About this inflation calculator
See what an amount of money today is equivalent to after a number of years of inflation, using a constant assumed annual inflation rate. Enter today's amount, an annual inflation rate, and a number of years, and this tool compounds that rate forward to show the future amount you would need to have the same purchasing power, along with how much purchasing power is lost in nominal terms. Use this workspace to prepare a result you can review before putting it to use. All processing takes place on your device, without an account or an upload of your inputs. Check the examples to understand the expected output, read the limitations for the supported scope, and reset the form when you want to start a separate task.
How it works
Future equivalent value = amount × (1 + annual rate / 100) ^ years, the standard compound-growth formula applied to a constant inflation rate.
Try these examples
$1,000 today; 6% annual inflation; 10 years
$1,790.85 future equivalent value
Same inputs
$790.85 purchasing power lost
Limitations & privacy
