# Calculations for my Portfolio

First excuse my maths and limited finance knowledge.

I am testing investing in crypto and trying to calculate my ROIs, Profit/Loss etc and getting stuck a bit and was wondering if anyone can help!

First example Lets say i buy

10 BTC for 100 USD/ coin on 1st of January making the total investment of 1000 USD

i know we all wish

Lets say the `Current Value for BTC is 300 USD/coin`

My `Profit/Loss will be 2000USD` which is `3000 (current value) - 1000 (initial investment)`

My `ROI is 2000/1000` which is `2%`

I think so far i am on the right track!

Now my first question is Lets say i buy

``````10 BTC for 250 USD / coin on 5th of Jan
``````

How do i factor in

1. My Profit Loss
2. My ROI

My Second question is Lets say i SELL

``````5 BTC for 150 USD / coin on 10th of Jan
``````

Again how do i factor in my

1. My Profit Loss
2. My ROI

I think what i am missing is how i calculate my Total Invested amount.

And my third question is how do i calculate my `Daily ROI` after buying and selling coins over time?

I appreciate that this is way too much to ask, so perhaps google terms to search for will suffice. As i think i am missed the correct terms to use in my searches.

Thanks

• 2000/1000 is 200% not 2% Jul 4 at 11:28
• @BobBaerker isn't it 100% gain because it doubled? Jul 4 at 15:05
• If \$1,000 doubled, it would be worth \$2,000. Started with \$1,000 and it rose to \$3,000. Gain is \$2,000. That's 200%. Jul 4 at 15:23
• Do you really think you should be "investing in crypto"? Jul 4 at 19:52
• Two percent is .02 so multiply that by 1000 and get back to me :->) Jul 4 at 23:20
