Guide

Runway and burn rate

Define burn and runway so they match actual cash, including card settlement and the risk of cash-linked limits.

Key takeaways

  • Vendor-neutral. Confirm specifics with any provider you evaluate.
  • No rates, rankings or affiliate links.

Pick a definition and keep it

Gross burn vs net burn. Include or exclude one-off items on purpose. Changing the definition to “make runway look longer” is how boards lose trust.

Card interaction

If limits follow cash, a burn spike can cut purchasing power. Do not assume the card is a shock absorber.
