The Snowball is expected to receive income in excess of £10k next year.

But for comparison purposes let’s use 10k. If you can compound your income at 7% pa you should double your income in ten years, if you cannot compound at 7%, you will still double your income but it will take longer to reach 20k of income.

The Snowball uses a comparative share VWRP and the current value is £151,533.00

Using the 4% rule to achieve a income of 20k, your fund would have to be valued in ten years time at £500k and as it is recommended to have a cash buffer of 3 years when you start to withdraw income from you fund it would need to be valued at 560k. Good luck with that. As you can see from the graph you will have many years of your fund not increasing in value but trending sideways after periods of strong gains.
