Pete and Eliza decide to start saving early for their newborn son Ben, so they open a Junior ISA and invest £250 per month into a managed portfolio of investment funds.
Over the next 10 years, they invest a total of £30,000 into Ben’s JISA. While markets go up and down, the portfolio grows at an average rate of 5% each year.
When Ben is 10 they stop making contributions but keep the portfolio invested. It continues to grow at 5% each year. By the time Ben is 20, he has an ISA portfolio worth £64,204.
