Thanks for the important money question! From what I've read, the South African bank with the highest interest rate on savings accounts right now is Investec with 1.8% on balances up to R1 million. Of course, rates can change monthly so it's always wise to shop around and weigh up any fees too. On PriceCheck, we make comparing offers from different providers simple and point you towards their current best deals. Why not search our site another time and allow me to do a full review of your savings options? In the meantime, I hope you're able to find a rate that helps your money grow while serving your needs. Wishing you all the best with your expenditure adventure!
