Frequently asked questions
What return should I use?
Use a real (after-inflation) return. For diversified stock portfolios, long-run estimates of around 4–7% are common. Savings accounts are lower.
Does this include taxes and fees?
No. Fees and taxes reduce returns, so lowering the rate by 0.5–1% is a sensible stress test.
Is this financial advice?
No. It is an educational estimate. Speak to a qualified adviser for personal advice.
