ClarityCalc
The brutally honest answer to rent vs. buy.
A user inputs their target home, local rent, and finances, then instantly sees a side-by-side wealth projection with a plain-English verdict — followed by a job-loss stress test and a shareable report they can take to agents or partners.
What makes people lean in
The instant 'Verdict' screen that flatly tells you 'Keep renting — you'd be $112,400 richer in 10 years' with an animated dual-line wealth chart, the moment most calculators would push you to buy.
The case for building it
The core pain is distrust of agent/lender-biased calculators and paralysis over conflicting advice. A single screen that delivers an unbiased numeric verdict — including opportunity cost and a runway stress test no free tool shows — proves the differentiator immediately. It's cheap to build, drives SEO traffic, and the share/report feature seeds viral and lead-gen loops, validating the freemium-to-premium case.
