Calculator questions
How does the My Giant Sandwich calculator work?
Enter the upgrade cost and the income rates visible in your own game. The calculator compares the change and estimates time to buy and payback.
Does the calculator use official hidden values?
No. It uses only the values you enter and does not assume prices, recipes, offline multipliers, or caps.
What should I enter for away earning rate?
Use the percentage or effective rate that you can observe in your own game. If you cannot verify it, leave the rate at the neutral value you want to test and treat the result as a scenario.
