Answer
For two adults who mostly cook at home, a typical grocery budget in Uruguay is about $700 a month. A similar figure is also cited for Montevideo when it refers specifically to groceries rather than restaurants and cafés.
The final amount depends on what is in the basket. Local seasonal produce, markets, and more basic cuts of meat help keep costs down, while imported products, fish, delicacies, and particular brands of coffee or cheese quickly raise the bill.
To get an accurate estimate, it is better to calculate your actual shopping list rather than rely on an abstract average basket. Compare prices per kilogram or liter, factor in special offers, and do not combine groceries with the separate category of eating out.
