Results
Amount needed in 20 years to match today's purchasing power of NT$1M
NT$1.49M
= NT$1M × (1 + 2%)^20
Reverse: NT$1M in 20 years equals today's
NT$673K
Purchasing power loss: 32.7%

Formula: future nominal = present × (1 + inflation)^years; real purchasing power = nominal ÷ (1 + inflation)^years. Outputs are math estimates only; real inflation fluctuates.

Even at a moderate 2% annual inflation, 30 years erodes purchasing power by roughly 45%. Retirement plans should always use real returns (after inflation) to reflect actual wealth growth.
