Unit of Production Method

  

Categories: Accounting

Usually, depreciation is calculated as a function of time. Use the nut-cracking machine in your peanut butter factory for a year, and it depreciates by a certain amount. The fact that you shut down the factory for six months after the elephant attack doesn't play into the equation. A year is a year.

The unit of production method uses a different standard. Instead of using fixed time intervals, it calculates depreciation in relation to usage. The amount of depreciation relates to how much an asset gets used. The more nuts you crack with the machine, the more it depreciates.

This method is often considered more accurate, since machines wear out from use, not just by getting older. Unlike your Uncle Wally, of course, who really hasn't left the couch in the last four decades, but looks like a reanimated mummy.

But, more accurate or not, this method can present a problem. It requires a more involved process. You have to actually count the number of nuts cracked to keep account of how much the machine is getting used. Or...you at least have to keep proper records about when its being used and what its workload looks like. It can become a pain.

That drawback leads a lot of companies to fall back on the simple time equation. It's just easier to track. As such, the units of production model often gets reserved for really expensive equipment...stuff where the rate of depreciation can make a serious impact on the books.

Finance a la shmoop what is double-declining balance sheet

00:05

depreciation kind of sounds like that strange-looking British double-decker [Buses in London]

00:10

bus right but it's not instead it's a structure or formula under which [Definition of a double declining balance sheet]

00:15

companies assess the depreciating value of an asset that you know loses value

00:21

it's basically the way they lose or track the loss of value in it that's [Guy talking on a London street]

00:25

different from normal depreciation like a tractor smelting Factory or the break [A bucket of molten metal being poured]

00:35

on to that one bar since 1992 we got to depreciate those well if Shmaterpiller

00:40

has a smelting Factory they paid a hundred million bucks to build which [100 million bucks price tag appears]

00:44

will be sold for salvage value or scrap for ten million bucks in 20 years then

00:49

the decline in total value over that time will be ninety million bucks yep [Decline in value calculation]

00:54

over twenty years or four and a half million dollars each year if the company

00:59

used straight-line depreciation to account for the loss in value of that [Straight line on a value/time graph]

01:04

smelting Factory but under double declining balance depreciation systems

01:09

the deduction rate is essentially double the straight-line amounts it's still the

01:14

same total amount of deduction it's not like the value of the tractor factory

01:18

changed either at purchase time or scrap time but the speed and timing of the [Timeline of depreciation]

01:24

depreciation changed to favor high depreciation in the early years giving

01:29

the company lower profits but also lower taxes [The first 5 years on the timeline are highlighted]

01:32

well the accounting rationale follows suit the utility or value of the asset

01:37

is in fact not declining in true market value in a steady state straight-line [Stop sign appears over the value graph]

01:44

over twenty years try to convince a buyer that your car

01:47

has depreciated only five percent in value a year after you bought it new [Car for sale on eBay]

01:51

yeah not happening depreciate way more than that so in double declining balance

01:55

depreciation instead of deducting four-and-a-half million bucks a year the

01:59

company would deduct nine million a year each year with some adjustments along

02:04

the way and yes we're way over generalizing on that statement until [Overgeneralizing flashing red]

02:07

that smelting Factory was fully deducted away to whatever terminal salvage value

02:12

or scrap value they predicted it would then sell [Factory value declining]

02:15

for that is if a normal depreciation was taking four-and-a-half million bucks a

02:20

year for 20 years or four-and-a-half percent of the total initial cost then [Straight line depreciation per year]

02:24

double declining balance depreciation would take double that number or nine

02:30

percent of the hundred million dollars in year one

02:34

so they deduct nine million right upfront and your one right goes from 100

02:38

to ninety one on the sheets and in reality that's probably a lot closer to [Price tag decreasing]

02:42

what the actual loss and market value of the smelting machine and would look like

02:46

all right well then in year two double declining balance depreciation would

02:49

again take double the flat rate of that four inhabitant they double it to nine

02:54

percent of the remaining book value of the smelter or nine percent of the

02:58

remaining 91 million that it's worth or about 8.2 million in incremental [Double declining balance depreciation per year]

03:03

depreciation for that year leaving the value ninety one - 8.2 or eighty two

03:08

point eight million dollars in year three the value of the shelter would

03:12

drop another nine percent to about seventy five point four million say we

03:16

did all the math therefore there no extra charge and in year four down nine [Post it note showing the calculation]

03:20

percent again to around sixty eight point six million dollars so up to this

03:24

point the set of deductions would look like this there we go all that stuff you [Amount depreciated in the first 4 years is shown]

03:28

notice that as we've gone along here we've taken the beginning of the year

03:32

book value of the smelter as the starting point against which to take our

03:37

nine percent deduction if we take nine percent always well we'll never get to

03:42

zero or rather to the scrap value target there of ten million bucks right nine [The value in the 20th year is shown]

03:47

percent and keep just being a tiny tiny amount on those out years so in practice

03:51

at some point when companies have depreciated the crap out of their

03:55

capital assets well then they switch to straight-line depreciation in this case

03:59

after say year five our smelter would be valued at sixty two point four million

04:05

dollars ish with fifty two point four million left to depreciate to hit that

04:10

ten million dollar scrap value for about three point five million a year for the [Calculation of loss per year is shown]
