Comparison Matrix
Dual Career Path
Two scenarios, one form. Left column is the stay path — your current city, current rent. Right column is the move path — new income, new cost floor. The delta bar below shows which one wins, and by how much.
Each column keeps its own state. Change the rent on either side and only that side updates. The delta bar re-computes live.
Comparison Matrix · Dual Scenario
Lock Variables · 0/5 synced
Locked fields share one value across both scenarios — change in either column, change in both.
Scenario A · Stay
Geographic Arbitrage · Migration Horizon
Migration Horizon · Break-even Point
Break-even at month 5.0
Monthly Gain After Move
$1200
Verdict: Fast_Payback
Break-even inside 6 months — strong migration signal
Surplus · here
$1500
Surplus · there
$2700
5-year net
$66000
Monthly gain = (income − cost)there − (income − cost)here. Break-even = move cost / monthly gain. If you won't stay past break-even, the move is a bet against yourself.
Scenario B · Move
Geographic Arbitrage · Migration Horizon
Migration Horizon · Break-even Point
Break-even at month 5.0
Monthly Gain After Move

Monthly gain = (income − cost)there − (income − cost)here. Break-even = move cost / monthly gain. If you won't stay past break-even, the move is a bet against yourself.

How the matrix works
Each column is a namespaced instance of the tool. Scenario A writes to
relocation_monthly_gain__a;
Scenario B writes to
relocation_monthly_gain__b.
The delta bar subscribes to both keys. Inputs never cross-contaminate.
Same deterministic math as the standalone tool — just run in parallel. Nothing is sent to a server.
