Understanding the Inputs
Key components required for runway calculation with revenue growth
Current Cash Balance
Total cash and cash equivalents available to the company right now.
Bank account balances
Short-term investments
Available credit lines
Monthly Burn Rate
Total monthly operating expenses including salaries, rent, and other costs.
Salaries and benefits
Office rent and utilities
Marketing and software costs
Monthly Revenue
Current monthly recurring revenue or total monthly revenue.
MRR for SaaS companies
Total monthly sales
Subscription revenue
Monthly Revenue Growth Rate
Expected monthly percentage increase in revenue (e.g., 10% = 10).
Based on historical trends
Projected growth rate
Conservative estimate recommended
Formula Used
Runway = Cash Balance / Net Monthly Burn
Net Monthly Burn = Monthly Burn Rate - Monthly Revenue
Revenue(t+1) = Revenue(t) × (1 + Growth Rate)
The calculator projects monthly cash flow by accounting for growing revenue, which extends runway as revenue increases over time. When revenue exceeds burn rate, the company reaches profitability.

The **Startup Runway** is the number of months a company can continue operating before running out of cash, assuming current burn rate and revenue trends. When accounting for revenue growth, runway extends as revenue increases, potentially reaching profitability before cash runs out.
A Measure of Financial Sustainability
Runway provides a crucial timeline for strategic decisions, including when to start fundraising, when to optimize costs, and when revenue growth will lead to profitability. It's a vital metric for founders, investors, and board members.
Runway Calculation with Revenue Growth
Traditional runway calculation divides cash balance by monthly burn rate. However, accounting for revenue growth provides a more accurate projection by reducing net burn over time.
The Calculation Process
The formula accounts for growing revenue:
Net Monthly Burn = Monthly Burn Rate - Monthly Revenue
Most investors recommend maintaining at least **12 months of runway** at all times. This provides sufficient time to execute fundraising (typically 3-6 months) while maintaining operational flexibility.
Impact of Revenue Growth on Runway
Revenue growth significantly extends runway by reducing net burn over time. As revenue approaches and exceeds burn rate, the company moves toward profitability.
Path to Profitability
When monthly revenue growth is strong, net burn decreases each month. Eventually, revenue may exceed burn rate, creating positive cash flow and effectively infinite runway (assuming sustainable operations).
Growth Rate Considerations
Conservative growth rate estimates are recommended. Overestimating growth can lead to dangerous runway miscalculations. Consider:
Historical growth trends
Market conditions and competition
Sales cycle length
Customer acquisition costs
Strategic Planning and Fundraising
Runway calculation with revenue growth enables strategic decision-making for fundraising, cost optimization, and growth planning.
Fundraising Timeline
Start fundraising when runway reaches 12-18 months. This provides adequate time to complete the fundraising process (typically 3-6 months) while maintaining operational buffer.
Cost Optimization
If runway is below 12 months, prioritize cost reduction and revenue acceleration. Focus on high-impact initiatives that extend runway quickly.
Conclusion
Startup runway with revenue growth provides a dynamic view of financial sustainability, accounting for the positive impact of growing revenue on cash flow. It enables strategic planning for fundraising, cost management, and path to profitability.
Maintain at least **12 months of runway** at all times, start fundraising early, and use conservative revenue growth estimates to ensure accurate projections.
Frequently Asked Questions
Common questions about Startup Runway with Revenue Growth
What is startup runway?
Startup runway is the number of months a company can operate before running out of cash, based on current burn rate and revenue. When accounting for revenue growth, runway extends as revenue increases over time.
How does revenue growth affect runway?
Revenue growth reduces net burn over time (burn rate minus revenue). As revenue increases, net burn decreases, extending runway. If revenue exceeds burn rate, the company reaches profitability with effectively infinite runway.
What is a good runway for a startup?
Most investors recommend maintaining at least 12 months of runway. This provides sufficient time for fundraising (typically 3-6 months) while maintaining operational flexibility. Early-stage startups may operate with 6-12 months, but should start fundraising when runway reaches 12 months.
When should I start fundraising?
Start fundraising when runway reaches 12-18 months. Fundraising typically takes 3-6 months, so starting early ensures you have adequate cash throughout the process. Don't wait until runway is critical.
How accurate are revenue growth projections?
Revenue growth projections are estimates based on historical trends and market conditions. Use conservative estimates to avoid dangerous runway miscalculations. Actual growth may vary due to market conditions, competition, and execution challenges.
What if my burn rate increases?
Burn rate can increase with scaling, hiring, and expansion. Regularly update runway calculations to account for changing expenses. If burn rate increases faster than revenue growth, runway will decrease.
Can runway be extended without fundraising?
Yes, runway can be extended by reducing burn rate (cost optimization), increasing revenue growth, or both. However, aggressive cost cutting may impact growth, so balance is important. Revenue growth is the most sustainable way to extend runway.
What happens when revenue exceeds burn rate?
When monthly revenue exceeds monthly burn rate, the company generates positive cash flow and reaches profitability. Runway becomes effectively infinite (assuming sustainable operations), though maintaining cash reserves is still important for growth investments.
How do I calculate net burn rate?
Net burn rate = Monthly Burn Rate - Monthly Revenue. This represents the actual cash consumption each month after accounting for revenue. As revenue grows, net burn decreases, extending runway.
Should I use MRR or total revenue?
For SaaS companies, Monthly Recurring Revenue (MRR) is most appropriate as it represents predictable, recurring revenue. For other business models, use total monthly revenue. The key is consistency in how you measure revenue over time.

Who Should Use This Calculator?
Startup FoundersTo plan fundraising timelines and understand when revenue growth will lead to profitability.
CFOs & Finance TeamsTo provide accurate cash flow projections and strategic financial planning.
InvestorsTo assess portfolio company financial health and fundraising needs.
Board MembersTo monitor financial sustainability and make informed strategic decisions.
Limitations & Accuracy Considerations
Revenue Growth Assumptions: Projections are estimates and actual growth may vary significantly due to market conditions, competition, and execution challenges.
Burn Rate Variability: Expenses can increase with scaling, hiring, and expansion. Regularly update calculations to reflect changing costs.
Seasonal Variations: Revenue and expenses may fluctuate seasonally. Use average or conservative estimates for more accurate projections.
Real-World Examples
Case A: High-Growth SaaS Startup
A SaaS company with $500K cash, $50K monthly burn, $20K MRR, and 15% monthly growth. Revenue growth extends runway from 10 months (without growth) to 18+ months as revenue approaches burn rate, creating path to profitability.
Case B: Pre-Revenue Startup
A pre-revenue startup with $300K cash and $40K monthly burn has 7.5 months runway. Without revenue, runway is fixed. Once revenue starts, even modest growth (5-10% monthly) can significantly extend runway.
