Frequently asked questions
How much interest will I earn on settled cash held in my investment accounts?
You can find the most up-to-date interest rate that you’ll earn on uninvested, settled cash balances held in your accounts on our website, or on the wallet screen in the app.
What’s the difference between gross interest and AER?
Gross interest reflects the annual rate earned on settled cash if you withdrew each interest payment after it was received. AER reflects the rate of interest earned each year when payments are not withdrawn from accounts. Due to compounding, it’s a slightly higher rate than gross interest.
When will the amount of interest I’ve earned be calculated?
Interest on uninvested, settled cash will be calculated daily and paid out monthly.
What is settled cash?
Settled cash refers to funds that have been processed, cleared and are available to be withdrawn from your GIA or ISA accounts.
When will I receive my interest payments?
Interest will be paid monthly. You’ll receive a payment within 10 business days from the end of the prior month.
When can I invest interest payments?
Interest payments can be invested as soon as they’re credited to your account.
Will I be taxed on my earned interest?
If your interest is earned in your stocks & shares ISA or your SIPP, you won’t have to pay tax on it. However, tax may be owed on any interest earned within your general investment account, if this exceeds your annual interest allowance. Any interest paid to your general investment account will be shown in your ‘Consolidated Tax Certificate’, provided to you following the end of each tax year. Tax treatment depends on your individual circumstances and may be subject to change in the future.
Can I hold cash in my flexible stocks & shares ISA?
Yes, you can hold GBP cash in your flexible stocks & shares ISA and earn interest on it while you decide where to invest it.
What happens if CMC Invest changes the interest rate?
If CMC Invest changes our interest rate offering, then notice of this will be published on our website and the wallet screen in the app.
Can I access my earned interest at any time?
Once the earned interest is deposited into your account, you have the flexibility to decide how you want to use it. There are no fixed terms. You can withdraw it (GIA & ISA only), invest it or leave it as cash to benefit from compounding.
