About Inflation Calculator
Use Inflation Calculator locally with your own assumptions. This is an estimate, not financial advice.
Does this tool send my data anywhere?
No. Its calculation or transformation happens on your device.
Using Inflation Calculator with the right inputs
Estimate inflation-adjusted purchasing power using a chosen rate. Start by matching your task to the quantities and options shown below. The definitions of the inputs matter as much as the final number or transformed output; retain the original values so that you can repeat or check the result.
Inputs and options explained
- Current value: Use the amount for the period indicated and keep the currency consistent with other money inputs. The form indicates a minimum of 0.
- Annual inflation (%): Enter the percentage in the scale shown by the label; for a field marked %, enter 5 for five percent rather than 0.05. The form indicates a minimum of 0.
- Years: Enter the numeric value for this quantity using the units or scale shown in the label. The form indicates a minimum of 0.
Example to try in this tool
Use the following sample values to see how the controls and result fit together. They are an illustration of the operation, not recommended values for your own situation.
- Current value: 100
- Annual inflation (%): 10
- Years: 2
Select Calculate. The result begins with:
Inflation-adjusted value
82.64
Purchasing-power estimate using a constant annual rate.
This example records the tool’s output for those inputs. Check the method and assumptions against your own task before using a result; reproducing an example is not independent certification of the underlying model.
Interpretation and limitations
Use one currency and a consistent time period for related inputs. Separate assumed rates from charges or conditions that actually apply to your account. A scenario calculation cannot establish eligibility, predict future returns or replace the terms of a financial agreement.
Is the output a financial recommendation?
No. It is a calculation from the supplied assumptions. Compare it with your records and actual provider terms, and seek qualified advice when a decision materially affects your finances.
Before you use the output
- Choose the intended action: Calculate. Re-run the operation after changing an input or mode so that you are checking the updated result.
- Read the result label and any accompanying explanation. Keep the input values or source file with the output so that a later comparison uses the same assumptions.
- If a result looks unexpected, check units, separators and selected options first. Try a smaller example you can verify rather than repeatedly changing several settings at once.
Questions or a result that needs checking?
If you find a discrepancy, report a problem with Inflation Calculator. Include a non-sensitive example, the selected options, the result you expected and the result shown. This makes the issue easier to reproduce. See About & privacy for how the site handles tool inputs.
