The One Number Every Founder Should Check Every Monday

Devon Wright runs a 14-person creative agency in Atlanta. Every Monday at 7:42 a.m., before he opens email, before he talks to a client, before he so much as touches Slack, he does one piece of math.

Cash on hand divided by weekly burn. That's it. Nine minutes, a calculator, a notebook. He's done it 312 weeks in a row.

"It's the only number that tells me how much time I actually have," he says. "Revenue tells me what happened. Profit tells me what theoretically happened. Runway tells me what's about to happen."

He's right, and almost nobody does it. Most accounting software won't surface this number. Most accountants, asked for it, will hand you a monthly version that flatters the truth. The weekly version is the one that matters because cash crises arrive in weeks, not quarters.

Here's the difference it makes. When your runway is short, every decision is defensive. You sharpen quotes to win jobs at margins you can't really afford. You delay hires even when the work justifies them. You let vendor relationships fray in ways that compound late payments turn into stricter terms, stricter terms turn into higher prices, higher prices turn into thinner margins, thinner margins turn into shorter runway. The loop is vicious and quiet.

When runway is long, every decision is strategic. Suppliers offer you discounts because you can pay on delivery. The right hire shows up at the right moment and you can actually make the offer. The business stops reacting and starts choosing.

Devon's target is sixteen weeks. When the number drifts under twelve, he doesn't panic he acts. Sometimes he accelerates collections. Sometimes he postpones a discretionary spend. Twice in the last three years, he's drawn on a pre-arranged capital line to keep the runway long enough to make non-defensive decisions.

"The line cost me about $400 a year to keep open," he says. "It's saved me from at least three decisions I would've regretted."

Try it Monday. Open your bank account. Add up the next four weeks of obligations. Divide. Write the number down. Do it again the following Monday. The act of writing it down is most of the work what you do with the number tends to take care of itself once you can see it.
