### Importance of time value of money

The level of detail of these costs should be commensurate with the level of project detail. LCCA can also be an effective tool for evaluation of existing building systems and replacing those systems. While the length of the study period is often a reflection of the intended life of a facility, the study period is usually shorter than the intended life of the facility. The residual value of a facility or building system is especially important when evaluating project alternatives that have different life expectancies. It is possible that one alternative might be more susceptible to damage than others. Maintenance costs are scheduled costs associated with the upkeep of the facility. Constant-Dollars Just as discount rates can be defined as either real or nominal, so too can costs. The first years deposit earns interest for 10 years, the second years deposit earns interest for 9 years, etc. Thus, all initial costs will be entered into the LCCA at their full value. Residual Value The fifth step in the completion of the LCCA of a project alternative is to define the residual value of the alternative. The investor's financial status remains the same over the years and there is no gain or loss. The determination of the present value of future costs is time dependent. The operating costs are annual costs, excluding maintenance and repair costs, involved in the operation of the facility. For example, bonds can be readily priced using these equations. The study period is the period of time over which ownership and operations expenses are to be evaluated.

What is the future value of this deposit after 5 years? Since most initial expenses occur at about the same time, initial expenses are considered to occur during the base year of the study period.

Present Value: the current value of a past or future sum of money as a function of an investor's time value of money Real Discount Rate: a discount rate that excludes the rate of inflation.

Maintenance costs are scheduled costs associated with the upkeep of the facility. One reason for this is inflation and another is possible earning capacity. Most replacement costs are one-time costs. An example of a maintenance cost is the cost of an annual roof inspection and caulking of the building's roof penetrations.

The fundamental code of finance maintains that, given money can generate interest, the value of a certain sum is more if you receive it sooner.

## Reasons for time value of money

What is the cost of this car today? The use of either discount rate in its corresponding present value calculation derives the same result. Electric Rates Base Charge: This is a monthly service charge. Repair costs are unanticipated expenditures that are required to prolong the life of a building system without replacing the system. Well, the reason being inflation constantly erodes the value of the money, and henceforth the purchasing power of the money. At some point it will fail and require replacement to keep the facility operational. All replacement costs are to be discounted to their present value prior to addition to the LCCA total. Operating costs that are not directly related to the building should usually be excluded from the LCCA. What is Time Value of Money — Definition There is no reason for any rational person to delay taking an amount owed to him or her.

TVM and Compounding Periods How often the invested amount compounds too has a huge impact on future value. All replacement costs are to be discounted to their present value prior to addition to the LCCA total.

LCCA can also be an effective tool for evaluation of existing building systems and replacing those systems.

A negative residual value indicates that there is value associated with the building at the end of the study period. Life Cycle Cost: a sum of all costs of creation and operation of a facility over a period of time. TVM and Compounding Periods 1. Repair costs are unanticipated expenditures that are required to prolong the life of a building system without replacing the system. This is the only cost category in a LCCA where a negative value, one that reduces cost, is acceptable. Initial costs are incurred at the beginning of the study period at Year 0, the base year. NIST defines present value as "the time-equivalent value of past, present or future cash flows as of the beginning of the base year. Likewise, when using the nominal discount rate in present value calculations, costs must be expressed in current-dollars. An example of a maintenance cost is the cost of an annual roof inspection and caulking of the building's roof penetrations. See compound interest for details on converting between different periodic interest rates. TVM can also be referred to as Discounted present value. They are: Initial Expenses First Costs Future Expenses operation, maintenance, repair, energy, replacement Initial Expenses are all costs incurred prior to occupation of the facility. More than financial principles, this is basic instinct.
