Inflation Erosion Calculator runs a dedicated pure TypeScript formula module for this tool, then formats the output for the calculator page.
- 1
Read fields
The form reads Amount today, Annual inflation rate, and Years and applies the displayed defaults only when a value is missing.
- 2
Normalize values
Numeric inputs, dates, select choices, percentages, and minimum limits are normalized before calculation.
- 3
Apply equation
The primary equation is future purchasing power = amount / (1 + inflation)^years.
- 4
Build metrics
The calculator builds result cards for Future purchasing power, Purchasing power lost, and Loss percentage from the formula output.
- 5
Prepare details
Supporting rows, charts, schedules, or export rows are prepared when they help explain the answer.
- 6
Format results
Currency, percentages, dates, decimal places, and labels are formatted for readability before display.
Inflation Erosion Calculator shows the main mathematical equation first, followed only by the variables used in that equation.
Y = x / (1 + r)^tFuture Purchasing Power
The ending value solved by the equation after the rate, time, and adjustment variables are applied.
Amount
An amount or adjustment included in the equation total.
Inflation
The proportional factor used by the formula; percentage values are converted to decimals before calculation.
Years
The duration used by the formula, expressed in the time unit required by the equation.
