How this lifestyle change comparison works
The raise absorbed percentage is the monthly spending increase divided by the monthly take-home increase. Spending may exceed the raise; the calculator shows that difference rather than capping it.
The potential value treats the added spending as an end-of-month investment instead. It uses a constant annual return converted to an equivalent monthly rate and excludes taxes, fees, inflation, and market volatility. It is an illustration, not a forecast.
The Consumer Financial Protection Bureau describes lifestyle creep as spending more as income rises and recommends focusing spending choices on personal goals. Investor.gov provides a separate compound-interest calculator for exploring monthly contributions and return assumptions. Read the CFPB discussion.
