50% rule / Quick Analysis calculator for rental property

6 Replies

Does anyone have a spreadsheet calculator for a quick analysis on rental & small multi-unit property? It seems like the easiest and fastest way to evaluate an investment property is by the 50% rule. I am still primarily a wholesaler so I am looking for a tool to help me evaluate rental property quickly. Does anyone have a 50% rule calculator that they would not mind sharing? It would be GREATLY appreciate it. Thanks guys!

Hey Eric,

Thanks for your reply but I had already looked into that source. I just wanted a simple excel spreadsheet calculator to evaluate rental property quickly around the 50% rule. I was able to create one myself and if anyone else is look for something like this, I am willing to share. Thanks.

Here's a quick 50% rule, %-of-rent, cash flow, and cap rate calculator anyone can use on Google sheets: 


I didn't lock it; anyone can edit it. Please don't change the formulas or it won't work for the next person; download it and use it offline if you want to change/add to it.

If your looking to go based on the 50% rule you can quickly do it without any tools.

Monthly rent x6 = Your 50% rule NOI

NOI divided by aquisition cost = cap rate.

James your 50% includes capex so you would not have even a guesstimated NOI.
