How to Calculate Cash Burn Rate
There are two main types of cash burn rate:
1. Gross Burn Rate
This is the total amount of cash a startup spends in a month.
Formula:
“`
Gross Burn Rate = Total Operating Expenses per Month
“`
These expenses include salaries, rent, utilities, marketing, product development, etc.
2. Net Burn Rate
This subtracts cash inflows (like revenue) from your expenses.
Formula:
“`
Net Burn Rate = Cash Outflows – Cash Inflows (per month)
“`
Net burn rate shows how much cash you are actually losing each month.
