from this Advice Corner on modular budgeting:

As you design your research proposal, tabulate a rough cost estimate. If you are above but near the $250,000 annual direct cost threshold, consider ways to lessen your expenses. Maybe you have a low-priority Specific Aim that can be dropped or a piece of equipment you could rent rather than buy new.
