Use this US inflation calculator to estimate how much a dollar amount from one year would be worth in another year using a CPI-based inflation adjustment. It is useful for comparing salaries, prices, savings, allowances, rents, and historical costs across different periods in the United States.
If you only need the raw percentage change itself, our Percentage Calculator is a good companion.

What this calculator helps you do
Inflation changes what money can buy over time. A number from 1985 or 2005 does not mean much on its own unless you compare it against the cost of living in another year.
This calculator is useful if you want to:
- compare an old salary with a current one
- see what a historical price would represent today
- adjust savings, allowances, or budgets for inflation
- add context to news, family stories, schoolwork, or historical research
How this US inflation calculator works
This tool applies a CPI-style inflation adjustment to estimate equivalent purchasing power between two years in the United States.
What it does
- compares a dollar amount between two years
- estimates the change in purchasing power over time
- helps you contextualize prices, wages, and household costs
- gives a practical inflation-adjusted reference instead of a raw historical number
What it does not do
- it does not replace financial, legal, tax, or investment advice
- it does not predict future inflation
- it does not capture every personal or regional cost difference
- it should not be treated as an exact accounting figure for formal administrative use
Worked examples
1) $20 in 1990
A small amount from decades ago can still tell an interesting story. Adjusting $20 from 1990 helps show how everyday purchases changed over time.
2) $1,000 in 2000
This is a useful benchmark for comparing savings, wages, and routine household costs across the early 2000s and today.
3) A past salary
If you know what someone earned years ago, you can use this calculator to estimate what that income represented in current-dollar terms.
4) Rent, groceries, or car costs
You can also use inflation-adjusted comparisons to make old rent, food, fuel, or car-price examples much easier to understand.
FAQ
What data does this calculator use?
It uses CPI-based inflation logic to compare the value of money across years in the United States.
Can I use it for salaries, prices, and allowances?
Yes. It is useful for wages, household budgets, product prices, historical comparisons, and general purchasing-power context.
Does it only show the adjusted amount?
No. The real point is to help you interpret what the number meant in practical terms, not just display a converted value.
Is this the same as a simple percentage calculator?
No. A percentage calculator measures change directly, while an inflation calculator tries to estimate equivalent purchasing power between years.
