Estimated gross monthly cash burn based on the recurring cash outflows entered, before any revenue offset.

Gross monthly cash burn$200,000

Operating outflows used$185,000

Other outflows used$15,000

Annualized burn$2,400,000

$185,000 of operating cash outflows plus $15,000 of other monthly cash outflows gives a gross burn near $200,000 per month.
At the same pace, that is about $600,000 over a quarter and $2,400,000 over a year.
Use the output as a snapshot for planning conversations, then update it when hiring, revenue timing, or major cash expenses change.

This is a planning estimate only. Timing, seasonality, one-time charges, and noncash items can all change how representative the monthly burn figure really is.

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Summarize recurring cash outflows

A single gross-burn number can make budgeting and cash-planning discussions easier than working from several monthly cash categories separately.

Pair burn with runway estimates

Gross burn often works best alongside a runway calculation when you also want to compare cash balance and burn pace.

Review changes after hiring or spending shifts

Updating monthly outflows after staffing, rent, or vendor changes can show how quickly the burn picture has changed.
