Show the math

Estimates use unrounded numbers. Displayed amounts round to cents.

What this means

Runway divides available cash after immediate costs by net recurring cash burn. Accounting profit and bank cash flow are different quantities.

Worked example

$10,000 starting cash minus $2,000 immediate expenses leaves $8,000. $3,000 monthly outflows minus $1,000 inflows burns $2,000/month, giving four months.

How the math works

Available A = starting cash−one-time expenses. Burn B = monthly outflows−monthly inflows. If A≥0 and B>0, months=A/B. An immediate shortfall gives zero remaining runway. If B≤0 and no immediate shortfall exists, there is no finite depletion date in this constant scenario.

About this estimate

Inflows/outflows stay constant and occur uniformly through each month. No revenue growth, financing, emergency reserve, payment timing or forecast probability is assumed. Nonnegative cash flow is an indication for this scenario, not a guarantee.
