What-if — A Real Comparison

HOW IT STARTED

She typed one sentence into the box.

No forms, no sliders, no budget spreadsheet. What-if already knows what is in her plan, so all it needed was the question.

YOUR QUESTION

What if Sam and I move in together next spring?

THE FULL RUN

Here it is, all of it.

Nothing below has been trimmed to look impressive. This is the screen she saw, at full size, with every implication What-if raised across all ten areas of her plan.

THE SCENARIOMove in with Sam next spring

Model another scenario

↑What improves

↑Roughly $620 a month back once rent is split

↑Time together stops competing with the commute

↑A real answer about the two of you, a year early

↑The trip she keeps postponing becomes affordable

↓What it costs

↓Six weeks of paying two leases at once

↓Her flat stops being where the group gathers

↓Solo time she did not know she relied on

↓Her gym and her run club are both across the river

↓Her safety net now has to cover a household

YOUR PLAN TODAYWITH THIS CHANGE

Career

Two years in, up for a bigger brief

→

↑A shorter commute gives her back about five hours a week

↓She loses the quiet flat where her best Sunday work happens

Financial

Rent takes 34% of what she brings home

→

↑Splitting rent and utilities frees roughly $620 a month

↓Six weeks of double rent in the handover, about $1,400

↓Her safety net now has to cover a household, not just her

↑One set of deposits, insurance and internet instead of two

Education

Two evenings a week on the design course

→

↑Someone in the house to hold her to the two evenings

↓Study nights become a conversation, not just a decision

Relationships

Together three years, two apartments

→

↑No more evenings lost to travelling between two homes

↑A real answer about whether this works, a year sooner

↓Small friction she used to escape now has nowhere to go

↓Neither of them has said out loud what happens if it ends

Family

Home for most holidays, Sunday calls

→

↑Room to host her sister when she visits

↓Holidays turn into a negotiation between two families

↓Her mum will read this as a bigger step than she means it

Health

Three gym sessions a week, sleep is decent

→

↓The gym she actually goes to is twenty minutes away now

↓Two different sleep schedules in one bedroom

↑Cooking properly gets easier when someone else is eating

Housing

One bedroom, lease renews in April

→

↑The same money buys noticeably more space together

↓Only one name goes on the lease unless she asks for both

↑A chance to test the neighbourhood before a longer lease

Community

Her flat is where the group meets

→

↓The hosting that holds her friend group together moves across town

↓Her run club is on the other side of the river

Experience

One big trip a year, saving for it

→

↑The money saved covers the trip she keeps postponing

Legacy

No will, no named emergency contacts

→

↓Living together gives Sam no legal standing whatsoever

↑A reason to finally name a contact and write things down

THE 10-YEAR LOOK-AHEADXCL PLUS

On your plan today

Two households, steady savings, and a relationship she is still deciding about in 2036.

With this change

A shared home, a clear answer about the two of them years sooner, and a friend group and a set of solo habits she would have to rebuild on purpose.

Like where this leads?

Applying saves this decision for her next plan. It will not change anything right now.

DiscardApply this scenario

What-if is an informational modeling tool, not professional financial, legal, medical, or relationship advice. Outcomes are hypothetical and not guaranteed.

WHAT IT CAUGHT

Three of these she had not considered at all.

Twenty-nine implications came back. Most confirmed what she already suspected. These three did not, and each one came from an area she would never have thought to check.

HOUSING

The six weeks nobody budgets for

↓

Her lease ends six weeks after Sam’s new one starts

Her renewal is in April. Sam’s new lease starts in March. What-if read both dates straight off her plan and put a number on the gap: roughly $1,400 of rent for a flat neither of them will be living in. It is not a hidden cost. It is just one nobody looks for until the second lease is already signed.

COMMUNITY

The apartment was the friendship

↓

The hosting that holds her friend group together moves across town

Her flat is where the group meets. Move across the river and the hosting either moves with her or quietly stops happening. That is not a housing cost, it is a community one, and it only surfaces because What-if checks all ten areas instead of the two that look obviously relevant.

LEGACY

Sam has no standing at all

↓

Living together gives Sam no legal standing whatsoever

Moving in together does not make Sam a next of kin, an emergency contact, or anyone a hospital is obliged to call. It takes about ten minutes to fix and almost nobody does, because the question never comes up until the one day it matters most.

ONE RUN

That was one scenario. She has seven more this month.

AFTER THE RUN

Leave it, or let it change what comes next.

Nothing is written while she reads. Applying does not edit the plan she is living by either, it saves the decision as an input. The next time her plan regenerates, her goals, next steps and to-dos come back rebuilt around it.

NOTHING IS WRITTEN

Leave it

She closes the scenario and her plan is untouched, down to the last to-do. The run stays saved either way, so she can reopen it, re-read it or compare it next month without spending another run.

HER NEXT PLAN · REGENERATES 1 NOVEMBER

Housing

GOALRenew the one bedroom in April

NEXTAsk about a twelve month renewal rate

TO-DODiarise the renewal notice date

Financial

GOALGet rent under 30% of take-home

NEXTReview the budget in January

TO-DOCancel the two subscriptions she does not use

Relationships

GOALKeep the weekly date night going

NEXTBook the February trip

TO-DOPlan something for the anniversary

Nine items, nine unchanged. The scenario never touched them.

FOLDS INTO THE NEXT PLAN

Apply it

The decision is saved as an input, not as an edit. Her live plan does not move today. When the next one regenerates, every goal, next step and to-do is rebuilt with the move already assumed. Only one scenario can be applied at a time.

HER NEXT PLAN · REGENERATES 1 NOVEMBER

Housing

GOALSign a joint lease with Sam in March

NEXTGet both names on the lease and the utilities

TO-DOGive notice on the April renewal by 1 February

Financial

GOALCover the six week overlap without touching savings

NEXTPut aside $350 a month from now until March

TO-DOOpen a shared bills account before the move

Relationships

GOALKeep the weekly date night going

NEXTAgree what happens if it does not work out

TO-DOWrite down what you each expect of the space

Indigo marks what this scenario changed. Eight of her nine items came back different.

OR ASK IT DIFFERENTLY“And if we wait until September?” is a new question and a new run. She has seven left before the first of next month.
