ISA Costcustody plus dealing, not the headline rate

AJ Bell: what the ISA actually costs

AJ Bell is not the cheapest at any pot size on this site. That is not a verdict on the platform — only on its published charges against the others', at 12 trades a year.

Above £250,000 AJ Bell's fund charge tapers to nothing by £500,000, but the intermediate rates are not published on the page this was read from, so fund pots above £250,000 are left uncosted.

Every figure assumes 12 trades a year of £1,000 each, inside a stocks and shares ISA. It excludes Stamp duty at 0.5% on UK share purchases, the £1 PTM levy on orders over £10,000, fund manager charges (the OCF), and any foreign-exchange fee — every one of those is charged by someone other than the platform and is the same wherever you hold the money.
