- FD interest calculation : $10,000 x 3.5% = $350 x 1 day / 365 days = $0.9589 interest daily
- KDI Save's returns : $10,000*(1+3.5%)^(1/365)-1 = $0.9425 interest daily
- KDI Save's returns after 1 year for $10,000 in 3.5% = $10,350 interest yearly
1. I thought compound interest is superior to regular FD but in a real world, both FD and KDI Save rate "compounding the interest and principal over time" after a year results 10,350 same as FD.
2. If a bank's promo FD is more than 3.5% would yield higher returns than KDI Save
3. KDI Save's depositors can withdraw 9 days with interest but banks penalize early FD withdrawal.
4. KDI's day 1 interest 0.9425 is lesser than bank's 0.9589.
I had wanted to raise queries, but I came to these conclusions, am I wrong?
Your thoughts are welcome.
