The annual Monopoly at McDonald’s game is officially underway, with a chance — albeit small and extremely caloric — of winning cash and prizes. McDonald’s claims ‘the odds are better than ever’, but does not address the actual investment needed to win the most coveted items.

Now, with Eat With a Spork’s handy calculator, you can find out how many Big Macs it would take to give you the best chance of winning. It also calculates the financial and nutritional investment required. The results are unsurprisingly horrifying.

Based on the 1 in 301,245,250 odds of winning the 2011 Shelby GT 500, you can expect an investment of the following:

• $37,300,000.00
• 5,400,000,000 calories
• 290,000,000 grams of fat
• 10,400,000,000 milligrams of sodium
• 450,000,000 grams of carbohydrates
