How much interest will I earn on settled cash held in my investment accounts?
You’ll earn 2% gross (2.02% AER or Annual Equivalent Rate) interest on uninvested, settled cash balances held in any investment account on the CMC Invest App.
What is 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 AER reflects the rate of interest earned each year when payments are not withdrawn from accounts.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 is 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Settled cash refers to funds that have been processed, cleared and are available to be withdrawn from your account.
When will I receive my interest payments?
Interest will be paid monthly. You will 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 are credited to your account.
Will I be taxed on my earned interest?
If your interest is earned in an ISA or SIPP, you will not have to pay tax on it. However, tax may be owed on any interest earned within a General Investment Account, if this exceeds your annual interest allowance. 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.
Can my earned interest be accessed 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, invest it (perhaps in our Flexible Stocks & Shares ISA for even more flexibility), or leave it as cash to benefit from compounding.
