Your operation's heat map: how to identify screens that profit and screens that drain margin

Not every screen that bills is profitable. And not every low-revenue screen is a loss. The difference lies in the individual P&L of each face — and almost no operator does this math.

You have 40 screens. You bill R$ 120,000 a month. You're growing. Everything looks fine. Until you sit down and do the math you've never done: how much each screen costs versus how much each screen generates. When you do, you discover that 8 of your 40 screens operate in the red — rent, energy, and maintenance add up to more than the revenue they produce. And that 6 screens alone account for half your profit.

Without this view, you're flying blind. You add new screens without knowing if they'll be profitable. You renew site leases without knowing if the screen pays for itself. And worst of all, you subsidize bad screens with the margin from good ones — thinking you're growing, when in fact you're diluting profitability.

This article teaches you how to build your operation's heat map: the P&L per screen, the decision matrix, and the right actions for each quadrant.

The Pareto problem you can't see

In nearly every OOH operation, profitability follows the Pareto principle: a minority of screens generates the majority of profit. That's not a problem — it's natural. The problem is not knowing which screens those are.

Typical profitability distribution

20 / 80

In operations without per-screen management, roughly 20% of screens generate 80% of the margin. The other 80% split the remaining 20% — and a significant portion operates at negative margin without the operator knowing.

Your most profitable screen may not be your highest-billing one. And your highest-billing screen may not be profitable at all. Without the individual P&L, you can't tell the difference.

Anatomy of a screen's cost

Before calculating margin, you need to know everything each screen costs. Most operators know the rent — and stop there. But the real cost includes at least 6 components:

🏢

Site rent / Lease

Payment to the landowner, building, condo, or commercial point where the equipment is installed. Usually the largest fixed cost. Ranges from R$ 200/mo (elevator screen) to R$ 5,000+/mo (LED panel on a premium avenue).

⚡

Electricity

LED panels consume 300W to 2,000W depending on size and brightness. Running 12–18h/day, monthly cost can range from R$ 150 to R$ 1,500. Elevator screens consume minimal power (R$ 15–30/mo).

🔧

Maintenance

Preventive (cleaning, quarterly inspection) and corrective (LED module swap, burned power supply, control board). Budget 2–5% of equipment value per year. A screen without preventive maintenance breaks more often — and every idle day is zero revenue.

📜

Permits / Licensing

Annual municipal licensing fee for outdoor media. Varies by city: from R$ 500/year to R$ 5,000+/year in heavily regulated capitals. Some municipalities charge per m² of face.

📉

Equipment depreciation

An LED panel that cost R$ 80,000 has an 8–12 year lifespan. Divided monthly, that's R$ 550–830/mo in depreciation. Many operators ignore this cost — and are surprised when they need to replace equipment.

🌐

Connectivity and insurance

Internet/4G for remote management (R$ 50–150/mo) and insurance against vandalism, weather, or theft. Small individually, but across 50 screens they add up.

The math nobody does

Add up all the costs above for a single screen and divide by month. That's the real monthly cost of the screen. Now compare it with the revenue that screen generated in the same month. If cost exceeds revenue, the screen is in the red — and it's being subsidized by the screens that are profitable.

How to calculate the P&L per screen in 5 steps

List every screen in the operation

Each face, display, or panel is one row. Include location, equipment type, and operation start date.

Fill in the monthly revenue per screen

How much that specific screen billed over the last 3 months, averaged. Use net revenue (after agency commission and taxes). If the screen was empty any month, that month's revenue is zero — and it impacts the average.

Fill in all monthly costs per screen

Rent + energy + prorated maintenance + prorated permits + depreciation + connectivity + insurance. Add it all up. That's the total monthly cost of the screen.

Calculate the margin (revenue minus cost)

Average monthly revenue minus total monthly cost. If positive, the screen contributes to profit. If negative, it drains.

Classify and rank

Sort all screens by margin, highest to lowest. Color the top 25% green, the middle yellow, and the bottom 25% red. That's your heat map.

Practical example

Screen	Revenue/mo	Cost/mo	Margin	% Margin
LED Av. Brasil	R$ 12,000	R$ 4,200	+R$ 7,800	65%
Billboard BR-040	R$ 4,500	R$ 1,100	+R$ 3,400	76%
Elevator Screen Ed. Central	R$ 800	R$ 250	+R$ 550	69%
LED Rua das Flores	R$ 6,000	R$ 5,400	+R$ 600	10%
Panel Shopping Norte	R$ 3,200	R$ 3,800	−R$ 600	−19%

Notice the Billboard BR-040 bills less than the LED Rua das Flores, but has 76% margin versus 10%. And the Elevator Screen, with just R$ 800 in revenue, delivers 69% margin — because it costs R$ 250. Revenue is not margin. The heat map reveals the truth that billing hides.

