If all your revenue or income was to dry up, for how many months or weeks could your business survive based upon the cash that you have in the bank?
You’re not going to know that unless you work out your core monthly overheads – staff costs, premises costs, office costs, and any professional services you’re using. Work out that number, then take the amount of money that you have in your business bank account and divide it by that number – that’s your monthly run rate. That’s how long you can stay afloat for.
If you’re worried that costs are getting high, see where you can cut back, not permanently, but just during this period that we’re in.
You can save money by not using particular services, by downgrading to a free tier on certain services, or even by bringing things in-house just during this period.
