Runway

Runway is the single most useful number in Insights. It answers one question: at the current rate of money in and money out, how many months until cash hits zero?

How we compute it

runway (months) = cash on hand / burn rate
burn rate       = monthly expenses − monthly revenue

If your monthly revenue exceeds your expenses, your burn rate is negative — you’re growing cash, and runway is effectively unbounded. We show that as “∞” rather than a number.

What “cash on hand” means

The sum of current balances across all bank accounts you’ve connected or added manually under Settings → Banking. If you’ve only connected one bank, that’s your only signal. If you keep an operating account and a tax-set-aside account, both count.

Heads up: pending invoices don’t count toward cash on hand. They’re already revenue (recognized when sent), but they’re not cash until the bank transaction shows up and you mark the invoice paid.

What “monthly revenue” and “expenses” mean

Both are computed from categorized transactions over the selected date range, normalized to a monthly figure. Uncategorized transactions don’t count — that’s why the Transactions page nudges you to keep up on categorization.

How to use it

A long runway is comforting but not always actionable. Watch the trend — runway shrinking month over month is a leading indicator that you’re spending faster than you’re earning, even if the absolute number still looks fine.

Caveats

• Runway treats your expenses as constant. A one-off equipment purchase will spike your burn rate for that month and shorten runway artificially.
• It doesn’t model expected revenue from invoices not yet sent. If you know a big project is about to bill, runway will look worse than reality.
• It assumes all cash on hand is operating capital. If you’ve set aside a tax reserve or a rainy-day fund, mentally subtract it before reading runway.
