Various comparison sites recommend Moneybox as the top Cash Lifetime ISA, but its headline rate drops by 1% at the end of the first year. My son has had his account for 3 years, so he's been getting the lower interest rate for 2 years, currently 4% but variable.
He has around £15k in the account (including £3k Government bonus).
He is likely to want to buy within the next 1-5 years, so a Stocks & Shares ISA may be risky. Nevertheless, I'm thinking of suggesting he transfers the account to Dodl, which is a S&S ISA with 5.09% interest on funds left in cash. It has an annual 0.15% fee. So would I be right in thinking he would get an equivalent interest rate of 5.09 - 0.15 = 4.94%?
Or am I missing something?
