What is Test Plan and how should I use it?

What is the Test Plan and how should I use it?

Last published on: August 28, 2025

 

 

Because Income Lab plans are built for ongoing monitoring and management, with retirement income that dynamically adjusts to changing household and economic circumstances, you may be curious how a given dynamic retirement income plan might play out. You may have questions like:

  • How likely is it that income will be higher or lower than expected?
  • How high or low could the monthly income be?
  • What might I expect, on average, for monthly income?
  • How likely is it that income will ever go below minimum needs?
  • If income were to go below minimum needs, how long might a period of below-minimum income last?

In other words, users will want to explore the possible magnitude and timing of income changes. The Test Plan provides historical answers to these questions and more. From each monthly point in recorded history, the Test Plan tracks a household identical to the current household through time. Each household follows a plan identical to the current plan, using only data available at each point in history, increasing or decreasing income when the plan calls for it. While past outcomes do not guarantee future results, this data allows users to provide context for how dynamically-managed retirement income plans have played out in the past.

Here are a few videos on the different Test Plan sections that may help:

this video

walks you through the plan test results

0:15

income page the first section

0:19

looks at the overall lifetime income

0:21

experience

0:22

of these households across the entire

0:24

life of the plan

0:26

on the left we see how many households

0:28

received more

0:30

income over their lifetime than was

0:32

planned

0:33

of course it's natural to ask how much

0:36

more income did they receive

0:38

did the outcomes vastly exceed

0:40

expectations

0:41

or were the differences small so below

0:44

the overall percentage

0:46

you will find the average amount of

0:48

excess income

0:49

as well as the percentage received in

0:51

the best case scenario

0:53

on the right we see the same statistics

0:56

for households that had less overall

0:58

income than planned

1:00

you will often find that even in the

1:02

scenarios where households were not able

1:04

to achieve their planned lifetime income

1:07

their actual lifetime income lagged only

1:09

by small amounts

1:11

both on average and in the worst case

1:13

scenario

1:14

please note the data summarized were

1:17

lifetime income experiences

1:19

for information on how income may vary

1:21

in any given month

1:23

we can look to the next section

1:26

in retirement just as during our working

1:28

years

1:29

people adjust as their financial

1:31

situation

1:32

gets better or worse and minor

1:34

adjustments

1:35

can rescue most retirement plans this

1:38

data

1:39

paints a much better picture of what to

1:41

expect in retirement

Video: Income Adjustments

Video Transcript - Income Adjustments

welcome

to the income lab video tutorial series

0:11

this video

0:12

walks you through the plan test results

0:15

income page the income adjustment

0:18

section

0:18

examines the individual changes in

0:21

monthly income

0:22

that households make over time this data

0:25

helps answer the questions

0:27

how often did households make income

0:29

adjustments

0:30

and how big were those adjustments

0:33

in this section you can see the size of

0:36

the average pay raise

0:37

or pay cut and how frequently it

0:40

occurred

0:41

you can also see the size of the largest

0:43

income adjustments

0:44

increase and decrease and the range in

0:47

size

0:47

for 90 percent of all the adjustments

0:51

note that for downward adjustments we

0:53

focus in this section on adjustments

0:55

that bring

0:56

income below the originally planned

0:58

level

0:59

we exclude downward adjustments that

1:01

take a household from a level above its

1:04

plan

1:04

to a level that is still above plan but

1:07

slightly less so

1:09

in retirement just as during our working

1:11

years people adjust

1:13

as their financial situation gets better

1:15

or worse

1:17

and minor adjustments can rescue most

1:19

retirement plans

1:20

this data paints a much better picture

1:23

of what to expect in retirement

0:15

income graph retirement is not a

0:17

one-time event

0:19

it's a dynamic process with adjustments

0:21

for changing circumstances

0:24

this graph is a powerful way to show

0:26

clients

0:27

what realistic dynamic retirement income