The 4 quadrants: the decision matrix

Quadrant 1

Star ⭐

High revenue + high margin. Your best screens. Generate volume and profit. Example: LED on a high-traffic avenue with negotiated rent and high occupancy.

→ Protect, lock in long-term site lease, use as template for expansion

Quadrant 2

Cash cow 🥛

Low revenue + high margin. Modest but highly efficient screens. Example: elevator screen that bills little but costs almost nothing. Silent profit.

→ Keep, scale the model (more units of the same type), never sacrifice for "bigger" screens

Quadrant 3

Question mark ❓

High revenue + low margin. Bills well but cost eats almost everything. Example: premium LED in a mall with sky-high rent. Looks good on the report, but little is left.

→ Renegotiate rent, raise selling price, cut operating cost. If nothing works, evaluate exit

Quadrant 4

Drain 🚫

Low revenue + negative margin. Costs more than it generates. Example: billboard in a secondary location with low demand and unjustifiable rent.

→ Cut. Renegotiate only if there's clear potential. Every month it stays is cash leaving

The emotional trap

Many operators keep red screens out of attachment: "it was my first panel," "the location looks nice," "it'll sell eventually." The heat map eliminates emotional bias. If the screen hasn't paid for itself in 6 consecutive months and there's no concrete plan to change that, it's time to exit.

The action plan for each quadrant

Stars: protect and replicate

Your star screens are the most valuable in the operation. The action is both defensive and expansive: renew the site lease for the longest possible term, study what makes this screen profitable (location? low cost? high demand? all three?), and look to replicate the same conditions in new screens. When expanding, the criterion is: "does this new screen have the potential to be a star?"

Cash cows: don't underestimate them

It's tempting to ignore the screen that bills R$ 800/month. But if it costs R$ 250, it's delivering 69% margin with zero hassle. Cash cows are the backbone of the operation — they generate steady profit with low risk. The action is to scale: if one elevator screen works this way, 20 elevator screens become a recurring revenue pillar.

Question marks: decide in 90 days

Question marks demand intervention. You have three levers: cut the cost (renegotiate rent, optimize energy, switch maintenance contract), increase revenue (raise the price, improve prospecting for that screen, bundle it into packages), or both. Give it 90 days. If margin doesn't improve to at least 20%, reclassify as a drain and act accordingly.

Drains: cut fast

Every month a drain screen stays active is money leaving the profit of your good screens. The action is simple: negotiate the lease exit, dismantle the equipment, and relocate it to a screen with better potential. If the equipment is old and relocation doesn't make sense, sell it. Capital stuck in a bad screen is capital that could be in a good one.

Cutting a bad screen isn't failure. It's the most profitable decision you can make. Every real that stops leaving the cash register is a real that returns to margin.

When to review the map

The heat map isn't static. Demand shifts, costs change, site leases expire and get renegotiated. The recommendation is quarterly review with three questions:

🔄

Has any screen changed quadrants?

A star that became a question mark (rent went up, demand dropped) needs immediate attention. A drain that became a cash cow (cost renegotiated) can stay.

📊

Has revenue concentration changed?

If the top 5 screens now generate 70% of profit (it was 50%), you're becoming more dependent — and more vulnerable. Diversify.

📍

Where do new screens land?

If the last 5 new screens are all question marks or drains, your expansion criteria are wrong. Go back to the analysis before adding more.

💰

Has any site lease cost increased?

Landlords renegotiate upward. If the increase pushes the screen to negative margin and you can't pass it through in selling price, it's time to evaluate the exit.

The expansion criteria the map teaches

Once you have the heat map, the decision to expand changes completely. Instead of "there's a spot available on Avenue X, I'll take it," the question becomes:

What's the projected total monthly cost of this screen?

Rent + energy + maintenance + depreciation + permits. Add it up before signing.

What's the minimum monthly revenue it needs to generate 30%+ margin?

If cost is R$ 3,000/mo, minimum revenue for 30% margin is R$ 4,300. Is there enough demand in the area to sustain that?

Does this new screen look more like a star or a drain?

Compare characteristics (location, traffic, venue type, cost) with screens already on your map. If it resembles your drains, rethink. If it resembles your stars, move forward.

What's the equipment payback period?

If the LED cost R$ 80,000 and projected monthly margin is R$ 5,000, payback is 16 months. Acceptable. If margin is R$ 800, payback is 100 months (8 years). Unviable.

The organized operator's rule

Never add a new screen without calculating the projected P&L. If it doesn't work on paper, it won't work on the street. Your current heat map is the teacher: it shows which characteristics generate profit and which generate headaches.
