A planner that calculates how long until you can afford to move out, comparing living alone vs roommates in your city.
The problem people are complaining about
On 2026-10-21, a thread titled “How can I save up while living with parent? Is moving in with roommates possible with my finances” reached #23 in our daily ranking of personal finance problems on Reddit. In personal finance, people most often struggle with budgets, debt, taxes, savings accounts, retirement contributions and money decisions after big life events; this one stands out because the person asking has a concrete, repeatable need rather than a one-off emergency. When the same question keeps appearing in public, it usually means existing products either don't reach these people or don't answer the question in the way they need. That gap is what Move-Out Planner aims at.
Who the customer is
Young adults living with parents who want to know how long it will take to afford moving out, alone or with roommates.
In short, the first customer to target is: Young adults living with parents. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.
The idea
Move-Out Planner is a free tool + affiliate idea. A planner that calculates how long until you can afford to move out, comparing living alone vs roommates in your city. It makes money through affiliate commissions from savings accounts, roommate/rental platforms.

Pricing guess
Estimate: free; affiliate payouts from savings accounts and roommate platforms. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Weekend: calculator with rent inputs and savings timeline. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Launch the calculator and measure shares and time on page.
- Track affiliate click-through to savings accounts.
- Add city rent data for the top 20 cities and see whether traffic grows.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives
Generic budget calculators, SpareRoom/Roomies for roommates Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.
Risks
- Rent data must be current.
- Low willingness to pay.
- Many budget calculators exist.
How we scored it
Opportunity score (6/10) is an editorial judgement combining four factors: how strong and frequent the demand looks, whether the customer already spends money on the problem, how crowded the alternatives are, and how much effort the first version takes. Signal score (3/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See how it works.
