This quick, free calculator can show you whether you’re on track for retirement. By evaluating the percentage of income that needs to be replaced at the start of retirement and the estimated growth of income and investments, the calculator will determine whether your current savings are likely to be sufficient to support the typical 4% initial withdrawal from savings at the start of retirement (i.e., the 4% Rule). Retirement income replacement and the 4% Rule are covered in “What Would Dad Do? Volume 2 - The Middle Years” and Volume 3 - The Later Years.

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