よくある質問

Is this a substitute for a financial planner?

No - it's a planning tool. Real retirement planning involves taxes, healthcare, Social Security, pensions, and portfolio glide paths that this simple model doesn't cover. Consult a qualified financial planner.

Why is post-retirement return usually lower?

Most retirees shift toward more conservative, income-oriented investments (bonds, dividend stocks) with lower expected returns.

What's the "4% rule"?

A rule of thumb suggesting you can withdraw 4% of your nest egg in year one and adjust for inflation thereafter with a high chance the money lasts 30 years. This tool computes the withdrawal that exactly depletes the balance.
