Days of Oxygen – This Month

DOO – Days of Oxygen – is a measure of how much breathing space you have if revenue drops or ceases.
For start-ups and early-stage companies DOO is your “Runway”, a value that investors want you to always be mindful of.

This is the amount of cash you have available for use (where you don’t need to repay anything such as a credit card or term depository)
All your open invoices (i.e. sales revenue that does not include interest, grants, saleable assets, etc.)
Work that you will realistically expect to invoice in the next 30 days
Costs that you will need to pay in next 30 days (for goods/services you are selling/rendering)
Any other outstandings, etc.
Fixed costs: Your estimated one month’s (30 days) operating expenses (e.g. rent, internet charges, etc.)
Cash available: your “buffer”
Your breathing space or runway

“Best practice” = 120 days DOO
* For added “insurance”, omit or discount, WIP

Forecast – Next month

Do this as a rolling forecast


** A realistic safety margin should be at least one month’s OpEx
