    The SharpeSoft Estimator, displaying an example of a trench calculation. Calculations: Most estimating programs have built-in calculations ranging from simple length, area, and volume calculations to complex industry-specific calculations, such as electrical calculations, utility trench calculations, and earthwork cut and fill calculations.

    This allowed electrical engineers to simplify calculations for inductance and capacitance in power transmission lines. [18] The Curta calculator was developed in 1948 and, although costly, became popular for its portability. This purely mechanical hand-held device could do addition, subtraction, multiplication and division.

  4. Cost estimate - Wikipedia

    en.wikipedia.org/wiki/Cost_estimate

    A cost estimate is often used to establish a budget as the cost constraint for a project or operation. In project management, project cost management is a major functional division. Cost estimating is one of three activities performed in project cost management. [3] In cost engineering, cost estimation is a basic activity. A cost engineering ...

    You can use a calculator or the simple interest formula for amortizing loans to get the exact difference. For example, a $20,000 loan with a 48-month term at 10 percent APR costs $4,350.

  9. Cost of electricity by source - Wikipedia

    en.wikipedia.org/wiki/Cost_of_electricity_by_source

    The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
