ipersonal = [∑(Spendingc × ic)] / Total Spending
Lifestyle Cost (20 years) = Total Spending × (1 + ipersonal)20
Real-World Compounding Projections
Official 2.5% vs Personal 5.8%
If a household spends heavily on housing (8% rise) and healthcare (6% rise), their weighted inflation rate is 5.8%. In 20 years, a $3,000/month lifestyle will cost $9,228, compared to only $4,916 under official CPI rates.
