This calculator is available on the internet at absolutely no cost. So, to start using this calculator, you will need to enter in your RuneScape username. Then, set a goal level or experience point and find the best option for you. 

You can begin by entering your RuneScape username and hitting the ‘Calculate’ button. This will automatically load your current user experience and set a goal appropriate to your level.

If you’re a non-member of RuneScape, or do not wish to enter your username, then you can manually fill in your level or experience in the current and goal fields. Using the dropdown to the right of the username field, you may select a different skill to calculate. 

Once the above required data fields are entered, the calculator will calculate the approximate number of actions that have to be completed. To help narrow down your selection of items, you may choose a main category and then further select sub categories (when available).

If you want some more information on a specific action, then there is a ‘+’ button provided to you. This will open a popup including some of the more detailed information about the item. It includes a breakdown of the materials required and how much they cost to purchase from the Grand Exchange.
