prescriptive budgets are designed to
0:12
give you clear parameters for your
0:14
spending decisions in prescriptive
0:16
budgeting the plan is your master guide
0:20
all of your efforts are focused on
0:22
keeping your behaviors in line with the
0:25
plan prescriptive budgets provide you
0:28
with great structure for your spending
0:30
choices they're particularly useful if
0:32
you're budgeting to be more aware of
0:34
where your money is going and more
0:36
intentional around spending and saving
0:38
it these types of budgets are also
0:41
incredibly effective to combat
0:43
overspending and common financial
0:45
hazards that could hurt long-term
0:47
financial success with prescriptive
0:50
budgeting the categories that you
0:52
defined in your pre-work and the
0:55
averages that you calculated for those
0:57
categories become the cornerstones of
0:59
your budget structure keep in mind that
1:03
these budget models will require a time
1:05
investment for planning and for
1:08
monitoring they can also become overly
1:11
complicated and feel restrictive if
1:14
you're too aggressive and detailed in
1:16
your planning
1:18
a prescriptive budget with its detailed
1:21
planning and spending allocations is
1:23
what most people think of when they
1:25
think of a traditional budget plan three
1:29
common prescriptive approaches are
1:31
zerobased budgeting proportional
1:33
budgeting and the envelope system of
1:37
budgeting the zero based budgeting model
1:40
prioritize assigning everything to a
1:42
predetermined spending category you
1:45
start at $0 and you end at zero dollars
1:49
with every penny accounted for this
1:53
approach is a great way to practice
1:55
financial discipline and it allows you
1:57
to focus on achieving your financial
1:59
goals by ensuring you incorporate them
2:02
into the plan
2:04
shorter budgeting periods of 1 to two
2:06
weeks work well for this structure
2:08
because you can plan your allocations in
2:10
smaller increments and make little
2:12
adjustments quickly and more easily if
2:16
you decide to use a version of zero based
2:18
budget be sure to set aside sufficient
2:21
time for planning in advance and also
2:24
time for monitoring yourself during that
2:27
budget period
2:29
also keep in mind that a very detailed
2:31
and specific zero based budget can lead
2:34
to the plan being overly complicated and
2:37
restrictive which can lead to it being
2:40
ignored and abandoned since you create
2:43
it and you control the plan monitor how
2:46
you use it to manage these potential
2:49
challenges so what does a zero based
2:52
budget look like it may look like this
2:56
start with your anticipated income
2:58
include in that income everything you
3:01
plan to have available for that budget
3:03
period whether that's earnings a portion
3:06
of your financial aid refund or another
3:08
resource like family financial support
3:11
next list spending categories and
3:15
average costs that you calculated in
3:17
each category during your budget
3:20
pre-work add up the averages and compare
3:23
it to your income
3:25
if income and spending don't equal each
3:28
other you have some decisions to
3:31
make use your current behaviors and
3:34
financial goals to inform changes to
3:36
your budget category
3:39
allocations what spending do you need to
3:42
prioritize where can extra resources be
3:45
directed or what could be reduced if you
3:48
need to reduce your spending consider
3:51
making smaller incremental changes to be
3:54
realistic about what you can and will
3:57
adjust in your
3:58
behaviors once you have your
4:01
allocations keep spending within those
4:05
parameters and when it's time for the
4:07
next budget period move any leftover
4:10
money directly into your savings and
4:13
start your budget plan for zero again
4:18
proportional budgeting allocates
4:20
resources based on set percentages of
4:23
your total income in proportional
4:26
budgets you group specific spending
4:28
categories into larger key
4:30
types commonly those types are needs
4:34
wants savings and debt repayment
4:38
structuring your plan based on these
4:40
groupings ensures that you can stay
4:41
within your allocations while still
4:43
having flexibility within each of them
4:46
to direct your resources as needed and
4:48
as circumstances and opportunities
4:51
change a well-known proportional budget
4:54
is a 50-30-20 approach
4:57
this means 50% of your allocation is
5:00
going towards
5:02
needs 30% towards wants and 20% towards
5:06
savings and debt
5:08
repayment other percentage allocations
5:11
may work better for your
5:13
circumstances the 70-20-10 approach
5:16
directs you to allocate 70% of your
5:18
income to cover essential living
