Budget Tab

Click the Edit/Modify button to add a detailed, three-year budget in USD and corresponding justification. Please refer to the RFA for funding levels and allowable expenses.

  1. Please enter the applicant PI and every Additional PI in the Personnel Costs section even if not requesting salary in order to reflect each PI’s percent effort.
  2. For PIs requesting summer salary, please only select Academic (referring to 9 or 10 months) for the Appt Type (which refers to the individual’s institutional appointment) and input the base salary corresponding to this appointment type.
  3. For PIs requesting summer salary at non-US institutions and/or those receiving 12 months of salary, the program allows them to request an additional 1 month of summer salary for their research effort on the project, provided that the summer salary request is not in violation of their institution’s policies of more than 100 percent effort per year. Please only select Annual for the Appt Type (which refers to the individual’s institutional appointment) and input the base salary corresponding to this appointment type.

You will need to close and reopen the budget for the changes to populate.
  5. Do not select TBD in the Personnel drop-down list if the personnel are known. They must be first entered in the Project Personnel section as outlined above.

Please note that the budget justification should be detailed and appropriate for the funds being requested. An insufficient budget justification will result in the proposal not being considered further.

  9. Within each budget period, you have the ability to copy the budget and justification from the previous period and then make edits as needed. Important note: If content has already been entered in year 2 or 3, for example, copying from the previous year will not replace the content – it will only add the previous year’s content, potentially duplicating the budget the next year. Duplicated entries can only be deleted individually by line item.

Click the Assign Other Support for This Proposal button to add other support to this application. This will display all other support related to the applicant that was previously added to their SAM profile. Reporting overlap is required to submit an application.
