Frequently Asked Questions
Pro Tips
The difference between starting at 25 vs 35 with the same monthly contribution is not 10 years — it's often double the final balance. The first decade of compounding is the most powerful.
If your employer matches 401k contributions, that's a guaranteed 50–100% return on that money before it even invests. Never leave employer match unclaimed.
Use a 3% withdrawal rate instead of 4% if you plan to retire before 60 — a 40-50 year retirement needs more conservative withdrawals to avoid running out of money.
Run this calculator with pessimistic inputs (5% return, 30-year retirement) and optimistic inputs (8%, 20 years). The range tells you how much buffer you need.
