I have updated my Mafia Wars Calculator (Thanks to Frederik) to include 5-Star hotel and Mega Casino. Everything else remain the same, all you need is to enter your current quantity and buy the property that gives you the lowest ROI. Read more from my Mafia Wars Cheats for my first guide on this cool facebook game.

I did not have much time playing cause of heavy workload. But a tips to remember is to make sure you select the correct tab when you are doing your job. I did not know until I had Soldier level

Have fun playing Mafia Wars at Facebook. I saw that there is Mafia Wars too in MySpace, not sure if they are the same.

Thanks for the nice spreadsheet; however, the worksheet is password-protected, and I need to unprotect it to update the price of the Apartment Complex. The spreadsheet shows $200,000, but my Mafia Wars page says $300,000 (perhaps because I already own 5 of them?)
Thanks in advance for the help!

NEVER MIND! Please disregard my recent request — I entered the quantity “5″ in the wrong row. It updates correctly. Thanks again!

This is nice, thanks!
I’d like to suggest a change. In the ROI column, make the numbers all have just one or two decimal places. that way it’s easier to see which one has the best ROI.
Even better would be to use conditional formatting to highlight the cell with the best ROI.
haha! i thought i was the only, um, nerd that did this..! But shouldn’t you include the cost of the lot in the ROI for a property? But really, clearly the best investment is Mike’s even as the price continues to rise. Probably not until you purchase 40 or more does it (i only have 20 now) bottom out..

Hey well, idk if the formula is 100% spot on because my numbers are off but it may be because I have hundreds of each property mostly mega casinos and 5 stars. FYI.
this is hard.. because i already own 17 MC then the cost of 1 MC is 98,000,000 already so how would i know if its better to get another MC rather than a cheaper 5 star hotel? MC – Mega Casino
I used his calculator for inspiration and developed my own. It’s completely unlocked so you can further customize it if desired.
use the greasemonkey script for this with firefox, no need to cut/paste/etc and is always current with whatever discount / benefits / etc since it reads from your actual page. This only seems to work with facebook.
Users,
There is an astronomical error in the spreadsheet.
The return on investment should be the profit divided by the cost of investment. The opposite is made in the spreadsheet.
This will badly influence your decisions on investments.

Charly,
I could be wrong, but I believe you are mistaken. Dividing Cost by profit and taking the lowest number (as is advised in he spreadsheet) does give the wisest buy. It’s the same as dividing profit by investment, and taking the highest number. Perhaps the ROI is a misnomer, but there is no fault with the logic as far as I can see.
yup you guys are right. I have changed the ROI to Return in Days because my intention is to indicate how many days you will get ROI (not directly ROI).
My new calculator that includes new enhance feature to tell you the best 3 buys
