See how inflation reduces the value of money over time.
💸 $1000 today at 3% inflation is worth less each year. In 10 years you'd need $1,344 to buy what $1,000 buys now.
Inflation slowly erodes what your money can buy. This calculator shows how much money you'd need in the future to match today's purchasing power, based on a steady inflation rate.
At 3% annual inflation (roughly the US historical average), prices double every 24 years. That means a $50,000 salary in 2000 has the same buying power as about $94,000 in early 2026. Wages that don't keep up with inflation make you gradually poorer, even if the number stays the same.
A quick mental shortcut: divide 70 by the inflation rate to find the doubling time. At 3.5% inflation, prices double in 70 ÷ 3.5 = 20 years. At 7%, they double in 10 years.
Keeping money in cash means losing ~3% per year to inflation. To preserve purchasing power, you need investments that return more than inflation. The stock market has historically returned ~10% (~7% after inflation), making it a primary inflation hedge for long-term savings.

Calculated results are estimates based on the inputs you provide; actual figures may vary. Always consult a qualified professional before making financial decisions.
The Inflation Calculator lets you figure out inflation calculatorinstantly, without reaching for a spreadsheet or doing the math by hand. Whether you're planning a budget, checking a loan, or working through homework, the tool applies the correct formula behind the scenes and shows the result the moment you enter your numbers.
Unlike a static chart or table, this calculator adapts to your exact inputs. You can adjust any value and see the outcome update in real time, which makes it easy to compare scenarios — for example, "what if the rate were 1% lower?" or "what if I paid an extra $50 a month?"
Common uses: people reach for this tool when they need to find a inflation calculator by year, purchasing power calculator, future value with inflation, or money value past to present.
Browser-based tools like this one have a few real advantages over installed software or manual methods:
The Inflation Calculator is based on the following formula:
Future value = present × (1 + i)^n
Variables: Future value = Cost of the same goods after n years ($) present = Current price or amount ($) i = Annual inflation rate (as a decimal) n = Number of years
Purchasing-power erosion. i = annual inflation rate, n = years. The same money buys proportionally less as prices compound upward over time.
Worked example: Step 1: present = $100, i = 3% = 0.03, n = 10 years. Step 2: (1.03)^10 ≈ 1.3439. Step 3: Future value = 100 × 1.3439 = $134.39. Result: a $100 cart of groceries today will cost about $134.39 in 10 years; equivalently, today's $100 will only buy about $74.41 worth of goods.
