The following table assumes you start with zero invested in a platform and set up a regular monthly investing plan, making a single investment company purchase each month. The costs shwn are for the first year; in % terms they will typically decrease over time as you hold more assets on the platform. Note that platforms will typically impose a minimum monthly subscription and so some platforms will be excluded from some of the lower monthly payment levels. Also bear in mind that not all platforms offer special rates for regular monthly investing. Where there are no values at all next to a platform, it means that this platform does not offer investment companies. Investment is assumed to be within an ISA.
