Calculating Depreciation (Straight-Line, Units of Activity & Declining Balance Methods) - YouTube

in Chapter ten you learned about
[2]
depreciation so there's three different
[5]
depreciation methods we have the
[7]
straight-line method the units of
[10]
activity method and the declining
[12]
balance method let's first look at the
[15]
straight-line method so to calculate
[18]
your depreciation expense in the
[20]
straight-line method we take our cost
[22]
minus the salvage value to get our
[26]
depreciable cost and then we take that
[29]
depreciable cost and we divide it by our
[31]
useful life in years to get our annual
[34]
depreciation expense under units of
[40]
activity we're gonna start off a similar
[42]
way we start off with cost minus salvage
[45]
to get our depreciable cost but then it
[48]
changes up a bit we take that
[51]
depreciable cost and we divide it by the
[53]
total units of activity in that assets
[57]
life and that's going to get us a
[59]
depreciable cost per unit then we take
[63]
that depreciable cost per unit and
[65]
multiply it by the units of activity
[66]
during this one year and that will get
[70]
you your depreciation expense for the
[75]
declining balance method it's a little
[76]
bit different we start off by taking
[79]
cost minus accumulated depreciation to
[83]
get our book value then your textbook
[86]
says you take the book value and you
[89]
multiply it by double the straight-line
[91]
rate
[92]
well that's the same thing as your book
[95]
value times two over the number of
[98]
useful years and then that will equal
[103]
your depreciation expense so let's work
[108]
through an example
[109]
maz贸n a Tico purchased equipment on
[112]
November 1st 2019 the equipment cost
[116]
$40,000 and has a salvage value of $2000
[121]
it's expected useful life is five years
[124]
and 10,000 working hours in 2019 the
[128]
equipment was used for 300 hours and in
[132]
2020 the
[133]
equipment was used for 2,800 hours so we
[138]
need to calculate the depreciation
[139]
expense for 2019 and 2020 under each
[145]
depreciation method so there's a few
[148]
pieces that we can take from this
[150]
problem that's going to help us figure
[153]
out our depreciation expense first is
[156]
our cost so we look to see how much did
[160]
this equipment originally cost and we
[163]
see that's $40,000
[165]
then it's salvage value at the end of
[169]
its life
[169]
what could we sell this equipment for
[171]
that's 2,000 its life in years is five
[177]
years and its life in units is 10,000
[181]
hours so now we can work on calculating
[185]
our depreciation expense let's start off
[188]
with straight-line so we start off with
[190]
cost minus salvage equals depreciable
[192]
cost so our cost is 40,000 we subtract
[196]
out the 2,000 salvage and our
[199]
depreciable cost is $38,000 then we take
[205]
that depreciable cost divide it by its
[207]
useful life in years to get its annual
[211]
depreciation expense so 38,000 divided
[216]
by five is seventy six hundred as your
[221]
annual depreciation expense
[225]
however in 2019 we didn't have this
[229]
equipment for the entire year we
[232]
purchased it on November 1st so we only
[236]
had it for two months so we take 7600
[240]
times two over 12 so our depreciation
[244]
expense in 2019 is 1266 and 67 cents in
[254]
2020 we have it for the full year so
[258]
it's depreciation expense that year is
[262]
7600
[266]
now units of activity again we start off
[270]
with cost minus salvage so we find our
[272]
depreciable cost to be 38,000 now we
[277]
take that depreciable cost and we divide
[279]
it by its total units of activity in its
[282]
life so 38,000 divided by the 10,000
[287]
hours in its life and we will be
[290]
depreciating at 3 dollars and 80 cents
[293]
per hour so in 2019 tells us that the
[299]
equipment was used for 300 hours so 3
[303]
dollars and 80 cents times 3 hundred
[306]
equals 1140 in 2020 we use this
[316]
equipment for 2,800 hours so 3.8 zero
[322]
times 2,800 equals 10,000 640 you'll
[328]
notice we didn't have to take two
[331]
twelfths of our 2019 depreciation amount
[336]
that's because under units of activity
[338]
it doesn't matter how long you've had
[341]
this equipment for what matters is how
[344]
much you used this equipment during that
[348]
time now our declining balance method we
[355]
want to take our book value and multiply
[358]
it by 2 over the number of useful years
[361]
well remember our book value is cost
[363]
minus accumulated depreciation so for
[367]
our first year here we haven't
[368]
depreciated our equipment yet so our
[372]
cost minus accumulated depreciation is
[375]
still just 40,000 multiplied by 2 over 5
[380]
to get an annual depreciation expense of
[383]
16,000 so 2019 s depreciation we need to
[389]
take that 16,000 multiply it by 2 over
[393]
12 because we've only had it for 2
[398]
so we find out that our depreciation is
[403]
2666 dollars and 67 cents now when we
[410]
need to do this for 2020 we need to find
[413]
our new Book value so our new Book value
[415]
is 40,000 minus our accumulated
[419]
depreciation so our depreciation amount
[422]
from the previous year and then we
[425]
multiply that book value by two over
[429]
five once again to get our depreciation
[432]
expense of that 14,000 9:33 so 2020s
[438]
depreciation since we had it for the
[440]
full year in 2020 it's the full 14,000
[446]
amount so here's all of our depreciation
[453]
expense amounts under straight-lined
[456]
units of activity and declining balance
[461]
declining balance is going to depreciate
[464]
more at least beginning at the start of
[468]
an assets life so you're gonna have more
[473]
depreciation in the early years under
[477]
declining balance straight line straight
[481]
line is the same amount each year as
[484]
long as it's been a full year right so
[487]
if we had it for all of 2019 we would
[490]
see that our straight-line depreciation
[492]
amount was 7600 for both 2019 and 2020
[498]
units of activity units of activity can
[502]
fluctuate right it's all based off of
[504]
how much you use that equipment in that
[508]
year
