  2. Break-even - Wikipedia

    en.wikipedia.org/wiki/Break-even

    Break-even (or break even), often abbreviated as B/E in finance (sometimes called point of equilibrium), is the point of balance making neither a profit nor a loss. It involves a situation when a business makes just enough revenue to cover its total costs. [1] Any number below the break-even point constitutes a loss while any number above it ...

  3. Energy return on investment - Wikipedia

    en.wikipedia.org/wiki/Energy_return_on_investment

    The issue is still subject of numerous studies, and prompting academic argument. That's mainly because the "energy invested" critically depends on technology, methodology, and system boundary assumptions, resulting in a range from a maximum of 2000 kWh/m 2 of module area down to a minimum of 300 kWh/m 2 with a median value of 585 kWh/m 2 according to a meta-study from 2013.

  4. 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 ...

  5. Payback period - Wikipedia

    en.wikipedia.org/wiki/Payback_period

    Payback period. Payback period in capital budgeting refers to the time required to recoup the funds expended in an investment, or to reach the break-even point. [1] For example, a $1000 investment made at the start of year 1 which returned $500 at the end of year 1 and year 2 respectively would have a two-year payback period.

    The Break-Even Point. The break-even point (BEP) in economics, business —and specifically cost accounting —is the point at which total cost and total revenue are equal, i.e. "even". In layman's terms, after all costs are paid for there is neither profit nor loss. [1][2] In economics specifically, the term has a broader definition; even if ...

    en.wikipedia.org/wiki/Discounted_payback_period

    Discounted payback period. The discounted payback period (DPB) is the amount of time that it takes (in years) for the initial cost of a project to equal to the discounted value of expected cash flows, or the time it takes to break even from an investment. [1] It is the period in which the cumulative net present value of a project equals zero.

  8. Time value of money - Wikipedia

    en.wikipedia.org/wiki/Time_value_of_money

    Time value of money. The present value of $1,000, 100 years into the future. Curves represent constant discount rates of 2%, 3%, 5%, and 7%. The time value of money refers to the fact that there is normally a greater benefit to receiving a sum of money now rather than an identical sum later. It may be seen as an implication of the later ...

  9. Net present value - Wikipedia

    en.wikipedia.org/wiki/Net_present_value

    The net present value (NPV) or net present worth (NPW) [1] is a way of measuring the value of an asset that has cashflow by adding up the present value of all the future cash flows that asset will generate. The present value of a cash flow depends on the interval of time between now and the cash flow because of the Time value of money (which ...
