What Is the Equivalent yearly Cost (EAC)?

Equivalent yearly cost (EAC) is the yearly cost the owning, operating, and maintaining one asset over its whole life. Firms frequently use EAC for capital budgeting decisions, as it allows a company to to compare the cost-effectiveness of miscellaneous assets with unequal lifespans.

understanding the Equivalent yearly Cost (EAC)

Equivalent yearly cost (EAC) is provided for a selection of purposes, including capital budgeting. But it is supplied most regularly to analyze two or much more possible tasks with various lifespans, where expenses are the most relevant variable.

Other offers of EAC incorporate calculating the optimal life of an asset, identify if leasing or purchasing an legacy is the far better option, determining the magnitude of which maintenance costs will influence an asset, determining the necessary price savings to support purchasing a new asset, and determining the price of maintaining existing equipment.

The EAC calculation determinants in a discount price or the expense of capital. Price of capital is the required return important to make acapital budgeting project—such as structure a new factory—worthwhile. Cost of capital includes the expense of debt and also the price of equity and also is offered by companies internally to referee whether a resources project is worth the expenditure the resources.

Equivalent annual cost (EAC) is the yearly cost that owning, operating, and maintaining one asset over its entire life.EAC is frequently used by this firm for funding budgeting decisions, together it allows a firm to to compare the cost-effectiveness of various assets that have actually unequal lifespans.EAC permits managers to to compare the net existing values of different projects over various periods, come accurately identify the best option.

The Formula for the Equivalent annual Cost

EAC=AssetPrice×DiscountRate1−(1+DiscountRate)−nwhere:DiscountRate=Returnrequiredtomakeprojectworthwhilen=Numberofperiodseginaligned & extEAC = frac extAsset Price imes extDiscount Rate 1 - ( 1 + extDiscount Rate)^-n \ & extbfwhere: \ & extDiscount Rate = extReturn compelled to do project \ & extworthwhile \ &n = extNumber that periods \ endaligned​EAC=1−(1+DiscountRate)−nAssetPrice×DiscountRate​where:DiscountRate=Returnrequiredtomakeprojectworthwhilen=Numberofperiods​

just how to calculation the Equivalent annual Cost

Take the asset price or cost and also multiply the by the discount rate.In the denominator include 1 + the discount rate and also raise the result as an exponent to the variety of years for the project. Subtract the an outcome by 1 and also divide the numerator figure by the denominator.Many financial virtual calculators are accessible to calculate EAC.

example of the Equivalent annual Cost

As proclaimed earlier, EAC allows managers to to compare NPVs of different projects over various periods, to accurately identify the ideal option. Consider two alternate investments in machinery equipment:

An initial capital outlay that $105,000An supposed lifespan of three yearsAn yearly maintenance cost of $11,000
An initial resources outlay of $175,000An intended lifespan of 5 yearsAn yearly maintenance price of $8,500

Next, we calculate the EAC, which is same to the net existing value (NPV) split by the present value annuity variable or A(t,r), while taking right into account the price of capital or r, and also the variety of years in inquiry or t.

AnnuityFactor=1−1(1+r)trwhere:r=Costofcapitalt=Numberofperiodseginaligned & extAnnuity Factor = frac 1 - frac 1 ( 1 + r ) ^ t r \ & extbfwhere: \ &r = extCost the capital \ &t = extNumber that periods \ endaligned​AnnuityFactor=r1−(1+r)t1​​where:r=Costofcapitalt=Numberofperiods​

Using the formula above, the annuity aspect or A(t,r) of each project need to be calculated. These calculations would be as follows:

MachineA,A(t,r)=1−1(1+.05)3.05=2.72eginaligned & extMachine A, A(t, r) = frac 1 - frac 1 ( 1 + .05) ^ 3 .05 = 2.72 \ endaligned​MachineA,A(t,r)=.051−(1+.05)31​​=2.72​

MachineB,A(t,r)=1−1(1+.05)5.05=4.33eginaligned & extMachine B, A(t, r) = frac 1 - frac 1 ( 1 + .05) ^ 5 .05 = 4.33 \ endaligned​MachineB,A(t,r)=.051−(1+.05)51​​=4.33​

Next, the initial prices must be divided by the annuity variable or A(t,r) while adding in the annual maintenance cost. The calculation because that EAC is:

EACMachineA=$105,0002.72+$11,000=$49,557eginaligned & extEAC device A = frac $105,000 2.72 + $11,000 = $49,557 \ endaligned​EACMachineA=2.72$105,000​+$11,000=$49,557​

EACMachineB=$175,0004.33+$8,500=$48,921eginaligned & extEAC device B = frac $175,000 4.33 + $8,500 = $48,921 \ endaligned​EACMachineB=4.33$175,000​+$8,500=$48,921​

By standardizing the yearly cost, a manager in fee of a capital budgeting decision where expense is the only concern would select maker B since it has an EAC that is $636 lower than an equipment A.

The Difference in between the Equivalent yearly Cost and the Whole-life expense

Whole-life price is the complete expense that owning one asset over its entire life, from acquisition to disposal, as established byfinancial analysis. The is likewise known as a "life-cycle" cost, which has purchase and installation, design and also building costs, operating costs, maintenance, connected financing costs, depreciation, and also disposal costs.

Whole-life cost additionally takes into account details costs that are usually overlooked, such as those connected to eco-friendly and social affect factors.

The equivalent yearly cost (EAC) is the annual cost that owning, operating, and also maintaining one asset over its whole life while the totality life cost is the complete cost that the asset over its entire life.

limitations of utilizing the Equivalent annual Cost

A limitation through EAC, as with many resources budgeting decisions, is the the discount rate or expense of resources must be approximated for every project. Unfortunately, the forecast deserve to turn out to it is in inaccurate, or variables can change over the life of the project or life of the heritage that's be considered.
