Both interactive investor and IG are investment platforms that offer both share dealing and ready made portfolios. This means that they’ve both got offerings suitable for both beginner and intermediate investors. IG also offers riskier contracts for difference (CFDs), but as interactive investor doesn’t offer these, we won’t be comparing this feature.
Both providers have very similar offerings, with individual savings accounts (ISAs), self-invested personal pensions (SIPPs) and general investment accounts.
The main difference between the two is the cost structures, detailed below.

This doesn’t pay out if your investments don’t perform well.
Having axed its trading commissions, IG wins hands down on costs. Note that it does charge an inactivity fee after a year without trades.

IG previously waived trade fees if you placed enough trades per quarter. Now though, it’s done away with them altogether. interactive investor charges a flat monthly fee. Interactive investor has the lower minimum deposit here, requiring you to only invest £1.
We’ll compare the fees in two parts: ready made portfolios and share dealing.
IG’s fees are pretty simple. For its “smart portfolio”, it charges 0.72% on investments up to £50,000 made up of a 0.50% IG management fee, an average of 0.15% in fund costs and 0.07% for transaction costs. For investments over £50,000 it charges 0.22%, made up of an average of 0.15% in fund costs and 0.07% in transaction costs. You pay no IG management fee over £50,000.
interactive investor has a flat fee for using all of its services (an additional fee applies if you want to add the self-invested personal pension). Its most basic plan “Investor” costs £9.99 per month.
What does that actually mean?
If you invest £10,000 with IG, then you’ll spend £72 (in a year).
If you invest £10,000 with interactive investor then you’ll spend £119.88 (in a year).
Many investment platforms have calculators that help you work out the costs of your investments based on a figure you enter. Neither IG nor interactive investor has this, so we did it the old fashioned way, with a calculator, pen and paper using the costs outlined above.
IG has now axed its share dealing fee, so this one’s simple.

Both IG and interactive investor have a great range of learning resources to help you learn about investing. You can view guides, watch videos and use both platforms’ demo accounts – good if you want to learn how to invest, but also to help you decide if you like the provider.
IG’s main advantage is “IG Academy”, its dedicated learning tools. You can follow a set course with videos and quizzes in its dedicated app.
Winner: IG
IG comes out comfortably on top. These platforms are, on the face of it, very similar. But axing its share dealing fee has meant IG takes home the trophy. However, with interactive investor if you plan to open several different trading accounts (such as a JISA, an ISA and a general investment account), you can open as many as you want for your one flat fee.
IG’s learning resources are a lot better than interactive investor’s, and it’s better for ready made portfolios.
