Retirement age

Simulated using 10,000 Monte Carlo paths bootstrapped from this portfolio's historical monthly returns, and adjusted for 2% annual inflation. Contributions continue at £500/month for the whole projection, including past your target retirement age, and are not increased with inflation. Nothing is withdrawn, so this shows when you reach your number, not how long it lasts afterwards. Figures are gross of tax and shown in the portfolio's base currency (GBP). Past performance does not guarantee future results. This is not financial advice.
