How is this calculated?

Runway risk scores your runway against the safe band, your burn against revenue growth, and this week's conditions. Growth compounds monthly. Burn is compared with monthly revenue: monthly burn divided by monthly revenue, read as 4x with no revenue and never above 4x, so earning something never scores worse than earning nothing.

Runway is worked out from it.

Or leave it blank, enter your cash, and we'll work it out.

Everything you spend in a month, before revenue.

Monthly growth. Leave it blank for no growth.

Enter cash in the bank (or runway), monthly spend, and monthly revenue to size the plan.

Your figures stay in this browser and are shared with the plan stress test.
