Frequently asked questions

What return should I assume?
This is a projection, not a guarantee. A broad stock market long-run average is often cited around 7% after inflation, but real returns vary widely year to year.
Does it account for taxes or fees?
No — it's a clean growth projection. Fees quietly erode returns; the MER Fee Drag calculator shows how much.
