CMC Invest has cut the cost of its Plus and Premium plans, making its self-invested personal pension (Sipp) cheaper by nearly £170 a year.

A Sipp from CMC Invest is only available on its Premium tier, which previously cost £25 a month and is now £10.99 a month.

The price drop makes CMC Invest* much more competitive with other flat-fee investment platforms, including Interactive Investor and Freetrade.

CMC Invest is an upstart investment platform, launching in 2022 amid surging appetite for low-cost providers such as Trading 212 and eToro.

But it's not completely unknown – the platform is backed by the well-established CMC Markets, operating since 1989.

Although platforms with zero account fees have grown in popularity in recent years, they don’t all offer Sipps. Find out how CMC Invest compares with other providers below.

Investing platforms: Newer providers have surged in popularity

	Core	Plus	Premium
Cost	Free	£6.99 a month (was £10)	£10.99 a month (was £25)
Accounts available	Cash Isa, general investment account	Cash Isa, stocks and shares Isa, general investment account	Cash Isa, stocks and shares Isa, Sipp, general investment account

FX fee	0.99%	0.5%	0.39%
Global stocks and ETFs (US, UK and European)	4,600+	6,100+	6,100+

Here’s how much other flat-fee investment platforms charge for their Sipp:

Freetrade*: £9.99 a month billed annually or £11.99 when you pay monthly.

Interactive Investor*: £5.99 a month when investing up to £50,000, or £12.99 a month above £50,000. For both an Isa and a Sipp, it costs £9.99 a month up to £75,000 and £21.99 a month above that amount.

But even cheaper investing can be found at Prosper* which is offering no Sipp account fees for ten years to those who open one before 1 September

CMC Invest's fees were previously on the higher side. Even though it offered a free three months of Plus and a free 12 months of Premium, there were much cheaper options available over the longer term.

The new plans make it worth considering alongside other flat-fee platforms, especially if you want to open or transfer a pension.

Flat fees usually work out better for those with larger portfolios. Unlike platforms that charge a percentage of the value of your investments, flat fees mean you know what you'll be charged whether you have £5,000 or £50,000 in your account.

Freetrade* beats CMC Invest* if you pay annually, but CMC Invest works out cheaper monthly.

CMC Invest also has around 1,000 mutual funds available for both Plus and Premium subscribers – Freetrade has a small selection of 22 available currently, only for those on its most expensive tier.

Other platforms such as InvestEngine*, Trading 212 and Prosper* don’t have account fees at all, but your investment choice is generally more restricted.

Trading 212 also doesn't currently offer a Sipp.

IWeb doesn't charge an account fee, but it isn't currently accepting applications for new Sipps and it charges £5 a trade.

When choosing an investment platform, you should think beyond fees - cheapest won't necessarily be the best for you. Think carefully about the type of investor you are, including what you want to invest in and how much support you need.

Investing online is simple, cheap and can be done from your computer, tablet or phone at a time and place that suits you.

When it comes to choosing a DIY investing platform, stocks & shares Isa, self invested personal pension, or a general investing account, the range of options might seem overwhelming.
