What five numbers should a $1M–$5M business owner check every month?

The five numbers that matter most are gross margin, cash runway, accounts receivable aging, labor cost as a percentage of revenue, and net profit margin — tracked as a trend, not a single snapshot. Most owners in this revenue range look at one number (usually the bank balance) and skip the other four. That’s how a profitable year on paper turns into a cash crunch in March.

Why these five and not twenty

You could track fifty line items every month. Nobody does, because nobody has time. After 40+ years working with businesses in this revenue range, we’ve found the same five numbers separate the owners who scale from the ones who plateau — and the other forty-five mostly explain why one of these five moved.

1. Gross margin — is the core business getting more or less profitable?

Gross margin is revenue minus the direct cost of delivering your product or service, shown as a percentage. A contractor’s gross margin includes materials and job-site labor. A restaurant’s includes food and beverage cost. It does not include rent, admin salaries, or marketing.

Where to find it: the top of your profit and loss statement, usually labeled “Gross Profit” with a percentage next to it.

What to watch for: a gross margin that’s slipping quarter over quarter, even while revenue is growing. That’s usually a pricing problem, a cost problem, or both — and it’s invisible if you only look at the bottom line.

2. Cash runway — how many weeks could you operate if revenue stopped tomorrow?

Cash runway is your cash on hand divided by your average weekly operating expenses. It answers a different question than “how much cash do we have” — it tells you how much time that cash actually buys you.

Where to find it: your bank balance, divided by your average weekly burn from the last three months. Most accounting software doesn’t calculate this automatically — your bookkeeper should be handing it to you.

What to watch for: runway under four to six weeks for most $1M–$5M businesses is tight. Seasonal businesses (restaurants, contractors) need more, not less, because the slow season is predictable and the cash needs to be there when it arrives.

3. Accounts receivable aging — how much of your revenue is still a promise, not cash?

AR aging breaks out what customers owe you by how long it’s been outstanding — current, 30 days, 60 days, 90-plus days. A business can look profitable and still run out of cash if too much revenue is sitting in the 60- and 90-day buckets.

Where to find it: the AR Aging Summary report in QuickBooks Online, or the equivalent in your accounting software.

What to watch for: any meaningful balance in the 90-plus column. That money gets harder to collect every week it sits there, and it’s the single most common reason a profitable-on-paper business feels broke.

4. Labor cost as a percentage of revenue — is your biggest expense staying in line?

For most businesses in this revenue range, labor is the largest controllable expense. Tracking it as a percentage of revenue — not just a dollar total — shows whether it’s growing faster than the business.

Where to find it: total payroll cost (wages plus employer taxes and benefits) divided by total revenue, for the same month.

What to watch for: a labor percentage that creeps up over several months without a matching jump in revenue. That’s a staffing, scheduling, or overtime issue worth catching before it becomes a full quarter’s trend.

5. Net profit margin — trend, not snapshot

Net profit margin is what’s left after every expense, shown as a percentage of revenue. The number itself matters less than the direction it’s moving over six to twelve months.

Where to find it: the bottom line of your P&L, divided by total revenue.

What to watch for: a margin that’s flat or declining while revenue grows. Growing revenue with shrinking margin usually means growth is being bought with lower prices, higher costs, or both — worth catching well before year-end.

The 5 numbers at a glance

Cash runway (weeks)	Bank balance ÷ weekly burn	Under 4–6 weeks
AR aging (90+ days)	AR Aging Summary report	Any meaningful balance
Labor cost % of revenue	Payroll cost ÷ revenue	Creeping up without revenue growth
Net profit margin trend	Bottom of P&L, 6–12 mo. view	Flat or falling while revenue rises

What this means for you

• Pull these five numbers monthly, not just at tax time — by the time your CPA sees a full year of numbers, the trend has already played out.
• Ask for them as a trend line (6–12 months), not a single month. One bad month is noise. Three bad months in a row is a pattern.
• If you can’t find one of these five numbers in ten minutes, that’s a bookkeeping gap worth fixing before it’s a cash gap.
