Need a little help: Measuring/Viewing my ROI

Hey guys,

Im trying to figure out my ROI and cant seem to get a clear grasp on it, would be great to get some help and maybe a formula to figure it out.

Scenario:
Deposited 10,000 USDC to curve.fi/y
Deposited LP Tokens to curve.fi/y LP Vault (91% ROI)

Screen Shows:
8,863.53 yUSD
(9,529.42 yCRV)

How do I figure out my CURRENT USDC value?
How do I see my ROI and profit since the first deposit?

Really appreciate the help so thank you in advance

Try looking at https://yieldfarming.info/yearn/yvault/

Legend thanks man, that was helpful.

Looking forward to interfaces that make it a little easier to follow.

Looking at the historical returns would I be correct in assuming that the more that is in the vault the lower the ROI becomes?
