Having trouble with ROI

[Robin Brown]

Hey all. I am still very new and have not made any purchases yet but our state Gov. has opened up a new grant for first home buyers. This looks to make things possible to get a small 2bed apartment to start the portfolio. (must live in it first and hope to only live for a year before moving to a home for my partner and myself)

Anyway I am trying to sort out an excel spreadsheet that has 
- a list of properties
- what they are listed for
- what I would like to get them for
- rent
- rate costs and extra expenses
- loan repayments
- monthly and yearly income
- and ROI

I am just having a bit of trouble understanding how I work ROI out.

My first example is 50k of my own money with a yearly return of $1872

Do I do 1872/50000?
