WealthTrack MY: Personal Finance Platform
WealthTrack MY is a comprehensive personal finance platform built specifically for Malaysians. Rather than relying on tedious transaction-by-transaction expense tracking, it adopts a practical "Fixed Commitments + Envelope Allocations" budgeting methodology that encourages long-term financial planning with minimal daily effort. The platform combines budgeting, tax planning, debt management, net worth tracking, retirement planning, and Islamic financial tools into a single dashboard. It also incorporates Malaysian-specific financial rules—including LHDN PCB tax calculations, EPF 3-account restructuring, Rule of 78 hire-purchase settlements, reducing-balance mortgages, and Zakat obligations—to provide users with a complete picture of their financial health.
