Budget and Cost Justification Guide

Last reviewed: April 2026

A persuasive budget is explainable. Reviewers need to see what each cost does, why it is necessary, and whether the amount is proportionate.

What good cost rationale looks like

A strong rationale answers:

  • what is being purchased
  • why it is necessary
  • what deliverable it supports
  • why the amount is reasonable

Notes by funding type

  • For grants: map each line to eligible scope and expected claim evidence.
  • For accelerators: focus on resource allocation and execution feasibility.
  • For pilot funding: tie cost to deployment milestones and measurable outcomes.
  • For debt financing: show repayment realism and downside planning.
