The formula library that gave me real visibility into my money. Net worth tracking, savings rate, lifestyle creep detection, FIRE projections, and emergency fund runway — all automated.
Most people have no idea where their money actually goes. They check their bank app, guess at their savings rate, and hope for the best. This formula library gives you real-time dashboards that auto-calculate everything — true savings rate, expense categorization, lifestyle creep detection, FIRE milestone tracking, and emergency fund runway. The visibility alone changes behavior.
