I have recently opened JISA's for my dc and I'm trying to imagine how much that would look like when they are 18. I appreciate I could just calculate the amount paid in and add a bit of interest to get a figure but I can't really wrap my head round the value of money in 10 to 15 years time. So, if you've been paying into your child's JISA and they are now sort of 16 to 18 years old, please tell me how much they have now? If you can also mention how much you were paying monthly over the years that would be very helpful. Thanks in advance x
