Use Cases
Assess financial health for fundraising
Determine how many months of runway you have to show investors, helping you plan your next funding round.
Example: With $300k cash, $10k revenue, and $40k expenses, your runway is 10 months.
Plan cost-cutting measures
See how reducing expenses or increasing revenue extends your runway, guiding budget decisions.
Example: Cutting expenses by $5k/month adds 2 months to your runway.
Frequently Asked Questions
- How is the monthly burn rate calculated?
- The monthly burn rate is calculated as expenses minus revenue. If your expenses are $50,000 and revenue is $20,000, your burn rate is $30,000 per month.
- What does the runway represent?
- Runway is the number of months your startup can operate before running out of cash, assuming no changes in revenue or expenses. It's calculated by dividing your current cash by the monthly burn rate.
- Can I use this calculator if my revenue exceeds expenses?
- Yes. If revenue is greater than expenses, your burn rate is negative, meaning you are cash-flow positive. In that case, the runway is not applicable, but the calculator will indicate that you are not burning cash.
Tips & Common Mistakes
Tips
- Use conservative estimates for revenue and expenses to avoid overestimating your runway.
- Re-calculate your runway monthly as your financials change.
- Include all recurring expenses, not just salaries, to get an accurate burn rate.
- Consider having at least 6 months of runway to give your startup time to grow.
Common Mistakes to Avoid
- Forgetting to subtract revenue from expenses, leading to an overestimated burn rate.
- Using one-time expenses or revenue in the calculation, which distorts the monthly average.
- Ignoring that runway is a static estimate; it doesn't account for future changes in revenue or expenses.
