Is there a calculation to work out how long a business can survive without income?

Yes, a business can estimate how long it can survive without income by calculating its cash runway. This involves assessing the total cash reserves and dividing that by the monthly operating expenses. Additionally, businesses should consider fixed and variable costs, as well as any outstanding debts, to get a more accurate picture of how long they can operate without revenue. Regular financial projections can help in planning for potential downturns or income gaps.
