Run these three scenarios
1. Your current reality. Enter actual portfolio size, contribution, and time.
2. Your current reality plus more capital. Raise the monthly contribution and see what changes.
3. Your current reality plus better competence. Keep the contribution the same and raise the return assumption.
A few extra points of return do not sound like much. Over ten or fifteen years they can mean hundreds of thousands of dollars.
