📖 How It Works
We project income with raises and inflate expenses year-by-year. Real Income = Nominal / (1+inflation)^years. Purchasing Power = (Real Income / Base Expenses) × 100. Required Income = Inflated Expenses / (1 − Savings Rate). Income Gap = Required − Actual.
Real Income
Nominal income adjusted for inflation—true purchasing power.
Required Income
Income needed to cover inflated expenses + savings.
