Which of these 2 fixed deposit methods will give me more cash after 1 year?

Consider the following two scenarios:

​

Method 1: I have 3 separate sums of money, each one at $30,000. So they add up to $90,000. Now, I place each of these sums in 3 different banks for 3 months (fixed deposit promos).

Assume each bank is offering 3% interest. Every 3 months, I would then take out these 3 sums and put them back again (either in same banks or different banks) for another 3% interest, and repeat this until 1 year is up.

​

Method 2: I have 1 lump sum of money at $90,000. I place them all in one bank for 1 year straight and the interest rate is also 3%.

​

After 1 year, which of the two scenarios will yield better returns in terms of interest rate?

​

I asked ChatGPT about this and it says Method 1 will yield far higher rates after a 1 year period (Method 1 will give about $10k in returns while Method 2 will give $2k+). Is this correct? Sorry, my math is very poor and need people who are good at maths to gauge this for me. 🀣🀣🀣

​

Thank you!

?? I don't get it. why not just put the lump sum in the bank with highest interest instead of split into 3 and desposit seperately.

Good question. I use those daily interest credited

Generally, ChatGPT is not wrong in claiming Method 1 returns a higher yield. However, its higher returns are based on the following assumptions:

  1. Interests earned are re-invested with the principal every time the 3-month FDs matured (compounding effect).
  2. No time gap between maturity and the new 3-month FD term (no time loss like the single 12-month FD).
  3. The 3-month FDs' interest rate of 3% pa is maintained throughout the 12-month period.

Method 2, unless you ald have existing cash account with 3 banks. Otherwise, there'll be T&Cs and yo...
