26 y/o female here with 40k savings. Savings rate is 30-40%. Aiming to reach 100k by 30. What should I do?

Start investing , from 40k easily reach 100k by a year which is highly doable. compounding interest is a very big thing .​​​

About there. On track. Got at least $60k salaries a year?
$60000 x 80% = $48000 (after CPF)

$100000 - $40000= $60000
$60000/4 = $15000 (saving per year)
15000/12 =$1250 (saving per month)

If you have to save at least $1300 per month should be no problem to hit $100k without doing any investment.

You probably can hit $200k at mid 30s without doing any fancy thingy.
