Frequently Asked Questions
How accurate are these projections?
Investment projections assume a constant return rate which never occurs in practice. Use these as planning guides, not guarantees.
Should I consult a financial advisor?
For retirement planning, a fee-only fiduciary financial advisor can provide personalised guidance accounting for your full financial picture.
