Looks positive until compared against inflation.
Can turn a 4% raise into a real pay cut.
Raise percentage minus inflation rate, in this example.
Separate the Nominal Number From the Real One
Charlie Munger's published mental-models approach argued for combining multiple lenses rather than trusting a single, isolated number, and a mental model for judging whether a raise actually beats inflation applies that discipline by subtracting inflation from the raise percentage before calling it a gain. For example, consider an employee who received a 4% raise, celebrated as a solid increase, during a period when inflation ran at 5%. In nominal dollars, a $60,000 salary became $62,400. In real purchasing power, that same household could afford roughly 1% less than the year before, a genuine decline masked by a paycheck number that went up. Per the USC archive of Munger's psychology speech, evaluating a number through more than one lens, nominal and real, was treated as essential to avoiding a common misjudgment. As of July 2026, this is especially important if you're budgeting increased spending based on a raise percentage without checking the same period's inflation rate.
Nominal salary rose. Real purchasing power fell by roughly the difference.
Run the Subtraction Before You Spend
Per the Berkshire Hathaway letter archive, evaluating a number relative to its real, purchasing-power-adjusted value, not its headline figure, is a recurring theme in Munger and Buffett's published shareholder communications. Comparing your raise against the national inflation rate, and against an FDIC-insured savings benchmark like 0.38% APY, keeps both sides of your finances honest.
| Scenario | Real change in purchasing power | Next check |
|---|---|---|
| 4% raise, 2% inflation | Genuine real gain of about 2% | Budget increased spending with confidence |
| 4% raise, 5% inflation | Real decline of about 1% | Avoid increasing spending based on the nominal number |
| No raise, 3% inflation | Real decline of about 3% | Prioritize a real-return review, per Federal Reserve inflation context |
| Raise matches inflation exactly | Purchasing power roughly flat | Treat as maintaining, not gaining, ground |
Calculating your real raise has real benefits: it prevents overspending based on a number that doesn't reflect actual purchasing power. The risk of trusting the nominal percentage alone, as the 4%-raise example shows, is a real, if easily missed, decline in what your paycheck can actually buy. However, that said, it depends on the specific inflation rate compared to your raise percentage: a raise well above inflation is a genuine gain worth budgeting against, while one below it is not, regardless of how positive the nominal number looks. If you're deciding whether to increase discretionary spending after a raise, choose to increase it if your raise genuinely exceeds the period's inflation rate; choose to hold spending flat if it doesn't. This is when this matters most: immediately after any raise or cost-of-living adjustment, before spending decisions are made based on the nominal number alone.
The real, not nominal, number is what matters for spending decisions.
Use inflation data covering the same period as your raise.
It can be a real decline dressed up as a positive nominal number.
Both raises and inflation change; recalculate each cycle.
When This May Not Apply
During periods of very low inflation, a modest raise is more reliably a genuine real gain, and the subtraction matters less. This is especially important to reassess during periods of elevated inflation, when the gap between nominal and real can be substantial.
