Pros and cons
Betterment
Pros
- No monthly fee on the Cash Reserve account, at $0 a month
- Headline rate of 3.5%, variable, above the cash-management median of 3.41%
- Only $10 to open, with unlimited withdrawals
Cons
- The rate is variable, so the 3.5% headline can move with the policy rate
- A minimum of $10 is still needed before the sweep starts earning

KDI Save
Pros
- No lock-in, so you can withdraw at any time without charges, with returns credited daily
- A MYR 100 minimum deposit keeps the entry point modest

Cons
- The MYR 100 opening deposit sits well above the €0.17 minimum across savings accounts

Questions about each
Betterment
What rate does the Betterment Cash Reserve pay?+
The Cash Reserve pays a headline rate of 3.5%, and the rate type is variable. Because it is variable, the figure can rise or fall with policy rates rather than being fixed for a set term. Treat the headline as a starting point rather than a promise.
Is there a monthly fee on the account?+
There is no monthly fee. The monthly fee is $0, and the pricing model is a no-monthly-fee one, which is the most common model in this ranking. You keep the full amount you deposit earning interest.
KDI Save
Does KDI Save charge a monthly fee?+
The monthly fee is MYR 0, and the account is sold on a no monthly fee model, so there is nothing to pay each month for keeping the balance open. Nothing in the access terms adds a charge for taking the money out either.
Who regulates KDI Save?+
The account is licensed by the Securities Commission of Malaysia under eCMSL/A0008/2007, and it is operated by Kenanga Investment Bank Berhad, a Malaysian bank. Keep the licence reference handy for your own records when you open the account.
