Frequently asked questions
What inflation rate should I use?
US historical: ~2.5%/year; Fed target 2%. Vietnam: 3–4%. Global average: ~3%.
What's a real return?
It's the rate after stripping inflation — actual purchasing-power gain. 8% nominal with 3% inflation = ~4.85% real.
How is purchasing power different from nominal price?
$50K in 2000 ≈ $90K in 2024 in purchasing power. Nominal numbers rise but so do prices — real value tells you whether you're actually better off.
