Lifestyle Inflation Calculator
See how much of your raise went to spending vs savings. Are you actually getting ahead, or just spending more?
Lifestyle inflation (or lifestyle creep) is the silent wealth killer: as your income grows, your spending grows with it, leaving you no better off than before. A $15K raise that leads to $12K more in spending means you're only capturing 20% of your hard-earned increase. This calculator shows exactly where your raise went — and how much wealth you're sacrificing to lifestyle upgrades.
Of your $15,000 raise, 47% went to spending and 53% to savings. Your savings rate went from 25.0% to 30.7%. You're capturing a healthy portion of your raise.

Real-world examples
The 100% creep: $15K raise, $15K more spending
Income went from $60K to $75K, but expenses went from $45K to $60K. Inflation rate: 100%. Savings rate stayed at 25%. You're earning more but not building any additional wealth.
The disciplined: $20K raise, $5K more spending
Income: $80K→$100K, expenses: $55K→$60K. Inflation rate: 25%. Savings rate jumped from 31% to 40%. This person captures 75% of their raise — the path to financial freedom.
The reverse creep: spending MORE than the raise
Income: $70K→$80K (+$10K), expenses: $50K→$65K (+$15K). Inflation rate: 150%. Savings rate dropped from 29% to 19%. Earning more but saving less — a dangerous trap.

Frequently asked questions
What is lifestyle inflation?
Also called lifestyle creep — when increased income leads to proportionally increased spending, leaving you no better off financially. A 20% raise that leads to 25% more spending means you're actually going backwards.
How do I avoid lifestyle creep?
When you get a raise, automatically direct at least 50% of the increase to savings/investments before adjusting your lifestyle. You'll still enjoy some upgrade while building wealth.
Is some lifestyle inflation okay?
Absolutely — the point isn't to never upgrade your life. The 50/50 rule is a good guideline: save 50% of any raise, spend 50% on lifestyle upgrades. You improve your life AND build wealth.
What's the long-term impact?
Over a 30-year career, capturing 50% of raises vs 100% lifestyle creep can mean the difference between retiring at 50 vs 65. Each dollar of lifestyle inflation requires ~$25 more in retirement savings (at 4% SWR).
