Cash Runway Countdown Timer

A runway countdown shows exactly how many months and days remain before your startup runs out of cash, based on your current burn rate and revenue. Unlike a simple division, this tool accounts for revenue growth and lets you model spending changes in real-time. See our runway calculation guide for the full methodology.

Most advisors recommend 18-24 months of runway. Less than 12 months is a yellow flag, and under 6 months is critical. If you are planning to fundraise, start 6-9 months before you run out to avoid desperate negotiations. Use the burn rate calculator to see how burn changes affect your timeline.

There are two levers: reduce spending or increase revenue. This tool shows exactly how much runway each spending cut adds. Common strategies include renegotiating vendor contracts, pausing non-essential marketing spend, and optimizing infrastructure costs. Read our burn rate optimization guide for detailed tactics.

Net burn rate is your total monthly expenses minus your monthly revenue. It represents how much cash you actually consume each month. For example, if you spend $50,000/month and earn $15,000 in revenue, your net burn is $35,000. This is the number that determines your actual runway. Model scenarios with the cash flow forecast calculator for a detailed monthly projection.

Revenue growth reduces your net burn over time, extending your runway non-linearly. A 10% monthly revenue growth rate can nearly double your runway compared to flat revenue. This tool models revenue growth month by month so you can see exactly when growing revenue offsets your burn. Use the runway calculator for advanced growth scenarios.
