Salary Inflation Calculator

See what your salary is really worth after inflation — compare your pay today against any past year, measure cumulative purchasing-power loss, and compute the salary you'd need now to match what you earned then.
Quick answer: Inflation-adjusted value = past salary × (current CPI ÷ past CPI). A $70,000 salary from 3 years ago needs roughly $77,000-80,000 today (at 3-4% average inflation) to buy the same life. Earning the same nominal salary means a ~10% real pay cut.
The Formula
Inflation-adjusted salary = Past Salary × (1 + inflation rate)years
Or with CPI index values: Past Salary × (CPI now ÷ CPI then). The compounding is what people underestimate — 3.5% inflation doesn't cost 10.5% over three years; it costs 10.87%, and the gap widens every year you're not adjusted.
Worked Examples
Example 1 — the stagnant salary. $70,000 three years ago at 3.5% average inflation needs $70,000 × 1.035³ = $77,614 today. Still earning $70,000? You took a 9.8% real pay cut without a single conversation about it.
Example 2 — the deceptive raise path. $70,000 with 2% annual raises over 3 years lands at $74,285 — against the $77,614 target, still $3,300/year behind. Raises below inflation are decay with better optics; check any single year's raise with the COLA calculator.
Example 3 — the long view. A $50,000 salary from 10 years ago at ~3% average inflation ≈ $67,200 today. Job-tenure loyalty without inflation adjustments has a precise, calculable price — and it explains most of the job-switcher pay premium.
Real vs Nominal: The Only Distinction That Matters
| Term | Meaning |
|---|---|
| Nominal salary | The number on your offer letter |
| Real salary | What it buys — nominal deflated by CPI |
| Real raise | Nominal raise − inflation (routinely negative in hot years) |
| Purchasing-power gap | Inflation-adjusted old salary − current salary |
Using This in a Negotiation
- Compute your gap since your last real adjustment — "adjusted for inflation, my compensation has declined $6,400" is arithmetic, not opinion.
- Separate restoration from merit: ask for the inflation catch-up as baseline correction, then negotiate merit on top — bundling lets employers pay one number and call it both. The paycheck impact of the combined ask: pay raise calculator.
- Benchmark externally too: market rates for your role may have moved more than CPI — inflation adjustment is the floor of your case, not the ceiling.
Which Inflation Rate To Plug In
US long-run average: ~3%; the 2021-2023 spike pushed multi-year averages above 4-5% for windows that include it. For precision, use actual CPI-U index values for your two dates (BLS publishes them monthly) rather than a flat average. UK users: substitute CPI/CPIH from the ONS; India: CPI from MOSPI — the formula is identical everywhere.
Salary Inflation vs Wage Growth (The Macro Context)
Economy-wide wage growth and CPI chase each other: in loose labor markets, wages lag inflation (workers lose ground); in tight ones, job-switchers capture premiums 2-3 points above stayers. That switcher-stayer gap is the empirical version of this page's math — employers reprice for new hires faster than for incumbents, which is why running your own numbers annually (and occasionally against other metros) is basic career hygiene.
Frequently Asked Questions
How do I calculate what my salary is worth after inflation?
Past salary × (1 + inflation)^years gives today's equivalent. $70,000 from 3 years ago at 3.5% needs ~$77,600 now for equal purchasing power.
What is a real vs nominal salary?
Nominal is the dollar figure; real is its purchasing power after CPI. Real raise = nominal raise minus inflation — often negative in high-inflation years.
My salary has not changed in 3 years — how much have I lost?
At ~3.5% average inflation, about 10% of purchasing power. The calculator gives your exact gap to use in a negotiation.
What inflation rate should I use?
Actual CPI values for your dates are most precise (BLS for US, ONS for UK, MOSPI for India). As a flat average, ~3% long-run US; higher for windows including 2021-2023.
Why do job switchers out-earn stayers?
Employers reprice roles to market for new hires faster than they adjust incumbents — switchers capture the inflation catch-up stayers have to negotiate for.
How do I use this in a raise conversation?
Present the computed purchasing-power gap as baseline restoration, separate from merit — arithmetic framing ("my pay has declined $X in real terms") is hard to argue with.
