When a 5% assumption is useful

A 5% annual return is often used as a conservative planning number. It can help you stress-test a goal without relying on aggressive assumptions that make the final balance look better than reality.

How to read the result

  • Treat the final value as an estimate, not a promise.
  • Use the year-by-year table to see whether your contribution level is doing enough work.
  • Compare this page with a 7% version to see how sensitive your plan is to return assumptions.
