Most inflation tools answer a simple question: what did a dollar in 1985 buy in today’s money? That’s useful, but it’s not the question that matters when you’re negotiating a raise or comparing offers across years. The question that matters is: what do I need to earn now to keep the lifestyle I had then?
This calculator answers that one. It ships with more than a century of US Consumer Price Index data from the Bureau of Labor Statistics and extends the series forward with projected estimates for 2025 and 2026. Two years of projections are marked clearly so you know which figures are official and which are estimates. Everything else runs on real, published CPI values.
Select your currency from the dropdown.
Choose US historical data or custom rate.
Pick yearly or quarterly frequency. Yearly matches the CPI annual average. Quarterly compounds the rate in four steps per year.
Enter the salary you want to adjust.
Set the starting year.
Set the target year. It must be after the starting year.
Read the required salary from the hero result.
Check the scenario table for alternative inflation rates.
With US historical data, the calculator divides the target year’s CPI by the starting year’s CPI. That ratio is the inflation factor. Multiply the old salary by the factor to get the required salary.
Formula: Required Salary = Old Salary × (CPI Target Year ÷ CPI Starting Year)
With custom data, it compounds your rate forward. A 3% annual rate over ten years produces a factor of 1.03^10 = 1.344. Multiply the old salary by that to preserve buying power.
Formula: Required Salary = Old Salary × (1 + Rate ÷ 100)^Years
Annualised rate is derived from the total factor. Take the Nth root, subtract one, multiply by 100. If you want to hit a specific future salary, enter it as the target and the tool works backwards to show what average rate would get you there.
Years 2025 and 2026 use projected CPI estimates, not official BLS figures. The calculator labels them clearly in the year dropdown and in the projection table.
A graphic designer earned $44,000 in 2018. She’s negotiating a new role in 2026 and wants to know what salary preserves her 2018 standard of living.
CPI in 2018: 251.107. CPI in 2026 (projected): 331.000.
Inflation factor: 331.000 ÷ 251.107 = 1.318.
Required salary: $44,000 × 1.318 = $57,992.
Annualised inflation over those eight years: roughly 3.52% per year.
A $58,000 offer in 2026 preserves her 2018 buying power. Below that, she’s taking a real pay cut even if the nominal number looks bigger. The scenario table shows what a 2% rate environment would imply instead: about $51,500. The gap between 2% and 3.52% compounds to $6,500 over eight years.
Multiply your old salary by the ratio of the target year’s CPI to the starting year’s CPI. A $40,000 salary in 2010 becomes roughly $57,500 in 2024, since the CPI rose about 44% over that span.
Most central banks target 2% annually. Between 2% and 3% is the healthy zone. Below 1% risks deflation. Above 5% starts to erode real incomes quickly.
Inflation reduces the buying power of a fixed salary. A salary that doesn’t rise with inflation means you can buy less each year even though the nominal number hasn’t changed.
CPI is an index that measures price levels. Inflation is the rate of change in that index. CPI tells you the level today relative to a base period. Inflation tells you how fast prices moved over a specific period.
The Bureau of Labor Statistics publishes official annual CPI averages after the year ends. The calculator includes projected estimates for 2025 and 2026, labelled clearly in the dropdown and the projection table. These are estimates, not official figures.
CPI is a national average based on a fixed basket. Your spending mix may differ. If you spend more on housing, healthcare, or education than average, your personal inflation rate could be higher.
Multiply your current salary by the cumulative inflation factor between now and the target year. At 3% annual inflation over five years, the factor is 1.159, so a $60,000 salary needs to reach about $69,500.
Yes. Negative inflation is deflation. It’s rare and usually signals weak demand or recession. Prices fall, and fixed salaries gain buying power without any raise.
