Pay raise vs inflation: did purchasing power increase?
2026-07-19
A bigger number on the offer letter is nominal. To test purchasing power, align one pay period with one official CPI comparison and compound the two rates.
Direct answer
A raise beats inflation only when (1 + raise rate) ÷ (1 + inflation rate) − 1 is positive. A $70,000 salary with a 4% raise becomes $72,800, but with 5% inflation its real change is 1.04÷1.05−1 = −0.95%; the new salary buys about what $69,333.33 bought before. Subtracting 5% from 4% gives a useful shortcut, but the ratio is the exact compounded result.
Inputs to collect
- Old gross pay for one consistent annual, monthly or hourly period
- Nominal raise percentage, excluding bonuses unless they recur
- Official CPI change for the same start and end periods
- Whether the CPI is annual average, year-over-year month or another index comparison
- Base pay, hours and benefits that changed alongside the raise
- Take-home impact if taxes, deductions or contributions changed
- Personal spending categories that materially differ from the CPI basket
Formula
New nominal pay = old pay × (1 + raise%). Exact real change = [(1 + raise%) ÷ (1 + inflation%) − 1] × 100. New pay in old-period dollars = new nominal pay ÷ (1 + inflation%).
Worked example
$70,000 × 1.04 = $72,800 nominal. Real change = (1.04÷1.05−1)×100 = −0.95%. Purchasing-power equivalent = $72,800÷1.05 = $69,333.33 in old-period dollars, so the raise did not preserve purchasing power in this scenario.
Sensitivity check
| Scenario | Changed input | Result |
|---|---|---|
| Raise equals inflation | 5% raise; 5% inflation | 0.00% real change; $70,000 old-dollar equivalent |
| Raise 6%, inflation 5% | Raise becomes 6% | +0.95% real; $70,666.67 equivalent |
| Inflation only 3% | Inflation becomes 3% | +0.97% real; $70,679.61 equivalent |
| No raise, inflation 5% | Raise becomes 0% | −4.76% real; $66,666.67 equivalent |
Compare your raise with matching CPI
Limitations
- Use CPI observations with the same time boundary as the raise; do not mix a monthly change with an annual raise.
- BLS annual calculator values use calendar-year averages, while the current year uses the latest monthly index, so record the exact method and retrieval date.
- CPI describes an average urban consumer basket, not your personal cost-of-living change.
- This gross-pay comparison excludes taxes, benefits, hours, bonuses and promotion risk unless you analyze them separately.

Match BLS periods before calculating
The BLS calculator uses calendar-year average CPI for completed years and the latest monthly index for the current year. If your raise begins in a particular month, obtain the CPI change for matching months instead of mixing it with an annual average.
Keep compensation outside the CPI formula visible
A promotion can change hours, bonus eligibility, health premiums, retirement match or tax withholding. The real-raise result answers one narrow question about gross base pay; it does not settle total compensation.
