About the Cash Runway Scenario Simulator
Enter cash and burn to compare lean, base, and growth spending scenarios — and exactly how many months each one buys you.
It's built for directional planning: change any assumption and watch the whole projection move, the way a seasoned operator pressure-tests a plan before committing capital. Everything is computed live in your browser — nothing is sent anywhere.
How the Cash Runway Scenario Simulator Works
The model takes 2 assumptions and returns 3 headline metrics plus a full breakdown. Here is exactly what goes in and what comes out — no black box.
The Inputs
| Assumption | Example value |
|---|---|
| Cash in bank | $500,000 |
| Base monthly burn | $80,000 |
Worked Example
Every figure below is produced by the live model using the example assumptions above. Change any input in the simulator to see your own numbers.

The Operator's Read
Base case gives you about 6.3 months. Decide which scenario you're in *before* the market does — raise or cut with 9–12 months left, never 3.
Assumptions & Limitations
- •The model is deterministic: it projects your inputs forward with clear arithmetic, not a Monte-Carlo or probabilistic forecast. It shows one scenario at a time — run several to bracket a range.
- •Defaults are illustrative benchmarks, not your business. Replace every field with your real numbers before drawing conclusions.
- •It abstracts away taxes, financing, seasonality, and one-off events unless a field explicitly captures them. Treat the output as a directional estimate.
- •This is an educational tool, not financial, investment, tax, or legal advice. Validate real decisions with a qualified professional.
Frequently Asked Questions
What does the Cash Runway Scenario Simulator calculate?
Enter cash and burn to compare lean, base, and growth spending scenarios — and exactly how many months each one buys you. It takes 2 assumptions — Cash in bank, Base monthly burn — and returns Lean runway, Base runway, Growth runway, along with a full projection table you can export.
How do I use the Cash Runway Scenario Simulator?
Enter your own figures in the input fields above — Cash in bank, Base monthly burn, and the rest. The model recalculates instantly and shows the resulting Lean runway and full breakdown. No sign-up needed to run it.
Is the Cash Runway Scenario Simulator free?
Yes — you can run the simulator and see the headline results for free. Toolkit Pro unlocks the full projection table, Excel/PDF export, saved scenarios, and AI analysis: $180/mo, $1,728/yr, or unlock any 3 simulators for $20.
What's the difference between this and a free calculator?
A calculator answers one question. This simulator models the full picture — multiple linked assumptions, a projection table, and scenario comparison — the way an operator would build it in a spreadsheet, but instantly.
Who built the Cash Runway Scenario Simulator?
The Crimson Bench's Ivy League-educated operators — the same people we deploy into C-suites. This is the self-serve version of a model they'd build inside a live engagement.
Is this financial advice?
No. The Cash Runway Scenario Simulator is an educational modeling tool for directional planning — not financial, investment, tax, or legal advice. Validate any real decision with a qualified professional.
