Burn is a cash-run-rate concept. Use actual or representative cash inflows and cash outflows on the same monthly basis, not accrual accounting revenue and expenses when their timing differs.

Frequently asked questions

What is monthly burn?

Monthly burn = monthly expenses + monthly one-off costs − monthly revenue. The cash the business spends per month when expenses exceed revenue — the headline number for any "can I afford this?" question.

Monthly Burn

What is burn/week vs burn/month?

Burn/month ÷ 4.33 to convert to per-week burn. A weekly read is useful when the cash decision is event-by-event (hiring, big inventory order) rather than month-by-month.

Monthly Burn

What if revenue exceeds expenses?

A negative burn is technically "cashflow-positive on the month"; treat a small negative burn as "no cash drag this period". The runway calc still applies, but the burn figure reads as a surplus rather than a drain.

Monthly Burn

How do one-offs affect burnout?

There is no universal numeric benchmark for this decision. The right comparison depends on the industry, geography, business model, time period and exact metric definition. Use the business’s own history, economics and explicit target unless a verified benchmark matching that scope is available.
