I put in money from 2021 feb until 2022 march. DCA basically over one year. I am at SRI 30%.

My return is around +3.2% p.a. based on excel. The MWR is around +9% to +10%. I dunno how they calculate but i never bothered about their calculation. I never doubted my calculation because pretty darn sure the +9% to +10% does not make sense. Because if i take my current value divide by total investment value, it is a mere 8%+ return. Over 3 years.

I can only confirm that the SA calculation of MWR does not tally with excel XIRR formula. It's not difficult to estimate SA is not per annum return for their MWR. Because it's 20% for your case. If you were making IRR of 20% per year... even with DCA, your investment would be ball park at least 50% more than it was when you started...

You should send an email and get SA to explain the maths behind to you if you so desire. You deserve it.

My suspicion is they probably didnt factor in the 0 8% that they charge us. And they didnt annualise it. Pure suspicion.

According to google yes. MWR and IRR is equivalent but SA MWR macam binatang yang lain.

I digress since you didnt ask but yes i withdrawn from SA 2 days ago. Finally. I acknowledged i invested at a bad time, KWEB was all high when i joined in. I know it is long term but i know what my right investment strategy is now. For MYR holdings, mainly EPF. For overseas, VWRA. No more roboadvisor... after much stumbling in my financial journey, i arrived at ETF and the existence of r/bogleheads.
Even if you can, should you? Would there be other avenues that you can buy VOO or VWRA at a lower cost? Also as non american, remember to look up irish domicile version of VOO.
