Frequently Asked Questions

A retirement gap is the shortfall between your projected retirement income (from savings, Social Security, pensions, and other sources) and your desired retirement income. Closing this gap requires additional savings or adjustments.

The calculator shows the required corpus to produce your desired income using the 4% rule, and how much additional savings you need to accumulate. You can close the gap by saving more, working longer, or reducing desired income.

A surplus means you are on track or ahead of your retirement goal. Consider whether you can retire earlier, increase your desired income, or leave a larger legacy. Review your plan periodically to stay on track.
