FAQ
Use conservative assumptions. Many people test a few scenarios (e.g. 4%, 6%, 8%) rather than relying on one number.

Yes. More frequent contributions can increase final value slightly by investing earlier.
For long horizons, yes—otherwise future dollars may look larger than their real purchasing power.
No. This is a simplified constant-rate projection.
