You should pay no more for lead generation than your gross margin per job allows — and for most cabinet and remodeling businesses at 25% close rate and 10% acquisition budget, that ceiling lands around $150–$400 per exclusive lead.
Not sure where your ceiling is? Run the ROI calculator — enter your job value, close rate, and margins, and the model outputs your max acceptable cost per lead in under two minutes.
What Should Your Maximum Lead Cost Be?
Your maximum sustainable lead cost is a function of job value, gross margin, your target acquisition budget percentage, and your close rate — not what a vendor charges or what the industry average is.
The SBA’s guideline for businesses under $5M in annual revenue is 7–8% of gross revenue for marketing when net margins are in the 10–12% range, per CommonMind (CommonMind). That gives you the total budget. From there, back out to a per-lead ceiling using your actual close rate.
A $30,000 kitchen remodel at 30% gross margin gives you $9,000 in job budget before overhead and owner pay. If you allocate 10% of that to acquisition ($900 per booked job maximum), and your close rate on qualified leads is 25%, your maximum acceptable cost per lead is $225. At a 10% close rate, that same $900 per booked job ceiling means you can’t pay more than $90 per lead.
The math makes decisions simple. Any channel that exceeds your ceiling at your real close rate is unprofitable — regardless of how cheap the sticker looks.
How Does Real Cost Per Booked Job Differ by Channel?
Exclusive leads produce a far lower real cost per booked job than shared leads, even when the sticker price is higher — because exclusivity lifts close rates from 5–15% to 20–35%.
Here’s a channel comparison using verified 2026 benchmark data from LocaliQ and WordStream:
| Channel | Typical cost per lead | Exclusivity | Typical close rate | Cost per booked job |
|---|---|---|---|---|
| Google LSA | $25–$80 | 100% yours | 20–35% | $71–$400 |
| Google Search Ads | $90.92 avg (home services) | 100% yours | 20–35% | $260–$455 |
| Facebook/Instagram | $41.26 avg (Home Improvement) | 100% yours | 10–20% | $206–$413 |
| Shared-lead platforms | $15–$150 | Shared 3–5 shops | 5–15% | $100–$3,000+ |
- Sold to 3–5 contractors at once
- Close rates: 5–15% (speed contest)
- Fees charged whether lead converts or not
- Builds nothing you own — stops when you stop
- Every lead is exclusively yours
- Close rates: 20–35% (no speed race)
- SEO leads compound — cost falls over time
- Ads buildable; SEO is a durable asset
CabinetBoost clients who track cost per booked job by channel consistently find their exclusive Google channels are cheaper per won job than their shared-lead subscriptions — even when the shared-lead sticker price looks lower.

When Should You Increase the Marketing Budget?
Increase lead-generation spend only after you know your cost per booked job by source — scaling a channel you haven’t measured just multiplies waste.
The signal to scale is a channel where your verified cost per booked job sits comfortably below your acquisition ceiling. If Google Ads campaigns for cabinet businesses delivers a $300 booked appointment on a $30,000 job at your current close rate, and your ceiling is $450, you have room to double the budget and still be profitable. If you don’t have that number by source, adding budget accelerates the spend, not the profit.
The signal to pause is the reverse: a channel costing more per booked job than your ceiling, or one where close rate data doesn’t exist yet. Shared-lead platforms are where most remodeling businesses discover this — the sticker looked manageable, the real cost per booked job didn’t.

What’s the Honest Formula for Maximum Lead Cost?
Maximum cost per lead = (Gross Margin per Job × Acquisition %) ÷ Close Rate. This is the only formula that connects your P&L to your lead spend — everything else is a guess.
This discipline protects margins. Cabinet and remodeling businesses that skip this calculation often chase cheap-sticker leads straight into unprofitable jobs — spending more on acquisition than the job returns, without realizing it until they look at annual margin.
The two inputs to track monthly: close rate by source (your CRM or a simple spreadsheet), and cost per lead by source (your ad dashboards or agency reporting). Everything else follows from those two numbers.
What’s the Right Program for a Remodeling Business in 2026?
Exclusive channels — Google Ads, Local Services Ads, and SEO — produce the lowest real cost per booked job for most established cabinet and remodeling businesses. The question is which to run first and how to sequence them.
Bienal Closets came to CabinetBoost generating inquiries at $234 per lead through a poorly structured campaign. After rebuilding the campaign architecture, cost per lead dropped to $47 within 90 days — a real booked-job cost that made it straightforward to scale. That’s what the right exclusive channel setup produces once the structure is correct.
Our offer is built around that result: 20 showroom appointments in 90 days, or you don’t pay. Month-to-month after the guarantee window, no long contract required.
