I see why your calculations are so out of whack.

You’re dividing the cost by the income and calling it a return in days. This is not correct.

Income is returned hourly, not daily. So if you divide the cost by the income you get the number of hours it’ll take to return your investment — not the number of days.

Rename the column “Return in Hours” and it’ll be fine.

If you really want the number of days, replace the formula with:

(COST/INCOME)/24

Better still, use INCOME/COST and format the result as a percentage. This is the return on investment (ROI). The higher the percentage the better the return.

1) After completing Enforcer you earn a money plate which gives you a 5% reduction on property costs. This will affect the return on investment. Your calculator doesn’t take this into account.

2) Return in days is pretty meaningless. Are you seriously suggesting it’ll take me 1,486.67 days to return my investment of 101 Mega Casinos? That’s 4 years!! I’ve returned my investment several times over, and I’ve only been playing a few months!

3) No account is taken for protection and damage to property. When property is damaged, the income drops. When fully damaged, income is only 30%. The cost of repair needs to be figured into the calculations, along with the 5% reduction offered by the State Senator bonus (Capo level) and the cost of protecting all your property.

Note that when protecting property for the first time, it’s best to buy 1 of each protected property first, then protect them all in one go. Thereafter, buy properties in 10s. They’re automatically protected at no further cost (until they’re damaged, at least).

Return On Investment (ROI) is also a far more meaningful figure — where the higher the percentage the better. ROI is INCOME / COST, formatted either as a percentage or a ratio.

For example, if you buy your first Mafia Mike for $8,000, your income will be $12,000 every hour. That’s an ROI of 150% every hour (12,000 / 8,000).

If you have the 5% reduction, that’s $7,600 for the first Mafia Mike (an ROI of nearly 158%).

With each purchase, the cost will increase by 10%. I currently have 362, so the 363rd will cost me $282,720. But that’s still an ROI of 4.24%, which’ll return my investment within 24 hours ($12,000 * 24 hours = $288,000).

Note also that you can make huge savings by purchasing properties 10 at a time, and never owning any more than 10 of each land item at any one time. When land is used, it reverts back to its original price.

Mafia Mikes are an exception since you can only buy 1 at a time. If you have 10 abandoned lots, but can only buy 1 Mafia Mike, it makes more sense to place some Rent Houses or Valu-Marts on the abandoned lots before buying one abandoned lot for your Mafia Mike. Alternatively, wait until you have 20 new mafia so you can buy 10 Mafia Mikes in a row.

Hope that helps.

But I sure wish they weren’t locked. I’d like to get rid of columns A & B so that I can see the game and the calculator, too. And I’d just like to be able to add things. Why is it locked?
