Fixed, rolling, annual: reading a grant deadline

Every grant on this site is tagged with a deadline type. Here's what each one means for your timeline.

Fixed

One date. Miss it and you wait for the next cycle — which may be a year away. Start the application at least three weeks early; you'll need documents from third parties.

Rolling

Applications are accepted continuously and reviewed in batches. There's still an internal cadence — often monthly — so applying earlier in a batch usually means a faster decision.

Annual

A single call each year, usually the same quarter. Put a reminder in your calendar for one month before the typical opening date.

Recurring

Multiple calls per year on a published schedule (e.g. BIRAC BIG runs twice a year). Pick the call that lines up with your prototype timeline.

When a grant says rolling, we don't show a fake deadline — we show "Rolling applications" and, where the provider publishes one, the review cadence.
