How does DCA monthly and quarterly differ? Why do some prefer one over the other?

In essence, performing dollar cost averaging on a monthly basis will mean more entry points as compared to doing it on a quarterly basis. As a result, there will be more points to average out, thereby possibly reducing the price and volatility of the portfolio.

I have explained further about dollar cost averaging here: Lump Sum vs Dollar Cost Averaging

That being said, you may also wish to take note of the potential transaction fee as you may incur more fees when you perform dollar cost average every month. Hence, this is a point to note as well.

I share quality content on estate planning and financial planning here.

Hi, there is actually no difference other than the amount of times you buy and the total units you buy per purchase. That being said different platforms might have minimum sum when it comes to DCA monthly and quarterly.

For example, FSMone ETF DCA starts from $50 a month (depends of the exchange your dealing with eg HKEX HKD, SGX SGD) while their unit trusts are $100 a month for most of them. Both do not offer a quarterly subscription plan

However for POEMs, you can opt for month or quarterly for their unit trust starting from $100 for monthly and $250 for quarterly minimum. Not too sure about their Shares Builder Plan sorry.

But at the end of the day, investing should be a comfortable process so choose an amount that will let you sleep easy at night be it for monthly or quarterly DCAs.

All the best for your investments!
