If loans, or loan modeling, are allowed in your plan, you will have access to this screen.  Your Summary Plan Description will indicate whether loans are permitted under the plan.  If you want to "model" a loan, or find our how much a payment would be based on data you enter, complete the Loan Calculator accessible under Loan Modeling.  A payment amount will show in the Calculator box.  If you do not currently have a plan loan, this screen will not be available to you.
