A practical cash runway scenario
For this example, use cash available of 240,000, monthly cash revenue of 32,000, monthly cash spending of 58,000, and monthly spend growth of 1.5 %. These are starting values, so replace them with numbers that match your situation.
Cash available: 25% lower
Change cash available to 180,000 while keeping the other example values the same.
Cash available: 25% higher
Change cash available to 300,000 while keeping the other example values the same.
