the index is unweighted, large price changes in selected constituents can transmit to the index to an extent not representing their importance in the ...
1979, VisiCalc for Apple II with 32K RAM, the first widely used normal spreadsheet with A1 notation etc. 1980, SuperCalc for CP/M-80 operating system, included with early Osborne computers. 1982, ZX81 Memocalc, for low cost ~$100 personal computer with 16K RAM expansion, launched by Memotech in April 1982.
A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate. A cost ...
A handwritten spreadsheet. A basic estimating spreadsheet. Cost estimators used columnar sheets of paper to organize the take-off and the estimate itself into rows of items and columns containing the description, quantity and the pricing components. Some of these were similar to accounting ledger paper.
LibreOffice Calc is the spreadsheet component of the LibreOffice software package. [7] [8]After forking from OpenOffice.org in 2010, LibreOffice Calc underwent a massive re-work of external reference handling to fix many defects in formula calculations involving external references, and to boost data caching performance, especially when referencing large data ranges.

To derive MC the first derivative of the total cost function is taken. For example, assume cost, C, equals 420 + 60Q + Q 2. then MC = 60 + 2Q. [11] Equating MR to MC and solving for Q gives Q = 20. So 20 is the profit-maximizing quantity: to find the profit-maximizing price simply plug the value of Q into the inverse demand equation and solve ...