0:30

experiences

0:31

can look like to get a better feeling

0:34

for what retirement income

0:35

could look like for a particular

0:37

household following a particular plan

0:40

we have cloned the household and put

0:42

them at every single month in recorded

0:44

history

0:45

which for us goes back to 1871

0:48

and let them live out their retirement

0:50

according to this plan

0:52

increasing their income when the plan

0:54

allows and decreasing it

0:56

when the plan suggests the income

0:59

scenarios in this chart

1:00

range from the best to the worst ranking

1:04

by overall income experience if you

1:07

imagine the retirement

1:08

income journey as a staircase each step

1:11

up represents a pay raise

1:13

and each step down a pay cut the nominal

1:17

income graph includes income adjustments

1:20

based on changes

1:21

in inflation naturally you won't find

1:24

inflation adjustments on the real graph

1:28

if you'd like to focus on just one or a

1:31

few scenarios

1:32

you can click on the scenario label to

1:34

take it out of the chart

1:36

and bring it back in for example if i

1:39

wanted to show a client the middle

1:41

80 of these scenarios i could unselect

1:44

every label except the 90th and 10th

1:47

percentiles

1:49

for most plans you will see that paid

1:51

raises in retirement

1:52

are available across a range of

1:54

scenarios

1:55

because of these increases in income pay

1:58

cuts

1:59

often do not bring income below the

2:01

originally planned level

2:03

in most cases you will also see that

2:06

even in less fortunate circumstances

2:08

relatively small adjustments can keep a

2:11

plan

2:11

on track visualizing this

2:15

will help clients feel confident in your

2:17

advice

Video: Legacy

Video Transcript - Legacy

welcome to the income lab video tutorial

0:03

series this video walks you through the

0:06

planned test

0:07

legacy results page to get a better

0:10

feeling for how much legacy a particular

0:13

household could leave behind when

0:15

following a particular plan we have

0:17

cloned the household and put them in

0:19

every single month in recorded history

0:21

which for us goes back to 1871 and let

0:25

them live out their retirement according

0:27

to this plan making the call for income

0:30

adjustment along the way the data shown

0:33

here range from the lowest to the

0:36

highest end of planned legacy across all

0:39

hypothetical households in the plan test

0:42

by examining the line graph you can see

0:45

how total portfolio balances change

0:48

through time when following this plan if

0:51

you wish to simplify the graph and focus

0:54

on just one or a few scenarios you can

0:57

click a scenario label to add or remove

1:00

it from the chart for example if you

1:03

want to focus on the middle 80% of

1:06

planned test outcomes you could unselect

1:09

every label except the 90th and 10th

1:12

percentile fields

1:16

unlike graphs you may have seen

1:18

elsewhere where end of planned portfolio

1:20

balances range from $0 to millions

1:24

a typical income lab plan exhibits a

1:27

tight grouping of legacy results usually

1:30

close to the legacy goal that's because

1:33

in a plan that includes ongoing

1:34

management income adjustments are always

1:37

made with the households legacy goals in

1:40

mind this means that a household that

1:42

follows a well designed plan does not

1:45

run out of money but also does not

1:47

vastly overshoot its legacy goals for

1:50

example if the household wishes to leave

1:53

1 million dollars behind but has say 3

1:57

million left in the middle of retirement

1:59

the plan may suggest an increase in

2:01

income because the household is at risk

2:04

of leaving too large a legacy conversely

2:07

if a legacy goal appeared to be at risk

2:10

the plan may have called for a reduction

2:12

in spending in order to hit that goal by

2:16

implementing a plan income lab will be

2:18

able to notify you in situations like

2:21

these to help households stay on track

2:23

if the household is on track to leave

2:26

much more than planned you can help them

2:28

decide whether to spend more money give

2:32

assets to the heirs give more to charity

2:35

or increase their legacy goal regardless

2:39

of what they choose it's a way you can

2:40

show value by knowing when to have that

2:42

conversation

2:44

overall this chart is a great

2:46

opportunity to show the value of ongoing

2:49

plan

2:50

management and to east worries clients

2:53

may have about running out of money
