Burn rate: Burn rate is the rate at which a company is losing money.  It is typically expressed in monthly terms.  E.g., "the company's burn rate is currently $65,000 per month."

If the shareholder capital is exhausted, the company will either have to start making a profit, find additional funding, or close down.
