How should you read this result?

Separate what you actually contribute from the growth created by the assumed return. Treat the return as a scenario, not a promise.

How should you use the result?

Try at least three scenarios: conservative, base, and optimistic. Interest rates, returns, income, and expenses can all change over time.
