Remodeling by the Numbers: Markup vs. Margin, Backlog in Weeks and a 10-Line Monthly Scorecard

Plenty of remodeling companies with $2 million to $5 million in revenue run on a bank balance and a feeling. Busy means good, slow means worry. The trouble is that by the time the bank balance tells you something, the decision that caused it was made two or three months earlier, when a proposal was priced too thin or marketing was paused because the crews were slammed.

This article gives you the handful of numbers that actually predict how a remodeling business will do, how to calculate them, and a monthly scorecard you can fill out in under an hour.

Benchmark yourself against real remodeler data

NAHB’s 2026 Remodelers’ Cost of Doing Business Study, which reports 2024 results, found an average gross profit margin of 29.9 percent and a net profit margin of 6.3 percent, the highest net margin since 1996. The study summary puts average revenue at $2.7 million, cost of sales at 70.1 percent of revenue and operating expenses at 23.6 percent. NAHB also notes that trade contractor costs fell from 36 percent of revenue in 2021 to 30 percent in 2024.

Use these as a reference point, not a target. Design-build firms with in-house design often need higher gross margins to cover sales and design overhead; firms that subcontract most trades may run lower gross margins with lighter overhead. What matters is that your gross margin reliably covers your operating expenses and leaves the profit you want.

Fix the markup-versus-margin mistake first

This is the most expensive arithmetic error in remodeling. Markup is a percentage of cost. Margin is a percentage of the selling price. They are not interchangeable.

Markup on job cost	Resulting gross margin
25%	20.0%
30%	23.1%
40%	28.6%
43%	30.1%
50%	33.3%
67%	40.1%

The formulas: margin = markup ÷ (1 + markup), and markup = margin ÷ (1 − margin). To reach a 30 percent gross margin, you need roughly a 43 percent markup on direct job costs.

Illustrative example: a bathroom with $35,000 in direct costs (labor, materials, subs, dumpster, permit). A 30 percent markup prices it at $45,500, a gross profit of $10,500 and a 23.1 percent margin. A 43 percent markup prices it at $50,050, a gross profit of $15,050 and a 30.1 percent margin. On 40 similar jobs a year, that difference is about $182,000 of gross profit.

Track gross margin by job type

A company-wide margin can hide a losing product line. Tag every completed job by type (kitchen, bath, basement, addition, whole-home, small repair) and calculate actual gross margin for each type every quarter. Many remodelers discover that one category, often small repairs or heavily customized whole-home jobs, consistently earns well below the rest because of drive time, return trips or unpriced design hours.

Once you can see it, you have three options: reprice that work, set a minimum job size, or stop marketing it. Each is better than continuing to subsidize it with your profitable kitchens and baths.

Price for the material market you are in

Margins erode quietly between proposal and purchase. In NAHB’s second-quarter 2026 Remodeling Market Index, 74 percent of remodelers reported supplier price increases since March, averaging 6.7 percent. Three protections:

• Short price validity. 30 days on proposals, stated clearly.
• Allowances for volatile selections. Cabinets, tile, fixtures and appliances as allowances with a clear reconciliation process.
• Escalation language on long-lead or long-duration projects, reviewed by your attorney for your state.

Read seasonality as a sales cycle

Remodeling demand has seasonal patterns that vary by region and project type, and the key point for planning is that you sell months before you build. A kitchen that starts in May may have been first discussed in February; an addition that starts in September may have started with a phone call the previous winter.

Use your own history instead of rules of thumb:

1. For every signed job in the last two to three years, record three dates: first contact, contract signed and construction start.
2. Chart leads by month and contracts by month. Note the gap between them.
3. Plan marketing to peak one sales cycle before the production months you most need to fill.

The macro trend matters too. Harvard’s Joint Center for Housing Studies projected in May 2026 that homeowner improvement spending would grow only about 0.5 percent year over year by early 2027, reaching $523 billion. In a flat market, a company that plans marketing ahead of its slow months wins share from competitors that react late.

Backlog: the number that predicts next quarter

Backlog in weeks is signed, scheduled work divided by weekly production capacity. Remodelers nationally feel this too: NAHB’s backlog indicator fell to 54 in the second quarter of 2026, with leads and inquiries at 51.

Set three zones for your company:

• Healthy: backlog longer than your average sales cycle plus four weeks. Keep marketing steady and hold pricing.
• Watch: backlog roughly equal to your sales cycle. Turn up demand channels and past-client outreach now.
• Danger: backlog shorter than your sales cycle. You will have idle crews before new work can start. Act on demand and on smaller, faster-to-start projects.

CAC and lifetime value, in remodeling terms

Customer acquisition cost (CAC) for a remodeler is total sales and marketing cost for a period divided by new contracts signed. Include ad spend, lead fees, website and software, salesperson or estimator time spent selling, and design time on proposals that did not sign.

Lifetime value is the gross profit a client generates across all their projects, plus the gross profit from the referrals they send. You will not have this perfectly, but even a rough estimate changes decisions.

Illustrative example: a remodeler spends $96,000 a year on marketing and sales time and signs 32 contracts, so CAC is $3,000. The average first project is $48,000 at a 30 percent gross margin, or $14,400 of gross profit. If one in five clients does a second project and one in four sends a referral that signs, each client is worth noticeably more than the first job alone. Spending $3,000 to earn $14,400 of gross profit on the first project is healthy. Spending $3,000 to win a $9,000 job at 22 percent margin, or $1,980 of gross profit, is not.

The 10-line monthly scorecard

Review this on the same day every month with whoever runs sales and production.

#	Metric	How to calculate
1	Leads by source	Count of new inquiries, tagged by channel
2	Median time to first contact	Minutes from inquiry to first real conversation
3	Site visits	Qualified consultations held
4	Proposal close rate	Contracts signed ÷ proposals presented
5	New contract value	Total signed this month, and average per contract
6	Backlog in weeks	Signed, unbuilt work ÷ weekly production capacity
7	Estimated vs. actual gross margin	On jobs closed out this month
8	Cost per signed contract	Sales and marketing cost ÷ contracts signed (rolling three months)
9	Repeat and referral share	Share of new contracts from past clients and their referrals
10	New reviews and most recent review date	Count this month, and days since the latest

Lines 1 through 5 show the sales funnel, line 6 predicts cash flow, line 7 protects profit, and lines 8 through 10 tell you whether growth is getting cheaper or more expensive over time.

Turn the numbers into decisions

• Backlog dropping and close rate steady: you need more demand. Turn up the channels with the lowest cost per signed contract.
• Plenty of leads, low close rate: fix qualification, proposal presentation and follow-up before spending more.
• Close rate high, margins slipping: you may be underpriced. Test a higher markup on your next ten proposals.
• Repeat and referral share falling: look at closeout quality and past-client follow-up.

None of this requires expensive software to start; a spreadsheet and a CRM with source tracking are enough. If you want a structured view of how your numbers, funnel and channels fit together, Bluma’s free Growth Assessment gives you a starting score and the first areas to fix.
