You can think of total baseline expenses in a plan as a single block. That block could be steady through the months and years (a "flat", inflation-adjusted expense plan) or it could be an expense plan that follows an Age-Based ("Retirement Smile") pattern. But either way, it is one large block. You can arrive at that by stating a total expense goal or, if you want, by itemizing expenses. If you define it with a single number, you'll just see one color in the "Expense Details" graph. If you itemize, you'll see multiple colors in a sort of "X-Ray" of the total expenses. If some itemized expenses are special - they begin late, end early, or have a different inflation treatment, the app will sometimes create an expense item called "Other Living Expenses" that will fill in some of the spots in the graph to keep total expense goals smooth and even.

I want to quickly cover some examples of
0:02
how Baseline expenses work in income lab
0:07
so in this
0:09
plan I don't have anything complicated I
0:11
just have $5,000 in Baseline
0:16
expenses and if you go to the cash flows
0:18
tab you'll see those 5,000 I even made
0:21
the plan um just have a
0:24
flat um plan here so no retirement smile
0:30
just uh just very basic oh that was
0:35
weird there we go now if I add
0:41
in some baseline expenses from other
0:45
parts of the plan and that you actually
0:48
can do that so for example I have a
0:51
mortgage here and this wouldn't normally
0:54
be how I would do it but I did call it a
0:56
baseline expense and what that's doing
0:58
is just saying hey you know that big
1:01
blue square that cake uh it contains the
1:05
mortgage that's all that's saying versus
1:07
hey the mortgage is an extra thing if I
1:09
call it an other variable expense so I'm
1:11
calling it a baseline expense again not
1:14
normally that's not best practice but
1:16
I'm doing it here just to uh just to
1:18
show the example same with this uh this
1:20
insurance premium I'm calling it a
1:23
baseline expense and so what happens
1:25
then is
1:27
that uh and I adjusted by the way the
1:30
other the other piece so that we still
1:32
had $5,000 or I guess you know it's
1:35
rounding a little funny here but uh
1:37
$55,000 in total expenses and all that's
1:40
happened I also have some some my
1:42
medicare premiums in there as Baseline
1:44
expenses is just I've eaten up or you
1:47
could almost think of it as like an
1:48
x-ray of those of those total Baseline
1:52
expenses so again let's go back I've got
1:55
total Baseline expenses of
1:57
$5,000 that means 2,600 uh 265 of other
2:02
and then you know bunch of other stuff
2:04
in here okay so what we're doing with
2:06
Baseline expenses we're building up a
2:08
total number um here it's $5,000 and
2:12
then that's the Baseline expenses for
2:14
the whole plan I'm just going to
2:15
actually see some details here um in
2:18
this plan because I've because I've
2:19
created a few Baseline
2:21
expenses let's go
2:23
to um another example of
2:27
this here instead of entering a total
2:32
I've entered an itemized Baseline
2:34
expense still
2:36
265 because that's going to add up to
2:38
5,000 got the same other Baseline
2:41
expenses from elsewhere in the plan um
2:44
in this case it's going to look a little
2:45
bit
2:51
different because I've got an actual
2:54
itemized 2000 and change plus these
2:57
other items and so in order to have
3:00
5,000 through the whole plan we we get
3:02
this other living expenses that just
3:04
kind of jumps in here to kind of fill in
3:07
um this the space um that's left um in
3:11
that case so why do we do this well you
3:14
know let's say for
3:15
example maybe instead of just calling
3:17
them living expenses you know maybe this
3:20
was um you know um
3:26
travel was a th000 and
3:30
you know
3:35
food was uh
3:40
126
3:42
um now I actually have something I might
3:44
have gotten that number wrong but
3:47
uh now I have some actual
3:50
items and that
3:53
other Baseline expense item is really
3:57
just as there to say hey you you said
3:59
that you have have um you know $5,000
4:01
yeah I must have typed in the number
4:03
slightly wrong I'm 38 bucks short um you
4:06
said that you have $5,000 in total
4:09
expenses total Baseline expenses you've
4:11
told us what some of those are but
4:13
because these you know the the mortgage
4:15
payment and things end during the plan
4:19
um we got a I know you got something
4:21
else right there's something else it's
4:22
always $5,000 that's what Baseline
4:24
expenses are all about it's about
4:26
establishing a level that you'll have
4:28
for the whole plan if we were doing a
4:31
smile here an age-based um spending path
4:34
then then it would have the smile shape
4:37
but it would always be saying hey this
4:38
is what we're this is what we're going
4:39
for here is always this amount now if
4:44
you make an expense and other variable
4:47
expense what you're saying then is
4:48
that's an expense over and above the
4:51
Baseline so now I here I've I've turned
4:54
that
4:56
um that mortgage payment into an other
4:59
variable
5:00
expense and now here's the mortgage
5:03
payment if I remove that I've got
5:07
$5,000 right so the mortgage payment is
5:09
an extra here so other variable expenses
5:12
are extras that you're they're in the
5:15
plan the plan is to hit those expenses
5:17
to to actually be able to hit those
5:19
expenses um but they're not part of kind
5:21
of the the overall thing that we're just
5:23
kind of trying to hit every month um so
5:27
that's a little bit of an explanation of
5:29
how Baseline expenses work um and a
5:32
couple of ways that you might see them
5:35
typically if you're just itemizing a
5:37
bunch of Baseline expenses you won't
5:39
necessarily see this
5:42
um this other living expenses piece this
5:46
is here just kind of fill in any gaps
5:48
that you've that you've left
5:50
unspecified um because of uh you know
5:54
because of some some strangeness maybe
5:56
around uh you know in this case mortgage
5:59
payments and and um and the term
6:02
premiums but but typically what you'll
6:04
see if you start to itemize is really
6:06
just that instead of one big lump you'll
6:08
kind of start to see a layer cake of
6:10
your um of your Baseline expenses so
6:12
hope this helps
