Teaching & troubleshooting tips

Can I change the assumed return?

Yes. Switch the risk profile to conservative, balanced, or growth to adjust the underlying annual return assumption (5%, 7%, or 9%).

Does this include taxes or employer matches?

No. The projection is pre-tax and does not account for employer contributions. Add matching funds to the monthly contribution to include them.
