Lifestyle Inflation
Compare income and savings rate before vs after a raise. See how much extra spending (lifestyle inflation) you have and how much you could have saved by keeping your old savings rate on the new income.
Understanding Lifestyle Inflation
What it is and why it matters
What Is Lifestyle Inflation?
Lifestyle inflation is when you spend more as your income rises instead of saving the raise. A lower savings rate on a higher income means more spending and less wealth building. Resisting it—keeping spending flat and saving the raise—builds wealth faster.
Savings Sacrificed
“Savings sacrificed” is how much more you would save per year if you kept your old savings rate on your new income. It is (income after × rate before) − (income after × rate after) = income after × (rate before − rate after).
Formula Used
Spending = Income × (1 − Savings Rate)
Lifestyle Inflation ($/yr) = Spending After − Spending Before
Savings Sacrificed ($/yr) = Income After × (Rate Before − Rate After)
Lifestyle Inflation: What It Is and How to Avoid It
Lifestyle inflation is when spending rises with income instead of saving the raise. This calculator shows how much more you spend after a raise and how much you could have saved by keeping your old savings rate.
Lifestyle inflation (sometimes called lifestyle creep) is when you spend more as your income rises. Instead of saving the raise, you upgrade housing, cars, or discretionary spending. The result: a lower savings rate on a higher income and slower wealth building.
Why It Matters
Even a small drop in savings rate after a raise can mean thousands less saved per year. Over decades, that compounds into a much smaller nest egg. Resisting lifestyle inflation—keeping spending flat and saving the raise—dramatically accelerates wealth building.
Who Is Affected
Anyone whose spending rises with income: bigger apartment after a raise, new car when salary increases, more dining out. The calculator compares your income and savings rate before vs after a raise to show the increase in spending and the savings sacrificed.
How It Is Calculated
Spending = Income × (1 − Savings Rate). Lifestyle inflation (dollars per year) = Spending after − Spending before. Savings sacrificed = Income after × (Rate before − Rate after): how much more you would save per year if you kept the old rate on the new income.
The Formula
Spending = Income × (1 − Savings Rate)
Savings Sacrificed = Income After × (Rate Before − Rate After)
How to Avoid It
When you get a raise, keep spending the same and save the difference. Automate the increase: raise your 401(k) or direct deposit to savings by the amount of the raise (after tax). If you never see the extra money in checking, you are less likely to spend it.
Save the Raise
Commit to saving 50–100% of each raise. That way your savings rate rises over time and lifestyle inflation is minimized. You can still allow some spending increase, but the majority of the raise goes to savings.
Track Spending
Track spending before and after raises. If spending rises in lockstep with income, you are inflating lifestyle. Aim to keep spending flat or growing more slowly than income so your savings rate climbs.
Using This Calculator
Enter annual income and savings rate before the raise, then annual income and savings rate after the raise. The calculator shows spending before/after, lifestyle inflation (increase in spending), and savings sacrificed (how much more you could save per year with the old rate on the new income).
What Counts as Savings Rate
Savings rate = savings ÷ income (before or after tax, but be consistent). Include 401(k), IRA, taxable savings, and other investments. Exclude one-off windfalls; use ongoing monthly or annual savings and income.
Conclusion
Lifestyle inflation slows wealth building by increasing spending when income rises. Use this calculator to see how much more you spend after a raise and how much you could save by keeping your old savings rate. Resist lifestyle creep by saving the raise and keeping spending flat.
Frequently Asked Questions
Common questions about lifestyle inflation
What is lifestyle inflation?
Lifestyle inflation (lifestyle creep) is when you spend more as your income rises instead of saving the raise. Your savings rate drops on a higher income, so you build wealth more slowly. Resisting it means keeping spending flat and saving the raise.
What is “savings sacrificed”?
It is how much more you would save per year if you kept your old savings rate on your new income. Formula: Income after × (Rate before − Rate after). It shows the opportunity cost of lowering your savings rate after a raise.
Should I use gross or net income?
Use the same basis for both before and after (e.g. gross or take-home). Savings rate = savings ÷ income. If you use take-home income, use take-home-based savings (after tax); if gross, include pre-tax 401(k) and gross income.
How do I avoid lifestyle inflation?
When you get a raise, save the difference: increase 401(k), IRA, or direct deposit to savings by the amount of the raise (after tax). Automate it so the extra money never hits checking. Commit to saving 50–100% of each raise.
What if my savings rate went up after the raise?
If you entered a higher savings rate after the raise, “savings sacrificed” will be negative—meaning you are saving more per year than if you had kept the old rate. That is the opposite of lifestyle inflation and accelerates wealth building.
How much of a raise should I save?
A common rule is to save 50–100% of each raise. If you save 100%, your spending stays flat and your savings rate rises. Saving 50% still improves the rate while allowing some lifestyle increase. The calculator shows the cost of saving less.
Does lifestyle inflation affect retirement?
Yes. If spending rises with every raise, you need a larger nest egg to maintain that spending in retirement. Resisting lifestyle inflation means a higher savings rate over time and a lower retirement spending target, so you need less to retire.
What if my “after” income is lower (job change, part-time)?
You can still use the calculator: enter the higher income as “before” and the lower as “after.” If your savings rate stays the same or rises, you are cutting spending rather than inflating lifestyle—which is the right response to lower income.
How do I track savings rate over time?
Savings rate = savings ÷ income (both annual or both monthly; be consistent). Track in a spreadsheet or budget app: each month or year, sum savings (401(k), IRA, taxable, etc.) and divide by income. After each raise, compare new rate to old to see if you inflated lifestyle.
What counts as “savings” for the savings rate?
Include 401(k), IRA, HSA, taxable brokerage, and savings account contributions—anything that increases net worth rather than spending. Use the same definition for before and after so the comparison is fair. Employer match can be included in both savings and income if you want to reflect total compensation.
Usage of this Calculator
Practical applications and real-world context
Who Should Use This Calculator?
Anyone Who Got a RaiseTo see how much extra spending (lifestyle inflation) you have and how much you could save by keeping your old savings rate.
Planners and BudgetersTo quantify the cost of a lower savings rate after income increases and to plan “save the raise” strategy.
High Earners & Career ClimbersTo avoid spending every raise and to keep savings rate high as income grows for faster wealth building.
Retirement SaversTo see how lifestyle inflation reduces annual savings and extends years to retirement or lowers retirement income.
Limitations & Accuracy nuances
Consistent basis: Use the same income and savings definition for before and after (e.g. gross vs net, monthly vs annual).
One raise: Calculator compares one “before” and one “after” snapshot. For multiple raises, re-run with new before = old after.
No investment growth: “Savings sacrificed” is contributions only; compound growth over time would increase the gap further.
Real-World Examples
Case A: $60k at 20% savings → $75k at 15% savings
Spending before $48k, after $63.75k. Lifestyle inflation $15,750/yr. Savings sacrificed = $75k × (20% − 15%) = $3,750/yr. Keeping 20% on $75k would save $15k/yr (vs $11.25k at 15%).
Case B: $50k at 10% → $65k at 20% (save the raise)
Savings rate increased. Spending before $45k, after $52k. Savings sacrificed is negative: you are saving $6,500 more per year than if you had kept 10% on $65k. You saved the raise and more.
Summary
The Lifestyle Inflation Calculator compares income and savings rate before vs after a raise. It shows spending before/after, lifestyle inflation (increase in spending), and savings sacrificed (how much more you could save per year with your old rate on the new income).
Resist lifestyle creep by saving the raise and keeping spending flat.
