Build a grant budget and budget justification

Help me build a budget and budget justification for a grant application. Funder type: [federal / state / private foundation / corporate] Funder's budget rules: [PASTE guidelines: allowable costs, indirect cap, match requirement, budget categories] Project and period: [DESCRIPTION, start and end dates] Staff on the project: [roles, salaries, % effort, fringe rate] Other costs: [supplies, travel, contracts, equipment, participant support, evaluation] Our indirect cost rate: [negotiated rate, de minimis rate, or funder cap] Match or cost share: [cash or in-kind, source] Steps: 1. Build a line-item budget by year, in the funder's categories, showing request, match, and total. 2. Calculate personnel as salary x % effort, plus fringe, with any cost-of-living increase stated. 3. Apply indirect costs to the correct base. For US federal awards, note whether we use a negotiated rate or the de minimis rate on modified total direct costs, and which costs are excluded from that base. [CONFIRM the current rate and rules in the award's terms.] 4. Flag costs that are commonly unallowable (e.g. entertainment, alcohol, lobbying, fundraising costs) or that need prior approval. 5. Write a justification for each line: what it is, how it was calculated, and why the project needs it. 6. Check that the budget matches the narrative: every activity has a cost and every cost has an activity. Return: the budget table, the justification, a list of assumptions, and the questions to ask our finance lead. This is general guidance; verify against the funder's rules and our auditor's advice.
