Know exactly when your startup will run out of money and get a strategic plan to extend it

You're scaling fast, but one question keeps you up at night:

"How long until we run out of cash?"

Most founders are flying blind when it comes to runway planning. You know your current burn rate, but what happens when you factor in revenue growth? What if expenses increase? When will you actually reach break-even?

Stop guessing. Start planning.

The Problem Every SaaS Founder Faces

💰 You know your current cash balance — but have no idea how long it will actually last

📈 Your revenue is growing — but so are your expenses, and you can't predict the impact

🤔 You're making critical decisions — like hiring, marketing spend, and fundraising timing — without knowing your true runway

⏰ Investors keep asking about burn multiple and capital efficiency — metrics you're not even tracking

📊 Your simple "cash ÷ burn" calculation — ignores revenue growth and gives you false confidence (or panic)

Introducing: The Runway Calculator Built for A Growing SaaS

This isn't your typical "cash divided by burn" calculator.

Cornell's SaaS Cash Runway Calculator factors in revenue growth, break-even projections, and advanced SaaS metrics that sophisticated founders actually need.

In 60 seconds, you'll know:

✅ Your exact runway — down to the month, factoring in revenue growth

✅ Your break-even date — when you'll stop burning cash (if ever)

✅ Your burn multiple — how efficiently you're acquiring revenue (the metric

VCs care about)

✅ Your capital efficiency — months of runway per $100k raised

✅ Scenario planning — what happens if you grow faster or slower

✅ Strategic recommendations — specific next steps based on your financial

position

Why This Calculator is Different

Most runway calculators assume:

  • Your revenue stays flat (wrong!)
  • Your expenses never change (wrong!)
  • You don't need to understand efficiency metrics (wrong!)

Cornell's calculator factors in:

  • Monthly revenue growth rates
  • Break-even projections with compound growth
  • SaaS-specific metrics (burn multiple, capital efficiency)
  • Strategic recommendations based on your timeline

FAQ

Q: How is this different from other runway calculators? A: Most calculators assume flat revenue and expenses. This factors in growth rates, break-even projections, and SaaS-specific efficiency metrics.

Q: What if I don't know my exact new ARR growth? A: Use your best estimate. The calculator will still give you valuable insights, and you can adjust the numbers to see different scenarios.

Q: Is my data secure? A: Yes. All calculations happen in your browser. Nothing is stored on servers or shared.

Q: What's burn multiple and why does it matter? A: Burn multiple (net burn ÷ new ARR) shows how efficiently you acquire revenue. VCs use this to evaluate your capital efficiency.
