If you put money into a Monzo investment stocks and shares pot it shows you how it’s doing as a percentage. If you keep irregularly adding more to that pot, how does it work out the percentage?
Eg if that pot says it is up 5% after ten different top-ups, then how is that 5% calculated?
That’s the return on investment, the amount of money in the pot doesn’t affect what the rate of return is. So adding money won’t change that percentage.
Okay, in this case I’m either making more or less than I thought and I’m too tired to work out which. I’ll check that out tomorrow, thanks for the correction!
I have a Hargreaves Lansdown SIPP and S&S ISA, along with a work pension elsewhere, and they also don’t calculate time-weighted return.
It’s a big frustration of mine and I’m intrigued which platforms do actually calculate this for you.
I sat down last weekend and went back years trying to work out all my historical contributions versus current value.
In addition, I find with HL that if you sell some holdings and reinvest, the gain/loss is calculated against your ‘cost’ rather than contributions, so you can quite easily wipe out your gain/loss just by shuffling things around - not in the slightest bit helpful.
I think someone produced an automated way of doing TWRR on T212, which I keep meaning to look into but keep putting it off as I hope T212 will do It eventually.
If you put the £100 in 12 months ago in one lump sum and it’s up 5% then your return is indeed 5%. However, if you put it in monthly over the 12 months then your return is more like 10%.
I would also be more happy with a simple “how much did this fund change this month”, which is independent of how much you have invested. You can look up the fund performance on other websites to see this, but it isn’t easy.
