Why this matters
Lifestyle inflation can reduce the long-term impact of higher income. Keeping part of each raise invested or saved can compound over time.
Example
If your annual raise is 10,000 and 40% goes to new spending, 4,000 is absorbed by lifestyle inflation and 6,000 remains available for saving, investing or debt payoff.
How to use the result
Use the split to set a rule before the raise disappears into recurring expenses. Even saving a fixed share of each raise can improve long-term flexibility.
Limitations
The calculator does not judge whether higher spending is bad. Some increases, such as housing, childcare or healthcare, may be necessary. It simply shows the tradeoff between new spending and extra saving.
