The budget describes the costs to be incurred by the program and explains why each is needed. Reviewers use the budget as a mutually reinforcing summary of the entire proposal, so considerable thought should go into its preparation.
Budget requirements may vary widely by type of award, cost reimbursement or fixed price, or by sponsor, federal or private. Most sponsors provide detailed instructions and printed forms for budget preparation. RSCs have expertise in the development of budgets and stand ready to assist in their preparation. RSCs can also supply budget templates to assist those Principal Investigators who prefer to prepare their own budgets before conferring further with their RSC.
