Welcome to the Resource Requirements Calculator. This tool will help you plan your resource requirements for the big building upgrades (or research projects).
You can make several entries in this calculator, one for your main account and one for each farm account. You specify your resource requirements in your main account, and specify your available resources in all your accounts, which will allow you to track in your main account how close you are to your target for all required resources.
Using this tool will help you focus on the right resource, and will give you good insight in when you have enough resources to do your next upgrade or research project, so that you don't start opening your resource items too early.

To use this tool you need to Register, so that you can save your settings.
