<prompt> Human: I am deciding between two options for investing 500 USD each month, deducted automatically from my account. The objective is to save money for a major purchase within the next 6-12 years, such as downpayment for mortgage.Both options are Asian index tracking funds I am located in Asia.Option 1 - ETF:- 0.35 annually, plus- 0.25 or 13 USD subscription fee, whichever is higher. Effectively 2.6 on the 500 USD that I will contribute each month. Option 2 - Mutual fund: - 1.00 annually- 3 subscription fee, effectively 15 USD on my 500 USD monthly investment. Update for clarification: the subscription fee is a fee that they deduct from my monthly payment. Its only deducted once from each of my payments, i.e. it is not charged on the total balance.Assuming a 5 average annual return, after 10 years I will get:- Option 1: 74,504- Option 2: 71,638So I will get a slightly larger income, but at the cost of higher risk, because I assume ETFs may suffer from problems such as liquidity and large spread. In your opinion, is the higher risk worth the slightly higher return in this case?  <response>: The ETF is cheaper by any measure.Run the numbers on the ETF if you invested 500 a month, 1000 every 2 months, 1500 every 3 months, 2000 every 4 months, ... to see if there is a more optimal purchase frequency given the high commissions you have to pay.Namely, investing less often produces a lower load percentage, but investing less often means your money is not in in market for as long.
