We know that everything gets more expensive over time due to inflation. Even low levels of inflation can increase any expense by 20%, 30%, or more over ten years. When planning future budgets, it can be helpful to project how expenses will increase over time. This free Expense Inflation Calculator lets you enter a current expense and the estimated inflation rate to see how the expense might increase each year. The impact of inflation is covered in “What Would Dad Do? Volume 1 - The Early Years,” “Volume 2 - The Middle Years,” and “Volume 3 - The Later Years.” This spreadsheet is also included in the Retirement Yearly Plan spreadsheet.

Requires the Excel, LibreOffice, or OpenOffice application. The spreadsheet-formatted files are provided at the download link emailed after checkout.
