Frequently asked questions

What is burn rate?

Net burn is what you spend each month minus what comes in. Runway is cash on hand divided by net burn.

Why does grant timing matter?

Many grants pay after you spend (reimbursement) or in milestones. If the money arrives after your cash runs out, it does not extend your runway.
