Short answer
£200/month could become roughly £68,000 by 18
Total contributions would be £43,200. With 5% annual growth, a 0.25% annual fee assumption, and no starting balance, the projected Junior ISA value is £68,080 nominally, or about £43,650 in today's money using 2.5% inflation.

The return assumptions are identical. The difference is simply that the child receives twice as much monthly contribution for the full 18 years.