5:20
expenses
5:21
20% is for savings and debt repayment
5:24
and 10% is for personal
5:27
spending ultimately the percentage that
5:30
you attribute to each area depends on
5:33
your resources and priorities so feel
5:36
free to adjust percentages or adjust the
5:38
categories based on your circumstances
5:41
and goals proportional budgeting works
5:44
best if you have regular predictable
5:46
income that you can portion out into
5:48
needs wants and savings if you have less
5:52
predictable income or if your expenses
5:54
don't fit nicely into simplified
5:57
categories you may need to modify this
5:59
approach before it's useful to you
6:02
whether you follow a 50-30-20 rule a
6:06
70-20-10 rule or set your own rules the
6:10
key to this approach is to align your
6:12
percentage allocations with your
6:14
priorities and goals so what does a
6:17
proportional budget look like a 50-30-20
6:21
budget could look like this start with a
6:24
plan for percentages and spending areas
6:26
you'll use and then divide your net
6:29
income into each
6:31
area be sure to list where the
6:34
categories you identified in your budget
6:36
pre-work fall in this system you can
6:39
then choose if you want to divide the
6:41
allocations even further into
6:44
subcategories or if you just want to be
6:46
aware of overall behavior in each area
6:49
and let things flow as
6:51
needed and if you prefer to see your
6:54
budget in tables and cells this is
6:56
another way you could plan out a
6:58
proportional budget however you draft
7:01
your plan remember that your allocations
7:03
are driven by percentages you determine
7:06
for each spending area
7:08
this may mean additional allowances in
7:11
some categories and major cuts in others
7:14
when compared to your current
7:16
behaviors now the envelope system of
7:18
budgeting is typically used in
7:21
conjunction with another strategy like
7:23
zero based budget or a proportional
7:26
budget it's exactly what it sounds like
7:29
with the envelope method of budgeting
7:31
you label physical envelopes for your
7:35
identified spending categories
7:38
after allocations are determined you'll
7:40
deposit that amount of cash into each of
7:44
your labeled envelopes you only have the
7:47
cash that's in the envelope to spend and
7:49
once it's gone it's gone for that budget
7:52
period this is a particularly effective
7:55
method if you're budgeting to try to
7:57
manage overspending or impulse spending
8:00
habits use small denominations of cash
8:03
as much as
8:04
possible and don't cheat don't leave
8:07
cash in the envelope for future spending
8:09
or borrow it from other
8:11
envelopes if you have money left over in
8:14
an envelope at the end of the period
8:16
immediately deposit it into your
8:19
savings the envelope system works
8:23
because both the physical connection to
8:25
cash and the psychological impact of
8:28
watching it dwindle in the envelope have
8:30
powerful effects on behavior you feel
8:33
yourself part with every single dollar
8:36
as that large stack gets smaller and
8:40
smaller and smaller and it works in many
8:44
different scenarios to help you
8:45
visualize your spending and remaining
8:47
available resources for example if you
8:50
study abroad you can withdraw foreign
8:52
currency and divide it into specific
8:54
envelopes based on planning rather than
8:58
constantly trying to convert money in
8:59
your head for each purchase you just
9:02
focus your spending to the currency in
9:05
those
9:06
envelopes this ensures you don't
9:08
inadvertently overspend because you've
9:11
done all the planning in advance you can
9:14
just live the experience and use the
9:16
money that's available
9:19
if you plan to utilize this approach
9:21
it's important that you commit to
9:23
spending cash from your envelope as much
9:26
as possible if you start to cheat and
9:29
use your card for convenience you risk
9:32
losing track of what's been spent from
9:34
the envelope and what's been spent
9:35
through other
9:37
means some banks have what they call
9:39
digital envelopes so that you can manage
9:41
this approach virtually if you don't
9:44
like using cash and that aligns more
9:46
closely with your natural purchasing
9:48
preferences it's something to explore
9:51
but keep in mind that implementing the
9:53
system virtually won't have as strong of
9:56
a psychological influence if you're
9:58
trying to control risky spending
10:01
behaviors also keep in mind your
10:04
personal security never have large
10:07
amounts of cash sitting around in an
10:10
unsecured dorm room or in a shared
10:12
living space lock your envelopes up and
10:16
only carry the cash you need and plan to
10:19
spend
