The psychology behind Rent vs Buy Calculator
Rent vs Buy Calculator is designed to interrupt status quo bias before it becomes an expensive default. Most people do not fail at arithmetic — they fail at noticing which number their brain treats as the whole story.
Behavioral research shows that attention is scarce. When a monthly payment, refund, or social comparison pops first, other facts (total interest, match left on the table, purchasing power, runway) fade into the background. This tool puts the neglected number beside the tempting one so trade-offs are visible.
Use the output as decision hygiene. Re-run when income, rates, or goals change. Pair the estimate with a concrete next action: automate a transfer, adjust withholding, claim an employer match, or schedule a 15-minute money check-in. Insight without a habit decays quickly.
These estimates are educational. Rules, markets, and tax brackets change. Confirm details with authoritative sources linked below and with qualified professionals before you sign, contribute, or claim benefits. PsyFi exists to turn a clear moment into lasting behavior change — not to replace personalized advice.
If the result surprises you, that is useful data about status quo bias. Surprise is often where better plans start: rename the goal, shrink the time horizon, or add a commitment device so present-you and future-you stop negotiating from opposite sides of the table.
