What are you counting on to keep the business going over the next six months? Required

Your numbers

Cash balance today

Monthly revenue

Monthly expenses

A/R balance (what customers owe you now, enter 0 if none)

Every box above is required, including the question. If one is genuinely zero, type 0 — a blank box and a zero are not the same answer.

Here's what we see in those numbers:

Days Sales Outstanding

—

Net monthly burn

—

Cash-only runway

—

Full runway

—

runway card

Your runway

—

Days to collect A/R

—

Net monthly burn

—

expenses minus revenue

Cash-only runway

—

if A/R stalls entirely

This is one dial in your cockpit. The same gap between the story you tell yourself and what the cash actually does shows up in your pricing, your customer mix, and your hiring decisions too. Want me to look at the rest?

How to read this

What you are reading is arithmetic on the numbers you gave us. It is honest arithmetic, but it only knows what you typed — not your season, not the customer who always pays late, not the invoice landing next Tuesday. You know those things and this page does not. Use it to decide where to look, then check what you find against what you know.

Where we draw the line between comfortable and thin is our judgment, not a rule of accounting. Your bank, your accountant, or your own gut may draw it somewhere else.
