A plain-English explanation of cash runway logic, variable meanings, and edge cases that confuse most users.
Most “wrong answers” are input problems, not calculator problems. A quick pass through the cash runway logic makes it easier to enter the right numbers.
If you can explain how starting cash, burn, and collections/revenue connects to runway months and cash-out estimate, you’re unlikely to be fooled by a fragile scenario.
The calculator translates your inputs into a consistent model so you can compare scenarios with the same rules.
Change one variable at a time and confirm the output direction matches intuition.
Most sensitivity lives in 2–3 fields: starting cash, burn, and collections/revenue.
When the result surprises you, simplify the scenario and confirm each field definition.
Avoid impossible combinations (negative values, unrealistic rates, mismatched time horizons).
If the outcome is close to your threshold, run a conservative downside case before deciding.
